Perimeter is a vendor risk management (VRM) platform founded in 2017 and headquartered in Minnesota. The company was originally known as ProcessBolt before rebranding to Perimeter. Its platform is designed to manage the full third-party risk lifecycle, from vendor onboarding and security assessments through to continuous monitoring and issue response. The platform includes several core capabilities. Automated assessment tools allow organizations to send, track, and analyze vendor security questionnaires without relying on manual processes or spreadsheets. A feature called DocAI analyzes vendor-supplied documentation and extracts relevant security information, citing its sources for transparency. ThreatScape, another platform component, provides continuous monitoring of vendors using first-party threat intelligence data rather than third-party purchased feeds. Perimeter validates vendor attestations against real-time threat intelligence to identify discrepancies between what vendors report and their actual security posture. The platform also supports organizations in responding to security assessments they receive from their own clients, maintaining a library of pre-approved answers for RFPs and customer questionnaires. Target customers include compliance, security, and risk teams across healthcare, finance, legal, and technology sectors. Clients listed on the company's website include Medtronic, Boston Scientific, Tampa General Hospital, Orlando Health, Houlihan Lokey, and Scholastic, among others. The platform operates on an unlimited user licensing model and is designed for rapid deployment, with onboarding targeting a go-live timeline of approximately five days. The company reports a 4.8-star rating on G2.
