PhishClean helps people catch browser threats before reputation systems do.

Boilerplate

PhishClean is a browser security product focused on phishing detection and client-side risk analysis. It helps people spot malicious pages, exposed secrets, token leaks, and browser trust mismatches without routing page contents through a cloud scanner by default. The product is designed around privacy-first detection, fast local analysis, and practical protections for normal browsing workflows.

What PhishClean detects

PhishClean runs 20 detection signals against the page currently open in the browser. Three of them are free permanently; the full set is included in the paid plan and in the trial that starts at install. The signals fall into four groups:

• Phishing mechanics — login forms posting to a different origin than the one displayed, lookalike and homograph domains, and credential fields on pages that have no business collecting them.
• Secret and token leakage — API keys, JWTs and session tokens exposed in page source or storage, covering formats from AWS, Stripe, GitHub, Slack and others.
• Embedded content abuse — hidden, tiny and off-screen iframes of the kind used for clickjacking and silent credential capture.
• Transport downgrades — HTTPS connections silently dropped to HTTP, the mechanic behind SSL stripping on untrusted networks.

Every check runs locally. No URL, page content or form data is transmitted to PhishClean as part of detection, which is why the product works identically on an internal corporate site and a public one.

Why it is built this way

Most browser security extensions answer one question: has this destination been reported before? That works well for catalogued threats and poorly for the first few hours of a campaign, which is precisely when phishing kits do their business. PhishClean was built to answer a different question — what is this page doing right now — so that a phishing page registered this morning is treated no more kindly than one that has been on a blocklist for a month.

The privacy property falls out of that choice rather than being bolted on. A tool that reasons about the page in front of you does not need to send anything anywhere to reach a verdict.

Founder quote

"PhishClean exists because browser security should help people at the exact moment something feels slightly off, without turning their browsing history into someone else's dataset."
