1
00:00:00,000 --> 00:00:02,440
Antivirus used to be enough, but it isn't anymore.
2
00:00:02,440 --> 00:00:03,800
You probably remember the old days.
3
00:00:03,800 --> 00:00:07,120
In Stolar program, it scans your files and you're protected.
4
00:00:07,120 --> 00:00:08,360
Simple, that world is gone.
5
00:00:08,360 --> 00:00:11,240
Today, Ranzwer encounters are up 275%,
6
00:00:11,240 --> 00:00:14,720
and 68% of all cyber attacks now target the devices
7
00:00:14,720 --> 00:00:17,440
sitting on your desk, in your bag, or on your kitchen table.
8
00:00:17,440 --> 00:00:19,440
So what is Microsoft Defender for Endpoint?
9
00:00:19,440 --> 00:00:21,360
And why is every business talking about it?
10
00:00:21,360 --> 00:00:22,880
By the end of this episode, you'll understand
11
00:00:22,880 --> 00:00:24,440
what Endpoint security actually means.
12
00:00:24,440 --> 00:00:25,960
How Defender for Endpoint is different
13
00:00:25,960 --> 00:00:28,600
from basic antivirus and why it matters for your company.
14
00:00:28,600 --> 00:00:31,160
We'll break it down into building blocks, what it protects,
15
00:00:31,160 --> 00:00:33,760
how it protects it, and how it all fits together.
16
00:00:33,760 --> 00:00:35,560
So let's start with the basics.
17
00:00:35,560 --> 00:00:37,320
What is Endpoint security?
18
00:00:37,320 --> 00:00:38,680
First, what is an endpoint?
19
00:00:38,680 --> 00:00:41,000
It's any device that connects to your company's network,
20
00:00:41,000 --> 00:00:43,720
laptops, desktops, phones, tablets, servers,
21
00:00:43,720 --> 00:00:45,320
anything with an internet connection.
22
00:00:45,320 --> 00:00:48,800
In the office building analogy, if Microsoft 365 is your building,
23
00:00:48,800 --> 00:00:50,320
endpoints are the doors and windows.
24
00:00:50,320 --> 00:00:52,080
Every single one is a potential way in.
25
00:00:52,080 --> 00:00:54,720
Now, the old way of protecting these devices was simple.
26
00:00:54,720 --> 00:00:56,560
You installed antivirus on each machine
27
00:00:56,560 --> 00:00:57,680
and it ran on its own.
28
00:00:57,680 --> 00:00:59,880
It checked files against a list of known threats.
29
00:00:59,880 --> 00:01:01,720
And if something matched, it blocked it.
30
00:01:01,720 --> 00:01:02,640
That worked for a while.
31
00:01:02,640 --> 00:01:04,880
But attackers don't break in through the front door anymore.
32
00:01:04,880 --> 00:01:07,120
They don't use the same tools twice, they evolve.
33
00:01:07,120 --> 00:01:09,160
So Endpoint security today means something different.
34
00:01:09,160 --> 00:01:10,960
It's about protecting every device,
35
00:01:10,960 --> 00:01:12,880
not just the ones you think are important.
36
00:01:12,880 --> 00:01:15,880
You need to watch for behavior, not just look for known bad files.
37
00:01:15,880 --> 00:01:18,240
And you need to build a security system around every device,
38
00:01:18,240 --> 00:01:20,000
not just install one piece of software.
39
00:01:20,000 --> 00:01:22,000
Here's the thing though, most people still think
40
00:01:22,000 --> 00:01:24,000
of endpoint security as antivirus.
41
00:01:24,000 --> 00:01:25,760
And that's where the problem starts.
42
00:01:25,760 --> 00:01:27,760
Why traditional antivirus isn't enough?
43
00:01:27,760 --> 00:01:30,200
Let's talk about what traditional antivirus actually does.
44
00:01:30,200 --> 00:01:33,080
It scans files, checks them against a list of known threats,
45
00:01:33,080 --> 00:01:35,920
signatures they're called, and blocks anything that matches.
46
00:01:35,920 --> 00:01:38,840
It's like having a security guard who only checks a wanted poster.
47
00:01:38,840 --> 00:01:41,200
If the thief isn't on the poster, they walk right past.
48
00:01:41,200 --> 00:01:42,680
And that's the core limitation.
49
00:01:42,680 --> 00:01:45,880
Signature-based detection only catches what's already been seen.
50
00:01:45,880 --> 00:01:47,720
Modern attacks are adaptive, targeted,
51
00:01:47,720 --> 00:01:50,040
and often use brand new or custom malware.
52
00:01:50,040 --> 00:01:51,960
Attackers don't use the same tools twice.
53
00:01:51,960 --> 00:01:52,560
They evolve.
