SecureLineEmailEncryption has been providing an email security solution for mobile devices, desktop applications, and LuxSci's WebMail since 2005. It is HIPAA compliant, making it suitable for medical professionals sending ePHI in emails. SecureLineEmailEncryption ensures the secure transfer of sensitive patient health information over the Internet. It integrates secure email transmission modes to ensure secure communication regardless of the recipient's email system. SecureLineEmailEncryption supports TLS, MTA-STS, and uses FIPS/NIST-recommended security protocols and ciphers. It provides secure email delivery, authentication, storage, transmission, and auditing for messages. SecureLineEmailEncryption uses public key certificates (PGP and/or S/MIME) to encrypt email messages before sending. It allows you to adjust between high usability and high security, offering unique features like Dynamic TLS, which determines at the time of message delivery which recipients support TLS. SecureLineEmailEncryption automatically falls back to Escrow or PKI for secure message delivery. It ensures HIPAA-compliant email messages sent via SMTP, API, or WebMail are secure while allowing exceptions for usability. All data is encrypted at rest with SecureLineEmailEncryption, mitigating threats to email security and privacy.
