Catch every possible case of structural rule redundancies

SolarWinds Firewall Security Manager maximizes your opportunity for cleanup by catching every possible case of redundancy that can accumulate over time (the main reason a rule base becomes bloated and overly complicated). Structural redundancies represent errors in the configuration that play no role in the firewall's behavior and can be immediately removed for gaining an instant boost to rule base efficiency. Examples of redundancies include:


  • Generalized rules that cover a number of more specific rules already existing in the firewall
  • Rules that are added without realizing that together, one or more rules preceding or succeeding the new rule already handle the functionality being addressed by the new rule
  • Rules that are added as a special case of one or more subsequent rules to exhibit special behavior (often temporarily)

Find stale rules based on rule hit counts and traffic data captured in the firewall logs

SolarWinds Firewall Security Manager will find stale rules based on rule hit counts and traffic data captured in the firewall logs. This is useful to remove temporary rules and rules that are no longer needed because the business purpose for the rule went away. Examples include:


  • ACL rules that were never used in the given log period. You can remove entire ACL rules using this report.
  • Network and Service objects that are not used in a rule. You can narrow each rule for which usage is available using this report.
  • Members of Network and Service object groups that are not used in any rule. You can remove entire objects and in some cases narrow the definition of object groups by removing unused members using this report.
  • Most used rules and objects for the given log period
