Understand DLP policy deployment and simulation mode

Rushing a data loss prevention (DLP) deployment can lead to unintended consequences, such as blocking legitimate actions or generating false positives. This can frustrate users and lead to policy avoidance, which ultimately makes sensitive data less safe. Taking an incremental approach to deployment helps mitigate these risks while allowing you to collect data, tune the policy, and foster smoother adoption across the organization.

Three axes of DLP deployment management

When you deploy a DLP policy, three main factors need to be considered:

• State of the policy
• Scope of the policy
• Actions taken by the policy

Understanding how these factors work together is essential for deploying DLP policies that meet your security goals without disrupting productivity.

State of the policy

DLP policies can be set to different states depending on where they are in the deployment process. The state determines whether the policy is active, inactive, or running in simulation mode.

• Keep it off: The policy is inactive, and no data is monitored or actions taken. This state is useful when you’re still configuring or reviewing the policy.
• Run the policy in simulation mode: The policy monitors activity and records violations without enforcing any actions, allowing you to evaluate the policy’s effects without disrupting user workflows.
• Run the policy in simulation mode with policy tips: In addition to monitoring activity, this mode shows users warnings or tips when their actions would trigger the policy. It educates users on risky behaviors without blocking them.
• Turn it on right away: The policy is fully enforced, meaning all configured actions, like blocking or alerting, are applied.

Scope of the policy

The scope defines where the policy applies. You start by choosing locations like Exchange, SharePoint, Teams, or devices. By default, the policy covers all instances in that location. You can then include or exclude specific instances, like certain sites, users, or groups.

In simulation mode, you can test the policy without enforcing it, which lets you try out different scope settings. Before fully deploying the policy, you can apply it to a smaller pilot group to get feedback. Once you’re ready, you can apply the policy across all the locations you selected.
