dlp email security for Data Protection

Data Protection laws require organizations to implement robust email security measures to safeguard sensitive information. This includes encrypting emails to prevent unauthorized access.

To meet these requirements, DLP (Data Loss Prevention) email security solutions can automatically encrypt emails containing sensitive data. This ensures that even if an email is intercepted, the contents remain protected.

DLP email security solutions can also flag suspicious emails containing sensitive data, allowing administrators to review and take action. This helps prevent data breaches and ensures compliance with Data Protection regulations.

Email security solutions are crucial for protecting sensitive data from unauthorized access. Mimecast's email data loss prevention solution synchronizes with Secure Active Directory and scans all email content, including body text, headers, and attachments, to identify potential data leaks.

Policy-based TLS encryption protects emails in-transit and meets compliance and corporate governance requirements. Administrators can manage policies from a single web-based console, applying changes consistently to all sites and every mail server in real-time.

Email DLP solutions like Forcepoint DLP for Email deliver industry-leading control over outbound emails and prevent exfiltration. They can be easily deployed on major email providers like Microsoft Exchange and Gmail for Business, and policies can be configured and published in less than five minutes.

Email DLP solutions combine a range of functions and technologies to protect organizations from leaks and breaches. They typically examine messages in real time, intercept suspicious emails, and enforce rules that align with corporate and compliance mandates.

Core features of email DLP solutions include analyzing incoming and outgoing email content, including attachments and subject lines, to detect the presence of sensitive information such as personally identifiable information (PII) or financial details.

Key technologies powering email DLP tools include pattern matching, keyword analysis, and AI and machine learning. Pattern matching identifies sequences of sensitive data, while keyword analysis checks for red-flag terms or context-specific words indicative of private information.

Here are some common enforcement controls used by email DLP solutions:

These controls ensure that sensitive data is protected and only accessible to authorized users.

To ensure your business stays secure, it's essential to monitor for three main types of email data loss: accidental, malicious insider, and mailbox breach.

Accidental data loss can happen in a split second, often due to human error, such as attaching the wrong file to an email or sending sensitive data to the wrong recipient.

In the worst-case scenario, an authorized employee may intentionally share confidential information with an external party, which is known as a malicious insider threat.

Cybercriminals may gain access to your company's email accounts using various tactics, including phishing scams, compromised devices, or stolen credentials, leading to a mailbox breach.

Here are the three types of business email data loss to monitor:

Granular privacy controls are a crucial aspect of email data loss prevention (DLP). They ensure that sensitive information is protected by limiting access to only authorized personnel.

Flexible access controls are implemented to guarantee that analysts only see data on a need-to-know basis. This means that they have limited visibility into sensitive content, which reduces the risk of unauthorized access.
