Firewall & Configuration Review

A firewall and configuration review examines the rule base as it stands, including what is redundant or overly broad, whether segmentation boundaries between zones actually hold, where administrative management interfaces are reachable from, services permitted beyond their intended audience, whether configuration reflects the policy it is meant to enforce, weak defaults and unnecessary features left enabled, how access to the devices themselves is granted, and where configuration could be tightened without breaking operations. Firewall rules are easy to add and hard to remove — every rule was added for a reason that is rarely documented, so policy grows monotonically into broad rules meant to be temporary, paths permitted for systems that no longer exist, and administrative access reachable from more places than anyone intends. Review is performed against configurations you provide for the devices in scope.

Who needs it? Organizations whose rule base has grown to the point where nobody is confident which rules are still needed, organizations where segmentation is claimed on a diagram but the rule base may not reflect it, organizations that carried rules across a migration and never revisited them, and organizations preparing for an audit or review where configuration needs to be demonstrably reasoned about.

How TMG Security helps. TMG Security reviews the rule base, segmentation, administrative access and configuration against the devices you provide, and delivers findings your team can act on.

Every rule was added for a reason. The reason is rarely documented, the person who added it may have moved on, and nobody wants to be responsible for removing the rule that turns out to be load-bearing.

The result is a policy that grows monotonically: broad rules that were meant to be temporary, permitted paths for systems that no longer exist, and administrative access reachable from more places than anyone intends.
