About Cyberscan
Free, instant, private security tools for everyday use.
What it is
Cyberscan is a collection of fast, free security tools for anyone who wants to check a password, find out if their email has been exposed in a data breach, scan a suspicious link, or generate a cryptographically strong password.
No account required. No data stored. No tracking. Just tools that work.
The tools
Password Tester — Realistic strength analysis using the zxcvbn algorithm, the same engine trusted by Dropbox and 1Password. Runs entirely in your browser.
Password Creator — Cryptographically secure passwords generated locally using crypto.getRandomValues(). Fully customisable; nothing ever leaves your device.
Email Breach Check — Checks your address against billions of records from confirmed data breaches, powered by the XposedOrNot public API. Cyberscan proxies the request and discards it immediately.
URL Scanner — Analyses any suspicious link through 70+ antivirus and blacklist engines simultaneously via VirusTotal. Know before you click.
Hash Generator — SHA-256, SHA-512, MD5 and more, computed client-side via the Web Crypto API. Verify file integrity without uploading anything.
QR Reader — Decode and immediately scan the URL hidden inside a QR code for threats, before your phone opens it.
Core principles
Privacy by design. Every tool that can run in the browser does run in the browser. For tools that require external APIs, Cyberscan acts as a privacy proxy — your data is forwarded and immediately discarded, never logged or associated with you.
Speed over complexity. Pure HTML, CSS, and JavaScript served from a global edge network. Results in milliseconds with no server-side logic in the critical path.
Honest results. No inflated threat scores, no dark patterns to upsell a paid plan. Results reflect real-world risk assessments from the same sources used by security professionals.
Free forever. No plans, no subscriptions, no paywalls. Security basics should be accessible to everyone.
