306 billion—that is the average number of emails sent and received around the world in a single day. This number shows how common and indispensable emails are in daily communication. Needless to say, a sizable amount of information is carried through emails everyday. Although email makes communication remarkably convenient, there is a fair share of risk associated with sending data through emails, as unknown parties can interfere and steal this data.
Email security continues to be a challenge for IT admins around the globe. When shared via email between sources, personally identifiable information (PII) including bank details, legal documents, medical records, and other critical information belonging to organizations poses a high risk of data leakage. Email encryption alone does not suffice, as it does not take human error into consideration.
ManageEngine Endpoint DLP Plus is powerful software that employs email data loss prevention (DLP) features to prevent sensitive data from leaving your organization via unauthorized emails. It helps you avoid data breaches through email and reinforce email security in your organization. All elements of an email are monitored for sensitive data, and policies can be applied to restrict their transfer.
Endpoint DLP Plus keeps your data from falling into the wrong hands by securing email communication. The Email DLP feature regulates unauthorized access to emails and achieves email security for Outlook through the following steps:
Email DLP uses predefined templates and data classification techniques such as fingerprinting, keyword search, and RegEx to identify emails containing PII or other restricted data specific to an industry. The various fields of an email such as the sender, subject, BCC, CC, attachments, and more are scanned and filtered for confidential data.
Once sensitive emails are identified, the Email DLP feature lets you configure policies to monitor and control how these emails are transported. Create policies to block the transfer of these emails by default and override the decision after the email is verified. These policies can be created in accordance with your organization's security regulations and can significantly reduce the risk of unintentional data leakage by employees.
To ensure that sensitive data stays within the organization, you can include all company-specific domains in a whitelist. This provides a safe space for authorized employees within the organization to communicate freely. Enterprise approved email domains can be whitelisted so that data leaving the organization is being received only by an approved senders list belonging to trusted users or organizations.
Implementing DLP for email in your organization helps in staying compliant with security standards such as PCI DSS, HIPAA, and the GDPR, as it identifies and regulates the movement of sensitive information.
Email DLP is implemented by providing three degrees of permissions in compliance with the needs of the organization.
Audit only - All files are allowed to be transferred via email but each instance and file access is logged and archived.
Allow within trusted domains - Transfer of files from a trusted list of users/web domains are permitted.
Block emails with sensitive content/ attachments - Emails containing sensitive information are not allowed to be transferred irrespective of the destination or recipient. However, an option is given to override the policy if the user deems it necessary and provides an appropriate business justification for the same.