54
00:01:52,560 --> 00:01:54,240
Traditional antivirus can't keep up.
55
00:01:54,240 --> 00:01:55,560
The numbers back this up.
56
00:01:55,560 --> 00:01:57,400
AI-powered endpoint protection now achieves
57
00:01:57,400 --> 00:01:59,600
an 89% automatic detection rate.
58
00:01:59,600 --> 00:02:00,640
Traditional antivirus?
59
00:02:00,640 --> 00:02:01,880
Just 42%.
60
00:02:01,880 --> 00:02:02,960
That's a massive gap.
61
00:02:02,960 --> 00:02:05,360
And it's not just about missing the initial attack.
62
00:02:05,360 --> 00:02:07,160
Traditional antivirus has no visibility
63
00:02:07,160 --> 00:02:08,920
into what happens after a breach starts.
64
00:02:08,920 --> 00:02:11,160
An attacker might already be inside your network,
65
00:02:11,160 --> 00:02:12,720
moving from machine to machine.
66
00:02:12,720 --> 00:02:14,240
And traditional AV wouldn't know.
67
00:02:14,240 --> 00:02:15,520
It has no eyes on behavior.
68
00:02:15,520 --> 00:02:17,920
So you need something that watches for unusual behavior,
69
00:02:17,920 --> 00:02:19,680
not just known bad files.
70
00:02:19,680 --> 00:02:22,040
You need something that can see the attacker moving,
71
00:02:22,040 --> 00:02:24,600
even if the file they're using has never been seen before.
72
00:02:24,600 --> 00:02:26,720
That's where Defender for Endpoint comes in.
73
00:02:26,720 --> 00:02:28,320
What is Defender for Endpoint?
74
00:02:28,320 --> 00:02:30,840
So what does Defender for Endpoint actually do?
75
00:02:30,840 --> 00:02:31,680
Let's look at it.
76
00:02:31,680 --> 00:02:33,800
Microsoft Defender for Endpoint is a cloud-powered
77
00:02:33,800 --> 00:02:35,360
endpoint security platform.
78
00:02:35,360 --> 00:02:36,800
That's the official definition.
79
00:02:36,800 --> 00:02:38,720
But here's what that means in plain English.
80
00:02:38,720 --> 00:02:39,960
It's not a single product.
81
00:02:39,960 --> 00:02:41,360
It's a collection of capabilities
82
00:02:41,360 --> 00:02:43,520
that work together to protect your devices.
83
00:02:43,520 --> 00:02:46,160
Think of it as three main pillars, prevention, detection,
84
00:02:46,160 --> 00:02:46,960
and response.
85
00:02:46,960 --> 00:02:48,960
Prevention stops attacks before they happen.
86
00:02:48,960 --> 00:02:51,080
Detection finds the ones that get through anyway.
87
00:02:51,080 --> 00:02:52,680
And response automatically contains
88
00:02:52,680 --> 00:02:53,760
and investigates them.
89
00:02:53,760 --> 00:02:56,000
Traditional antivirus is a lock on the door.
90
00:02:56,000 --> 00:02:57,880
Defender for Endpoint is a security system
91
00:02:57,880 --> 00:03:00,560
with cameras, motion sensors, and a team watching the monitors.
92
00:03:00,560 --> 00:03:02,600
Now one thing that trips people up is the naming.
93
00:03:02,600 --> 00:03:04,480
Defender for Endpoint isn't just for Windows.
94
00:03:04,480 --> 00:03:07,600
It protects devices across Windows, Mac OS, Linux, Android,
95
00:03:07,600 --> 00:03:08,720
and iOS.
96
00:03:08,720 --> 00:03:10,480
Whether your team is in the office at home
97
00:03:10,480 --> 00:03:13,240
or working from a coffee shop, the same protection follows them.
98
00:03:13,240 --> 00:03:14,400
There are two plans.
99
00:03:14,400 --> 00:03:16,680
Plan one gives you basic protection.
100
00:03:16,680 --> 00:03:19,400
Next, Gen Antivirus, attack surface reduction,
101
00:03:19,400 --> 00:03:20,880
and some basic detection.
102
00:03:20,880 --> 00:03:22,880
Plan two is where the real power lives.
103
00:03:22,880 --> 00:03:25,400
That's the full EDR suite with advanced hunting,
104
00:03:25,400 --> 00:03:28,640
automated investigation, and six months of telemetry retention.
105
00:03:28,640 --> 00:03:30,320
And here's the part most people miss.
106
00:03:30,320 --> 00:03:33,200
Plan two is included in Microsoft 365 E5.
107
00:03:33,200 --> 00:03:35,160
If you already have E5, you already have this.
108
00:03:35,160 --> 00:03:36,200
You just need to turn it on.
