Defend against cybercrime
The browser extension protects you against a wide range of malicious attacks. Avoid accidentally visiting sites we’ve classified as malicious. You can report new ones to us directly from the extension interface.
Easily configure what level of protection you desire by enabling/disabling different attack types in the extension options.
Risk Rating
Check at a glance whether a site is likely to contain malicious content. We evaluate the characteristics of the site and compare these against those common amongst fraudulent sites. This is beneficial for new sites which may have not yet been blocked by us.
Site Report
Get easy and quick access to a detailed report about the site, helping you to make informed choices about their integrity. This includes information such as:
- Country: The country where the site is hosted
- First seen: The first Netcraft Web Server Survey this site was seen in
- Site rank: The popularity of the site amongst Netcraft extension users.
- Host: The name of the organisation hosting the site
- PFS: Check if sites using SSL for encryption support Perfect Forward Secrecy (PFS). PFS ensures that if the private key of the site is compromised - for example by a court order, social engineering, an attack against the site, or cryptanalysis - your historical encrypted traffic remains safe.
