Google announced on Thursday a re-branded Web Security for Enterprise based on the Postini technology it acquired last year.
The Web hosted service protects corporate Web and e-mail users from viruses, spyware, and malicious Web sites, and extends protection directly to remote workers if needed.
The release is part of Google's hosted apps business, but targeted at corporate customers with a subscription fee rather than consumers who have come to expect free apps from Google.
"Securing the current enterprise environment is futile," Philippe Courtot, chief executive of Qualys, which offers security as a service to corporations, said in an interview on Friday. "This is a problem Microsoft should have fixed a long time ago."
With an arsenal of search, Web hosted apps and the advertising-supported "money-making machine ...Google is going to kill Microsoft," he predicted.
Google's offering is compelling for corporations because of the ease with which they can be up and running without any IT headaches, says Nitesh Dhanjani, senior manager and leader of application security services at Ernst & Young.
"Microsoft says 'here's the software.' Google says 'it's already there; we just create the accounts and you can start today,'" Dhanjani says. "We're seeing, from an IT perspective, that in the next couple of years services will move into the cloud, even security services, so Google is really thinking ahead."
However Microsoft also offers security services. The company turned its FrontBridge acquisition into Microsoft Exchange Hosted Services, which includes security. But the software giant doesn't have a pure, software-as-a-service-based messaging security platform like Google or MessageLabs, says Paul Roberts, senior analyst for enterprise security at The 451 Group.
"Microsoft clearly sees the light that the Web and the Internet are the [operating systems] of the future and that selling shrink-wrapped software isn't going to be feasible," Roberts says.
Peter Firstbrook, a program director at Gartner, summed it up this way: "I wouldn't ring the bells yet, but it is another feather in Google's cap; another service they can offer so that they become more strategic to their customers."