109
00:03:36,200 --> 00:03:37,560
The key differentiator is this.
110
00:03:37,560 --> 00:03:38,640
It's not just antivirus.
111
00:03:38,640 --> 00:03:41,240
It's an Endpoint detection and response platform.
112
00:03:41,240 --> 00:03:43,880
And that changes everything about how you think about security.
113
00:03:43,880 --> 00:03:45,560
Let's break down what that actually means,
114
00:03:45,560 --> 00:03:47,440
starting with the first layer.
115
00:03:47,440 --> 00:03:48,960
Next, Generation Protection.
116
00:03:48,960 --> 00:03:50,320
This is the prevention layer.
117
00:03:50,320 --> 00:03:52,560
It's what most people think of as antivirus.
118
00:03:52,560 --> 00:03:54,040
But it's actually much smarter than that
119
00:03:54,040 --> 00:03:56,240
because it uses machine learning and behavior analysis
120
00:03:56,240 --> 00:03:58,280
instead of just looking for known viruses.
121
00:03:58,280 --> 00:04:00,560
Next, Generation Protection uses machine learning,
122
00:04:00,560 --> 00:04:03,320
behavior analysis, and cloud-based threat intelligence
123
00:04:03,320 --> 00:04:04,880
to detect suspicious behavior,
124
00:04:04,880 --> 00:04:07,240
rather than just flagging known bad files.
125
00:04:07,240 --> 00:04:09,680
So if a script tries to modify system files,
126
00:04:09,680 --> 00:04:11,840
even if it's not a known virus, the system catches it
127
00:04:11,840 --> 00:04:13,280
because the behavior is unusual.
128
00:04:13,280 --> 00:04:15,800
It's like a security guard who notices someone acting nervous
129
00:04:15,800 --> 00:04:17,680
even if they're not on the wanted list.
130
00:04:17,680 --> 00:04:20,440
The guard doesn't need to recognize the person just the behavior.
131
00:04:20,440 --> 00:04:22,720
Part of this is attack surface reduction.
132
00:04:22,720 --> 00:04:25,160
Tiny rules that block common attack techniques.
133
00:04:25,160 --> 00:04:27,080
For example, blocking macros from office files
134
00:04:27,080 --> 00:04:28,400
downloaded from the internet
135
00:04:28,400 --> 00:04:30,920
or preventing USB drives from running scripts.
136
00:04:30,920 --> 00:04:32,640
These are small things, but they shut down
137
00:04:32,640 --> 00:04:34,280
the method attackers use most.
138
00:04:34,280 --> 00:04:36,760
In the 2024 Miterat tank evaluation,
139
00:04:36,760 --> 00:04:39,480
Defender for Endpoint delivered 100% protection.
140
00:04:39,480 --> 00:04:41,160
That's not a marketing claim.
141
00:04:41,160 --> 00:04:44,160
It's an independent test against real world attack scenarios.
142
00:04:44,160 --> 00:04:46,120
This layer runs automatically.
143
00:04:46,120 --> 00:04:47,280
You don't have to think about it.
144
00:04:47,280 --> 00:04:49,640
No manual scanning, no scheduled updates.
145
00:04:49,640 --> 00:04:51,040
It just works in the background,
146
00:04:51,040 --> 00:04:52,480
but prevention isn't perfect.
147
00:04:52,480 --> 00:04:54,080
No system catches everything.
148
00:04:54,080 --> 00:04:56,080
That's where the next layer comes in.
149
00:04:56,080 --> 00:04:58,560
Endpoint detection and response, EDR.
150
00:04:58,560 --> 00:05:01,480
So prevention catches a lot, but it doesn't catch everything.
151
00:05:01,480 --> 00:05:02,640
That's where EDR comes in.
152
00:05:02,640 --> 00:05:05,160
EDR stands for endpoint detection and response
153
00:05:05,160 --> 00:05:07,320
and it's what happens after an attack gets through.
154
00:05:07,320 --> 00:05:08,160
Think of it this way.
155
00:05:08,160 --> 00:05:10,040
Prevention is the lock on your front door.
156
00:05:10,040 --> 00:05:12,040
And EDR is the motion sensor in your hallway
157
00:05:12,040 --> 00:05:14,520
that alerts you when someone's already inside.
158
00:05:14,520 --> 00:05:16,240
Every device running Defender for Endpoint
159
00:05:16,240 --> 00:05:18,640
sends telemetry data to the cloud constantly.
160
00:05:18,640 --> 00:05:21,040
File changes, process launches, network connections,
161
00:05:21,040 --> 00:05:22,280
registry edits.
162
00:05:22,280 --> 00:05:23,960
The sensors are always watching.
