MailHippo vs Proofpoint Email DLP and Encryption

MailHippo is a secure email messaging platform designed to protect patient data with HIPAA-compliant email. It works with a user's existing email address and provider, and MailHippo says users can begin sending and receiving encrypted messages without setup or configuration. SendSafe provides a personalized URL through which anyone can send an encrypted message to a MailHippo inbox, including people without a subscription. Messages use SSL/TLS 1.2 or higher in transit, while message bodies and attachments are protected with AES-256 encryption at rest; the key ring is also encrypted. Every plan includes a HIPAA Business Associate Agreement, and message-access records include the authorized user, date, time, and records accessed. The API supports attachments, CC/BCC, HTML content, and inbound messages through a webhook. Basic costs $4.95 a month per user and Pro costs $7.95 a month per user; both are month-to-month. A 30-day trial is available, and there is no free plan. MailHippo was founded in 2019 and is headquartered in Pompano Beach, Florida.

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.
