Autopen is now closed to new users. If you're looking for LLM-powered pentests, we've heard good things about Aikido, Casco, and XBOW.

Find vulnerabilities before hackers with AI

Advanced LLMs make individual hackers more powerful than ever. Defend your products against them with continuous penetration testing driven by the latest and most powerful LLMs.

Some of Autopen's accomplishments:

Discovered over a million exposed user records with PII for a startup

Awarded the largest single bug bounty payout in an Alphabet subsidiary’s history

Found an endpoint leaking user PII for a frontier AI lab

How it works

Add your assets

Add the domains, APIs, or applications you want tested. We recommend connecting a staging or non-production environment that's configured identically to production.

Autopen attacks and triages

Our agents, using multiple frontier LLMs from Anthropic, DeepMind, and OpenAI, break into your assets. Then, you – or Autopen staff, depending on the engagement – validate the findings.

Integrate for continuous testing

For continuous testing, integrate Autopen with your CI/CD pipeline.
