Automated Pentesting Tools Face Limitations Due to ‘PoC Cliff,’ Picus Security Warns

Automated penetration testing tools typically yield strong initial results but then reach a plateau, failing to explore significant portions of the attack surface. Picus Security identifies this limitation as the 'PoC cliff,' which leads to dangerous validation gaps.

What happened

Picus Security highlighted that while automated pentesting tools can quickly identify vulnerabilities at the start of assessments, their capabilities sharply decline afterward. This decline, termed the 'PoC cliff,' results in many attack surfaces remaining untested and unvalidated.

Why it matters

The presence of the 'PoC cliff' in automated pentesting tools means organizations may overestimate their security posture, as these tools do not fully validate all threat vectors. This gap leaves firms potentially exposed to risks that the automated tools fail to detect.

Key technical details

The 'PoC cliff' refers to the phenomenon where automated penetration testing tools cease to progress after initial Proof of Concept (PoC) exploits are identified. Consequently, large parts of the attack surface remain unexamined, leading to incomplete vulnerability validation and security blind spots.
