Benchmarks provide standardized configuration guidelines, such as those from CIS, enabling the MSSP to create consistent firewall configuration templates and apply changes efficiently across multiple clients.

A firewall is a technical control enforced by hardware or software to monitor and filter network traffic, distinguishing it from physical (e.g., fence, security guard) or administrative (e.g., policy) controls.

A firewall cluster increases reliability by providing high availability and failover between multiple firewall instances. If one firewall fails, another can take over processing traffic, ensuring continuous connectivity at the primary data center.
