How does Mimecast’s Data Leak Prevention (DLP) work?

Mimecast’s Data Leak Prevention (DLP) works by scanning outbound emails for sensitive information to prevent accidental data breaches. This proactive approach involves analyzing the content of emails sent from within the organization, looking for patterns or data types that match predefined rules corresponding to sensitive information. This can include personally identifiable information (PII), financial data, intellectual property, and other types of confidential content.

By implementing DLP in this manner, Mimecast helps organizations mitigate the risks associated with unintentional data exposure. If an email is found to contain sensitive information, Mimecast can apply various actions based on the organization's policies, such as blocking the email, alerting the sender, or requiring additional approvals before sending.

This functionality is essential for compliance with regulatory requirements and for maintaining the confidentiality and integrity of valuable business information. It places a significant emphasis on security, allowing organizations to maintain control over their data in a digital landscape prone to threats and breaches.
