MailHippo vs Mimecast Secure Messaging

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.

Mimecast Secure Messaging helps organizations protect sensitive information sent by email, including financial records and customer data. It sends protected messages through a secure web portal; Mimecast says the information stays in its cloud. Senders can set read receipts and expiry dates, and restrict printing or replies. Messages and attachments are scanned for viruses, checked against data leak prevention policies, and stored in an AES-encrypted archive. Recipients log in to retrieve messages, download attachments, and reply securely. Gateway policies can initiate the service, and administrator-defined criteria can trigger Office 365 encryption when TLS is unavailable. Senders and recipients need no additional software or hardware. The service supports Android, iOS, macOS, web, and Windows, and includes Outlook integration and administrative access controls. Pricing is on request. The Critical, Advanced, and Premium plans all include secure message and large-file delivery and email continuity; their listed security coverage varies by plan.
