Google has made its first security purchase by snaring start-up GreenBorder Technologies, a provider of virtualised web browsing anti-malware software, for an undisclosed amount.

But industry experts do not believe the deal signals Google is planning to further flex its muscles in the IT security marketplace. Instead, experts told today, the search giant likely will use the purchase to secure its recently unveiled business application suite, not as the kick-off to a portfolio that would compete with the likes of Symantec and McAfee.

"Google dabbles in everything," Mike Rothman, president of analyst firm Security Incite, said. "They’re extremely smart and they kind of dip their toes and learn. If they want to do something, they tend to do a pretty big purchase and write a pretty big cheque. GreenBorder is not that purchase."

GreenBorder announced the deal on its website, only to say that it has been acquired by Google and that it will continue to offer support for existing customers through the end of their subscriptions.

GreenBorder’s anti-malware software creates a "sandboxed" web browsing environment that isolates each internet session from the rest of the computer to prevent malicious code infection.

Several bloggers speculated how the search giant may deliver the GreenBorder technology. The "Windows Tips and Tricks" blog suggests the software "will re-emerge somewhere in a Google application."

Alan Shimel, chief strategy officer for network security provider StillSecure, said Google right now is not interested in competing for security customers.

"I just don’t see them taking on that role with host-based security," he told today. "They are focused on delivering secure online collaboration. They’re not into being a security vendor; they’re into being a secure vendor."

However, given the GreenBorder purchase, the recent launch of the Google Online Security Blog, and a new white paper analysing web-based malware, some believe the search giant is ready to join a trend.

"Security is increasingly becoming a game for the big boys," Shimel wrote on his blog today, "but it is the smaller companies like GreenBorder that fuel innovation."

Google has remained largely mum on the deal, which reportedly closed in mid-May.

"We were impressed by GreenBorder's small team of talented engineers and believe they can help to build products and features that will benefit our users, advertisers and publishers," a Google spokesperson said in an email to
