What is a Unified Threat Management (UTM) appliance?
Fri, 07 May 2021
A unified threat management system, or UTM security appliance, can at a fair cost provide a robust and easily controlled security solution for small and medium-sized organizations.
UTM appliances offer an alternative approach to the construction of a security system from multiple point items, mostly from different vendors. Such point solutions operate independently of each other to fulfill the various protection functions needed by an organization and may include a hardware firewall module, an anti-malware scanner, and a network intrusion detection and prevention device.
What is Unified Threat Management?
A unified threat management (UTM) system is a type of network hardware, virtual appliance, or cloud service that incorporates and integrates various security services and features to protect businesses from security threats in a simplified way.
UTM devices are also marketed as network security tools and can help defend networks against combined security threats, malware, and attacks that target different parts of the network simultaneously.
UTM cloud services and virtual network appliances are increasingly common for network protection, especially for small and medium-sized enterprises. These remove the need for on-site network security tools, but also have centralized control and user-friendliness for deep network security protection building.
How UTM works?

UTM products are also marketed as network protection tools that can help protect the networks from combined security threats, including ransomware and attacks that threaten different parts of the network simultaneously.

UTM security features
A UTM security appliance serves as a normal, standard network hardware firewall on the network to limit access to the network at the most basic level. Certain security features can usually be turned on as options if available. Typical security features the UTM security app offers to include:
Remote access and Site-to-Site Virtual Private Network (VPN) support Secure Web Gateway capabilities including anti-malware scanning and URL and content filtering.
A network intrusion prevention program that focuses on blocking attacks against unpatched Windows PCs and servers
Other UTM protection features that are often offered:
Application control
Web application firewalling
Bandwidth management
Data loss prevention (DLP)
Identity-based access control
Load balancing
DDoS protection
Wireless access management
Email security
Pros of UTM:
Fewer resources needed:
A UTM needs minimal security personnel as there is only one mechanism for managing, updating, upgrading and monitoring through a single glass pane. Security logs are available in one location, too.
Better security of safety:
A UTM does not leave any gaps in the security it offers since all components should be built to work together. This is not always the case for a variety of point solutions.
Scalability:
Because a UTM is a single tool, the protection solution can be updated (or replaced) more easily as the company expands.
Lower cost:
A UTM is typically less costly than other point solutions that run on separate hardware. A UTM will, therefore, use less power and take up fewer data center space, and because it operates in a single device, it will require less expense of replacing hardware.
Backup security:
A UTM security system can be purchased to serve as a hardware firewall only, with point solutions offering other security functions. The benefit of this strategy is that if a particular point solution fails, then the corresponding feature can be disabled as a stop-gap protection mechanism in the UTM before the point solution can be re-run again. A comparison of UTM firewalls is required to decide which UTMs are providing firewalls that are sophisticated enough to act as a standalone firewall appliance.
