Five reasons to choose CacheGuard

Why choose CacheGuard when there are other web gateways to choose from? Most other companies sell their products separately, one for a firewall, one for an antivirus, one for caching, one for optimizing bandwidth… you get the picture. With CacheGuard, all of these products, and more, are included in one product.
