What is Managed Firewall?
A managed firewall is a type of network security that provides protection against unauthorized access to your computer networks and systems. It does this by filtering traffic and blocking incoming connections that are not authorized. A managed firewall can be either hardware- or software-based and is typically deployed as a part of a larger security system.
Advantages of Managed Firewalls
There are several advantages to using a managed firewall:
Improved Security: By blocking unauthorized traffic and connections, a managed firewall can help improve the overall security of your network.
Peace of Mind: With a managed firewall in place, you can have peace of mind knowing that your network is better protected against potential threats.
Cost Savings: In many cases, a managed firewall can actually save you money by reducing the need for other security measures (such as anti-virus software).
Disadvantages of Managed Firewalls
There are also some disadvantages to using a managed firewall:
Initial Cost: Depending on the features and level of protection you require, a managed firewall can be quite expensive.
Complexity: Managed firewalls can be complex to configure and manage, especially for larger networks. This can often lead to increased IT costs.
Impact on Performance: Because a managed firewall filters traffic and connections, it can sometimes have an impact on network performance. This is usually negligible, but in some cases, it can be significant.
Can Firewalls be Managed Remotely?
Yes, most managed firewalls can be remotely managed. This allows you to centrally manage and monitor your firewall from a single location. Remote management typically requires an additional fee, but it can be worth it for the added convenience and flexibility it provides.
How do Firewalls Manage incoming and outgoing Traffic?
Firewalls typically use a set of rules to determine what traffic is allowed and what is blocked. These rules can be based on various criteria, such as the source or destination of the traffic, the type of traffic, or the port being used. By configuring these rules, you can control exactly how your firewall behaves.
What are the Managed Firewall Services?
Managed firewall services typically include all of the following:
Installation and Configuration: The provider will install and configure the firewall according to your needs.
Monitoring and Maintenance: The provider will continuously monitor the firewall for any potential issues and perform necessary maintenance and updates.
Reporting: The provider will generate regular reports that show you how the firewall is performing and whether any changes need to be made.
Support: The provider will offer support in case you have any questions or problems with the firewall.
Some of the leading managed firewall service providers include Cisco, SonicWALL, and WatchGuard.
