Netcraft Anti-Phishing Extension

Netcraft Anti-Phishing Extension

Netcraft first launched its anti-phishing system in 2005. All phishing sites are carefully validated before an alert is raised. Well over 6 million unique phishing sites have been detected and blocked by Netcraft’s system to date [February 2013].

Netcraft’s phishing feed is used in all major web browsers and it is also licensed by many of the leading anti-virus, content filtering, web-hosting and domain registration companies. At least three separate third-party studies have found Netcraft’s anti-phishing blocklist to be the most comprehensive feed available.

Netcraft has worked with a wide range of security providers. Netcraft provides these services to companies such as Kaspersky, McAfee, Symantec, Trend Micro and Zone Labs amongst others.
