Installation
PhishNet is a Chrome extension that installs in about 30 seconds. It uses your existing Google account — no separate PhishNet account required.
Step 1 — Install from the Chrome Web Store
- Open Chrome and visit the PhishNet listing on the Chrome Web Store.
- Click Add to Chrome, then Add extension in the confirmation dialog.
- The PhishNet shield icon appears in your browser toolbar.
Step 2 — Sign in with Google
Click the PhishNet icon and choose Sign in with Google. PhishNet requests the following Gmail permissions:
| Permission | Why it's needed |
|---|---|
| Read your email messages | To analyse the content of emails you open and detect threats |
| Manage your email settings | To move high-risk emails to quarantine when you or your admin enables auto-quarantine |
PhishNet only reads emails you actively open — it does not scan your archive or run in the background without you.
Step 3 — Open any email
Navigate to Gmail and open any email. PhishNet scans it automatically and displays the result in a panel below the email header within a few seconds.
That's it. No configuration required to start protecting your inbox.
