Terra Security provides a Penetration Testing-as-a-Service (PTaaS) platform that combines AI agents with human red-teamers to deliver continuous web application penetration testing. The service uses agentic AI systems to automatically map, exploit, and retest applications in real-time, while senior security engineers validate findings and provide business context. The platform focuses on web application security testing with continuous monitoring capabilities that adapt to code changes and new deployments. It performs exploit validation to reduce false positives and provides business-aware risk assessment that considers organizational context and business logic. Terra Security's approach addresses limitations of traditional point-in-time penetration tests by offering ongoing assessment that covers expanding attack surfaces including microservices, APIs, and new subdomains. The service produces verified, exploitable findings rather than generic vulnerability scans. The platform is designed for organizations with agile development practices that require security testing to keep pace with frequent releases. It provides auditor-ready reports and translates technical findings into actionable development tasks. The service aims to improve ROI by automating repetitive testing tasks while focusing human expertise on complex business logic vulnerabilities.
