CEO: Patrick Peterson
Founded by a splinter group from Cisco Systems, Palo Alto, Calif.-based Agari strives to protect its customers' brand names from those who might commandeer their domains and use them for spam. The company identifies all domains that send email on the client's behalf, and advises them when a third-party is impersonating their domain. The system also helps clients to publish authorization policies to mail providers to assist with protection and enforcement. The three-year-old company's services are seen by security experts as being instrumental in the reduction of phishing attempts.
