Agentic Offensive Security at Scale

Hex Security builds AI agents that run continuous penetration tests against your apps and infrastructure. Instead of a once-a-year penetration test, Hex Security's agents works 24/7 to find and verify critical vulnerabilities so you can prevent them before attackers.

Co-Founder, Hex Security. Previously, I was building robots that learned from each other by sharing skills on-chain, and researching World Models that give robots complete environmental understanding. Our robot became the first in history to ring the NASDAQ bell. I studied Math at University of Waterloo.

Hex Security: AI that Hacks before Attackers do
See original launch post

We're @Huzaifa Ahmad, @Ahmad Khan, and @Prama Yudhistira (@Hex Security, W26). We built AI agents that automate penetration testing.

In the past few weeks, our agents found critical vulnerabilities in dozens of YC companies (ones you’ve heard of): SQL injection exposing billions of records, demonstrated a PoC worm that could infect entire networks, gained access to hundreds of codebases, and more. Through this, we have prevented an estimated $3B+ in potential damages (based on exposed record counts and IBM's Cost of a Data Breach benchmarks).

The problem: Companies lose $10T+ annually to preventable vulnerabilities, yet most pentest once a year because it's manual, expensive, and slow. By the time you get the PDF, your codebase has changed.

And that gap is widening. In September 2025, Anthropic caught Chinese state-sponsored hackers using AI to run 80-90% of an attack autonomously — thousands of requests per second, speeds no human team could match. The attackers have AI now, and defenders need it too.

What we built: AI agents that run continuous penetration tests against your apps and infrastructure. They find vulnerabilities, chain exploits together, and deliver actionable findings with reproduction steps — at a fraction of the cost of traditional pentesting.
