Software Buyer Brief
Third-Party Access Management Software Checklist Before Buying
Short answer: buy third-party access management software only if it inventories external identities, enforces least privilege, supports just-in-time access, records privileged sessions, expires access automatically, proves offboarding, and exports audit evidence.
NIST SP 800-161 Rev. 1 frames supply chain risk as an enterprise security issue. Access by vendors, contractors, support teams, auditors, agencies, and partners is one of the most operational parts of that risk.
The buying question is not only “which vendor is risky?” It is “which external people and systems can enter our environment today, why, with what privileges, and when will that access end?”
Start With External Identity Inventory
The tool should discover third-party users across identity providers, SaaS apps, VPNs, privileged access tools, cloud accounts, source code systems, support portals, and shared mailboxes.
Ask whether each identity has a sponsor, vendor, contract, access purpose, start date, expiration date, and business owner.
Require Just-In-Time Access
Standing access is the main risk. The product should support request workflows, approvals, time-bound access, session launch, step-up MFA, policy checks, and automatic revocation.
For privileged third-party access, ask whether the tool can avoid exposing passwords and secrets directly to the vendor.
Record And Review Sessions
Support vendors often need powerful access for short periods. The software should log commands, screen sessions where appropriate, file transfers, database access, admin console activity, and ticket references.
Session recording should be searchable, protected, and tied to an approved request, not stored as unmanaged video files.
Prove Offboarding
Third-party access should expire automatically when contracts end, projects close, users leave the vendor, or approvals lapse. The platform should reconcile active accounts against expected access and create tasks for stale identities.
Ask the vendor to show a monthly access review and a completed offboarding evidence report.
Third-Party Access Review Table
| Requirement | Demo question | Buying signal |
|---|---|---|
| Inventory | Can it find external users across apps and identity stores? | Hidden vendor access is reduced. |
| Ownership | Can every external account have a sponsor and expiration? | Access has accountability. |
| JIT access | Can access be approved, time-bound, and revoked automatically? | Standing privilege is minimized. |
| Session control | Can privileged vendor sessions be logged and reviewed? | High-risk work is traceable. |
| Offboarding | Can stale access be detected and closed with evidence? | External accounts do not linger. |
Questions To Ask Before Buying
- Which apps, identity providers, VPNs, cloud accounts, and PAM tools are supported?
- Can each external identity be mapped to a vendor, sponsor, contract, and purpose?
- Can access be granted just in time and revoked automatically?
- Can privileged vendor sessions be recorded or command-logged?
- How are shared vendor accounts discovered and eliminated?
- Can contractors use step-up MFA and device posture checks?
- Can access reviews include session history and ticket references?
- Can offboarding evidence export by vendor and system?
Red Flags In A Third-Party Access Demo
- The product manages requests but cannot discover existing external users.
- Access expiration is optional or manually maintained.
- Vendors still receive shared passwords.
- Session logs are not tied to tickets or approvals.
- Offboarding reports show tasks but not completed revocations.
- Access reviews cannot separate vendors, contractors, partners, and employees.
Demo move: ask the vendor to onboard a contractor, grant one-hour privileged access, record the session, revoke access automatically, and export the offboarding evidence.

FAQ
Is third-party access management the same as vendor risk management?
No. Vendor risk management assesses vendor risk. Third-party access management controls the actual accounts, sessions, privileges, expirations, and evidence for external access.
Why is just-in-time access important?
It limits how long external users hold access. That reduces exposure if a vendor account is compromised or no longer needed.
Should vendor sessions be recorded?
For privileged support, administrative access, and sensitive systems, session recording or command logging can provide accountability and investigation evidence.
How should contractor access expire?
Access should have an expiration date tied to contract, project, ticket, or approval period, with automatic revocation and review reminders.
What evidence should auditors see?
External user inventory, sponsors, approvals, MFA status, session records, access reviews, expiration records, revoked accounts, and exception history.
