Unified Threat Management (UTM) refers to a comprehensive security solution that integrates multiple security features and services into a single platform. It combines various tools such as firewalls, antivirus, intrusion detection/prevention systems (IDS/IPS), content filtering, and VPN support to provide centralized protection against a wide range of cyber threats. UTM solutions are designed to simplify security management, reduce costs, and enhance overall network security by offering a unified approach to threat detection, prevention, and response.