163
00:05:23,960 --> 00:05:25,840
And this data gets analyzed by AI
164
00:05:25,840 --> 00:05:27,280
to detect suspicious patterns.
165
00:05:27,280 --> 00:05:29,000
It's like having cameras in every room
166
00:05:29,000 --> 00:05:31,080
with an AI that watches all the feeds at once
167
00:05:31,080 --> 00:05:32,600
and flags anything unusual.
168
00:05:32,600 --> 00:05:34,200
Security teams can actually search
169
00:05:34,200 --> 00:05:36,560
across all their devices for signs of compromise.
170
00:05:36,560 --> 00:05:37,920
This is called threat hunting.
171
00:05:37,920 --> 00:05:39,800
You can ask a question like, has anyone run
172
00:05:39,800 --> 00:05:41,120
the suspicious command?
173
00:05:41,120 --> 00:05:43,440
And get answers in seconds, not hours.
174
00:05:43,440 --> 00:05:45,680
And because telemetry is stored for up to six months
175
00:05:45,680 --> 00:05:47,440
with Plan 2, you can investigate attacks
176
00:05:47,440 --> 00:05:48,480
that happen months ago.
177
00:05:48,480 --> 00:05:51,080
An attack that came in through a fishing email back in January,
178
00:05:51,080 --> 00:05:52,560
you can still trace it in June.
179
00:05:52,560 --> 00:05:54,960
That lets you map out exactly how an attacker got in
180
00:05:54,960 --> 00:05:56,160
and what they touched.
181
00:05:56,160 --> 00:05:59,280
A user clicks a fishing link, but nothing happens immediately.
182
00:05:59,280 --> 00:06:01,760
No malware drops, no files getting crypted.
183
00:06:01,760 --> 00:06:03,480
Everything looks normal.
184
00:06:03,480 --> 00:06:05,520
Weeks later, the attacker tries to move
185
00:06:05,520 --> 00:06:06,840
literally across the network.
186
00:06:06,840 --> 00:06:08,560
That's when EDR catches it.
187
00:06:08,560 --> 00:06:10,120
The initial infection wasn't obvious,
188
00:06:10,120 --> 00:06:12,480
but the behavior after the attacker trying to hop
189
00:06:12,480 --> 00:06:14,960
from one machine to another is what EDR finds.
190
00:06:14,960 --> 00:06:16,600
Instead of getting 50 separate alerts,
191
00:06:16,600 --> 00:06:17,760
you get one incident view.
192
00:06:17,760 --> 00:06:19,640
All the alerts from multiple devices
193
00:06:19,640 --> 00:06:21,840
get grouped together into a single story.
194
00:06:21,840 --> 00:06:24,960
The attacker's whole journey mapped out from start to finish.
195
00:06:24,960 --> 00:06:27,240
Instead of 50 puzzle pieces scattered across your screen,
196
00:06:27,240 --> 00:06:28,560
you get the full picture.
197
00:06:28,560 --> 00:06:31,240
But finding an attack is only half the battle.
198
00:06:31,240 --> 00:06:32,920
You also need to understand your weaknesses
199
00:06:32,920 --> 00:06:35,680
before an attacker finds them.
200
00:06:35,680 --> 00:06:38,080
Vulnerability, management, and threat analytics.
201
00:06:38,080 --> 00:06:40,160
So we've talked about prevention and detection,
202
00:06:40,160 --> 00:06:42,160
but there's another layer that traditional antivirus
203
00:06:42,160 --> 00:06:43,080
never touched.
204
00:06:43,080 --> 00:06:44,800
This is the Know Your Weaknesses layer.
205
00:06:44,800 --> 00:06:45,640
And it's a big deal.
206
00:06:45,640 --> 00:06:46,960
Defender for endpoint constantly
207
00:06:46,960 --> 00:06:49,120
scans your devices for missing patches,
208
00:06:49,120 --> 00:06:51,200
weak configurations, and exposed settings.
209
00:06:51,200 --> 00:06:52,200
It doesn't wait for an attack.
210
00:06:52,200 --> 00:06:54,040
It tells you upfront, hey, these 50 devices
211
00:06:54,040 --> 00:06:55,840
are missing a critical Windows update.
212
00:06:55,840 --> 00:06:56,880
Fix them first.
213
00:06:56,880 --> 00:06:57,760
That's proactive.
214
00:06:57,760 --> 00:06:59,760
Old-school antivirus would just sit there.
215
00:06:59,760 --> 00:07:00,640
But here's the thing.
216
00:07:00,640 --> 00:07:03,000
Not all vulnerabilities are created equal.
217
00:07:03,000 --> 00:07:04,720
Some are critical, some are minor.
