About rule-based decryption policies
Rule-based decryption policies
Decryption policy you create using a wizard that steps you through the available options for inbound decryption, outbound decryption, or both. After you create the rule-based decryption policy, you can add more rules to it, reorder rules, or make other changes to suit your needs.
A rule-based decryption policy is the most flexible but also the most potentially complicated. You can convert a standard decryption policy to a rule-based policy at any time.
