The enterprise browser management tool called Catalyst reached public availability yesterday. The program gives corporate IT departments the ability to force specific Web sites to open in different browsers.

As CNET reported in November, it's a useful workaround for businesses that still use Web apps that only work in legacy browsers but want their employees to spend the rest of their browsing time on more modern, more secure browsers.

Browsium noted in its blog announcing the stable version of Catalyst that it can also be used to minimize security issues, such as the recent Java and Internet Explorer zero-day exploits, by locking down which browsers can open.

Browsium CEO Gary Schare wrote in an e-mail to CNET that the security issue could be a big driver in Catalyst adoption. Google Apps, he wrote, are dropping support for Internet Explorer 8 and below, which will force companies to use Chrome or Firefox and use multiple browsers if they use legacy apps designed for IE, too. "Many of our early prospects are Google Apps customers," he wrote, although he wouldn't reveal yet which companies those are.

Catalyst is available for a 30-day free evaluation, and then costs $20 per seat. Schare said that discounts would be available for large volume deployments.