218
00:07:04,720 --> 00:07:07,880
And some are actively being exploited by attackers right now
219
00:07:07,880 --> 00:07:08,840
out in the wild.
220
00:07:08,840 --> 00:07:11,640
Defender uses something called exploit prediction data,
221
00:07:11,640 --> 00:07:14,520
EPSS for short, to figure out what's most likely to be hit.
222
00:07:14,520 --> 00:07:15,880
You don't have to fix everything.
223
00:07:15,880 --> 00:07:17,920
You fix the things that actually matter.
224
00:07:17,920 --> 00:07:19,120
That's the smart approach.
225
00:07:19,120 --> 00:07:21,920
The system also does something called attack path modeling.
226
00:07:21,920 --> 00:07:23,440
Imagine a map of your office building
227
00:07:23,440 --> 00:07:25,840
showing every possible route a burglar could take.
228
00:07:25,840 --> 00:07:27,800
Maybe one device has an outdated browser.
229
00:07:27,800 --> 00:07:29,200
Another has a weak password.
230
00:07:29,200 --> 00:07:30,600
Separately, those are minor issues.
231
00:07:30,600 --> 00:07:32,880
But chain together, they become a clear path
232
00:07:32,880 --> 00:07:34,320
to your most sensitive files.
233
00:07:34,320 --> 00:07:35,440
That's exactly what this does.
234
00:07:35,440 --> 00:07:36,960
It shows how an attacker could connect
235
00:07:36,960 --> 00:07:39,280
the dots from one vulnerability to the next.
236
00:07:39,280 --> 00:07:40,920
So instead of guessing what to patch next,
237
00:07:40,920 --> 00:07:43,440
your security team gets a clear prioritized list.
238
00:07:43,440 --> 00:07:44,720
No guesswork, no panic.
239
00:07:44,720 --> 00:07:47,000
Just a road map, you know exactly what to fix first.
240
00:07:47,000 --> 00:07:49,320
But what happens when an attack is already in progress?
241
00:07:49,320 --> 00:07:51,080
That's where automation kicks in.
242
00:07:51,080 --> 00:07:53,320
Automated investigation and attack disruption.
243
00:07:53,320 --> 00:07:54,800
So prevention blocks what it can.
244
00:07:54,800 --> 00:07:56,240
Detection finds what gets through.
245
00:07:56,240 --> 00:07:58,400
But what about when an attack is happening right now?
246
00:07:58,400 --> 00:08:00,560
In real time, that's the response layer.
247
00:08:00,560 --> 00:08:02,600
And honestly, this might be the most impressive part
248
00:08:02,600 --> 00:08:03,440
of the whole system.
249
00:08:03,440 --> 00:08:05,280
When Defender for Endpoint detects a threat,
250
00:08:05,280 --> 00:08:06,800
it doesn't just fire off an alert
251
00:08:06,800 --> 00:08:08,040
and hope someone sees it.
252
00:08:08,040 --> 00:08:08,840
It acts.
253
00:08:08,840 --> 00:08:10,480
The system runs automated playbooks
254
00:08:10,480 --> 00:08:12,240
to figure out if the alert is real.
255
00:08:12,240 --> 00:08:15,360
It asks questions like, is this file actually malicious?
256
00:08:15,360 --> 00:08:16,440
Is it on other devices?
257
00:08:16,440 --> 00:08:18,320
Has it connected to known bad servers?
258
00:08:18,320 --> 00:08:20,680
It does all of this in seconds, not hours.
259
00:08:20,680 --> 00:08:22,840
Think about how long it would take a human to do that.
260
00:08:22,840 --> 00:08:25,480
If the threat is confirmed, the system takes action.
261
00:08:25,480 --> 00:08:27,280
It isolates the device from the network.
262
00:08:27,280 --> 00:08:29,000
Blocks the file, removes the threat.
263
00:08:29,000 --> 00:08:30,680
The machine gets cut off before the attacker
264
00:08:30,680 --> 00:08:32,000
can spread to anything else.
265
00:08:32,000 --> 00:08:33,400
No human has to click a button.
266
00:08:33,400 --> 00:08:35,800
The system just does it automatically.
267
00:08:35,800 --> 00:08:37,400
But there's an even more advanced version
268
00:08:37,400 --> 00:08:39,480
called automatic attack disruption.
269
00:08:39,480 --> 00:08:41,200
And this is where things get really interesting.
270
00:08:41,200 --> 00:08:44,320
Attack disruption uses AI to predict what the attacker will do
271
00:08:44,320 --> 00:08:46,400
next and blocks it before they can try.
272
00:08:46,400 --> 00:08:48,080
It's not reacting to what already happened.
273
00:08:48,080 --> 00:08:49,560
It's anticipating the next move.
274
00:08:49,560 --> 00:08:51,200
That's a whole different level.
