A spotless pentest report can feel reassuring. It can also be misleading.
Run automated pentesting a few cycles in a row and the “new” findings taper off. By the third or fourth pass, the report looks steady. It’s easy for “stable” to read as “secure.” Often, it isn’t. The pace slows. The risk stays.
That gap is the focus of a The Hacker News session with Picus Security. Autumn Stambaugh and Can Yüceel, hosted by James Azar, walk through what automated tools actually validate, where they stop, and how to close what they leave open. For details, see the webinar page linked above.
What a flat report can mean
Sometimes it means you fixed the obvious holes. Sometimes it means the tool hit the edge of what it can see. Automated pentesting is often treated as full security validation. It isn’t.
Picus frames validation as six surfaces. Automated pentesting sits on one of them: the attack path—whether an attacker can move through an environment. That leaves the other five unproven, including detection rules, cloud configurations, identity controls, and AI guardrails. Tuning can sharpen the scan, but it won’t turn an attack-path test into detection or cloud validation.
What the tool can’t tell you
When an automated test exploits a technique, it can show that credential dumping or lateral movement is possible. It cannot tell you whether your SIEM rule fired or your EDR raised an alert. It doesn’t confirm whether the EDR blocked the action, the SIEM logged it, or the SOC had enough signal to act.
That’s the risk: mistaking a reachable path for a defended one.
BAS and Automated Pentesting Answer Different Questions
Breach and attack simulation asks whether a control reacts to a known behavior—blocked, detected, logged, or missed. Automated pentesting asks how far an attacker could get through an exploitable path. Swap one for the other, and the gap disappears from the report, not from the environment.
Why this matters for prioritization
If a tool proves a path exists but your controls already block or detect it, that item doesn’t carry the same urgency as one that works silently. Without control validation, teams rank risk with half the evidence missing. The session focuses on turning a pile of findings into a ranked queue based on whether controls actually caught the behavior.
If automated pentesting is standing in for your whole validation program, start by checking this gap.
