How does Unified Threat Management Work?



Unified threat management (UTM) offers a high level of network security that is close to complete. Next-Generation Firewalls (NGFWs), Intrusion Detection and Prevention (IPSs), secure web and email gateways, remote access, and Vast Area Network (WAN) connection are all examples of UTM devices.

The growth of Unified Threat Management appliances has led to blended threats, which integrate many types of malware and attacks. To remain on top of the latest malware and cybercrime, you will have to update and manage each component separately. It is necessary, especially if you use several appliances and vendors for different areas of business protection. Since UTM systems provide a single point of defense and a single console, they make dealing with threats more accessible.

Cons include the fact that a UTM device provides just one point of defense, which means that it also creates alone vulnerability. A software-based perimeter is often added as a supplement to the UTM device to prevent malware from evading the firewall.
