Terra Security is an Israeli offensive-security company building an agentic penetration testing platform that replaces slow, point-in-time manual pentests with continuous, AI-driven security validation. Its AI agents probe web applications, external network surfaces, and AI systems in real time, surfacing exploitable vulnerabilities and producing audit-ready reports co-signed by certified human pentesters. The 'human-on-the-loop' governance model keeps experts in control at critical decision points, addressing compliance and safety concerns that block fully autonomous tools. Terra claims to compress pentest cycles from 4-6 weeks to a few hours without added headcount. In September 2025 it raised a $30M Series A led by Felicis with Dell Technologies Capital, and in March 2026 became the first AWS Partner to earn Security Competency for Autonomous Security Validation.
