Ninja Email Security is an advanced and powerful, policy-based email security product that provides you as a system administrator the weapon to enforce email policies that protect your network against spam, phishing, viruses and other messaging security threats.

Ninja provides a layered security approach for email inspection, cleansing and management. By using multiple scanning engines for antispam and antivirus, while integrating other email security rules, all treatment of messages occurs at the server, not at your end-users' workstations - no client software needed.