275
00:08:51,200 --> 00:08:53,720
Here's a real example from Microsoft's own research.
276
00:08:53,720 --> 00:08:56,360
Imagine an attacker gets access to your domain controller.
277
00:08:56,360 --> 00:08:58,600
That's the server that handles user authentication
278
00:08:58,600 --> 00:09:00,280
across your entire organization.
279
00:09:00,280 --> 00:09:02,000
In most security setups, you can't just
280
00:09:02,000 --> 00:09:03,400
shut down the domain controller.
281
00:09:03,400 --> 00:09:04,480
It's too critical.
282
00:09:04,480 --> 00:09:06,960
So other solutions would isolate the compromised machines
283
00:09:06,960 --> 00:09:09,960
around it, but leave the domain controller itself exposed.
284
00:09:09,960 --> 00:09:11,400
The attacker can still pivot.
285
00:09:11,400 --> 00:09:13,440
Defender for endpoint handles this differently.
286
00:09:13,440 --> 00:09:15,360
It detects that a specific IP address
287
00:09:15,360 --> 00:09:17,920
connected to the domain controller is malicious.
288
00:09:17,920 --> 00:09:19,160
So it blocks that IP.
289
00:09:19,160 --> 00:09:19,960
But here's the key.
290
00:09:19,960 --> 00:09:21,880
It doesn't shut down the domain controller.
291
00:09:21,880 --> 00:09:24,640
Legitimate users keep authenticating normally.
292
00:09:24,640 --> 00:09:27,000
The attacker is blocked, but your business keeps running.
293
00:09:27,000 --> 00:09:28,760
The system can distinguish malicious behavior
294
00:09:28,760 --> 00:09:29,640
from benign behavior.
295
00:09:29,640 --> 00:09:30,800
That's a huge deal.
296
00:09:30,800 --> 00:09:31,760
And speed matters.
297
00:09:31,760 --> 00:09:34,840
Microsoft says automatic attack disruption stops ransomware
298
00:09:34,840 --> 00:09:36,880
attacks in an average of just three minutes.
299
00:09:36,880 --> 00:09:37,760
Three minutes.
300
00:09:37,760 --> 00:09:39,920
The attacker doesn't have time to encrypt anything.
301
00:09:39,920 --> 00:09:41,720
The system moves faster than they do.
302
00:09:41,720 --> 00:09:43,920
And this isn't some theoretical capability.
303
00:09:43,920 --> 00:09:46,280
Microsoft disrupts about 16,000 such incidents
304
00:09:46,280 --> 00:09:47,240
every single month.
305
00:09:47,240 --> 00:09:48,520
That's happening right now.
306
00:09:48,520 --> 00:09:49,400
Think of it this way.
307
00:09:49,400 --> 00:09:51,440
Traditional antivirus is a lock on the door.
308
00:09:51,440 --> 00:09:53,600
Defender for endpoint is a security guard who
309
00:09:53,600 --> 00:09:55,320
sees someone trying to pick the lock and calls
310
00:09:55,320 --> 00:09:57,080
the police before they get inside.
311
00:09:57,080 --> 00:09:58,600
And then stays on watch to make sure they don't
312
00:09:58,600 --> 00:09:59,360
try a different door.
313
00:09:59,360 --> 00:10:00,520
That's the difference.
314
00:10:00,520 --> 00:10:03,440
But all of this works better because it's not standing alone.
315
00:10:03,440 --> 00:10:05,120
It's part of a bigger platform.
316
00:10:05,120 --> 00:10:07,920
How Defender for endpoint fits into Microsoft 365?
317
00:10:07,920 --> 00:10:10,120
Here's the thing that makes Defender for endpoint different
318
00:10:10,120 --> 00:10:11,680
from a standalone security product.
319
00:10:11,680 --> 00:10:13,240
It doesn't live in isolation.
320
00:10:13,240 --> 00:10:15,840
It's part of the Microsoft Defender XDR platform.
321
00:10:15,840 --> 00:10:18,960
And XDR stands for extended detection and response.
322
00:10:18,960 --> 00:10:21,080
What that means in plain English is that it pulls data
323
00:10:21,080 --> 00:10:23,440
from multiple sources, not just endpoints.
324
00:10:23,440 --> 00:10:25,520
So it's watching your devices, but it's also
325
00:10:25,520 --> 00:10:28,480
watching identities, email, cloud apps, and data.
326
00:10:28,480 --> 00:10:30,880
All those feeds come together into a single view.
327
00:10:30,880 --> 00:10:33,360
Let me give you a concrete example of why this matters.
328
00:10:33,360 --> 00:10:35,880
Imagine a phishing email arrives in someone's inbox.
