The email encryption market has experienced significant growth, driven by the increasing need to protect sensitive communications in a digitally connected world. Initially, its adoption was mainly confined to regulated sectors such as banking and healthcare to comply with industry-specific mandates. Early email encryption technologies were relatively basic, often relying on manual key exchanges and user-driven encryption methods. However, as email became a key target for cyber threats such as phishing, business email compromise (BEC), and data breaches, organizations across various industries began implementing more sophisticated encryption solutions to safeguard their communications and comply with strict data privacy regulations like GDPR, HIPAA, and CCPA.

Email encryption is a security process that ensures messages cannot be accessed by unintended or unauthorized recipients. It transforms the original message by encoding it into an unreadable or indecipherable format.
