The browser extension for Chrome

Stops fake sites and rushed payments in Chrome.

The HARD extension stops lookalike and phishing sites before they load, catches your password on the wrong site, pauses big payments and checks every extension you install. It all runs in your browser.

HARD for Chrome and BraveVersion 1.0.0, released 6 November 2026

In Google’s reviewGoogle reads every extension before it’s listed, which usually takes a week or two.

One email when it’s ready for you, in the store or with an early access place. Nothing else.

What it sees
The pages you open, read in your browser to find fake sites, sign-in forms and payment buttons
What it sends
Never the pages you visit or what you type. Only an address that already looks suspicious goes to rdap.org, to see when it was registered.
Works in
Chrome, Brave, Opera, Vivaldi and Arc, and Edge from the same store. Firefox and Safari are coming.
The HARD extension stopping a fake PayPal page before it loads: the “a” in paypal.com is from another alphabet, with a button to go to the real PayPal

What it does

Fake sites, stopped before they load

Addresses that imitate a real one, like a letter from another alphabet or a bank’s name on someone else’s domain. Sites on a public list of reported phishing, refreshed every 12 hours. And suspicious addresses registered in the last few weeks.

What it stops

Copied sign-in pages

A Google, Microsoft or Apple sign-in form on a site those companies don’t own is stopped, even when the address looks fine.

How HARD spots a copy

Your password on the wrong site

HARD keeps a salted one-way hash of the passwords it watches, never the password. Type one into any other site and it clears the field and stops the form.

Your passwords

A pause before big payments

On banks, payment apps and crypto exchanges, a big payment, a new payee or a crypto address waits while HARD asks the questions scammers hope you won’t. If AnyDesk, TeamViewer or Quick Assist is open beside your bank, HARD says so.

The payment pause

Every extension checked

Known-malicious extensions, ones installed from outside the store, and ones that can read your cookies or control your browser.

The panel

With HARD for Mac

The extension tells HARD for Mac what it stopped, so your protection is in one place. It sends the site’s name and what HARD did, never what you typed or the page.

With HARD for Mac
The HARD extension stopping nab-secure-verify.com, a site using NAB’s name, with one click back to the real bank The extension’s panel: stopped 4 fake sites today, with each one and why, and a paused payment on CommBank

The extension guide covers the panel, the payment pause and every setting.

Check it’s really HARD

Scammers copy security extensions. A real copy of HARD comes from the Chrome Web Store, published by Flindev, and its ID is always the same. You don’t have to take our word for it.

  1. Open this address in your browser, and press Details under HARD:

    chrome://extensions

    The address bar now ends in the extension’s ID. A real copy’s ID is cjombajfggahaccmdjmlfhcbibpnlcho. In Brave it’s brave://extensions, and the ID is the same.

  2. Check the version there against every version we’ve released.

  3. If the ID doesn’t match, or it came from anywhere but the store, remove it and tell us where it came from. HARD never sends the extension by email or message, only a link to this page.

Installing it

Press Add to Chrome on HARD’s store page, then pin it to the toolbar, from the puzzle piece, so its panel is one click away. Your browser keeps it up to date.

Brave, Vivaldi and Arc install it from the same store page. Opera needs its Install Chrome Extensions add-on first, and Edge needs one switch turned on. Firefox and Safari are coming. If you have HARD for Mac, open it once and the extension’s warnings show up there too.
