Built by Founders, For Founders
We started Zero Day because security should empower product launches — not slow them down. We bring expert, manual security reviews early to make risk actionable, practical, and clear.
Vision
A digital ecosystem where every software product launches with bank-grade security built in from day one.


Mission
Make expert security reviews and zero-jargon remediation roadmaps accessible to every growing tech startup.
Approach
Manual, business-focused vulnerability testing that turns complex technical risk into a clear engineering action plan.

Promise
Real-world threat protection designed for customer trust — far beyond superficial compliance checkboxes.
