Because Google security and compliance, powered by Postini, handles billions of connections every day, we are constantly developing the latest, highly accurate intelligence on what is happening on the internet. When we block a virus from one sender, we alert the entire network. So your protection stays ahead of the "bad guys." This "network effect" makes Google’s protection more efficient than any firewalls or anti-spam software can be. This is possible with an expansive, multi-tenant operations capability that only Google can offer.

The Postini Real-time Evaluation and Message Processing Technology, or PREEMPT™, provides five layers of protection against all email-borne threats. Backed by a 100% anti-virus service level agreement, PREEMPT includes the following components:

• Postini Threat Identification Network® (PTIN) technology to block connections from malicious internet protocol (IP) addresses
• Signature-based anti-virus scans with signature updates checked every 60 seconds
• Anti-virus heuristics that monitor current virus activity and help predict the likelihood of future attacks
• Statistical analysis and evaluation of message components for level of threat
• Proactive checks on attachments to block or quarantine specific file types including compressed files

The Postini Threat Identification Network blocks messages coming from specific IP addresses based on observed, malicious behavior. This means that your company is protected as soon as a new threat is detected anywhere on the network. Because the blocks are based on real-time IP traffic analysis, your protection does not need to wait for spam, virus, or worm signatures.

This allows Postini to block attacks at the network layer to give you the best protection from threats, coupled with the highest performance and scalability.

The Postini Anti-Spam Engine (PASE) is a heuristic framework, developed by Postini to analyze the content of messages and learn as spammers present new threats. PASE can block emerging threats, such as image spam and other day-one attacks, because it has learned to identify these new threats before they can cause damage. It can also address a variety of traffic such as web, and supports your policies by taking the appropriate actions based on your unique settings by user, group, and company.

High-performance characteristics and multi-lingual capability make it ideal for global deployments.
