Unified Threat Management Firewall (UTM) is an acronym for Unified Threat Management Firewall. A firewall is network security tool that can be hardware-based or software-based and protects against a variety of threats. Firewalls are based on a set of rules that are followed. It compares all input and output data packets to those in the database to determine whether they are potentially harmful. If not, they are permitted to proceed. If this is the case, the firewall will block these data packets.

Firewalls are frequently installed on standalone systems; each personal computer running Microsoft Windows Vista or higher has a firewall installed. The majority of these firewalls are software-based and are used to safeguard against the public internet. Several routers are also equipped with firewalls, which are used to provide security. On the other hand, various other hardware-based firewalls are also capable of performing routine operations. Small networks are mostly served by firewalls.

The use of a firewall is essential for cybersecurity it concerns

·         The security of a network or

·         The security of a system

·         The protection of data for any people or business.

The greatest firewall nowadays is the Next Generation Firewall (NGFW), which helps with security. Meanwhile, there’s the Unified Threat Management (UTM) appliance, which serves many purposes. Many users, particularly NGFW and UTM, have a habit of using these two terms interchangeably. Today, we’ll look at the functions of these two, as well as the differences between them. Let’s compare and contrast Unified Threat Management with Firewall.

 

What is the function of a firewall?

The firewall scans outgoing and incoming data packets for unsuitable or hazardous content before permitting or stopping the data packet.

NGFWs, which are either hardware-based or software-based, go a little further than typical firewall programmes. In addition to filtering and blocking data packets, NGFWs perform a range of other tasks.

These capabilities include application awareness,  active directory LDAP identification, stateful inspection, and a fully integrated intrusion prevention system, among others. You can choose between bridged and routed modes when using NGFWs.

The UTM device and its functions

UTM appliances, unlike NGFWs, are always hardware and have both benefits and cons. Let’s start with the positives, because at HackerCombat, we believe in focusing on the benefits rather than the drawbacks.

Gateway anti-spam, network load balancing, network IDS and IPS (Intrusion detection and prevention system), appliance reporting, URL filtering, gateway antivirus protection, content filtering, email security, web application firewalls, VPN termination, wireless security, DDOS mitigation, and more are all features of UTM appliances. In the case of UTM technology, all data is centralised and can be examined holistically. As a result, users will have a better, real-time picture of threat detection.

So, those are the advantages; now, let’s have a look at the disadvantages. The fact that a UTM appliance can only function if it is connected to the main network is a small disadvantage.

 

Difference between UTM and Firewall

The UTM appliance clearly fulfils all of the NGFW’s functions while also offering additional services. (As a result, it’s probable that many people, even security experts, use the terms interchangeably.) It’s not just about the features; the UTM and firewall are both reasonably priced. As a result, decisions about whether to utilise should be based on the circumstances. If you need the additional services provided by the UTM, you can pick between the NGFW and the UTF software because the NGFW has built-in capabilities within the UTM. Make certain you’re aware of any potential cyber-threats.

Firewalls are supposed to be a barrier between devices that restricts access. The way people talk about hardware, network firewalls, and security appliances in general has evolved over time. Firewalls, proxy firewalls, Next Generation Firewalls (NGFW), and Unified Threat Managers (UTM) are all terms that are used interchangeably nowadays.

As the threat landscape changed, so did the security measures in place to counteract it. When people talk about a firewall, they usually mean one of two things:

  1. A Next-Generation Firewall (NGFW)
  2. A Unified Threat Management appliance (UTM).

The disparity between these two is mind-boggling. NGFWs are a significant improvement over traditional packet filtering firewalls. Denial of Service prevention, stateful packet inspection, deep packet inspection, and a variety of other connection-oriented precautions are all included in most. Many gateway security appliances also have extra features. Many people still refer to these devices as firewalls, although they are much more. This new class of equipment is known as a Unified Threat Management or Unified Threat Gateway appliance, depending on the vendor (UTM or UTG). UTM is now the most popular buzzword.
