IT security faces a wide variety of threats every day – from different kinds of malware infecting endpoints and servers to coordinated attacks against entire networks.
Each kind of threat to the IT system requires a particular solution and strategy. This usually forces companies to invest heavily in protecting their vulnerabilities – the more and more varied the number of vulnerabilities, the greater the investment in security.
Not all companies can afford the cost of protecting all their cyber security flanks (you can check out our cybersecurity checklist for more information). As a result, many companies adopt the (wrong) strategy of protecting themselves as far as the budget allows. And, consciously or unconsciously, they leave vulnerable areas exposed to very dangerous threats.
The Solution: Unified Threat Management (UTM)
Unified Threat Management, or UTM, traditionally offered a solution for organizations that don’t have the resources – knowledge, people, money, etc. – required to protect all their vulnerable areas. UTM provides a single point of protection against all known types of threats: malware (viruses, worms, spyware, etc.) and network attacks (denial of service, phishing, SQL injection, etc.).

Combining performance, security, and compliance capabilities in a single installation greatly facilitates security management for network administrators, thereby lowering the costs of keeping a company’s IT infrastructure protected.
FortiGate NGFW
FortiGate is an NGFW that contains all the capabilities of a UTM since it offers features such as content filtering, antivirus, email filtering, web filtering, and email control. It is a highly recommended product for organizations that meet the condition of being a small or medium-sized company that runs high risks or handles very critical data and needs to carry out a deep scan of every packet that traverses its network boundaries.

The FortiGate firewall features highly efficient security processors that optimize network performance while protecting the network from cyber-attacks. It is capable of operating in transparent mode or NAT/Route mode. In transparent mode, the firewall is installed between the internal network and the router, so no network changes are required, except for providing the device with a management IP address.
Transparent mode is mainly used when it is necessary to increase network protection, but changing the network configuration is not a viable alternative. In NAT/Route mode, the FortiGate unit is installed as a gateway or router between two networks. This allows the NGFW to hide the IP addresses of the private network through network address translation (NAT).
While FortiGate is a suitable solution for small companies without dedicated IT security staff, its CLI commands are complicated and not ideal for beginners.

In conclusion, for users looking for a simple and effective UTM solution that brings together what is needed to protect networks for organizations that do not have large IT security budgets, Sophos UTM is a good choice.
Cisco Firepower NGFW
Cisco NGFW firewalls offer advanced threat defense capabilities to meet various needs, from small or branch offices to high-performance data centers and service providers. These appliances are available in a wide range of models, including virtual versions – called Firepower NGFW – available for cloud infrastructures.
The advanced threat defense capabilities of the Cisco NGFWs include next-generation IPS (NGIPS), security intelligence (SI), advanced malware protection (AMP), URL filtering, application visibility and control (AVC), and flexible VPN capabilities. The encrypted traffic inspection offered by Cisco in its NGFWs automatically classifies risks, quickly prioritizing threats and reducing the volume of logged events.
The configuration flexibility of these devices allows them to be deployed in clusters that achieve higher performance along with high availability and scalability (both up and down). Integration with Cisco Defense Orchestrator (CDO) unifies the management of physical and virtual firewalls, reducing the need for administration resources.
The costs of Firepower NGFW appliances are high relative to UTM solutions for more constrained environments. However, those who use them in industries that handle highly sensitive information, where a security breach can cost millions of dollars, claim their prices are a bargain.
SonicWall TZ NGFW
SonicWall TZ small form factor next-generation firewalls are designed specifically for the needs of enterprise and midsize businesses, providing them with an enterprise-class security solution that avoids the complexities usually associated with such solutions. SonicWall TZs act as layer seven security appliances focused on preventing all types of cyberattacks by offering advanced features such as application control, web filtering, and advanced routing.
SonicWall TZs offer easy installation and configuration, and once it is up and running, it provides simplified and centralized management. Thanks to its cloud-based Capture Advanced Threat Protection (ATP) sandbox service, SonicWall’s NGFWs can detect sophisticated threats such as encrypted attacks.
They add optional features such as PoE/PoE+ and 802.11ac Wi-Fi support, providing unified security for wired and wireless networks.
Some users of the SonicWall TZ NGFWs argue that not all features work as they should or have side effects or undocumented functionality, forcing them to spend a lot of time resolving issues that should be simpler.
However, they point out that they minimize the time required for extensive security policy deployment. Their diagnostic tools (packet capture, packet response, application flow reporting, etc.) make it much easier to troubleshoot security issues.
Barracuda CloudGen
Barracuda CloudGen is the cornerstone of the company’s Total Threat Protection framework. CloudGen UTM offers simplified administration through a web interface and free cloud-based centralized management.

