Why Defender XDR Is Mandatory

1
00:00:00,000 –> 00:00:04,440
You’ve got six dashboards, three vendors, and a color-coded incident spreadsheet.

2
00:00:04,440 –> 00:00:09,600
Congrats, you built a Rube Goldberg machine that alerts loudly and catches little.

3
00:00:09,600 –> 00:00:12,520
Hybrid security isn’t more tools.

4
00:00:12,520 –> 00:00:16,360
It’s two overlapping attack surfaces pretending to be one.

5
00:00:16,360 –> 00:00:18,200
Here’s what most people miss.

6
00:00:18,200 –> 00:00:21,200
Your silos hide four blind spots.

7
00:00:21,200 –> 00:00:25,720
M365 endpoints, identities, and cloud apps.

8
00:00:25,720 –> 00:00:31,320
I’ll show you how attackers live in those gaps and how Defender XDR closes them by turning

9
00:00:31,320 –> 00:00:34,040
chaos into a single incident story.

10
00:00:34,040 –> 00:00:38,800
There’s one capability that flips Defender XDR from expense to savings.

11
00:00:38,800 –> 00:00:40,200
Hold that thought.

12
00:00:40,200 –> 00:00:44,840
First, let’s talk about why the silo habit keeps burning you.

13
00:00:44,840 –> 00:00:48,320
Why siloed security fails in hybrid environments?

14
00:00:48,320 –> 00:00:49,360
Foundation?

15
00:00:49,360 –> 00:00:50,680
Hybrid isn’t new.

16
00:00:50,680 –> 00:00:52,040
It’s just messier.

17
00:00:52,040 –> 00:00:57,480
You’ve got on-prem AD still limping along Azure AD doing the real work.

18
00:00:57,480 –> 00:01:03,080
Laptops phoning in from questionable Wi-Fi and SAS apps approved by someone who swears

19
00:01:03,080 –> 00:01:05,120
they ask security.

20
00:01:05,120 –> 00:01:09,480
That’s four lanes of traffic, no stoplights, and you’re shocked there are collisions.

21
00:01:09,480 –> 00:01:12,160
Now the part nobody likes to say out loud.

22
00:01:12,160 –> 00:01:15,320
Every separate tool creates context debt.

23
00:01:15,320 –> 00:01:18,600
Email sees a fish, identity flags, an odd sign in.

24
00:01:18,600 –> 00:01:21,320
Endpoint notices a weird power shell chain.

25
00:01:22,320 –> 00:01:26,480
Cloud app security waves at a rogue O-auth consent.

26
00:01:26,480 –> 00:01:28,600
Individually they look low.

27
00:01:28,600 –> 00:01:34,200
Together it’s an active intrusion but your tools don’t share memory so your team becomes

28
00:01:34,200 –> 00:01:40,800
the RAM, copying, pasting, reconciling timestamps, guessing which alert came first.

29
00:01:40,800 –> 00:01:42,800
That’s where dwell time blooms.

30
00:01:42,800 –> 00:01:45,760
Alert fatigue isn’t a feeling, it’s attacks.

31
00:01:45,760 –> 00:01:49,920
When your SOC pivots between consoles you multiply toil.

32
00:01:49,920 –> 00:01:54,000
This burn cycles correlating what should already be fused.

33
00:01:54,000 –> 00:01:57,720
Sender to user to token to device to app.

34
00:01:57,720 –> 00:01:59,280
That manual stitching?

35
00:01:59,280 –> 00:02:03,000
Slow, inconsistent and easy to get wrong at 2am.

36
00:02:03,000 –> 00:02:04,560
The attacker needs one gap.

37
00:02:04,560 –> 00:02:06,960
You hand them forward, you think the fix is more data.

38
00:02:06,960 –> 00:02:09,280
No, the fix is one timeline.

39
00:02:09,280 –> 00:02:12,920
Silo tools are great at telling you something happened.

40
00:02:12,920 –> 00:02:18,000
They’re terrible at telling you what happened in which order across domains.

41
00:02:18,000 –> 00:02:19,480
Sequence is the detection.

42
00:02:19,480 –> 00:02:22,560
Outed you’re left with vibes and a backlog.

43
00:02:22,560 –> 00:02:24,520
Here’s the financial part.

44
00:02:24,520 –> 00:02:30,400
Fragmentation inflates response time which inflates blast radius, which inflates cost.

45
00:02:30,400 –> 00:02:34,360
Meanwhile compliance turns into scavenger hunt theatre.

46
00:02:34,360 –> 00:02:37,640
Exporting CSVs from five places to prove you did anything.

47
00:02:37,640 –> 00:02:39,680
That’s not security.

48
00:02:39,680 –> 00:02:42,600
That’s paperwork.

49
00:02:42,600 –> 00:02:47,600
Everything clicked for me when I realized we aren’t under resourced, we’re over-fragmented.

50
00:02:47,600 –> 00:02:49,200
You don’t need another console.

51
00:02:49,200 –> 00:02:53,000
You need one incident graph that understands relationships.

52
00:02:53,000 –> 00:02:55,760
The mailbox rule that hid the fish.

