Content rule templates

Content rules are applied to policy routes to provide specific instructions about what the security policy is looking for, and what to do when it triggers. When you create a content rule, you must select a Content Rule Template on which to base your rule.

Content rules look for conditions that match the What To Look For? clauses and apply the What To Do? actions that have been configured.

Choose your content rule template carefully, as it determines which What To Look For? clauses are included.

You can change the suggested What To Do? actions and add additional actions if required.
