Download CacheGuard Patches

To upgrade your already installed CacheGuard-OS you can either download CacheGuard-OS latest version and reinstall your appliance or apply a patch. Please note that we do not always provide a patch to upgrade as some major evolutions require a reinstallation from scratch. But you do not need to worry: the configuration of a CacheGuard UTM & QoS can be saved in a file and reloaded into a freshly installed CacheGuard-OS. For upgradeable versions you can find patches on CacheGuard Network at CacheGuard Patches.