Juniper SRX
Juniper’s SRX appliances provide a high-performance network security solution for large-scale ISPs needing advanced routing and security features. It includes all the features of an NGFW, such as deep packet scanning and IPS. Due to its cost and configuration complexity, it is not suitable for smaller companies that do not have specific resources to manage the security of their infrastructures.
The company offers its NGFWs as physical or virtual appliances, both alternatives being suitable to support active or stand-by configurations when they are part of a high-availability infrastructure. Its users highlight its ability to cope with virtually any situation to which it is subjected, from fulfilling basic router functions for branch offices to stateful firewalls capable of monitoring the complete status of active network connections.
To further extend their performance as edge gateways, Juniper SRX UTMs support advanced features of the Border Gateway Protocol (BGP), which enables peering and the exchange of routing information between autonomous systems. As for their administration and configuration tools, the graphical user interface (GUI) is rather basic, while the CLI is very easy to use and much appreciated by users.
Check Point UTM Appliances
Check Point UTM appliances serve small and remote branch office deployments, offering comprehensive threat prevention and high flexibility in terms of both network connectivity and port density. To repel threats, they offer a firewall, IPS, IPsec VPN, antivirus/spam/bots, URL filtering, application control, and email security functionality.
Check Point UTMs’ Threat Prevention technology allows them to “look inside” SSL and TLS tunnels to detect threats even in encrypted transmissions, ensuring that users comply with corporate security policies while surfing the Internet and using corporate data.
To its menu of UTM features, Check Point appliances add a sandboxing scheme called SandBlast Zero-Day Protection, which provides an innovative solution to thwart unknown malware, zero-day attacks, and targeted attacks.
SandBlast uses a new detection technology that operates at the CPU level and can identify threats before the malware deploys its attack. In turn, the SandBlast threat emulation engine monitors the CPU instruction stream for exploits that attempt to bypass the operating system and hardware security controls.
And that concludes this list of the best UTM solutions for your business. It’s also important to know about the distinction between UTM and NGFW, especially if you haven’t used these solutions before.
Basically, over time, UTM solutions evolved to transcend the limits of small companies with small pockets. And large companies began to see them as exciting options to reduce their budgets. This is how the acronym NGFW (next-generation firewall) came about, which is nothing more than a UTM solution but presented as something more adequate for corporate networks.
What is the Difference Between UTM and NGFW?
In practice, there is no substantial difference between a UTM and an NGFW. The technologies used in both are essentially the same. UTM devices are often classified with lower performance ratings than their NGFW counterparts, but for practical purposes, the differences are mainly in the marketing messages.
A set of vendors coined the term NGFW to define a class of products that contained all the features of a UTM but could be inserted into an enterprise network.
The reason for giving these devices a different name was to move away from the belief that a device capable of bringing together all the features of a UTM would never reach the performance standards of enterprise networks. However, as the hardware evolved, the ability of these devices to achieve multi-gigabit speeds began to prove that they were indeed suitable for large enterprises.
A Solution for Every Need
Whether you run a small business with no specialized IT security staff, or you are in charge of protecting a large company’s networks from the many threats that lurk around, the list of UTM products we have compiled here is sure to provide the right choice for your needs.