329
00:10:35,880 --> 00:10:38,520
Defender for Office 365 flags it as suspicious,
330
00:10:38,520 --> 00:10:41,000
but the user clicks the link anyway.
331
00:10:41,000 --> 00:10:42,880
Defender for endpoint sees the malware
332
00:10:42,880 --> 00:10:44,320
trying to run on the device.
333
00:10:44,320 --> 00:10:46,880
Defender for identity watches for credential theft.
334
00:10:46,880 --> 00:10:48,600
Now, instead of three different alerts
335
00:10:48,600 --> 00:10:50,400
in three different portals, all of these
336
00:10:50,400 --> 00:10:52,240
get correlated into a single incident.
337
00:10:52,240 --> 00:10:53,240
You get one story.
338
00:10:53,240 --> 00:10:54,960
The attack is full journey from the email
339
00:10:54,960 --> 00:10:57,880
to the endpoint to the stolen credentials, all in one place.
340
00:10:57,880 --> 00:10:59,320
That's the power of XDR.
341
00:10:59,320 --> 00:11:00,840
Silent alerts from different products
342
00:11:00,840 --> 00:11:02,360
become one complete picture.
343
00:11:02,360 --> 00:11:04,840
You see the full story, not just fragments.
344
00:11:04,840 --> 00:11:06,160
And the integration goes deeper.
345
00:11:06,160 --> 00:11:08,520
If your organization uses Microsoft Sentinel,
346
00:11:08,520 --> 00:11:11,360
Defender for endpoint feeds directly into it.
347
00:11:11,360 --> 00:11:13,480
If you use Intune for device management,
348
00:11:13,480 --> 00:11:16,400
Defender enforces security policies through it.
349
00:11:16,400 --> 00:11:18,680
The same sensor handles endpoint protection, identity
350
00:11:18,680 --> 00:11:20,160
protection, and data loss prevention.
351
00:11:20,160 --> 00:11:22,880
One agent, one portal, one view of your security.
352
00:11:22,880 --> 00:11:24,880
If you're already using Microsoft 365,
353
00:11:24,880 --> 00:11:26,600
you're not starting from scratch.
354
00:11:26,600 --> 00:11:27,920
The pieces are already there.
355
00:11:27,920 --> 00:11:29,280
You just need to connect them.
356
00:11:29,280 --> 00:11:31,200
And here's the part that surprises most people.
357
00:11:31,200 --> 00:11:33,680
Defender for endpoint plan two is included
358
00:11:33,680 --> 00:11:35,400
in Microsoft 365 E5.
359
00:11:35,400 --> 00:11:37,560
If you have E5, this is already paid for,
360
00:11:37,560 --> 00:11:38,920
you're leaving protection on the table
361
00:11:38,920 --> 00:11:40,040
if you don't turn it on.
362
00:11:40,040 --> 00:11:41,360
So that's the system.
363
00:11:41,360 --> 00:11:43,360
Prevention, detection, response,
364
00:11:43,360 --> 00:11:45,720
all connected across the Microsoft ecosystem.
365
00:11:45,720 --> 00:11:47,680
But how do you actually get started?
366
00:11:47,680 --> 00:11:48,760
How to get started?
367
00:11:48,760 --> 00:11:51,000
You've heard the pitch and the technology sounds great.
368
00:11:51,000 --> 00:11:52,960
But how do you actually get this thing running?
369
00:11:52,960 --> 00:11:53,880
Let me walk you through it.
370
00:11:53,880 --> 00:11:55,720
First step, check your license.
371
00:11:55,720 --> 00:11:58,720
If you have Microsoft 365 E5 or business premium,
372
00:11:58,720 --> 00:12:00,800
you already have access to Defender for endpoint.
373
00:12:00,800 --> 00:12:01,720
It's already paid for.
374
00:12:01,720 --> 00:12:03,080
You just need to turn it on.
375
00:12:03,080 --> 00:12:06,000
That's the single biggest unlock most organizations miss.
376
00:12:06,000 --> 00:12:07,720
Second step, connect the portals.
377
00:12:07,720 --> 00:12:10,640
You need to enable the link between Intune and Defender
378
00:12:10,640 --> 00:12:11,960
so they can share data.
379
00:12:11,960 --> 00:12:13,160
Head over to security.
380
00:12:13,160 --> 00:12:16,480
Microsoft.com, navigate to settings, find the endpoint section,
381
00:12:16,480 --> 00:12:18,400
and look for the Microsoft Intune connection.
382
00:12:18,400 --> 00:12:19,360
Flip that switch on.
383
00:12:19,360 --> 00:12:22,680
Then go to Intune, Microsoft.com, find endpoint security,
384
00:12:22,680 --> 00:12:24,560
and enable the same connection on that side.
