Managed firewall service providers handle the implementation and maintenance of firewall infrastructure. Instead of IT teams deploying the firewall internally, it is provided as a service.

Services are an area of the cybersecurity market that has been growing in recent years, as they represent an easy route to more sophisticated cyber protection. Unfortunately, security services have also gotten mired in marketing and terminology complexity, making purchasing decisions difficult for those buyers most in need of simplicity.

Vendor offerings have gotten so complex that at times it is hard to even find if there is a firewall service buried under all the other features. Gone are simple firewall offerings. Those disappeared a few years back when next-generation firewall (NGFW) became the preferred term. Vendors offered NGFWs that were firewalls plus many other features, and those feature sets varied depending on the vendor.

Now the term NGFW itself has disappeared. By decoupling the firewall from an appliance and moving it to the cloud (some vendors still retain the appliance on site), the latest terminology is Secure Access Service Edge (SASE). Under that banner, service providers are offering a great many security products, including firewall-as-a-Service (FWaaS), that are bundled together and aimed at ever-expanding network boundaries. Think Internet of Things (IoT) and mobile devices, remote workers, branch offices, partners, customers and more. It can be more than a little challenging for buyers with a more traditional network to defend.

Those looking for managed firewall or FWaaS offerings usually find themselves evaluating much broader offerings. Therefore, a direct conversation with vendors is recommended to find out what they offer. Otherwise, managed service providers (MSPs) and their customers may be paying for a lot more services than they need.

What is a Managed Firewall Service?

Let’s get back to basics. A managed firewall is a service delivered by an external provider of managed security services who provides firewall configuration, administration, monitoring, report generation, support, and sometimes on-site installation.

Sometimes the firewalls are software only, sometimes they are a combination of hardware and software, with an appliance installed on-site. It is up to the MSP to take care of the function and maintenance of the firewall. The MSP also provides alerts, feedback, reports, and may use the firewall at times for analysis. Other services may be included such as application control and web content filtering.

Do I Need a Managed Firewall?

Installing and configuring a firewall can be complex, depending on the environment, the requirements of the customer, and the ever-changing cybersecurity landscape. It is vital that the firewall be configured properly to not only protect an organization’s network but also to avoid interrupting business activities by accidentally blocking traffic that should be allowed through. Such skills are not always easy to come by. Training technicians in every nuance of firewall operation can be time-consuming and expensive, especially in cases where turnover in technical staff is happening every few months.

But another big reason why more people are opting to have their firewalls managed externally is their desire to have someone monitor firewalls 24×7, as hackers can strike at any time and only so many companies have round-the-clock security staff.

“Having this continuous monitoring enables the organization to detect and respond to threats before they can cause significant harm,” said Christopher Crellin, Senior Director, Product Management, Barracuda MSP. “Ultimately, having a managed firewall service ensures that the firewalls are properly configured and monitored so the business doesn’t have to worry as much about in-depth training.”

The Top Managed Firewalls

Channel Insider reviewed the many managed firewall services available on the market. Most of these are available to MSPs who wish to rebrand them or sell them to their existing customers. Here, then, are our picks for the best managed firewalls.
