Terra Security

Terra Security is an agentic offensive security platform for continuous penetration testing, built from the start around a human-in-the-loop architecture. A coordinated swarm of dozens of fine-tuned AI agents continuously scopes environments, discovers attack surfaces, generates hypotheses, and validates vulnerabilities, running thousands of tests tailored to each organization's business context and risk profile and adapting in real time as applications change. When agents hit their limits, Terra's agentic gateway brings human pentesters into the same agentic workflow with full context preserved, combining the accuracy, safety, and depth of expert testers with the scale of automation; the same gateway lets MSSPs supervise continuous AI-driven testing across client environments. Terra Portal, launched March 2026, is an agentic desktop application serving as the execution layer for testers overseeing AI-driven testing in live production, which the company says cuts the vulnerability discovery-to-fix cycle from an industry average of nearly three months to hours without sacrificing safety or compliance. In May 2026 Terra unified web application, AI system, and network infrastructure testing under one platform, positioning itself as the only continuous agentic platform validating exploitable risk across multi-vector attack chains spanning all three surfaces. Reports deliver proof of exploitability with remediation prioritized by business impact. Founded in 2024, Terra raised $38M within roughly a year ($30M Series A led by Felicis with Dell Technologies Capital and SVCI), serves Fortune 100 clients, added former Google CISO Gerhard Eschelbeck to its board, and became the first AWS Partner to achieve the Security Competency for Autonomous Security Validation. Within the offensive cluster, Terra is the human-in-the-loop, multi-surface entrant alongside XBOW's bug-bounty-proven external testing and Horizon3's production-safe internal pentesting.