53
00:02:55,760 –> 00:02:58,600
The consent grant that gave persistence.

54
00:02:58,600 –> 00:03:01,480
The token that bypassed MFA.

55
00:03:01,480 –> 00:03:07,560
The endpoint process that pulled payloads and the cloud session that exfiltrated data all

56
00:03:07,560 –> 00:03:12,600
tied to the same user and device end to end.

57
00:03:12,600 –> 00:03:15,480
Now you might say we have smart analysts.

58
00:03:15,480 –> 00:03:16,480
Sure.

59
00:03:16,480 –> 00:03:20,560
So does the attacker and they aren’t reconciling your alert IDs.

60
00:03:20,560 –> 00:03:24,800
They’re moving laterally while you argue over which timestamp is UTC.

61
00:03:24,800 –> 00:03:30,480
Back in my day, Exchange 2003 taught us about hidden rules the hard way.

62
00:03:30,480 –> 00:03:33,200
Today it’s the same trick with better marketing.

63
00:03:33,200 –> 00:03:36,200
Oauth consent instead of com add-ins.

64
00:03:36,200 –> 00:03:38,160
Different sticker, same mess.

65
00:03:38,160 –> 00:03:40,640
Market reality reflects this.

66
00:03:40,640 –> 00:03:44,320
XDR didn’t show up because vendors needed a new acronym.

67
00:03:44,320 –> 00:03:49,000
It showed up because multi-tool correlation failed at human speed.

68
00:03:49,000 –> 00:03:53,640
Organizations learned the hard way that you can’t manually glue identities, email endpoints

69
00:03:53,640 –> 00:03:57,440
and cloud apps and expect real-time detection.

70
00:03:57,440 –> 00:04:00,440
The growth in XDR adoption isn’t hype.

71
00:04:00,440 –> 00:04:03,200
It’s the penalty for ignoring causality.

72
00:04:03,200 –> 00:04:04,680
Here’s the weird part.

73
00:04:04,680 –> 00:04:07,800
Silo teams mirror silo tools.

74
00:04:07,800 –> 00:04:10,960
Email team quarantines a message and moves on.

75
00:04:10,960 –> 00:04:13,880
Identity team lowers a risk state and moves on.

76
00:04:13,880 –> 00:04:16,320
One point team clears an alert and moves on.

77
00:04:16,320 –> 00:04:17,320
Nobody owns the narrative.

78
00:04:17,320 –> 00:04:23,040
So, the incident survives because the system that should be telling the story doesn’t

79
00:04:23,040 –> 00:04:24,200
write one.

80
00:04:24,200 –> 00:04:28,120
What this actually means day to day, your containment isn’t.

81
00:04:28,120 –> 00:04:30,640
You pulled the email but left the token alive.

82
00:04:30,640 –> 00:04:34,160
You cleaned the device but left the Oauth grant intact.

83
00:04:34,160 –> 00:04:37,640
You reset the password but kept the malicious mailbox rule.

84
00:04:37,640 –> 00:04:40,040
That’s how reinfection loops happen.

85
00:04:40,040 –> 00:04:42,160
You feel haunted because you are.

86
00:04:42,160 –> 00:04:45,880
By artifacts you never saw in one place.

87
00:04:45,880 –> 00:04:49,040
Defender XDR treats hybrid as one organism.

88
00:04:49,040 –> 00:04:50,920
Not perfect but closer to the truth.

89
00:04:50,920 –> 00:04:57,200
It fuses signals from Microsoft 365, identity endpoints and cloud apps into a single incident

90
00:04:57,200 –> 00:04:58,200
with a causal chain.

91
00:04:58,200 –> 00:05:01,280
Okay, so basically it stops making you be the bus.

92
00:05:01,280 –> 00:05:06,440
The platform does the stitching, presents the sequence and this is key.

93
00:05:06,440 –> 00:05:10,520
Executes response across domains from the same pain.

94
00:05:10,520 –> 00:05:12,400
So IR isn’t magic.

95
00:05:12,400 –> 00:05:16,840
Its policy-driven muscle memory you wish your tier ones had at 3am.

96
00:05:16,840 –> 00:05:22,520
I’m think of siloed security like guarding a building with four dormant who never speak.

97
00:05:22,520 –> 00:05:24,240
Each sees a piece.

98
00:05:24,240 –> 00:05:32,360
A forged ID, a propped door, a delivery to the wrong floor, a badge swipe at midnight.

99
00:05:32,360 –> 00:05:36,400
None of them calls it in because each event alone is me.

100
00:05:36,400 –> 00:05:39,600
An XDR is the radionet and the floor plan.

101
00:05:39,600 –> 00:05:45,080
Suddenly it’s obvious there’s an intruder on level 3 and you lock the elevators.

102
00:05:45,080 –> 00:05:46,480
Here’s what most people miss.

103
00:05:46,480 –> 00:05:48,440
The cost of tooling is visible.

104
00:05:48,440 –> 00:05:50,920
The cost of correlation isn’t.

105
00:05:50,920 –> 00:05:52,840
Until the breach report.

106
00:05:52,840 –> 00:05:57,960
You pay for dwell time, for overtime, for audits, for misdetections.

