UTM - Unified Threat Management

Combines several security functions in a single device.

UTM appliances generally support a firewall, VPN (Virtual Private Network), anti-virus, anti-malware, and URL filtering functionality.

In deciding whether to deploy a single comprehensive UTM device or several appliances, you need to consider:

Security capabilities of dedicated devices are usually more robust and more reliable.
Since a UTM is handling multiple functions simultaneously, this can lead to a significant processing load in high traffic situations, depending on the design.
With all the security functions in a single device, this becomes a significant single point of failure in your security posture. Running UTMs in a duplicated, high-availability mode reduces this risk.

Consider UTMs from the following suppliers:

Juniper: Juniper offers a broad product portfolio, spanning routing, switching, security, application acceleration, identity policy and control, and management, designed to give customers unmatched performance, greater choice and flexibility while reducing overall total cost of ownership.
Check Point: Check Point Software Technologies is the worldwide leader in securing the Internet, and is the only vendor to deliver Total Security for networks, data and end points, unified under a single management framework.
