Most people treat Defender Vulnerability Management like a weather report. They glance at the exposure score, nod, and close the tab.
That’s a waste.
The score isn’t the point. The workflow behind it is. And the part almost nobody uses — the bit that actually moves the needle — is the security baselines assessment sitting right next to it.
Here’s the thing. Patching tells you whether software is current. A baseline tells you whether it’s configured the way it’s supposed to be. Those are two completely different questions, and the second one is where most SMB environments quietly fall apart.
What are security baselines, really?
A baseline is a benchmark of configuration settings — things like password policy, BitLocker, account lockout, audit logging — measured against an industry profile.
In Defender, you assess your devices against the CIS or STIG benchmarks, pick a level (L1 is sensible-default, L2 is locked-down), and the tool tells you, device by device, setting by setting, where you comply and where you don’t.
Not “you’re missing 14 patches.” More like “BitLocker isn’t enforced on 9 machines and your audit policy is wide open.” That’s the stuff attackers love and scanners ignore.
The security baselines assessment documentation walks through the profile options if you want the full menu.
Step-by-Step: Build a baseline profile
You’ll need Defender for Endpoint Plan 2 with the MDVM add-on, or the MDVM Standalone licence. Then head to the Microsoft Defender portal → Exposure management → Baselines assessment.
Create the profile
Give it a name, choose your benchmark (CIS or STIG), choose your OS, choose your level. Start at L1. You can tighten later — leading with L2 just buries you in red.
Scope it to a device group
Don’t boil the ocean. Point it at one group — a handful of servers, or the managed laptops — and let it run.
Read the results by setting, not by score
Open the profile and sort by compliance. Each failing setting lists exactly which devices miss it. This is your work queue.
Now the part that earns its keep: exceptions
Here’s the reality every MSP knows. Some findings you can’t fix. The line-of-business app needs that legacy setting. The client won’t approve the downtime. The vendor says “don’t touch it.”
So what do most people do? Nothing. The finding sits there, red, forever — and after a while everyone stops looking because the dashboard is always angry.
That’s the trap. A permanently-red dashboard is the same as no dashboard.
The fix is the exception workflow. When you genuinely can’t remediate something, you file an exception — with a justification and an expiry date — and that finding drops out of your active exposure number. It doesn’t vanish. It’s parked, documented, and time-boxed.
Request the remediation first
For anything you can fix, connect Defender to Intune (it’s a toggle in the portal) and raise a remediation request straight from the recommendation. It lands in Intune as a tracked task instead of a Post-it note. The remediation request process covers the Intune connection.
File an exception for the rest
For the genuine “we can’t touch that,” create an exception with a real reason and a review date. The exceptions overview explains the justification types and how exceptions affect your exposure score.
“Doesn’t an exception just hide the problem?”
No. Hiding is when you ignore the red and hope. An exception is a decision — recorded, owned, and due for review. The difference is accountability.
Why this actually changes behaviour
Once you’re running baselines plus a disciplined exception workflow, “we can’t patch that one” stops being a silent gap. It becomes a documented, time-boxed choice with someone’s name on it.
That’s not a security feature. That’s a governance habit.
And it’s the exact thing that turns a vague “yeah, we’re secure” into a report you can hand a client.
If you’re not showing your clients their baseline posture and the exceptions you’ve signed off on, you’re leaving value — and trust — on the table.
The exposure score was never the deliverable. The conversation it lets you have is.