107
00:05:57,960 –> 00:06:00,520
Then you pay again to rip and replace.

108
00:06:00,520 –> 00:06:03,360
Or you consolidate the story up front.

109
00:06:03,360 –> 00:06:05,560
We’ll get into the four blind spots next.

110
00:06:05,560 –> 00:06:12,160
M365 identities endpoints and cloud apps and I’ll show you where attackers live rent free

111
00:06:12,160 –> 00:06:15,640
and how defender XDR evics them by default.

112
00:06:15,640 –> 00:06:19,520
And yes, that expense to savings switch.

113
00:06:19,520 –> 00:06:23,320
It turns on when incidents finally have one timeline.

114
00:06:23,320 –> 00:06:25,040
Blind spot one.

115
00:06:25,040 –> 00:06:31,800
Microsoft 365, email and collaboration telemetry without identity fusion.

116
00:06:31,800 –> 00:06:35,880
Let’s start where most break and still begin, mail and collaboration.

117
00:06:35,880 –> 00:06:38,320
Fish lands, user clicks.

118
00:06:38,320 –> 00:06:42,000
You quarantine the message and pat yourself on the back.

119
00:06:42,000 –> 00:06:44,400
Except nothing meaningful changed.

120
00:06:44,400 –> 00:06:48,480
Because the blast moved from the mailbox to identity the moment the user handed over

121
00:06:48,480 –> 00:06:49,880
a token.

122
00:06:49,880 –> 00:06:50,880
Email is the door.

123
00:06:50,880 –> 00:06:51,880
The keys are elsewhere.

124
00:06:51,880 –> 00:06:54,200
Here’s what most people miss.

125
00:06:54,200 –> 00:07:01,200
Microsoft 365 throws off great telemetry, delivery events, safe links, verdicts, mailbox

126
00:07:01,200 –> 00:07:07,560
rule changes, teams file shares, useful but in a silo it’s just noise.

127
00:07:07,560 –> 00:07:13,520
You see fish delivered to five users, you yank it and declare containment.

128
00:07:13,520 –> 00:07:20,960
Meanwhile, one user consented to calendar assistant pro that wants red right across graph.

129
00:07:20,960 –> 00:07:25,800
The mailbox is quiet, but the attacker is now living on OAuth.

130
00:07:25,800 –> 00:07:31,000
Quarantine isn’t containment, it’s house cleaning after the thief left with your badge.

131
00:07:31,000 –> 00:07:35,280
Okay, so basically the simple version is you need the email story stitched to the sign

132
00:07:35,280 –> 00:07:37,320
in story and the device story.

133
00:07:37,320 –> 00:07:40,400
Defender XDR builds one incident out of that mess.

134
00:07:40,400 –> 00:07:46,080
The fish that hit outlook it shows up on the same timeline as the Azure AD sign in spike.

135
00:07:46,080 –> 00:07:51,360
The token issuance, the end point spawning a suspicious office child process and the cloud

136
00:07:51,360 –> 00:07:56,680
app session that started scraping files, same user, same device.

137
00:07:56,680 –> 00:08:01,920
One causal chain instead of four unrelated lows.

138
00:08:01,920 –> 00:08:03,520
Here’s the weird part.

139
00:08:03,520 –> 00:08:09,280
In a classic setup, the mailbox team kills the message but never sees that the accounts

140
00:08:09,280 –> 00:08:12,560
refresh token is still valid.

141
00:08:12,560 –> 00:08:18,960
Identity flags, risky sign in, lowers it after a password reset and calls it a day.

142
00:08:18,960 –> 00:08:24,120
End point removes a macro dropper but has no clue the user’s inbox now forwards invoices

143
00:08:24,120 –> 00:08:26,960
to an external Gmail via a hidden rule.

144
00:08:26,960 –> 00:08:29,160
You just built a re-infection loop.

145
00:08:29,160 –> 00:08:32,120
Clean device, dirty identity and vice versa.

146
00:08:32,120 –> 00:08:36,200
Defender XDR stops that loop because response spans domains.

147
00:08:36,200 –> 00:08:41,960
Auto IR can isolate the device that ran the unsigned office power shell chain, revoke

148
00:08:41,960 –> 00:08:49,000
the user’s active sessions and tokens, kill the malicious OAuth consent and roll back mailbox

149
00:08:49,000 –> 00:08:52,760
rules without you playing swivel chair.

150
00:08:52,760 –> 00:08:57,360
The analysis is bound with the approvals where you want them but fast.

151
00:08:57,360 –> 00:09:03,080
The analyst clicks into the incident, sees the process tree, the email header, the sign

152
00:09:03,080 –> 00:09:10,520
in IPs, the consent details and the file activity it’s not magic, it’s a single memory of what

153
00:09:10,520 –> 00:09:12,000
happened.

154
00:09:12,000 –> 00:09:13,880
Think of it like this.

155
00:09:13,880 –> 00:09:18,520
Email only tools or bouncers who throw out the flyer, not the guy who already slipped

156
00:09:18,520 –> 00:09:25,520
inside.

157
00:09:25,520 –> 00:09:29,840
Same event, different outcome because sequence and scope are known.

