Encryption rule priorities

The following set of rules defines the resulting state on the client if more than one policy is applied to the same location.
  • If two rules are equal regarding Path and Scope, the standard SafeGuard policy prioritization scheme is used.
  • If two rules come from policies that are assigned to different nodes, the rule from the policy nearest to the user object in Users & Computers will be implemented.
  • If two rules come from policies that are assigned to the same node, the rule from the policy with the highest priority will be implemented.
  • Rules with mode "Ignore" will be evaluated before rules with mode Encrypt or Exclude.
  • Rules with mode "Exclude" will be evaluated before rules with mode Encrypt.
  • Rules with the "Include Subdirectories" flag enabled will be evaluated before those with the flag disabled.
  • Rules with a path with more subdirectories will be evaluated before paths with less subdirectories.
  • Rules defined as UNC (Uniform Naming Convention) will be evaluated before rules given with drive letter information.
  • Absolute rules (e.g. "c:\encrypt") will always be evaluated before relative rules (e.g. "encrypt").
  • If two rules are equal regarding the above criteria, the one that comes lexically first will be evaluated before the other rule.
