10 Red Flags to Investigate When Evaluating AI Pentesting Vendors

AI pentesting has emerged to help security teams deal with today’s scale challenges and allow them to do more testing with high-quality results. But there are also a lot of vendor claims and promises about powerful AI capabilities and results. To streamline your evaluation process, we share a few red flags to look out for and question early in your evaluation process.

Key takeaways<br>AI pentesting has emerged to address the changing attack surface, but there is little consensus about what these solutions should or could entail.<br>Most AI pentesting solutions today break down roughly into three categories, AI-assisted pentesting, hybrid/AI-augmented pentesting, and AI-led autonomous pentesting.<br>When evaluating AI pentesting vendors, beware red flags like lack of clarity on level of autonomy or safety guardrails or bold claims about false positives or vulnerability coverage.<br>Before selecting an AI pentesting solution, consider several factors, including validation and accuracy, autonomy and adaptation, safety and governance, operational integration, scalability and economics, and transparency and reporting.<br>AI pentesting myths vs. reality<br>AI pentesting has emerged to help security teams deal with today’s scale challenges and allow them to do more testing with high-quality results. But as an emerging technology, there is no consensus yet on what “AI pentesting” actually entails. For instance, AI pentesting could refer to:<br>AI-assisted tools (LLM wrapper around scanners)<br>ML-enhanced vulnerability detection<br>AI agents that reason, adapt, and chain exploits<br>Fully autonomous exploitation or scripted automation<br>Open source or commercial products<br>There are also a lot of vendor claims and promises about powerful AI capabilities and results. How do you make sense of it all and make smart decisions when there’s limited information and a fair amount of “AI washing”? To streamline your evaluation process, we share a few red flags to look out for and question early in your evaluation process below.<br>For more detailed evaluation guidance, download our new buyer’s guide: What to Look for In AI Pentesting. To get a quick look at the types of AI pentesting solutions and questions to ask vendors, see our new decision framework.<br>Red flag 1: Autonomous claims without clarity<br>A vendor may claim their solution is “autonomous,” but how autonomous is it really? Many solutions require your team to be involved at some point, or several points, between the identification and reporting of a finding. Ask vendors about the level of human involvement, and request a demo of the system working from test kick-off to report generation.<br>Red flag 2: Promises of zero false positives<br>“Zero false positives” is a bold claim. Ask for details on how they are reducing false positives. Are they validating findings with proof of exploits? Can you upload source code or SAST findings to improve the accuracy of results?<br>Red flag 3: Fuzzy proof of concept<br>Can you trial the solution in your own system, or only in the vendor’s exclusive environment? Beware of restrictive trials that don’t take place in real-world scenarios.<br>Red flag 4: Continuous, yet scheduled<br>If the vendor touts “continuous” testing, but also wants to schedule a monthly or weekly test, that’s a dubious claim. For teams deploying code to production frequently, a monthly or weekly test may not be sufficient. Ask the vendor to clarify “continuous,” who can trigger tests, if you can access the solution via API, if you can test incrementally, and the typical window between code deployment and testing.<br>Red flag 5: Coverage numbers that are vague or too good to be true<br>Investigate any claims of covering huge numbers of vulnerabilities, like “thousands of vulnerability classes,” or a lack of details on coverage, like “the OWASP Top 10.” Ask whether it can unearth net-new vulns. Could it find a zero day, or is it just looking for existing patterns? Can it chain multiple findings to identify business logic flaws like IDOR?<br>Red flag 6: No proof of exploits<br>How transparent are the findings? Ask to see a sample findings report from a real customer. Make sure you get enough detail that you could reproduce the findings.<br>Red flag 7: No details on data governance<br>Make sure the vendor has clear, solid answers about data governance. Ask about what data is retained (requests/responses, creds, tokens, findings), and how it’s retained. Also ask whether customer data used for training (opt-in/opt-out).<br>Red flag 8: No mention of safety guardrails<br>If there’s no talk about how the solution keeps AI agents from affecting production systems, dig deeper. Make sure they have detailed answers on guardrails and how...