158
00:09:29,840 –> 00:09:32,520
ROI isn’t hand-wavy here.

159
00:09:32,520 –> 00:09:39,160
When email identity and endpoint are fused, false positives drop because weird email, without

160
00:09:39,160 –> 00:09:42,240
weird login, stays alo.

161
00:09:42,240 –> 00:09:46,920
Trish time shrinks because you aren’t guessing which alert came first.

162
00:09:46,920 –> 00:09:52,520
But it’s stop being scavenger hunts because the incident record already shows mailbox actions,

163
00:09:52,520 –> 00:09:57,160
token revocations and device containment with timestamps.

164
00:09:57,160 –> 00:10:01,080
MicroStory you’ve lived, quarantined fish but the token lived.

165
00:10:01,080 –> 00:10:07,280
User keeps getting hit, you rotate passwords, wipe the laptop and the unknown app still hoovers

166
00:10:07,280 –> 00:10:09,480
mail via graph.

167
00:10:09,480 –> 00:10:14,120
With Defender XDR, the same incident flags the consent shows who granted it and offers

168
00:10:14,120 –> 00:10:21,120
one click revoc plus session kill, session dies, persistence dies, device isolates if needed.

169
00:10:21,120 –> 00:10:22,960
The ghost stops knocking.

170
00:10:22,960 –> 00:10:28,040
Email is the door sure, but without identity fusion and endpoint context, you’re guarding

171
00:10:28,040 –> 00:10:32,520
the foyer while the data walks out the loading dock.

172
00:10:32,520 –> 00:10:37,080
Defender XDR ties the handles together and locks the loading dock too.

173
00:10:37,080 –> 00:10:38,920
Blindspot 2.

174
00:10:38,920 –> 00:10:43,640
Identities AAD signals without endpoint and app context.

175
00:10:43,640 –> 00:10:47,480
Identities are the keys and attackers don’t brute force the lock anymore.

176
00:10:47,480 –> 00:10:50,480
They borrow the keys and make copies.

177
00:10:50,480 –> 00:10:57,480
Consent grants, token theft, MFA fatigue, quiet, durable, annoying to unwind if you only stare

178
00:10:57,480 –> 00:10:59,680
at Azure AAD risk.

179
00:10:59,680 –> 00:11:06,120
Here’s what most people miss as your AAD will dutifully flag risky sign-ins.

180
00:11:06,120 –> 00:11:12,680
Impossible travel, new device, anonymous IP, useful but alone its half a sentence.

181
00:11:12,680 –> 00:11:18,640
As the device healthy, did office spawn power shell, did a productivity app just get graph

182
00:11:18,640 –> 00:11:21,880
red, right from the same account?

183
00:11:21,880 –> 00:11:26,040
In a silo, you reset a password and pat yourself on the back.

184
00:11:26,040 –> 00:11:31,720
Except refresh tokens live, OAuth consent lives and the attacker lives right along with them.

185
00:11:31,720 –> 00:11:38,240
Okay, so basically, the simple version is identity without endpoint and app context lies

186
00:11:38,240 –> 00:11:39,560
to you.

187
00:11:39,560 –> 00:11:43,640
You see, user risk lowered, but you didn’t kill active sessions.

188
00:11:43,640 –> 00:11:48,200
You see MFA satisfied, but the token was stolen from a compromised device that still runs

189
00:11:48,200 –> 00:11:50,200
unsigned binaries at Logan.

190
00:11:50,200 –> 00:11:54,880
You see new app consented, but you don’t tie it to yesterday’s fish that dropped a malicious

191
00:11:54,880 –> 00:11:56,680
calm add-in.

192
00:11:56,680 –> 00:12:01,560
You get the picture, clean score, dirty reality.

193
00:12:01,560 –> 00:12:06,720
Defender XDR fuses the stream so the identity story finally has a plot.

194
00:12:06,720 –> 00:12:11,920
The risky sign in isn’t just a blip, it’s stitched to device posture, process lineage,

195
00:12:11,920 –> 00:12:14,360
and cloud app behavior.

196
00:12:14,360 –> 00:12:21,000
The same incident shows, suspicious token issuance, the endpoint that handled it, the process tree

197
00:12:21,000 –> 00:12:26,040
that harvested the browser cookie and the OAuth app that immediately started scraping

198
00:12:26,040 –> 00:12:31,920
SharePoint, one timeline, one user, one device, no guessing.

199
00:12:31,920 –> 00:12:37,160
This is the weird part, most orgs try to fix identity by tightening conditional access

200
00:12:37,160 –> 00:12:39,000
and calling it a day.

201
00:12:39,000 –> 00:12:42,480
Good, except it’s a gate, not a cleanup crew.

202
00:12:42,480 –> 00:12:48,560
If the tokens are already minted, policy changes are future-facing, the mess is present tense.

203
00:12:48,560 –> 00:12:55,080
Defender XDR closes the gap with automatic token revocation, session invalidation, and

204
00:12:55,080 –> 00:13:00,200
when policy allows, device isolation, all from the same incident pain.

205
00:13:00,200 –> 00:13:06,560
You don’t pray the sign in risk drops, you force it to by removing the attacker’s oxygen.

