About YSecurity

YSecurity is an on-demand security team for ambitious companies.

We help startups and enterprises achieve compliance, pass audits, and close enterprise deals faster. Our work covers SOC 2, ISO 42001, penetration testing, due diligence and DDQs, risk management, and ongoing security reviews—everything a growing company needs to earn trust from customers and investors.

Unlike traditional firms, we embed directly with your team—joining Slack, stand-ups, and customer calls to solve real problems fast. We bill in 15-minute increments with monthly caps, keeping costs predictable and progress quick.

At YSecurity, every operator is both a security expert and a partner in your mission. We’ve built programs at Apple, Robinhood, Uber, and Pure Storage, and now bring that same precision to teams ready to grow with confidence. What unites us is a shared belief: security should enable innovation, not slow it down.

Team

Our team includes veterans from top companies like Apple, Netflix, and Robinhood, with 200+ years of security leadership. We’ve built and protected systems in the world’s most demanding environments—and now bring that expertise to your business.
