A managed firewall is a service provided by third-party vendors that involves the outsourcing of the setup, administration, monitoring, and maintenance of an organization’s firewall configurations. Essentially, it’s a firewall as a service (FWaaS) where the complexity of firewall management is taken care of by experts, so businesses can focus on their core competencies. Here are some features and benefits of a managed firewall:

  1. Setup and Configuration: The service provider will handle the initial setup and configuration of the firewall, ensuring it’s tailored to the specific needs and architecture of the organization.
  2. 24/7 Monitoring: Managed firewalls come with continuous monitoring. This means any suspicious activities or threats are detected in real-time, and timely action can be taken.
  3. Updates and Patches: Service providers ensure that firewall firmware and software are regularly updated with the latest patches, protecting against new vulnerabilities and threats.
  4. Expertise: Companies get the benefit of expert knowledge without having to employ a full-time specialist. This is especially beneficial for small and medium-sized enterprises (SMEs) which might not have the resources for an in-house cybersecurity team.
  5. Policy Management: The managed firewall provider will help define, implement, and maintain access control policies, ensuring only authorized traffic can access the network.
  6. Reporting: Regular reports on firewall performance, detected threats, and other metrics are provided. This gives businesses insights into their network security posture.
  7. Scalability: As an organization grows, its firewall needs might change. Managed firewall services often offer scalability options to handle increased traffic or more complex network architectures.
  8. Cost-Effective: Outsourcing firewall management can be more cost-effective than managing it in-house, especially when considering the costs of hardware, software, and personnel training.
  9. Backup and Redundancy: Many managed firewall providers offer backup services to ensure configurations are saved and can be quickly restored in case of failures.
  10. Incident Response: In the event of a security breach or incident, the managed firewall provider will often have a dedicated team ready to respond, helping to mitigate damages and restore services.
  11. Compliance: For businesses that need to adhere to specific regulatory standards (like PCI DSS, HIPAA, or GDPR), many managed firewall services ensure that firewall configurations and policies are compliant.
  12. VPN Support: Many managed firewall providers offer support for setting up and maintaining Virtual Private Networks (VPNs) for secure remote access.

It’s essential for organizations considering a managed firewall service to do their research. This includes understanding the service level agreement (SLA), the provider’s reputation and expertise, and ensuring the service aligns with the organization’s specific needs and budget.
