About ZeroDayCops

ZeroDayCops builds tools for people who take security seriously. We provide 100+ free browser-based utilities alongside purpose-built applications for endpoint monitoring and security auditing.

Our tools are designed with a simple principle: respect the user. Client-side tools run entirely in your browser — no data is sent to any server. Server-side tools process and discard; we do not store your inputs beyond the time needed to return a result.

We build for developers, security engineers, IT administrators, and technically literate power users who need reliable, fast, and honest tools.

Why "ZeroDayCops"?

A zero-day is a vulnerability that exists before anyone knows about it. We build the tools that help you find and fix issues before they become incidents. The name is a reminder: security is about vigilance, not reaction.
