Google buys Postini for $625 million

Continuing in its quest for trying to beat Microsoft in the office category, Google made another big buy, buying a 'communications security' firm, Postini, for $625 million. What does Positini do ? Well, it lets corporations set security rules for all communication happening inside the company, such as e-mail, instant messenger and browsing activities. Such policies are necessary for companies, be it to maintain a track of communications for legal purposes, to filter e-mail for spam and viruses, or to prevent employees from accessing certain type of information.

When corporations adopt Postini's software, they can access, filter and impose restrictions on their employees' e-mail, instant messaging and Web habits. And because Google's moving into corporations -- it's fighting Microsoft for the right to rule over our cubicles -- helping firms keep an eye on their workers is an important goal.
There's a useful purpose to these corporate lockdowns, of course. Google notes that companies are under regulations to preserve all their data; the SEC is going to want to know if you discussed setting up Cayman Island shell corporations over AIM. So companies that are itching to use Google's office apps -- Gmail, Google documents, Google Talk, etc. -- can't switch over until the software can be made to obey such archiving rules. Companies are also targets of espionage, they're subject to leaks, and they suffer losses due to viruses and other network attacks. By keeping workers' computers pinned down and monitored, Postini can mitigate all these risks, it says.

Postini is not meant for the employee, it is meant for the corporations to better enforce policies. This acquisition by Google will help make Google's apps (such as Google Pack, Google Talk, etc) be more usable in an office context, and give them a realistic chance of competing with Microsoft's products, Google's prime goal.
