With self-hosted ACS, you or your partners are responsible for installing, securing, and maintaining the software, including the operating system, database, backups, and upgrades, on your own systems. VigorACS 3 Cloud offers the same management and SD-WAN features, but it runs on DrayTek-managed Google Cloud servers. HQ and regional partners handle platform maintenance, so you can focus on setting up your devices and building your network.
