Scam Guard is a free browser extension that stops phishing, scam and malicious websites before they can hurt you.
How it works
- Live threat feed — every site you visit is checked against a continuously updated list of known malicious domains (source: CERT Polska, a trusted national CSIRT).
- Local link inspection — misleading links like
[email protected] are detected and blocked right in your browser, without sending your data anywhere.
- Login & card form protection — fake login pages and fake payment forms are flagged instantly.
- Warning mode — choose between a full warning page or a subtle badge, whichever suits you.
Privacy
Scam Guard protects your privacy as much as it protects your device. The threat feed is downloaded to your browser and all checks happen locally on your device. Your browsing history never leaves your computer.
