Stop scams before they stop your wallet
One clever link is all it takes. A fake "your parcel is on hold" text, a perfect copy of your bank's login page, a "too good to be true" deal that steals your card. Scam Guard stands between you and all of it — in real time, and completely free.
Every site you open is checked in milliseconds. If a page is a known phishing, scam or malware site, you never see it: a full-page warning blocks the way and tells you exactly why the site is dangerous.
Everything you get — 100% free
Everything is free, forever. No trials, no credit card, no locked features, no plan upgrades.
- 🔛 Real-time site checks — every tab, every redirect, verified against a trusted malicious-domain list before the page can load.
- 🎣 Phishing detection — fake login pages and look-alike domains ("paypaI.com" with a capital I) are caught instantly.
- 💳 Card & password form protection — malicious links, dangerous login forms and fake checkout pages are flagged before you can enter sensitive data.
- 🌍 Trusted intelligence — the threat list comes from CERT Polska, a national computer-security incident response team, refreshed automatically in the background.
- 🤫 Silent when it's safe — sites that pass stay untouched. A discreet green badge is all you'll notice.
- 🎛️ Your choice of style — a full blocking warning page, or a subtle badge for sites the feed rates lower.
- 📋 Plain-language reasons — when something is blocked, you see why: known phishing, scam, malware, or fake payment form.
- 🖥️ Works on every browser you already use — Chrome, Edge, Firefox and Opera. One install, instant protection.
- 🔒 Private by design — all checks happen locally on your device; your browsing history never leaves it.
Set it up in 60 seconds — how to use Scam Guard
- Install it. Choose your browser's button above. Your store handles the rest — no sign-up, no settings to configure.
- Browse like always. There's nothing to remember and nothing to click. Scam Guard quietly checks each site and link against fresh threat intelligence before it can hurt you.
- Trust the shield. The toolbar badge is green when a site is clear. If it ever turns red, a warning page will show you exactly why the site is dangerous.

Your privacy — the whole story
Scam Guard is local-first:
- The threat list downloads to your browser. Site checks happen on your device.
- Your browsing history, visited URLs and clicked links are never sent to us or to anyone else.
- We ask for the narrowest permissions the job allows — nothing more.
- No ads. No trackers. No data selling. There is nothing to upgrade — everything is free.
What's happening under the hood
- A page is about to load → Scam Guard resolves its domain.
- The domain is matched against a local copy of the malicious-domain feed.
- On the page, Scam Guard inspects risky links (like
https://[email protected]) and login or card forms on untrusted origins — all without ever reading what you type.
- Dangerous → bold warning page. Suspicious → badge on the toolbar. Safe → you notice nothing at all.
The threat feed is refreshed automatically in the background, every few hours. You decide how strict to be.
Scam Guard protects against
- Phishing sites — fake logins for banks, email, PayPal, crypto wallets and shops.
- Parcel & invoice scams — "pay a small customs fee", fake invoices and refund scams.
- Tech-support & giveaway scams — scary popups and fake prizes designed to harvest card details.
- Malware & exploit pages — drive-by downloads and exploit kit domains on confirmed lists.
- Fake stores — brand knock-off shops and non-delivery sellers.
