Vendors often hold the keys to your most sensitive systems. One overlooked account can lead to a major breach. You know the stakes.

A vendor access review checks if third-party permissions match current needs. It spots excessive rights before attackers do. Teams run these reviews to enforce least privilege and stay compliant.

This guide walks you through the process. You’ll get steps, questions, red flags, and a checklist. Follow it to cut risks fast.

What a Vendor Access Review Achieves

Vendor access reviews fit into broader vendor risk management. They ensure outsiders only touch what they need. This aligns with access governance principles.

Think of it as a routine health check for permissions. Without them, vendors keep old access after projects end. That invites trouble.

These reviews support compliance too. Frameworks like NIST Cybersecurity Framework map third-party risks clearly. For example, NIST CSF for third-party risk stresses ongoing oversight. SOC 2 requires vendor controls in trust services criteria.

Run reviews quarterly for high-risk vendors. Do them annually for others. Trigger extra ones after contract changes or incidents.

When to Schedule Vendor Access Reviews

Timing matters. Don’t wait for a crisis.

Schedule reviews every three months for critical vendors. Those with privileged access top the list. Annual checks work for low-risk ones.

Key triggers include:

• Project completion.
• Staff or role changes at your firm.
• Vendor contract renewals.
• Security incidents elsewhere.

Periodic recertification keeps access fresh. Business owners attest to ongoing needs. This ties into least privilege enforcement.

Automation helps. Tools scan for dormant accounts monthly. They flag expired credentials too.

Steps to Prepare Your Vendor Access Review

Start with an inventory. List all vendor accounts, permissions, and last login dates.

Pull data from identity providers like Okta or Azure AD. Check Active Directory for on-prem access. Include cloud services and facilities badges.

Gather docs. Review contracts for access scopes. Note SLAs on logging and MFA.

Assign roles. Security leads the review. Involve IT admins, vendor managers, and compliance. Set a one-hour meeting slot.

Document everything. Use a shared sheet for findings. This creates an audit trail.

Run the Vendor Access Review

Meet as a team. Walk through each vendor one by one.

Ask pointed questions. Does this access still support business goals? Who approved it last? Any recent logins?

Examine controls. Confirm MFA everywhere. Check if sessions log activities. Verify just-in-time access over standing privileges.

Discuss examples. A cloud vendor with admin rights on prod servers? Revoke unless proven essential. Shared accounts? Switch to individual ones.

Rate risks. High if unmonitored. Medium for outdated scopes. Low for justified access.

End with decisions. Revoke, reduce, or renew. Note owners for follow-up.

Vendor Access Review Checklist

Use this checklist every time. It covers essentials.

Item	Check	Notes
Inventory all accounts	Yes/No	List users, roles, systems
Confirm least privilege	Yes/No	Match to job needs only
MFA enforced	Yes/No	All sessions
Logging active	Yes/No	Full audit trails
Last review date	Date	Recertify if over 90 days
Dormant accounts	Yes/No	Deprovision now
Contract alignment	Yes/No	Matches scope

Tick items during the meeting. Summarize gaps post-review. This table speeds up future runs.

Common Red Flags to Watch For

Spot these issues quick. They signal big risks.

Broken MFA setups top the list. No second factor means easy compromise.

Excessive permissions stand out. Vendors with god-mode rights rarely need them.

Missing logs hide actions. Attackers love unmonitored paths.

Dormant accounts linger too long. No logins in six months? Gone.

Offboarded vendors with lingering access? Immediate revoke.

Review questions reveal them:

• Any shared credentials?
• Time-bound access used?
• Business justification current?

Quarterly checks catch most. Vendor access management challenges notes post-project reviews prevent drift.

Handle Follow-Up and Remediation

Act on findings right away. Revoke unneeded access same day.

Track remediations. Assign tickets in your ITSM tool. Set due dates.

Notify vendors. Share only what’s needed. Request their updates.

Reassess in 30 days. Confirm fixes.

Document outcomes. Report to leadership quarterly. Tie to metrics like revoked accounts.

Integrate with third-party risk tools. Automate where possible.

If gaps persist, escalate. Consider booking a discovery call with Bud Consulting for IAM expertise.
