Not another AI pentester

Security that thinks
like a defender

Most AI security tools act like automated pentesters — they probe for weaknesses, generate a list, and leave your team to figure out what matters. But defending a real product is a different job. It means prioritizing the risks that actually matter, building layers of protection so one mistake doesn't become a breach, and improving security without slowing down shipping. Tachyon is built for that job.

How we think about security

Risk that matters

A list of 200 findings isn't a security strategy. Tachyon identifies the vulnerabilities that are actually exploitable, prioritizes by real-world impact, and helps your team focus on the fixes that move the needle — not the ones that just pad a report.

Defense that ships

Security that blocks your roadmap isn't security — it's a bottleneck. We help teams build structural defenses that compound: code that fails closed, access scoped to what each component actually needs, layers designed so that one gap can't compromise the system.

We've already found critical vulnerabilities in popular open-source projects. See our discoveries.

Who's building Tachyon

Rahul Govind

Founder, CEO

Rahul spent his career building infrastructure where security failures have outsized consequences — and where getting security wrong means the product doesn't ship. At Databricks he built access control and release safety for Delta Live Tables. At Pure Storage he worked on distributed systems at the kernel and VM level. His cryptography research on secure multiparty computation was published at ACM CCS 2019. He holds an MS in Computer Science from UIUC and a B.Tech from IIT Bombay.
