What is a Managed Firewall: Enhancing Network Security

As technology advances, so do the risks associated with online security. Small and medium-sized business owners are increasingly becoming targets for cyber attacks, making network security a top priority. However, not all businesses have the luxury of an in-house IT team to manage their security needs. This is where a managed firewall can make a significant difference. In this article, we will delve into the world of managed firewalls, discussing their benefits and how they can effectively safeguard your business against potential threats.

What Is a Managed Firewall?

A managed firewall is a network security solution that is designed to protect a business’s network from unauthorized access and potential cyber threats. It acts as a barrier between the internal network and the external internet, monitoring and controlling incoming and outgoing network traffic.

A third-party provider or managed service provider (MSP) takes care of a managed firewall as opposed to conventional firewalls, which need manual configuration and monitoring. This means that the responsibility of managing and maintaining the firewall is outsourced, allowing businesses to focus on their core operations without the need for an in-house IT team.

A managed firewall offers several benefits, including continuous monitoring, regular updates and patches, threat detection and prevention, and expert support. Knowing that a dedicated team of professionals is protecting their network gives small and medium-sized business owners peace of mind.

What is the Difference Between Managed and Unmanaged Firewalls?

The main difference between managed and unmanaged firewalls lies in the level of responsibility and control over the firewall’s configuration, monitoring, and maintenance.

A managed firewall is handled by a third-party service provider or managed service provider (MSP). With a managed firewall, the service provider takes care of the firewall’s setup, configuration, monitoring, and ongoing maintenance. They are responsible for ensuring that the firewall is up-to-date with the latest security patches, managing rule sets, and providing support and troubleshooting. Managed firewalls offer businesses the convenience of outsourcing their network security needs to experts, allowing them to focus on their core operations without the need for an in-house IT team.

An unmanaged firewall, on the other hand, requires the business or organization to handle all aspects of the firewall’s configuration, monitoring, and maintenance. This includes setting up the firewall, defining rule sets, monitoring network traffic, applying security updates, and addressing any issues or vulnerabilities that may arise. Unmanaged firewalls provide businesses with more control and flexibility over their network security but require the necessary expertise and resources to manage and maintain the firewall effectively.

The choice between a managed and unmanaged firewall depends on factors such as the size and complexity of the network, the availability of in-house IT resources, and the level of control and convenience desired. Managed firewalls are often preferred by small and medium-sized businesses that lack the resources or expertise to manage their firewall effectively. Unmanaged firewalls may be more suitable for larger organizations with dedicated IT teams who have the knowledge and resources to handle firewall management internally.

How Does a Managed Firewall Work?

A managed firewall works by implementing a set of rules and policies to control network traffic and protect the network from unauthorized access and potential threats. Here is a breakdown of how a managed firewall operates:

  1. Traffic Monitoring: The managed firewall continuously monitors incoming and outgoing network traffic. It inspects packets of data and analyzes their source, destination, and content.
  2. Rule-Based Filtering: Based on predefined rules and policies, the firewall determines whether to allow or block specific types of traffic. These rules can be customized to meet the specific security needs of the business.
  3. Access Control: The firewall enforces access control by allowing or denying access to certain network resources, such as applications, websites, or specific IP addresses. This helps prevent unauthorized access and protects sensitive data.
  4. Intrusion Detection and Prevention: The managed firewall employs intrusion detection and prevention systems (IDPS) to identify and block malicious activities or suspicious behavior. It can detect and prevent various types of attacks, such as malware, viruses, and unauthorized access attempts.
  5. VPN and Remote Access: Many managed firewalls offer virtual private network (VPN) capabilities, allowing secure remote access to the network. This is especially useful for businesses with remote employees or multiple office locations.
  6. Logging and Reporting: The firewall logs and records network activity, providing detailed reports on traffic patterns, security incidents, and potential threats. This information helps in analyzing and improving network security.
  7. Regular Updates and Maintenance: The managed firewall is regularly updated with the latest security patches and firmware upgrades to ensure optimal protection against emerging threats. Typically, the managed service providers are in charge of handling these updates.

By combining these functionalities, a managed firewall provides comprehensive network security, protecting the business’s data, applications, and infrastructure from potential cyber threats. Knowing that professionals in the field are keeping an eye on and protecting their network gives businesses peace of mind.

What are the Different Types of Managed Firewalls?

There are several different types of managed firewalls available, each with its unique features and capabilities. Here are some of the common types of managed firewalls:

Hardware Firewalls

Hardware firewalls are physical devices that are dedicated to network security. They are typically installed at the network perimeter and provide robust protection against external threats. Hardware firewalls offer high performance and scalability, making them suitable for larger networks.

Software Firewalls

Software firewalls are firewall solutions that are installed on individual devices, such as servers, computers, and workstations. They are protected at the device level and can be customized based on specific security requirements. Software firewalls are commonly used in smaller networks or for individual devices.

Cloud Firewalls

Cloud firewalls are firewall solutions that are hosted and managed in the cloud. They provide network security for cloud-based applications and services. Cloud firewalls offer scalability, flexibility, and centralized management, making them ideal for businesses with distributed or cloud-based infrastructures.

Virtual Firewalls

Virtual firewalls, also known as virtualized firewalls, are software-based firewalls that run on virtual machines or virtualized environments. They provide network security within virtualized environments, such as data centers or cloud platforms. Virtual firewalls offer the benefits of scalability, agility, and cost-effectiveness.

Next-Generation Firewalls (NGFW)

Next-generation firewalls combine traditional firewall functionalities with advanced security features, such as intrusion prevention, application control, and deep packet inspection. NGFWs provide enhanced visibility and control over network traffic, allowing businesses to protect against sophisticated threats and manage application-level policies.

Unified Threat Management (UTM) Firewalls

UTM firewalls integrate multiple security features into a single device, including firewalling, intrusion detection and prevention, antivirus, web filtering, and virtual private networking (VPN). UTM firewalls offer comprehensive security solutions for small and medium-sized businesses, simplifying management and reducing costs.

When choosing a managed firewall, it is important to consider the specific needs and requirements of your business. Factors such as network size, complexity, budget, and desired security features should be taken into account. Working with a managed service provider can help you select the most suitable type of managed firewall for your business and ensure that it is properly configured and maintained for optimal network security.

How Much Does a Managed Firewall Cost?

The cost of a managed firewall can vary depending on factors such as the size and complexity of your network, the specific features and capabilities required, and the service provider you choose. Typically, managed firewalls involve ongoing subscription or service fees, which can be based on factors like the number of users or devices, network traffic volume, and the level of support provided. Additionally, there may be one-time costs for hardware appliances, software licenses, and implementation/setup. Ongoing support and maintenance services are often included, but the level of support and response time for issue resolution can impact the overall cost. Some providers may offer additional features or add-ons at an extra cost. It is important to carefully evaluate the pricing structures and compare quotes from different providers to ensure that the cost aligns with your budget and meets your network security needs.


In conclusion, a managed firewall is a crucial component of network security for small and medium-sized businesses. It provides robust protection against unauthorized access and potential cyber threats, allowing business owners to focus on their core operations without the need for an in-house IT team. By outsourcing the management and maintenance of the firewall to a trusted service provider, businesses can benefit from continuous monitoring, regular updates, and expert support. However, it is important to carefully evaluate the specific needs and requirements of your business, as well as the potential risks and costs associated with a managed firewall.
