Detection services collect information from thousands of decoy e-mail accounts spread across the web and screen them for phishing attempts. When a phishing attempt is detected, the customer is notified so that they can immediately take preventative action, sometimes contacting their own customers to warn them of the fraud attempt. Anti-phishing service providers can also notify major ISPs so that messages from the phishing source can be blocked from the mailboxes of millions of potential victims, along with other kinds of spam.
