Managed firewall

What is a managed firewall?

In the context of Defense in Depth, a firewall is the first step to creating a secure IT environment. A firewall is used to block traffic coming into your IT network as well as traffic going out. Within the simple security model of PROTECT - DETECT - RESPOND, a firewall protects. A firewall's primary function is to provide protection at the perimeter of your network.

It's All About the Configuration

In the course of doing business, your firewall must be configured to allow certain traffic in and out, for example, to support email and your company website. This configuration is accomplished through the creation of rules specific to your environment.

The best firewall in the world won't help you if it's not configured correctly.


Or if it was configured correctly at one time but needs to be reconfigured because your IT environment has since changed, and the firewall rules were not modified.

A managed security service provider (MSSP) manages your firewall for you, making sure the software is up to date and that the correct configuration changes are made as your network evolves.


What is a managed firewall?

A managed firewall service provides robust security protection for your network that is managed by an outside cybersecurity firm and billed at a flat monthly fee. This service provides a business with ongoing 24x7x365 real-time monitoring and protection of the IT infrastructure.



Why not manage the firewall ourselves?

When you use a managed firewall service provider, your firewall is actively managed and configured properly. A properly configured firewall can prevent attacks from occurring.

Also, with a managed firewall service, you may be getting a more feature-rich next generation firewall than you might normally set up for yourself. Typically, companies will install a firewall and configure it, then maybe never touch it again for years. Whereas with a managed firewall solution, you are more likely to have a top-of-the-line firewall solution. Plus, the firewall is being monitored 24x7x365 by your managed services provider’s cybersecurity engineers.

The latest firewall solutions include advanced analysis engines that analyze communication streams as they flow through the firewall. The best solutions deliver excellent perimeter security and control at throughput speeds that keep up with traffic of your network, at the edge and core.
