McAfee, Inc. today announced that it is making the Internet safer for all users by completing the acquisition of privately held ScanAlert, Inc. ScanAlert is the creator of the HACKER SAFE web site security certification service, which protects over 50 million e-commerce transactions per month and proactively advises consumers about which sites are safe for shopping. The ScanAlert technology will be integrated into McAfee’s award-winning safe search and surf technology, SiteAdvisor(R), which just reached a significant milestone of its own: It has been downloaded more than 100 million times by consumers who request SiteAdvisor’s Web site ratings more than a billion times each day.
