Lockbin vs Proofpoint Email DLP and Encryption

Lockbin is a web application for sending private email messages and files. Recipients can open a message using a unique URL and password; passwordless secure links are also available for known recipients. Messages use TLS in transit and FIPS 140-2 verified AES-256 encryption at rest. Decryption keys are held by the sender and recipient rather than stored in plaintext on Lockbin servers. It works in Chrome, Firefox, Safari, or Edge without a download or installation, and is listed for Linux, macOS, web, and Windows. Lockbin works alongside Google Workspace and Microsoft 365 without a plugin or extension. Premium users can create file-drop links or secure forms to receive files without requiring an account or password. The free plan covers one user, 25 MB attachments, and six months of inbox storage; the site also advertises 10 free messages with no credit card required. Premium costs $10 per user per month. Uncollected messages are destroyed after six months, and read files not marked for deletion are removed within 24 hours.

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.
