Postini is a company acquired by the super search giant Google on July 9, 2007, the San Carlos, Ca based firm being supposed to bring more security inside Googleplex. Today, Postini makes a major step to reach this goal by enhancing its Email Security service with new email content policy management features. First of all, the technology now provides protection for credit card information and for social security numbers, two functions which could reduce the amount of leaked information outside a company. Besides these utilities, Postini also improved the Email Security and Message Archiving technologies with some brand new functions such as zero hour detection capabilities or advanced message archive management tools.

"Companies of all sizes are seeking to reduce email security and compliance risk. They are seeking to encrypt email communications automatically based on message content, prevent sensitive content from leaving the company via email and have visibility into policy violations," said Scott Petry, founder of Postini and director of product management at Google.

"Postini's innovation in content analysis and disposition simplifies the process of managing communications compliance policies for our customers. We are continuing to deliver on the promise of SaaS (software as a service) as the most cost and time effective way for large and small enterprises to manage their communications."

Postini efforts are especially supposed to protect users against the threats distributed by the Internet, including spam, phishing, viruses and other types of malicious content which is able to harm users' computers. Google already introduced Postini technologies inside its own Google Apps in a move meant to bring more protection for the companies looking to implement numerous utilities such as Gmail, Google Calendar, Docs & Spreadsheets and some others into their offering.
