Patent 10021133 was granted and assigned to CipherCloud on July, 2018 by the United States Patent and Trademark Office.
A system and method for detecting a phishing site is disclosed. A message from a client to the site is intercepted by a security gateway. The security gateway determines if the site is a known-site or an unknown-site. If it is a known site, a reputation of the site is checked. If the site is a known-site with a bad reputation, connection between the client and the site is reset. If the site is a known-site with a good reputation, known-site testing is performed for possible phishing attack. If the site is an unknown-site, unknown-site testing for possible phishing attack is performed.
