Why do you need DLP for email? ^Microsoft provides several security mechanisms to protect data in email. However, DLP will help you further secure your data by allowing you to define policies based on regulatory requirements. For instance, you can block outgoing email that contains US credit card numbers, social security numbers, and other financial data. There are also templates to block email with private or medical information. See this link for a detailed list of available templates. In addition, you can create custom policies that contain many more confidential and sensitive data types that can be blocked. Many organizations might want to shield data to be compliant with the mandatory rules or laws, such as GDPR, set by regulatory bodies. DLP proves immensely useful in handling such scenarios. Once you have the end goal in place, you can use the policies to reach that target.
