Pre-Assessment

Vendor Intake & Onboarding

Streamline vendor onboarding with custom workflows that give procurement and risk teams instant visibility into third-party profiles and risk levels.

Build the Right Assessment

Use Perimeter’s robust template library (NIST, ISO, SIG, HIPAA, ESG) or create your own - from basic questionnaires to complex frameworks.

Tier Vendors by Risk

Automatically categorize vendors by risk level with configurable workflows - so you can prioritize resources and diligence where it matters most.

Assessment

Upload. Assess. Done.

Instead of starting with a 300-question survey, vendors upload their documentation into Perimeter’s secure platform.

AI-Driven Assessments with Source Citations

Perimeter AI reviews the documentation, answers each assessment question, and cites the exact source for every answer - so verification is instant and effortless.

Real-Time Validation with Continuous Monitoring

Perimeter’s Monitor module checks vendor internet-facing assets and validates that responses align with real-world security posture.

Vendor Review & Finalization

Vendors confirm or edit the pre-filled responses and fill in any remaining gaps. No more back-and-forth over every question.

Fast, Verified Reviews

The completed assessment returns to your team, fully cited, fully validated - and ready for quick review.

Post Assessment

Risk Remediation, Automated

Issues are automatically generated based on findings - so you can document risks and track remediation with ease.

Continuous Monitoring

Perimeter continuously monitors vendor posture - alerting you to material changes in real time.

Analytics That Power Decisions

Custom dashboards surface the trends, risks, and metrics that matter - giving you full control and visibility across your vendor network.

I didn't know I needed it, now I have to have it

If you want a tool that comes pre-populated and you can start using day one, get this one. If you want a tool and is highly customizable and can quickly be modified to suit your needs. If you want a tool that has excellent support, use this one. I'm certain there are things that Perimeter doesn't do excellently, but I haven't found them yet.
