What is Email DLP (Data Loss Prevention)?
DLP, or data loss prevention, is an umbrella term for activities and technologies that prevent the loss, accidental disclosure, or unauthorized access of sensitive information. Email DLP is a subset technique of data loss prevention, which describes techniques aimed at stopping data loss caused through email.
Types of Email Data Loss to look out for
The three main types of data loss are:
- Accidental Data Loss
- Malicious Data Loss
- Data Exfiltration
Accidental Data Loss, as the name implies, involves data being lost accidentally. When it comes to accidental data loss through email, common and frequent examples include employees unknowingly sharing information with the wrong people within the organization or using “Reply All” instead of “Reply” and distributing data with a larger group than intended.
While accidental data loss happens unintentionally, malicious data loss is a targeted act, in which individuals with access to confidential or sensitive information purposefully aim to harm an organization. Examples for malicious data loss include individuals sharing confidential information outside the organization, forwarding sensitive data to a personal or external address, or making copies of confidential information to an external device.
Examples of attacks with the goal of data exfiltration include common cyberattacks such as Business Email Compromise (BEC) , Ransomware Attacks, and Spear Phishing amongst others.
Superior email DLP tools help protect your organization
Data leakage prevention for email (email DLP) has become a critical technology for organizations. Sensitive information related to customer, financials, future business plans, and new products is routinely kept in digital form and shared by employees through email. When these assets are leaked inadvertently or intentionally, the cost can be quite high – from fines and legal actions to damage to reputation and loss of business.
The right email DLP solution can help prevent leaks and protect your organization, but choosing the right data leak prevention tools is essential. Your email DLP technology must be comprehensive enough to stop leaks anywhere in the organization and flexible enough to not stifle productivity. On top of that, your email DLP solution must not add additional administrative burden to IT teams already facing constrained budgets and staff resources. Mimecast offers a cloud-based data leakage protection service that combines easy-to-use tools with powerful technology to protect your organization by stopping email leaks.

Mimecast's email data loss prevention service synchronizes with Secure Active Directory and provides flexible content policy management features that make it easy to apply appropriate controls to specific users and groups. Mimecast scans all email – including body text, headers, subject lines, HTML, and attachments – and compares content against policies that identify specific words, text patterns, and images as potential data leaks. When a policy is triggered, administrators may choose from a variety of possible actions including hold pending review, block, CC a group, deliver securely, or add content. Mimecast also enables hidden metadata from Microsoft Word documents to be removed to help reduce the risk of unintentional leaks. Administrators can manage policies from a single web-based console, applying changes consistently to all sites and every mail server in real time. Policy-based TLS encryption protects against eavesdropping when emails are in-transit, helping to meet compliance and corporate governance requirements. Encryption may be applied on a mandatory or case-by-case basis. And the Mimecast Secure Messaging service enables users to share sensitive information with people outside the organization without content ever leaving the security of the Mimecast network.How Mimecast's email data loss prevention solution works
