Perimeter

Perimeter, known as ProcessBolt until it rebranded in September 2025, is a third-party and vendor risk management platform that automates the parts of vendor security review that have traditionally consumed the most analyst time: sending and chasing security questionnaires, reviewing evidentiary documentation, and tracking remediation. Its AI-driven layer adds automated questionnaire responses, document intelligence for parsing vendor-submitted evidence (SOC 2 reports, policies, certifications), and continuous monitoring that pulls in proprietary attack-surface data on a vendor’s external footprint rather than relying solely on point-in-time self-attestation.

Founded in 2017 and headquartered in Minnetonka, Minnesota, the company grew largely as a self-funded SaaS business, with strategic backing at various points from healthcare-sector investors including Orlando Health Ventures and Tampa General Hospital’s TGH Innoventures — a reflection of healthcare being one of its stronger customer verticals given the sector’s heavy reliance on third-party vendors handling protected health information. The company has historically priced as a flat-rate subscription rather than per-seat or per-assessment, a deliberate positioning against vendor risk platforms that charge in ways that discourage assessing a full vendor population.

Third-party and vendor risk management is a genuine, persistent GRC pain point as breaches increasingly originate through the supply chain rather than direct compromise, and the September 2025 rebrand to Perimeter signals a strategic push toward positioning the platform as a real-time, always-on vendor risk defense layer rather than a periodic-assessment tool. As a small, historically bootstrapped-leaning vendor, it still competes against much larger, more heavily funded third-party risk platforms (OneTrust, Prevalent, UpGuard) with broader integration ecosystems and larger vendor-risk-intelligence datasets.
