Managed Firewall Services (MFS) provide agencies with a security buffer between their trusted internal networks and non-trusted external networks, through a hardware and/or software solution. The service can be implemented on servers, routers, as standalone firewall hardware, or across a network. Policies can be tailored for specific locations for
premises-based firewalls. The use of network-based firewalls enables agencies to deploy a common set of policies across several locations.
