SecurityAbrot Cyber
Cybersecurity firm site with a free browser-side security toolkit: password strength analyzer, k-anonymity breach check, hash generator, security headers analyzer, and more.
Abrot Cyber pairs a firm-style landing page with a genuinely useful toolkit that runs entirely browser-side. The k-anonymity breach check is the standout: it uses the same partial-hash technique as Have I Been Pwned, so a password can be checked against known breaches without ever transmitting the password itself.
Every tool was built to teach the underlying concept — the port scanner simulates real TCP handshake logic without touching real hosts, and the headers analyzer explains each missing header's risk.
- 7 free tools: password strength analyzer, generator, hash tool, breach check
- k-anonymity breach check — queries never send your full password anywhere
- Security headers analyzer + port scanner simulator
- Animated hero, dark/light theme
