The problem: “Can you prove it?” keeps showing up
Why this hurts NYC SMBs in particular
Client security questionnaires, cyber insurance renewals, landlord requirements, and vendor reviews often ask for the same proof—over and over. The pain isn’t that you *don’t* have MFA or policies; it’s that proof is scattered across portals, exported ad hoc, and ends up stale.
What “evidence automation” should mean for Microsoft 365 shops
Instead of buying a full GRC platform immediately, you can build a lightweight evidence pipeline using tools you already pay for: Microsoft 365 admin centers, Microsoft Graph, Power Automate, SharePoint, and Purview retention. The goal is repeatable snapshots on a schedule, a human sign‑off, and storage you can’t quietly edit later.
The “evidence map”: decide what you’ll collect and how it will be judged
Evidence should be “auditable,” not just “available”
An auditor (or insurer) wants evidence that is time-bound, attributable, and complete. That means each artifact should have: what it proves, where it came from, when it was captured, and who reviewed it.
Start with four monthly snapshots that cover most requests
These four categories tend to satisfy many baseline security questions without turning your team into screenshot collectors:
- MFA coverage (who is protected and how)
- Privileged/admin role assignments (who has power)
- Device compliance posture (are endpoints meeting policy)
- Backup proof (can you restore and is it recent)
A practical evidence library design (SharePoint-first)
Create one place with predictable naming and metadata
Use a dedicated SharePoint site (or library) named something like Audit Evidence. Set up folders by year and month, or rely on metadata and views to avoid deep nesting.
Recommended folder + file naming convention
Keep it boring and consistent so anyone can find what they need under pressure:
- Folder:
2026/2026-08/ - Files:
MFA-Coverage_2026-08-01.xlsx,Admin-Roles_2026-08-01.csv,Device-Compliance_2026-08-01.json,Backup-Proof_2026-08-01.pdf
Add a simple index list for retrieval
Create a SharePoint List called Evidence Index with columns like:
- Control area (MFA, Admin, Devices, Backups)
- Period (Month/Year)
- Source (Graph, Intune, Admin center, backup tool)
- Artifact link
- Reviewer
- Review status (Approved / Needs action)
- Notes
The pipeline pattern: collect → review → lock
Why “human review” is not optional
Automated snapshots can capture bad states just as efficiently as good ones. A reviewer step turns “we exported something” into “we verified what it means.”
Why immutable/retention storage matters
When evidence can be edited or deleted, it loses credibility. Retention controls also prevent accidental cleanup that destroys proof right before an audit.
Step 1: Build the monthly snapshot collector (Graph + scheduled automation)
Choose your automation lane
For most SMBs, the simplest approach is:
- Azure Automation (PowerShell runbooks) or Azure Functions to run monthly scripts
- Microsoft Graph to pull policy/role/device data
- Save outputs to SharePoint via Graph or a connector
If you already live in Power Automate, you can orchestrate the schedule and approvals there, while still calling scripts for the heavy lifting.
What to collect: MFA coverage snapshot
A practical artifact is a user list with MFA status and registered methods (where available). Common sources:
- Graph reports endpoints (authentication methods registration)
- Entra ID (Azure AD) exports where appropriate
Output suggestion:
- CSV/XLSX with user principal name, enabled status, MFA registration status, last updated timestamp (if available)
What to collect: admin role assignment snapshot
Capture privileged role assignments so you can answer “who has admin rights?” with a dated file.
Output suggestion:
- CSV with role name, principal, assignment type (eligible/active if using PIM), and capture timestamp
What to collect: device compliance summary
If you use Intune, export a compliance posture summary:
- Count of compliant vs noncompliant devices
- List of noncompliant devices with primary user and compliance reason (where available)
Output suggestion:
- JSON + human-readable CSV summary so a reviewer can spot issues fast
What to collect: backup proof (the “restore-ready” evidence)
Backup evidence should prove recency and recoverability, not just that “a job ran.” Depending on your tooling, capture:
- Last successful backup timestamp
- Backup scope summary (which workloads are covered)
- Most recent restore test record (if you do quarterly tests)
Output suggestion:
- PDF/CSV export from the backup platform plus a small “backup coverage” summary file
Step 2: Add review and sign-off (Power Automate approvals)
Route each monthly package to an owner
Set a default reviewer (e.g., IT manager, outsourced IT lead, or operations owner). Use a Power Automate flow triggered when new artifacts arrive in the month’s folder.