206
00:13:06,560 –> 00:13:12,480
Specific example, you get impossible travel at 0214 and a Windows device executes an unsigned

207
00:13:12,480 –> 00:13:17,120
binary at 0216 tied to the same user context.

208
00:13:17,120 –> 00:13:23,480
In a silo, two consoles, two teams endless slack with XDR, those correlate instantly.

209
00:13:23,480 –> 00:13:29,320
Auto IR can revoke the refreshed token, kill active sessions, mark the user risky, suggest

210
00:13:29,320 –> 00:13:33,040
conditional access hardening and contain the device pending review.

211
00:13:33,040 –> 00:13:38,680
The mailbox rules and OAuth consents tied to that account appear in the same view.

212
00:13:38,680 –> 00:13:43,000
You clear persistence in one pass, not three.

213
00:13:43,000 –> 00:13:48,400
Think of identity only tools like a security guard watching badge swipes on a screen.

214
00:13:48,400 –> 00:13:49,400
Useful.

215
00:13:49,400 –> 00:13:55,080
But if they never see the camera feed from the stairwell or the shipping dock logs, they’ll

216
00:13:55,080 –> 00:13:57,880
keep waving through a cloned badge.

217
00:13:57,880 –> 00:14:01,560
Defender XDR is the shared feed plus the intercom.

218
00:14:01,560 –> 00:14:06,440
You see the badge clone, the stairwell movement, and the door wedge on level 4, and you lock

219
00:14:06,440 –> 00:14:08,440
the doors in the right order.

220
00:14:08,440 –> 00:14:12,240
ROI shows up as fewer wild goose chases.

221
00:14:12,240 –> 00:14:18,800
A lone, risky sign in that doesn’t correlate to device anomalies stays low.

222
00:14:18,800 –> 00:14:21,400
Quietly, auto resolved.

223
00:14:21,400 –> 00:14:23,120
A real blast.

224
00:14:23,120 –> 00:14:29,600
Risky sign in plus browser token theft plus suspicious OAuth activity jumps to the top,

225
00:14:29,600 –> 00:14:32,400
already packaged with recommended actions.

226
00:14:32,400 –> 00:14:40,000
Fewer tickets, shorter timelines, clean evidence for audits without exporting half the tenant.

227
00:14:40,000 –> 00:14:43,440
You don’t solve identity by yelling at users about MFA.

228
00:14:43,440 –> 00:14:49,360
You solve it by collapsing identity, device, and app into one narrative and cutting power

229
00:14:49,360 –> 00:14:53,040
to the attacker’s session, not just changing the password.

230
00:14:53,040 –> 00:14:59,600
That’s the identity fusion defender XDR forces, and it stops the reinfection loop cold.

231
00:14:59,600 –> 00:15:01,240
Blind spot 3.

232
00:15:01,240 –> 00:15:02,240
Endpoints.

233
00:15:02,240 –> 00:15:06,320
EDR events without SAS and identity context.

234
00:15:06,320 –> 00:15:09,000
Endpoints are where the mess gets loud.

235
00:15:09,000 –> 00:15:10,000
Ransomware.

236
00:15:10,000 –> 00:15:11,320
LOL bins.

237
00:15:11,320 –> 00:15:14,240
Unsigned binaries doing yoga at startup.

238
00:15:14,240 –> 00:15:16,040
EDR is good at that noise.

239
00:15:16,040 –> 00:15:17,480
But here’s the catch.

240
00:15:17,480 –> 00:15:22,680
An endpoint can look clean, while the identity in SAS layer are filthy.

241
00:15:22,680 –> 00:15:24,400
You reinstall windows.

242
00:15:24,400 –> 00:15:27,920
The attacker keeps the refresh token in the OAuth foothold.

243
00:15:27,920 –> 00:15:30,200
You start the loop again next Tuesday.

244
00:15:30,200 –> 00:15:33,400
OK, so basically, processes don’t tell the whole story.

245
00:15:33,400 –> 00:15:39,640
EDR sees command prompt, spawning power shell, power shell touching LSS.

246
00:15:39,640 –> 00:15:42,080
Maybe a suspicious scheduled task.

247
00:15:42,080 –> 00:15:43,080
Useful.

248
00:15:43,080 –> 00:15:46,840
Except it doesn’t tell you the blast started with a fish, escalated through a consent grant

249
00:15:46,840 –> 00:15:50,000
and pivoted to SharePoint with a live browser token.

250
00:15:50,000 –> 00:15:53,640
Without SAS and identity context, you’re treating symptoms.

251
00:15:53,640 –> 00:15:55,080
The infection lives upstream.

252
00:15:55,080 –> 00:15:57,080
Here’s what most people miss.

253
00:15:57,080 –> 00:16:00,320
EDR alerts are often the middle of the movie.

254
00:16:00,320 –> 00:16:04,200
The opening scene is the user clicking “Except” on a two-friendly app.

255
00:16:04,200 –> 00:16:10,560
The ending is data walking out through cloud APIs, while your agent congratulates itself for

256
00:16:10,560 –> 00:16:11,920
killing a DLL.

257
00:16:11,920 –> 00:16:15,280
In a silo, you close the EDR ticket and celebrate.

