List of the Top Secure Email Gateway Software in 2025 - Page 2

Protecting communications through email encryption is essential, as the majority of emails are sent in unencrypted plain text, making their content vulnerable to anyone who has access to the data stream. This vulnerability poses significant risks for businesses, organizations, and institutions, potentially leading to violations of legal standards. To improve security and build trust in electronic communications, CipherMail functions as a central mail transfer agent (MTA) utilizing a “store and forward” system. It temporarily retains incoming messages from both internal and external sources until they are either encrypted or decrypted, allowing for smooth delivery to the recipient without altering the email client or interfering with any SMTP server. CipherMail supports various email encryption techniques, including S/MIME and PGP, and can even embed encryption within PDF files, with activation based on certain triggers like keywords in the email subject line. In addition, CipherMail features a Data Leak Prevention (DLP) module that offers an extra layer of security against unauthorized data leaks. This thorough approach to email security not only safeguards sensitive information but also bolsters the overall reliability of electronic communications across numerous platforms, ensuring that users can confidently share information without fear of interception. The combination of these advanced features positions CipherMail as a leader in the realm of email security solutions.
