Picus Security Warns of Coverage Gaps in Agentic Penetration Testing

Picus Security has published research detailing the limitations of agentic penetration testing, a method that uses AI agents to autonomously discover and exploit security weaknesses. While these AI-powered tools can uncover complex attack paths, their effectiveness is constrained by built-in safety restrictions and network limitations. Specifically, safety mechanisms designed to prevent unintended damage and network segmentation that isolates critical assets prevent these tools from reaching and testing high-value targets. The analysis warns that organizations relying solely on agentic penetration testing may have significant security gaps, as many critical assets and vulnerabilities remain untested. To address these blind spots, Picus Security recommends combining agentic penetration testing with exposure validation and breach simulation. This integrated approach provides a more comprehensive view of an organization's security posture by validating exploitable paths and simulating real-world attack scenarios, ensuring that assets inaccessible to agentic testing are still assessed through alternative methods. The findings underscore the need for a multi-layered security testing strategy that combines automated AI-driven testing with human-led breach simulation to achieve full coverage.