258
00:16:15,280 –> 00:16:21,440
Meanwhile, the attacker reuses the token on a different machine, with the same identity

259
00:16:21,440 –> 00:16:24,040
and your logs look normal.

260
00:16:24,040 –> 00:16:27,040
Defender XDR drags the whole plot into one window.

261
00:16:27,040 –> 00:16:34,160
The unified incident graph ties process events to the user, the token, the mailbox rules,

262
00:16:34,160 –> 00:16:35,800
and the cloud sessions.

263
00:16:35,800 –> 00:16:41,560
That unsigned binary, you see it on the same timeline as the risky sign in the graph calls

264
00:16:41,560 –> 00:16:43,480
and the team’s file access.

265
00:16:43,480 –> 00:16:47,940
Now you know if the endpoint event is a fire or just smoke from a fire that already moved

266
00:16:47,940 –> 00:16:48,940
upstairs.

267
00:16:48,940 –> 00:16:50,840
Here’s the counter-intuitive part.

268
00:16:50,840 –> 00:16:54,120
Sometimes the right move isn’t to keep hammering the endpoint.

269
00:16:54,120 –> 00:16:58,400
It’s to cut the oxygen at identity and SAS first.

270
00:16:58,400 –> 00:17:04,840
With XDR, auto-IR can revoke refresh tokens, kill active sessions, and revoke a shady

271
00:17:04,840 –> 00:17:09,120
OAuth grant before you even finish reading the process tree.

272
00:17:09,120 –> 00:17:12,000
Then you contain the device, order matters.

273
00:17:12,000 –> 00:17:19,080
You stop the reinfection loop by breaking the session state, not just deleting the executable.

274
00:17:19,080 –> 00:17:20,880
Specific example you’ll recognize.

275
00:17:20,880 –> 00:17:25,560
EDR flags office spawning power shell with encoded commands.

276
00:17:25,560 –> 00:17:28,080
In isolation you block isolate scan.

277
00:17:28,080 –> 00:17:34,160
But in XDR, that event correlates with yesterday’s calendar helper 365 consent and a sudden spike

278
00:17:34,160 –> 00:17:37,720
in SharePoint download activity that’s not a drive-by macro.

279
00:17:37,720 –> 00:17:39,640
That’s an established persistence channel.

280
00:17:39,640 –> 00:17:45,560
From the same incident pane, you revoke consent, kill sessions, rollback mailbox rules, and

281
00:17:45,560 –> 00:17:48,200
quarantine the files that left the machine.

282
00:17:48,200 –> 00:17:52,200
The device goes into containment while identity gets cleaned.

283
00:17:52,200 –> 00:17:55,240
One pass, no swivel chair.

284
00:17:55,240 –> 00:17:59,280
Think of EDR only like listening to footsteps in one hallway.

285
00:17:59,280 –> 00:18:02,120
You hear noise, you chase it, you silence it.

286
00:18:02,120 –> 00:18:07,240
But the burglar is using the elevator and the roof access you never monitored.

287
00:18:07,240 –> 00:18:11,120
The XDR hands you the floor plan and the elevator controls.

288
00:18:11,120 –> 00:18:12,880
You don’t sprint room to room.

289
00:18:12,880 –> 00:18:16,480
You lock floors, stop the lift, then clear the hall.

290
00:18:16,480 –> 00:18:19,040
ROI shows up fast.

291
00:18:19,040 –> 00:18:24,480
Cross domain correlation means fewer critical device alerts that are actually benign without identity

292
00:18:24,480 –> 00:18:25,480
anomalies.

293
00:18:25,480 –> 00:18:30,880
Your cue shrinks because the platform dedupes the same root cause across 10 machines into

294
00:18:30,880 –> 00:18:32,440
one incident.

295
00:18:32,440 –> 00:18:37,120
And audits stop asking for screenshots from six consoles.

296
00:18:37,120 –> 00:18:43,120
The incident record already shows token revocations, session kills, device containment, and file

297
00:18:43,120 –> 00:18:46,160
governance in sequence.

298
00:18:46,160 –> 00:18:47,520
Clean endpoint.

299
00:18:47,520 –> 00:18:50,200
Dirty identity was yesterday’s headache.

300
00:18:50,200 –> 00:18:55,040
With Defender XDR you clean both in order so it stays clean.

301
00:18:55,040 –> 00:18:56,480
Endpoints aren’t islands.

302
00:18:56,480 –> 00:18:58,040
They’re bridges.

303
00:18:58,040 –> 00:19:02,160
Close the bridge at both ends and the attacker finally runs out of road.

304
00:19:02,160 –> 00:19:03,160
Blind spot for.

305
00:19:03,160 –> 00:19:08,280
Cloud apps, SAS and shadow it, without endpoint identity linkage.

306
00:19:08,280 –> 00:19:09,560
Now the highway.

307
00:19:09,560 –> 00:19:10,560
Cloud apps.

308
00:19:10,560 –> 00:19:16,240
SAS is where your data actually lives and where shadow IT multiplies like rabbits the

309
00:19:16,240 –> 00:19:19,720
minute finance discovers a freemium export button.

