Google has released software that will allow organisations to control how employees use the internet, protecting them against malware attacks in real time.

According to a blog post by Tim Johnson, product marketing manager, Web Security for Enterprise will also provide tools to help enterprises create and enforce internet policies. An add-on feature extends the same security to remote users by automatically directing all off-network traffic to a scanning infrastructure that enforces policies to protect users' computer, a product that protects organisations against malware attacks in real time.

The product allows organisations to control how employees use the internet, the application is powered by Postini, which Google acquired last year, and uses technology from ScanSafe. It is integrated with Google Apps security and compliance messaging services.

Google Web Security for Enterprise protects against web viruses, spyware and zero-hour threats, Google said, and also protects networks and users from undesirable web content, file types and MIME types, monitors online activity with comprehensive reporting, and reduces bandwidth congestion.

Google Web Security for Enterprise also applies acceptable use policies to remote employees, enhances privacy by automatically encrypting web traffic whenever users connect to public networks, and eliminates the need for users to connect to the network over the corporate VPN.

A Google spokesman said the service costs $36 (£18) a year per user and an additional $12 (£6) per year for each remote user. He said it was a re-branded, less expensive product that had been offered by Postini.
