Market Growth Factors

The U.S. email encryption market is propelled by the alarming rise in cyberattacks and data breaches. Notably, from November 2023 to April 2024, there were 2,741 incidents resulting in 6,845,908,997 breached records. Misconfigured Google Firebase websites alone accounted for 916 incidents. This escalating threat landscape pushes sectors such as healthcare, finance, and government to prioritize email encryption for safeguarding sensitive information.

Stringent compliance regulations including HIPAA for healthcare, GLBA for financial institutions, and GDPR for data privacy compel organizations to adopt robust email encryption solutions. Companies invest heavily to ensure emails are protected both in transit and at rest to avoid legal penalties and enhance customer trust. For example, in August 2024, NIST released post-quantum encryption standards designed to shield sensitive data including emails from emerging quantum computer threats, highlighting the evolving regulatory landscape.

The increasing adoption of cloud-based platforms such as Microsoft 365 and Google Workspace is another major market driver. These platforms hold critical data making them prime targets for cyberattacks. Email encryption delivered through cloud services offers scalability, flexibility, and real-time protection. Cloud adoption coupled with remote work trends encourages businesses, especially SMEs, to prefer cost-effective cloud-based encryption solutions. Strategic acquisitions, like KnowBe4’s purchase of Egress in April 2024, further enhance cloud email security offerings, cementing this growth trajectory.
