    Ciphermail Appliance Reviews
    Email encryption is crucial for safeguarding communications, as most emails are transmitted in unencrypted plain text, which exposes their content to anyone who can access the data stream. This lack of security is often unacceptable for businesses, organizations, and institutions, and could potentially breach relevant legal requirements. To enhance security and foster trust in communications, CipherMail serves as a central mail transfer agent (MTA) operating on a “store and forward” model. It temporarily stores incoming emails from both internal and external sources until they are encrypted or decrypted, enabling seamless forwarding to the recipient without requiring any modifications to the email client and working in conjunction with any SMTP server. Email encryption methods supported by CipherMail include S/MIME, PGP, or even embedding within a PDF file, and can be initiated based on specific triggers, such as keywords in the subject line. Additionally, CipherMail is equipped with a Data Leak Prevention (DLP) module to provide further protection against unauthorized data exposure. This comprehensive approach to email security not only protects sensitive information but also reinforces the integrity of electronic communications across various platforms.
