Periphery is a cybersecurity company providing embedded, device-level threat management for critical industrial and defence platforms. Its lightweight, architecture-agnostic agent secures, fingerprints, and continuously monitors devices, detecting unauthorized changes and hardening what is risky even in constrained, offline, or air-gapped environments. The platform spans three products: Insights (point-in-time security evaluation with agent-based pen-testing and SBOM risk analysis), Vantage (on-prem intelligence that establishes a known-good baseline, detects change, and restores devices), and Outpost (real-time on-device threat detection and prevention for air-gapped deployments). Periphery targets regulatory compliance across NDAA, EU CRA, NIS2, UN R155, UN R156, and IEC 62443. It is a Techstars portfolio company.
