Uncover critical vulns so you can ship with confidence
AI-powered, human-verified deep security audits that find critical vulns others miss
What We Do

We combine our frontier LLM-powered AI AppSec Agent with a team of in-house cyber experts to uncover important vulnerabilities that others miss. No new tools to learn or noise to sift through -- just high quality findings.

We take the time to understand your business & application - code, infra, business context - to ensure findings are relevant & prioritised. Protect your most important assets, not just what's easy to scan.

Our AI agent works across all major programming languages (e.g. JavaScript, Python, Java, PHP) and frameworks. If it’s a web app or API, we can review it.

We never train on customer code and take customer data security incredibly seriously. From data storage, personnel security, to AI agent security, we safeguard your data at every step of the process.
