About

Fast, free, defensive tools for the people who keep systems safe.

BlueTeamKit is a small collection of practical security utilities built for IT and security practitioners: sysadmins triaging a suspicious email, analysts checking a CVE against KEV, developers hardening response headers. Every tool does one job, works immediately, and explains its output.

Three principles govern everything here:

• Defensive only. Validators, checkers, decoders, and lookups — no attack tooling.
• No fake authority. Tools report what was observed, cite their data sources, and state their limits plainly.
• Privacy by architecture. Wherever possible tools run entirely in your browser; the few server-side checks state exactly what is fetched and keep nothing.

BlueTeamKit is a project of The Exploit HQ, a cyber threat intelligence channel. The site is sustained by clearly-disclosed affiliate links and our own products — never by selling your data.
