Mailvelope vs Proofpoint Email DLP and Encryption

Mailvelope adds client-side end-to-end PGP encryption to supported webmail. Its browser add-on works with Gmail, Outlook, WEB.DE, and other webmailers, and can encrypt or decrypt attachments within email, including with PGP/MIME. While composing, it can detect a recipient’s public key; signature mismatches can help identify phishing attempts. Users can export keys, manage multiple keyrings, and use Mailvelope or other key servers. The free private-user offering is independent from Google, but lacks PGP/MIME, Google Workspace integration, and customer service. Mailvelope states that it complies with GDPR and EU privacy laws. Business plans include a 14-day free trial without payment data. Monthly billing costs €3 per user per month; annual billing costs €32.40 per user per year. Paid subscriptions auto-renew and can be cancelled anytime. Business integrations include professional or premium email support options. Mailvelope is available as an extension and through the web.

Proofpoint Email DLP and Encryption detects sensitive information in email and attachments to help prevent data loss and automate compliance. Administrators can apply encryption policies at global, group, and user levels through LDAP and Active Directory integrations. Detection includes hundreds of built-in identifiers and dictionaries, with custom entries supported, and scans more than 300 file types by default. Policies can trigger encryption based on destination, sender, or message attributes; encryption can also act as a TLS fallback. Recipients can access protected messages through a web portal, mobile browser, or Outlook client. A centralized dashboard provides real-time statistics and trends, incident review, and actions on non-compliant messages. Proofpoint says Email DLP integrates with Unified DLP for shared configuration, detection, and remediation across email, cloud, applications, and endpoints. Listed compliance areas include PCI, SOX, GDPR, PII, and HIPAA. The service is available on Android, iOS, web, and Windows, with cloud and hybrid deployment options. Proofpoint states that it uses HTTPS/TLS in transit and AES 256 encryption at rest, and undergoes an annual SOC 2 Type II audit.
