Defend 365 finds it. SIA explains it.You fix it, or ask a Defender.
Defend 365 is one system: continuous testing of your Microsoft 365 tenant, an AI that explains the specific control in front of you, and screened Microsoft security experts you can bring in whenever you want a specialist alongside your team.
01 · Defend 365 finds it
Ensure Microsoft Authenticator enforces number matching and additional context
412 of 1,840 accounts on plain approve/deny push · number matching not enforced
700+ tests run continuously across identity, devices, data, apps and AI. Drift is caught as it happens.
02 · SIA explains it
SIA · scoped to CIS.M365.5.2.3
SIA already has this test, its output in your tenant and the framework it maps to. Ask why it failed.
Test-scoped guidance: risk, evidence, remediation steps and PowerShell. SIA advises. It does not decide.
03 · You choose the route
Three routes, one improvement loop. You decide which one this control deserves.
Defenders · human expertise, in the product
When the problem needs a specialist, don't start another consultancy search.
Send the finding to a Defender. The test result, evidence, affected scope, framework context and the SIA conversation go with it.
One finding
A single failed control, handed over with its output.
A group of findings
A cluster that belongs to one underlying design problem.
An entire framework
A scoped programme against CIS, NIS2 / CBW, BIO or NEN 7510.
Every Defender is screened
Verified and reviewed by Defend 365 before joining the network.
Configuration drifts quietly.Exposure does not wait for your next audit.
Change is constant
New services, new defaults, new admins. A tenant that was hardened last quarter is not hardened today.
A list is not a fix
Posture tools are good at producing findings. Teams stall on what to do first and whether it is safe.
Expertise is the bottleneck
Some work genuinely needs a specialist - and finding the right one takes longer than the fix.
See
One honest read of your Microsoft 365 environment.
700+ tests run continuously across identity, devices, data, apps, infrastructure and AI. Everything below is the result of testing, not a questionnaire.
- Switch between tenants, or read them all in one overview
- Choose which frameworks count towards your score
- Run a new scan whenever you need one
- Open the exact failed control and its result in your tenant
- Track changed, regressed and fixed tests against the previous scan
- See which Microsoft services drive the open risk
Try it
Walk the loop yourself.
This is the working surface of Defend 365 with seeded demo data: switch tenants, run a scan, open a failed control, ask SIA in context and accept a risk with a note. Nothing here connects to a live tenant.

Understand
Open the test. Ask why. Fix it with context.
SIA is a conversation attached to the evidence. Open any failed control and SIA already knows which test you are looking at, what it returned in your tenant, what risk it represents, and how to remediate it - down to the PowerShell.
Chat with SIA about CIS.M365.1.1.2
I have the result of this test and its output. 7 Global Administrators found · 0 cloud-only · 5 synced from on-premises AD. Ask me anything about it.
Fix
Three routes. One improvement loop.
Not every security problem needs a consultant. The ones that do should reach the right one immediately.
Automate
Apply supported configuration changes directly from Defend 365, where the change can be safely standardized.
Guide
Step-by-step remediation your own Microsoft 365 team can carry out with confidence.
Escalate
Hand specialist work to a screened Defender with the full technical context attached.
Prove
One fix. Four frameworks.
Frameworks are not a separate compliance exercise. The same tenant evidence is mapped to CIS, NIS2 / CBW, BIO, NEN 7510, ISO 27002 and more - so remediation moves your evidence automatically.

Pass rates move when the control is re-tested, not when a box is ticked.
Work handed to a Defender comes back into the same loop.
Completed specialist work returns to Defend 365, the control is tested again, and your framework evidence updates with it.
Running many tenants? Prioritize across all of them.
Defend 365 for MSPs →Every Defender is screened
Specialists are verified and reviewed before they can receive scoped work. There is no open marketplace signup.
Prevention, stated plainly
Defend 365 reduces preventable exposure. It does not replace a SOC or MDR service.
Demo data, labelled as such
