- Refers to a security appliance that delivers all the features of a UTM (unified threat management) solution – firewall, VPN, anti-virus, and intrusion blocking – but with extended security, networking, and management capabilities. The goal of XTM is to create an ever-expandable network security platform.

XTM extensibility also tries to ensure that appliances interoperate and support mixed network infrastructures, giving an administrator a wide array of configuration options.