385
00:12:24,560 --> 00:12:25,640
It takes about two minutes.
386
00:12:25,640 --> 00:12:27,960
Microsoft says it could take up to 24 hours
387
00:12:27,960 --> 00:12:30,040
for the sync to complete, but in practice,
388
00:12:30,040 --> 00:12:31,360
it's usually much faster.
389
00:12:31,360 --> 00:12:33,760
Third step, onboard your devices.
390
00:12:33,760 --> 00:12:35,520
For Windows machines, the Defender sensor
391
00:12:35,520 --> 00:12:37,840
is already built into the operating system.
392
00:12:37,840 --> 00:12:38,880
You don't need to install anything.
393
00:12:38,880 --> 00:12:40,120
You just need to turn it on.
394
00:12:40,120 --> 00:12:41,880
For Mac OS Linux, Android, and iOS,
395
00:12:41,880 --> 00:12:44,240
you'll need to download and install the Defender agent.
396
00:12:44,240 --> 00:12:46,160
But once it's installed, the same policies
397
00:12:46,160 --> 00:12:47,680
apply across all platforms.
398
00:12:47,680 --> 00:12:50,080
Fourth step, create security policies.
399
00:12:50,080 --> 00:12:51,680
Microsoft provides security baselines
400
00:12:51,680 --> 00:12:53,520
that follow industry best practices.
401
00:12:53,520 --> 00:12:55,000
These are pre-configured settings
402
00:12:55,000 --> 00:12:56,800
that cover the most important protections.
403
00:12:56,800 --> 00:13:00,160
You can use them as is or customize them for your environment.
404
00:13:00,160 --> 00:13:02,920
If you're not sure where to start, just apply the baseline.
405
00:13:02,920 --> 00:13:05,040
It's better than leaving things at default.
406
00:13:05,040 --> 00:13:07,240
Fifth step, monitor and respond.
407
00:13:07,240 --> 00:13:09,080
The Defender portal gives you a single view
408
00:13:09,080 --> 00:13:11,560
of all your alerts, incidents, and device health.
409
00:13:11,560 --> 00:13:13,520
You can investigate suspicious activity,
410
00:13:13,520 --> 00:13:15,920
track your security posture, and respond to threats
411
00:13:15,920 --> 00:13:16,680
from one place.
412
00:13:16,680 --> 00:13:18,680
You don't need to jump between multiple tools.
413
00:13:18,680 --> 00:13:20,320
Now, an honest word of warning.
414
00:13:20,320 --> 00:13:22,680
If you're a small team without dedicated security staff,
415
00:13:22,680 --> 00:13:24,320
the technology alone isn't enough.
416
00:13:24,320 --> 00:13:25,600
The system generates alerts.
417
00:13:25,600 --> 00:13:26,680
Someone needs to watch them.
418
00:13:26,680 --> 00:13:28,200
Someone needs to tune the settings,
419
00:13:28,200 --> 00:13:30,360
and someone needs to respond when something happens.
420
00:13:30,360 --> 00:13:31,880
That's why many small organizations
421
00:13:31,880 --> 00:13:34,640
pay a Defender for endpoint with a managed detection
422
00:13:34,640 --> 00:13:36,280
and response service or MDR.
423
00:13:36,280 --> 00:13:37,600
It's like hiring a security guard
424
00:13:37,600 --> 00:13:39,400
to watch the cameras you just installed.
425
00:13:39,400 --> 00:13:41,840
The technology is powerful, but it still needs human eyes.
426
00:13:41,840 --> 00:13:43,400
You don't need to do all of this at once.
427
00:13:43,400 --> 00:13:44,560
Start with the basics.
428
00:13:44,560 --> 00:13:45,760
Turn on the connection.
429
00:13:45,760 --> 00:13:47,400
Onboard your devices.
430
00:13:47,400 --> 00:13:50,320
Apply the baseline and build from there.
431
00:13:50,320 --> 00:13:51,680
So that's Defender for endpoint.
432
00:13:51,680 --> 00:13:53,280
It's not just a better antivirus.
433
00:13:53,280 --> 00:13:55,600
It's a whole new way to protect your devices.
434
00:13:55,600 --> 00:13:57,120
Prevention blocks what it can.
435
00:13:57,120 --> 00:13:58,800
Detection finds what slips through
436
00:13:58,800 --> 00:14:01,680
and responds acts fast before any real damage happens.
437
00:14:01,680 --> 00:14:05,360
All three layers work together using the Microsoft 365 tools
438
00:14:05,360 --> 00:14:06,200
you already have.
439
00:14:06,200 --> 00:14:08,240
If you're not sure your current security is enough,
440
00:14:08,240 --> 00:14:10,000
drop a comment with your biggest worry.
