Unified Threat Management (UTM) refers to all-in-one security appliances with a number of security features as standard features, including bandwidth management, firewall, VPN, gateway anti-virus, gateway anti-spam, intrusion prevention, content filtering, and centralized reporting.
The UTM includes a tailored OS that houses all the security capabilities in one location, which can result in higher throughput and integration than a collection of unrelated devices.
The ability to update all security functions simultaneously, ease of use, and simplicity are the key benefits of UTM solutions.
