For some environments, customers may desire multiple anti-virus engines and Outbreak Protection features. ProtectionPlus extends and compliments the built-in features of SecurityGateway Email Spam Firewall for Exchange/SMTP Servers by offering an additional anti-virus engine from Kaspersky Lab and the Recurrent Pattern Detection and Zero-Hour Outbreak Protection of Commtouch.

• Anti-virus protection from Kaspersky Lab combines traditional anti-virus defense methods with the latest proactive technologies.
• Provides solid and dependable protection against viruses and malware (malicious programs).

• Recurrent Pattern Detection (RPD) uses patented technology to identify patterns which are content agnostic to safeguard the original message. These patterns cannot be used to reconstruct the original message.
• RPD extracts and then analyzes relevant patterns, which are used to identify massive email-borne outbreaks. It classifies both distribution and structural patterns within an email message.
• RPD patterns are compared to the local cache which provides fast match results for more than 70% of the patterns. If a pattern is not in the local cache, RPD will query global data centers for a match to provide true real-time protection with the most up-to-date patterns. These global data center queries then update the cache to keep the most current patterns available locally.
• RPD is designed to distinguish between the distribution patterns of solicited bulk emails, representing legitimate business correspondence, from those of unsolicited bulk emails, representing spam.
• RPD identifies incoming threat messages with very few, if any false positives. Not only are the patterns content agnostic, they are also language-independent making it equally effective for all message formats and encoding types.

• Real-time, anti-spam, zero-hour anti-virus, anti-spyware, and anti-phishing technology.
• Capable of proactively protecting your email infrastructure automatically and within minutes of an outbreak.
• Outbreak Protection requires no heuristic rules, content filtering, or signature updates.
• Relies on the analysis of "patterns" associated with an email transmission and compares them to similar patterns collected from billions of email messages sampled daily, in real-time, from live Internet email traffic.
• Resulting analysis can detect outbreaks in "Zero Hour" - much faster than traditional filter and signature based solutions that require detecting, defining, and disseminating new virus information.

These are the minimum recommended system requirements for ProtectionPlus for SecurityGateway to run. This does not take into account running multiple programs simultaneously. To run several programs on the computer at the same time, that computer should exceed these recommendations.

• SecurityGateway email spam firewall for Exchange and SMTP Servers.
• The number of ProtectionPlus user licenses must be equal to (or greater than) the number of user accounts in your SecurityGateway server. Attempts to use a lower ProtectionPlus license size compared to the number of SecurityGateway users will cause ProtectionPlus to cease functioning.
