Postini's Integrated Message Management platform features multiple layers of protection and the latest technologies from industry leaders to provide up-to-date protection from all email IM and Web threats. Postini processes more than one billion messages per day, providing real-time visibility into threats distributed across the Internet and around the globe. Postini also processes and delivers more encrypted messages per day than any other system, protecting confidential and sensitive messages for more than 35,000 clients around the world.

Spam and Spim Blocking
Postini Integrated Message Management stops nearly all email spam, as well as unwanted IM messages (spim), with virtually no false positives. Postini's industry experts continually fine-tune filters to combat the latest spam and spim tactics, requiring no effort from corporate administrators. This improves both user satisfaction and productivity as well as decreasing administrative costs.

Virus and IM Worm Blocking
Postini Integrated Message Management provides superior protection against viruses, worms and other malicious content using patented Postini technology coupled with redundant, multi-layered filtering technologies from industry leaders McAfee, Authentium, and Symantec. Hosts exhibiting malicious behavior are blocked in real-time. Virus and worm signatures are updated every sixty seconds. Postini's unique, multi-layered approach, backed by the industries leading service-level agreement, ensures that threats are blocked from both corporate networks and mobile users.

Anti-Phishing and Fraud Protection
Postini Integrated Message Management protects the enterprise from fraud and intellectual property leakage by applying sophisticated intelligence targeted specifically at phishing — the act of soliciting proprietary information via email, IM or the Web. Postini's unique multi-channel approach to anti-phishing and fraud protection blocks inbound attacks over email and instant messaging coupled with outbound protection by blocking Web access to malicious Internet sites. This greatly reduces corporate exposure to fraud and theft.

Real-Time Attack Blocking
Postini Integrated Message Management blocks directory harvest, denial of service, and other debilitating attacks, before they reach corporate networks. Postini's patented Sender Behavior Analysis™ technology detects attacks at connection time and immediately blocks source IP addresses — not just for the Postini client being attacked, but for all Postini clients. Thus Postini clients benefits from the massive amount of traffic — more than one billion messages per day — processed by Postini's systems. Postini's real-time attack blocking dramatically reduces infrastructure costs and improves corporate messaging performance costs by blocking nearly 85% of traffic as malicious or unwanted before it ever reaches enterprise networks.

Policy-Based Encryption
Postini Integrated Message Management greatly allows enterprises to exchange secure communications with anyone, regardless of their encryption capabilities. Businesses can enforce secure connections with trusted partners using the Transport Layer Security (TLS) messaging standard as well as enforcing encryption of messages with recipients whose encryption support is unknown or doesn't even exist. Administrators can tailor policies for specific users and messages may also be filtered for spam, viruses, and content compliance. Postini's policy-based encryption makes it affordable and easy to support secure messaging between the enterprise and a wide variety of constituents such as business partners, contractors, regulators, remote employees and even clients.
