Zone Labs simplifies personal-firewall management

Simplified firewall management

The management console runs on a browser, so you don’t need to work from the server itself (although you can if you wish). You control major functions by clicking on the left side of the screen to reveal a detailed menu on the right side. The screens controlling each feature are well designed and easy to follow, but because of Integrity's flexibility you will find you have a lot of choices to sort through.

Once running, Integrity provides plenty of feedback. You can examine the operations of the enterprise as a whole, with charts and graphical reports; look at groups; and even monitor the operations of a single client computer. If you have an urgent need to make a policy change, for example to combat the potential arrival of a new worm, you can push policy changes to the clients in the enterprise.

We were impressed by Integrity 2.0, but it wasn't all a bed of roses. The most significant issue is that Integrity only supports Windows. If you have a heterogeneous enterprise, you’ll have to find something else to handle the personal-firewall needs of your Linux, Macintosh, and Unix computers, which will add more complexity than you may want.

We also found that the Integrity client slows down the process of browsing for another computer on a Microsoft network, even when access to that computer is allowed. This seems to be restricted to browsing Microsoft shares, but it may not matter to you, as many enterprises already disable this feature of Windows.

Whether Zone Labs Integrity 2.0 is for you depends on your enterprise. But we found it to be a well-executed, well-designed solution for companies that need internal firewall protection, and we’re inclined to believe that this applies to nearly every company. It’s easy to install, deploy, and administer, and it provides solid protection. And because it ties the personal firewalls of all of your Windows clients to one management point, it greatly eases the work for your network administrators. We just wish it supported more than just Windows.
