Agentic AI pentesting — AI agents that hack your app like real attackers, in 10 minutes, at startup prices.
Most startups can't afford real security testing, so they ship with the same bugs attackers look for. A traditional pentest costs tens of thousands of dollars, takes weeks to schedule and delivers a PDF even later — too slow for teams that push to production daily. Customers get blocked on security questionnaires and SOC 2 requirements, small teams run without any security engineer at all, and the bugs that actually get exploited are ones a quick scan would have caught. Today's automated scanners cover only a fraction of a real attacker's playbook, and human pentests don't scale down to early-stage budgets.
SecurityInfinity runs autonomous AI agents inside an offensive-security harness of real attack tools — the same class of tooling a human pentester uses — to hit your web app, APIs and cloud the way real attackers do, then proves every finding with evidence and shows the fix. First findings arrive in about 10 minutes from just a URL, not weeks. For teams that need a report for a customer or auditor, security engineers verify and deliver a pentest report mapped to SOC 2, ISO 27001 and OWASP Top 10 in 3 days, with a signed attestation letter and a free retest. AI does the exhausting, repeatable 90%; humans do the judgment calls.
Startups selling to enterprise customers who get blocked on security requirements, teams preparing for SOC 2 or ISO 27001, agencies shipping client apps, and founders operating without an in-house security team — anyone who needs a credible pentest fast but can't justify a USD 30,000+ consulting engagement.
Bottom-up: every startup that sells B2B software eventually needs a pentest report for a customer, auditor or compliance framework (SOC 2, ISO 27001), and regulations like NIS2 and the EU Cyber Resilience Act are pushing that requirement down to smaller and smaller vendors. The global penetration testing market is estimated at multi-billion dollars growing double digits annually, with the shift toward continuous, automated security testing accelerating it. Every company that ships software is a potential customer.
What people use today
Cobalt and Bugcrowd's pentest marketplace: verified human pentesters, but weeks of lead time and manual cost. Automated scanners (Burp Suite, OWASP ZAP, Invicti, Detectify, Astra): broad but shallow — they can't think like an attacker or prove exploitability. Many prospects simply do nothing and hope. Us: agents operating real offensive tooling end-to-end, evidence-backed findings in minutes, human-verified reports in 3 days, at a fraction of the marketplace price.
Why this team wins
1) Credibility that's hard to copy: the founder is a former Deloitte cyber risk consultant, Bugcrowd MVP 2020 (600+ vulnerabilities reported), HackerOne top-100 researcher worldwide 2020 (109 vulnerabilities found), IEEE Senior Member, credited with CVEs in widely used software, and has been thanked by Google, Microsoft, Tesla, Netflix, Oracle, PayPal, Airbnb and the U.S. DoD for security research. That reputation drives organic demand in exactly the community that buys pentests. 2) The harness itself: AI agents driving real offensive-security tools, not a thin LLM wrapper around scanner output — months of hard engineering to replicate. 3) Human verification by experienced offensive security engineers makes findings trusted by customers and auditors.
Offensive security is a craft, and I've spent my career doing it at the highest level: cyber risk consultant at Deloitte, security engineer at Fuze, Bugcrowd MVP in 2020 with 600+ vulnerabilities reported, and a HackerOne top-100 researcher worldwide in 2020 with 109 vulnerabilities found. I'm an IEEE Senior Member, hold CVEs in widely used software, and have been thanked by Google, Microsoft, Tesla, Netflix, Oracle and the U.S. DoD for responsible disclosure. I still lead every pentest we deliver. Building AI agents that hack like a great human pentester requires knowing exactly what a great human pentester does — I do. And having sat on the consultancy side, I know precisely what customers and auditors demand from a pentest report, so the product is built around the real buying criteria, not a scanner feature list.

Founder & CEO · San Francisco, United States · 8 years of experience
Founder & CEO of SecurityInfinity, a San Francisco-based cybersecurity company. I work hands-on with startups and SMBs on penetration testing and offensive security assessments, and I'm building AI to automate the parts of security engineering that shouldn't need a human — from validating findings to qualifying and selling security services. I started the company because I kept meeting founders with real security exposure and no practical, affordable way to fix it. Before SecurityInfinity I spent years in offensive security research and engineering, and my career has been built on breaking systems (ethically) so the people defending them understand exactly what needs to change. I run the company full-time out of San Francisco.
