Data Loss Prevention policy

Data Loss Prevention (DLP) stops data from being leaked by email.

In email Data Loss Prevention policies you add rules to restrict the information that can be included in emails. Rules can be applied to inbound or outbound emails and you can add up to 25 rules to a policy.

You can apply rules to different users, groups of users and domains. For example, you could set up a rule to prevent any financial information going out of the organization for most users. You could then apply a less strict rule to accounting staff.

To add Data Loss Prevention to emails, create a Data Loss Prevention policy.

When you create a policy, the action is set to the Sophos default. You can change this when you create or edit the rule.

In Settings, you can see the rules for inbound or outbound emails that are associated with a policy. You can change the order of the rules, and turn them on or off. To view or edit rule settings, click on the rule name. You can also create new rules for a Data Loss Prevention policy.

When you create a rule you can use templates provided by Sophos to protect your data. You can also customize rules. You can choose the action you want to take when sensitive information is found in an email.
