- See the hosting location and Risk Rating of every site you visit (as well as other information).

The Netcraft anti-phishing community is effectively a giant neighbourhood watch scheme, empowering the most alert and most expert members to defend everyone within the community against phishing attacks. Once the first recipients of a phishing mail have reported the target URL, it is blocked for community members as they subsequently access the URL. Widely disseminated attacks (people construct phishing attacks send literally millions of emails in the expectation that some will reach customers of the bank) simply mean that the phishing attack will be reported and blocked sooner.

The Firefox Netcraft Extension explained (Google Chrome version similar)
The Netcraft Extensions also:
- Traps suspicious URLs containing characters which have no common purpose other than to deceive.
- Enforces display of browser navigational controls (toolbar & address bar) in all windows, to defend against pop up windows which attempt to hide the navigational controls (Firefox only).
- Clearly displays sites' hosting location, including country, helping you to evaluate fraudulent urls (e.g. the real citibank.com or barclays.co.uk sites are unlikely to be hosted in the former Soviet Union).
So download and try out the Extension now and protect yourself on the web.