310
00:19:19,720 –> 00:19:25,560
You think you’re watching it because your TSB spits out oothle alerts and file shares.

311
00:19:25,560 –> 00:19:29,120
Accept it’s yelling into a void if it can’t touch identity and devices.

312
00:19:29,120 –> 00:19:33,320
That’s how X-Fill happens at noon while everyone’s staring at a green dashboard.

313
00:19:33,320 –> 00:19:35,000
Here’s what most people miss.

314
00:19:35,000 –> 00:19:39,120
Caspi alone sees the permission, not the person.

315
00:19:39,120 –> 00:19:44,640
It flags high risk oothle grant, but doesn’t know the token came from a machine with a sketchy

316
00:19:44,640 –> 00:19:49,360
browser extension and an unsigned binary at Logon.

317
00:19:49,360 –> 00:19:54,120
It sees unusual download rate from SharePoint, but can’t tell you it started five minutes

318
00:19:54,120 –> 00:19:58,040
after a fish and coincided with a refreshed token mint.

319
00:19:58,040 –> 00:20:03,400
You end up writing a stern email about responsible app usage while data walks out through graph

320
00:20:03,400 –> 00:20:05,480
politely with keys you issued.

321
00:20:05,480 –> 00:20:11,920
OK, so basically cloud telemetry without identity and endpoint context is a fun house mirror.

322
00:20:11,920 –> 00:20:17,080
The simple version is you need to tie app sessions to the user, the device posture and the

323
00:20:17,080 –> 00:20:20,200
identity session state in one incident.

324
00:20:20,200 –> 00:20:24,940
Defender XDR does that because defender for cloud apps lives inside the same incident

325
00:20:24,940 –> 00:20:26,420
graph.

326
00:20:26,420 –> 00:20:32,300
No-auth consent session governance file activity, they’re not separate alerts, they’re nodes

327
00:20:32,300 –> 00:20:37,220
on the same chain with the token, the sign in and the process tree.

328
00:20:37,220 –> 00:20:42,420
Here’s the weird part, the fastest win in cloud security isn’t another discovery scan.

329
00:20:42,420 –> 00:20:44,060
Its response in the right order.

330
00:20:44,060 –> 00:20:50,900
With Defender XDR, you can revoke the malicious app consent, kill active sessions, and if the

331
00:20:50,900 –> 00:20:55,460
source device is dirty, isolate it all from the incident pane.

332
00:20:55,460 –> 00:21:00,420
In quarantine or label the files that already left, you don’t draft a ticket for three teams.

333
00:21:00,420 –> 00:21:06,860
You pull the plug in one place, specific example, a time tracking app asks for offline access

334
00:21:06,860 –> 00:21:08,460
and files.

335
00:21:08,460 –> 00:21:10,220
Read right to all.

336
00:21:10,220 –> 00:21:17,100
In a silo, CASB flags it, someone promises to review and nothing changes.

337
00:21:17,100 –> 00:21:23,660
In XDR, that consent is linked to last night’s odd sign in and a device running an unsigned

338
00:21:23,660 –> 00:21:27,380
helper in the user profile.

339
00:21:27,380 –> 00:21:35,500
AutoIR suggests revoke consent, kill sessions, mark the user risky and contain the device.

340
00:21:35,500 –> 00:21:37,220
You click “Approve.”

341
00:21:37,220 –> 00:21:44,260
The falsehood closes before you debate the app’s business value, Shadow IT, same story.

342
00:21:44,260 –> 00:21:49,500
A user wires up a third party storage connector to export monthly reports.

343
00:21:49,500 –> 00:21:52,060
In isolation it’s productivity.

344
00:21:52,060 –> 00:21:58,100
In XDR, you see it correlates with abnormal download spikes and a browser token lifted

345
00:21:58,100 –> 00:22:00,420
from a machine with a bad extension.

346
00:22:00,420 –> 00:22:04,940
You revoke the connector’s token and force session controls and quarantine the exported

347
00:22:04,940 –> 00:22:06,700
files pending review.

348
00:22:06,700 –> 00:22:10,980
No swivel chair, no hunting for which admin portal owns the problem.

349
00:22:10,980 –> 00:22:16,340
Think of CASB only, like watching the loading dock with no badge list and no camera on the

350
00:22:16,340 –> 00:22:17,620
hallway.

351
00:22:17,620 –> 00:22:19,220
You see boxes leaving.

352
00:22:19,220 –> 00:22:21,620
You don’t know who carried them or if they had keys.

353
00:22:21,620 –> 00:22:26,420
Defender XDR gives you the badge list, the hallway camera and the lock controls.

354
00:22:26,420 –> 00:22:28,580
You don’t lock the theft, you stop it live.

355
00:22:28,580 –> 00:22:35,140
ROI shows up as fewer connectors, say no training and audits that stop chewing your weekends.

356
00:22:35,140 –> 00:22:40,660
One platform, one incident record, OAuth grants documented sessions killed, devices contained

357
00:22:40,660 –> 00:22:45,740
files governed with timestamps, toolsprongles downs, sodas your blood pressure.

358
00:22:45,740 –> 00:22:51,500
The ROI equation, consolidation beats complexity, proof and payback.