What the reviewer should check (and how to keep it quick)
A good review is a short decision with notes, not a novel. A reviewer should answer:
- Does this artifact match the intended period?
- Does it meet the pass criteria?
- If not, is there a ticket or action noted?
- Confirm the capture date matches the month folder
- Spot-check MFA: exceptions documented (service accounts, break-glass)
- Confirm no unexpected admin roles or permanent privileged assignments
- Review noncompliant devices list: owners identified and follow-up created
- Verify backup proof shows recent success and coverage scope
Record approvals so evidence is attributable
Write the approval decision back to the Evidence Index list. Store:
- Reviewer name
- Approval date/time
- Status
- Notes/links to remediation tickets (if needed)
Step 3: Store immutably (Purview retention + access controls)
Use retention to reduce “oops” moments
For many SMBs, the simplest immutable-like approach is:
- Store in SharePoint
- Apply a retention label or retention policy that prevents deletion for a set period (e.g., 3–7 years, depending on your needs)
This makes evidence durable even when staff changes or someone tries to tidy up.
Restrict edits without blocking visibility
Evidence storage should be readable to stakeholders but writable by very few:
- Contributors: the automation account + one admin
- Readers: security/compliance stakeholders
- Approvers: reviewer(s)
Keep the “index” separate from the artifacts
Treat the Evidence Index like a catalog, not the vault. If you need to tighten permissions, you can lock down the artifacts library more strictly while keeping the index readable.
What you’ll be able to answer immediately (without scrambling)
Typical questions this pipeline covers
With four monthly snapshots and approvals, you can usually respond quickly to:
- “Show proof MFA is enabled and monitored.”
- “List your admins and how you control privileged access.”
- “Provide endpoint compliance reporting.”
- “Prove backups are running and recent.”
What it won’t solve by itself
This is evidence collection—not a full risk program. You’ll still need:
- A simple policy set (what you require)
- A remediation workflow (tickets, ownership)
- Periodic restore tests (quarterly is common)
Key Takeaways
- A Microsoft 365–native evidence pipeline can replace last-minute screenshot hunts with scheduled, repeatable snapshots.
- Start with four monthly artifacts: MFA coverage, admin roles, device compliance, and backup proof.
- Add human approval so evidence is interpreted, not just exported.
- Store artifacts in SharePoint with retention controls to prevent deletion and preserve credibility.
- Maintain a lightweight Evidence Index so anyone can retrieve the right proof fast.
Frequently Asked Questions
Do we need a GRC tool to automate SOC 2 evidence collection?
No. Many SMBs can cover a large portion of recurring proof requests using Microsoft 365 exports, Graph-based snapshots, approvals, and retention. A GRC platform can still be valuable later for control mapping and workflows, but it’s not required to stop the screenshot scramble.
How often should we collect evidence—monthly or weekly?
Monthly is a strong baseline for SMBs because it creates consistent points-in-time proof and keeps effort predictable. If you have frequent changes (new hires, device churn, admin changes), consider a “monthly snapshot + weekly exception report” approach.
What’s the difference between “retention” and “immutable storage” in Microsoft 365?
Retention policies/labels can prevent deletion and preserve content for a defined period, which supports evidence integrity. True immutability can vary by implementation and requirements, so align your approach to what your customers/insurer actually ask for.
Can Power Automate do this without scripts?
You can orchestrate scheduling, approvals, and SharePoint storage in Power Automate. For complex exports (roles, device compliance details), scripts (PowerShell/Graph) are often the most reliable way to capture consistent datasets.
Who should be the reviewer if we outsource IT?
Pick someone accountable for the business decision—often an internal operations owner—while the IT provider supplies the technical context. The review step is about confirming the evidence matches your stated requirements and noting exceptions.
