Unified threat management (UTM) is an umbrella term for a hardware or software platform that integrates multiple security functions. The term peaked in popularity a couple of years ago. These days, vendors call their products UTM, NGFW (next generation firewall), and several other labels. 

UTM became particularly popular in the small and mid-sized enterprise market as it saved them having to evaluate, purchase, deploy, and train personnel on multiple best-of-breed tools. It also saved on the money side as choosing one security platform tended to come with a nice discount.  

The offerings vary considerably from vendor to vendor based on their existing product strengths, partnerships, acquisitions, and development roadmaps. Most include firewalls, intrusion prevention/detection systems (IPS/IDS), and secure gateways. Often, they also deal with remote access, routing, WAN connectivity, threat intelligence, and more. But it all depends on the vendor, what it has in its security arsenal, and what it can cobble together via acquisitions.

Key Features of UTM 

A Gartner analysis of UTM tools noted the following features in use, as well as their frequency: 

  • Firewall (100%)
  • URL filtering (77%)
  • IPS (70%)
  • Web antivirus (51%)
  • IPsec (63%) 
  • SSL, application control and virtual private networking (VPN) (46%)
  • User control, QoS, and anti-spam (41%)

As you can see, there is plenty of room for variation in this market. 

UTM Buying Tips 

Here are some tips to help in product evaluation and selection: 

  • As each vendor incorporates different tools in their software suites or UTM appliances, buyers should start with the features they need and then match UTM products up against those specific features. 
  • The evolving threat landscape means firewalls and UTM products need to do more than ever before. As well as core functions above, ask about how the prospective vendor is incorporating new tools to stop complex, evolving attacks, how their tools can share threat intelligence with other security systems to automatically identify and isolate infected machines, and how they are incorporating analytics. 
  • Investigate the degree of integration. Some tools are highly integrated. Others are just packages tied loosely together that really only integrate on the front end. 
  • A feature that is growing in importance is to be able to parse the mountain of information collected, correlate data with other systems, and highlight critical information or threats that require action. But not all vendors offer this. If it is important to you, insist vendors demonstrate that such functionality is available now, not merely promised on a nebulous roadmap.

Top UTM Vendors

Enterprise Networking Planet considered multiple vendors. Here are our top picks for UTM, in no particular order: 

Sophos Firewall

Sophos logoSophos Firewall combines the features of firewalls and UTM to offer network security with insights into network activity. It provides visibility into risky users, unwanted applications, suspicious payloads, and persistent threats. It integrates a suite of threat protection technologies that are easy to set up and maintain. And the Sophos Firewall communicates with other security systems on the network, enabling it to become an enforcement point to contain threats and block malware from spreading or exfiltrating data out of the network.

Key Differentiators

  • Sophos Firewall includes full-featured email anti-spam, encryption, and DLP along with a web application firewall. 
  • It integrates with various VPN technologies to enable remote workers to securely connect with applications and data.
  • Visibility into risky activity, suspicious traffic, and advanced threats.
  • Deep learning and intrusion prevention to keep networks secure.
  • Automatically identifies and isolates compromised systems to stop threats from spreading.

Fortinet NGFW

Fortinet_LogoFortinet offers a range of UTM products as part of its FortiGate and FortiCloud lines. These appliances provide high-performance, multi-layered security, and unified visibility while reducing complexity. They leverage dedicated security processors and provide wireless access point controller, switch controller, integration, software-defined wide area network (SD-WAN), NGFW, IPS, anti-virus, Web filtering, content filtering, DLP, VPN tunnel endpoint (SSL and IPSec), SSL inspection, and advanced threat protection capabilities. 

Key Differentiators

  • Next-generation firewalls (NGFWs) filter network traffic to protect from internal and external threats. 
  • Deep content inspection to identify attacks, malware, and other threats. 
  • SSL inspection, application control, intrusion prevention, and visibility across the attack surface. 
  • FortiGate Next-generation Firewalls are powered by purpose-built security processing units (SPUs), including the latest NP7 (Network Processor 7). 
  • Inspection of traffic at hyperscale as it enters and leaves the network. 
  • FortiGate NGFWs can communicate within the Fortinet security portfolio as well as third-party security solutions in a multivendor environment. 

Cisco Meraki NGFW

Cisco Meraki’s layer 7 next-generation firewall, included in Cisco MX security appliances, gives administrators control over the users, content, and applications on their network. The Cisco Meraki proprietary packet processing engine analyzes network traffic up to and including layer 7, using fingerprinting to identify users, content, and applications. Each network flow is categorized and access control policies are enforced. 

Key Differentiators 

  • By classifying traffic at layer 7, it controls evasive, encrypted, and peer-to-peer applications, like BitTorrent or Skype, that cannot be controlled by traditional firewalls. 
  • Cisco Meraki’s next generation firewall is included in all wireless access points and security appliances.
  • Integrated IDS/IPS engine based on Sourcefire Snort.
  • Using a combination of signature, protocol and anomaly based inspection methods ensures network security. 
  • Device-aware access controls enable administrators to ensure the appropriate level of network access for each class of devices. 

WatchGuard UTM

watchguard logoWatchGuard UTM encompasses a stateful packet firewall backed by an array of scanning engines to protect against spyware and viruses, malicious apps, and data leakage. There are many aspects to the company’s UTM offerings.