359
00:22:51,500 –> 00:22:54,980
Here’s the boring math that actually decides budgets.

360
00:22:54,980 –> 00:22:58,220
Toolsprong burns money in three places.

361
00:22:58,220 –> 00:23:00,820
People plumbing and panic.

362
00:23:00,820 –> 00:23:04,580
Defender XDR pays back by collapsing all three.

363
00:23:04,580 –> 00:23:08,180
People, one console, one incident story.

364
00:23:08,180 –> 00:23:11,900
Analysts stop copy pasting across vendors and start closing cases.

365
00:23:11,900 –> 00:23:14,820
Alert to dop and correlation, cut the cue.

366
00:23:14,820 –> 00:23:17,260
Auto IR handles the muscle memory.

367
00:23:17,260 –> 00:23:20,140
Lean teams suddenly look staffed.

368
00:23:20,140 –> 00:23:21,140
Plumbing.

369
00:23:21,140 –> 00:23:25,660
Native Microsoft integrations mean fewer connectors stitched together with three scripts

370
00:23:25,660 –> 00:23:26,860
and a prayer.

371
00:23:26,860 –> 00:23:28,180
Less maintenance.

372
00:23:28,180 –> 00:23:29,900
Faster onboarding.

373
00:23:29,900 –> 00:23:33,260
Training shrinks from six products to one stack.

374
00:23:33,260 –> 00:23:34,340
Panic.

375
00:23:34,340 –> 00:23:40,380
When an incident already shows the causal chain and offers actions, revoke tokens, kill sessions,

376
00:23:40,380 –> 00:23:43,940
isolate device, roll back mailbox rules.

377
00:23:43,940 –> 00:23:47,100
You shrink response time and blast radius.

378
00:23:47,100 –> 00:23:51,340
That’s real money.

379
00:23:51,340 –> 00:23:59,820
If you’re already paying for Microsoft 365 and Azure, you’re halfway there.

380
00:23:59,820 –> 00:24:05,820
Consolidation removes duplicate licenses, CM gymnastics for basics and the weekly scavenger

381
00:24:05,820 –> 00:24:08,180
hunt for audit artifacts.

382
00:24:08,180 –> 00:24:13,980
Typical payback lives in the 12 to 18 month window, not heroic, just cause and effect.

383
00:24:13,980 –> 00:24:20,420
The expense to saving switch flips on native cross domain incident correlation.

384
00:24:20,420 –> 00:24:23,980
One timeline replaces four tickets and three meetings.

385
00:24:23,980 –> 00:24:29,380
That’s the dividend, handling objections without the drama, counter arguments resolved.

386
00:24:29,380 –> 00:24:30,380
Vendor lock in.

387
00:24:30,380 –> 00:24:35,660
Sure, you’re already locked into M365 for identities, mail and files.

388
00:24:35,660 –> 00:24:37,660
Native beats, glue code.

389
00:24:37,660 –> 00:24:42,500
XDR still feeds Sentinel or Splunk for compliance and forensics.

390
00:24:42,500 –> 00:24:43,500
We have a seam.

391
00:24:43,500 –> 00:24:44,500
Great.

392
00:24:44,500 –> 00:24:45,500
Keep it.

393
00:24:45,500 –> 00:24:48,660
Let XDR do real time detection and response.

394
00:24:48,660 –> 00:24:52,900
Stop forcing seam to impersonate an EDR plus KSP plus SOAR.

395
00:24:52,900 –> 00:24:56,820
To complex, complexity is the silos.

396
00:24:56,820 –> 00:25:00,540
Pre-built connectors, one console, Auto IR with approvals.

397
00:25:00,540 –> 00:25:02,980
Fewer moving parts.

398
00:25:02,980 –> 00:25:05,220
We’ll lose control.

399
00:25:05,220 –> 00:25:07,260
Automation is policy bound.

400
00:25:07,260 –> 00:25:11,220
You choose what auto executes and what asks first.

401
00:25:11,220 –> 00:25:13,220
We can’t afford it.

402
00:25:13,220 –> 00:25:14,500
You’re already paying.

403
00:25:14,500 –> 00:25:19,980
Alert fatigue, staffing churn, breach cleanup, audit overtime.

404
00:25:19,980 –> 00:25:22,980
Consolidation trims the mess and the bill.

405
00:25:22,980 –> 00:25:28,260
The mandatory correction, hybrid security fails when your tools don’t talk.

406
00:25:28,260 –> 00:25:34,140
Defender XDR forces one incident language with one timeline and cross domain actions.

407
00:25:34,140 –> 00:25:35,140
That’s the fix.

408
00:25:35,140 –> 00:25:39,660
If you want compliance depth without giving up real time speed, watch the breakdown on

409
00:25:39,660 –> 00:25:42,780
wiring defender XDR into your seam.

410
00:25:42,780 –> 00:25:46,020
Sentinel, Splunk, whatever you already run.

411
00:25:46,020 –> 00:25:51,340
Subscribe so you don’t get stuck rebuilding the same wet cardboard stack next quarter.

412
00:25:51,340 –> 00:25:52,860
Pick structure over entropy now.
