A Managed Firewall is a type of network security service that is monitored and managed by a third-party service provider. The provider configures, monitors, and maintains the firewall to ensure that it provides the necessary protection for the network. Managed firewalls are commonly used by organizations that don’t have the resources or expertise to manage their own firewall in-house, or that want to outsource the security management responsibilities to a trusted provider. The provider uses tools and techniques to proactively identify and prevent security threats and ensure the firewall remains effective without customer responsibility. Managed Firewall services are also known as Cloud Managed Firewall, Managed Network Security Service, or Managed IT Security.
