Why Proofpoint
Email Dlp And Encryption
Protect Sensitive Data with Email DLP and Encryption
Detect sensitive data, prevent accidental exposure, and automatically encrypt outbound email to reduce risk and support compliance.
Email Data Loss Prevention
Human error makes email protection essential
Email DLP and encryption solutions help organizations detect, control, and secure sensitive data before it's exposed through email. Automated policies can block, encrypt, quarantine, or flag risky messages to reduce data loss, protect confidential data, and support compliance.
Protect sensitive information
Identify PII, health and financial data, and intellectual property in Microsoft 365 files, PDFs, images, and unstructured content.
Reduce data loss risk
Apply dynamic, granular policy controls in response to sensitive outbound emails and risky user behaviors.
Simplify data protection
Protect external communications automatically with no-touch key management and flexible recipient access options.
Detection and Response
Detect sensitive data before it leaves by email
Proofpoint Email DLP and Encryption identifies sensitive data in email messages and attachments using prebuilt identifiers, custom dictionaries, data classes, detectors, and advanced content analysis. It scans Microsoft 365 files, PDFs, images, and unstructured content to help security teams enforce email DLP policies with fewer false positives.
Granular Data Detection
Identify PII, PHI, PCI, intellectual property, and other regulated data in email messages and attachments.
Flexible Policy Controls
Apply policies based on data type, sender, recipient, destination, and message attributes.
Automated Risk Response
Block, quarantine, route, encrypt, or alert users before sensitive data leaves the organization.
Image and Document Analysis
Interpret images and scanned files to detect sensitive content that traditional tools can miss.
Document Fingerprinting
Match full or partial sensitive documents across multiple file formats.
Centralized Management
Review policy violations, investigate, and act on policy violations from a single dashboard.
Encryption and Enforcement
Automate encryption and policy enforcement
Apply dynamic DLP policies through the Proofpoint email gateway to protect internal and external email communications. Automate encryption based on sender, recipient, destination, message attributes, or attachment type. Support TLS encryption and flexible recipient access without adding complexity.
Policy-Based Encryption
Encrypt email automatically when messages meet sensitive data or policy criteria.
LDAP and Active Directory Integrations
Target rules by group, department, or user to match business requirements.
Trusted Partner Encryption
Enable transparent encryption with trusted partners using compatible gateways.
Secure, Flexible Recipient Access
Let recipients access encrypted email through a web portal or browser.
Outlook Add-Ins
Enable users to send and read encrypted messages directly from their Outlook email client.
Smart Send Workflows
Route policy violations to users or data owners for review and self-remediation.
Unified Platform
Unify email DLP with enterprise data security
Complete your data security strategy with comprehensive coverage for sensitive data across email, cloud, applications, and endpoints. Shared detectors, data classes, and alert workflows help analysts more easily investigate and remediate data loss with consistent policies across channels.
Enterprise DLP

Adaptive Email DLP
Detect and stop misdirected email and risky actions before sensitive data is lost, with integrated behavioral AI.
Insider Threat Management
Identify and prevent risky user activity that can lead to data loss.
Unified DLP Policies
Deploy consistent data loss prevention policies across all channels.
Common Detectors
Reuse data detectors and classes across channels to simplify administration.
Centralized Management
Detect and remediate incidents, manage policy, and accelerate operations from a single interface.

Frequently Asked Questions
Email DLP identifies and controls sensitive data before an email is sent. Email encryption protects the message during delivery and access. Together, they help prevent unauthorized data exposure by detecting sensitive content, enforcing policies, and securing email communications.
Encrypted email providers focus on securing message content during delivery and access. Email DLP goes further by identifying sensitive data before a message is sent and applying actions such as encryption, blocking, quarantine, or user review. Organizations that need to reduce data loss risk, support compliance, and enforce data protection policies often require both email DLP and encryption.
Yes, modern email DLP solutions can inspect email content, attachments, PDFs, Microsoft 365 files, and images. Advanced detection techniques help identify sensitive information even when it appears in unstructured documents or image-based formats.
Email DLP helps reduce the risk of a data breach by identifying sensitive information before it leaves the organization. Policies can automatically block, quarantine, encrypt, or route messages for review when risky content or behavior is detected.
Email DLP helps enforce policies that protect regulated and confidential data. By detecting sensitive information and applying controls before messages are sent, it can support compliance efforts related to regulations such as GDPR, HIPAA, PCI DSS, FINRA, and SOX.
Email DLP protects sensitive data in email, but organizations often need consistent controls across cloud applications, endpoints, collaboration tools, and AI platforms. Integrating email DLP with enterprise data security solutions helps security teams apply policies, investigate incidents, and manage data protection from a unified framework.
