What is Email Encryption Software?
Email encryption software ensures the confidentiality and integrity of email communications by converting messages into unreadable formats that can only be decrypted by authorized recipients. It uses encryption protocols such as S/MIME and PGP to protect sensitive information from interception, eavesdropping, and unauthorized access. The software helps organizations comply with data privacy regulations like GDPR, HIPAA, and CCPA by securing emails containing personal or financial information. Email encryption can be applied at the message level, attachment level, or entire inbox, providing versatile protection for both internal and external communications. By safeguarding email content, businesses can reduce the risk of data breaches, maintain customer trust, and avoid costly compliance fines.
