Exchange Anti-virus and Anti-spam
Today more than 85% of all electronic mail traffic is a waste of time, consisting of spam, malicious threats, or offensive material. Businesses are under siege from increasingly sophisticated networks of criminal hackers, spammers, and phishers. In addition, you now have to manage email communications to protect your intellectual property (IP), be proactive against lawsuits, and ensure compliance with regulatory mandates, like Federal Rules of Civil Procedures (FRCP), State Information Privacy Acts, and the Health Insurance Portability and Accountability Act (HIPAA).
By using Postini, A Better OutlookSM can help protect you and make you more productive without missing that important email or dealing with ever increasing volume of spam.

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