Rising instances of enterprise email threats are expected to drive the growth of the email encryption market. Email threats involve cybercriminals impersonating reputable organizations to access sensitive data. Email encryption protects communications by applying advanced technologies to secure emails end-to-end, preventing unauthorized access and mitigating risks associated with email threats. For example, according to Acronis, a Switzerland-based cybersecurity company, email attack occurrences surged by 293% in the first half of 2024 compared to the same period in 2023. Therefore, increasing enterprise email threats are fueling demand for email encryption solutions.

A prominent trend gaining traction in the email encryption market is the shift from traditional email encryption tools to advanced email encryption solutions. Advanced email security involves encoding email content while it is in transit to ensure data security. Major companies are adopting advanced technologies, such as client-side encryption, to enhance the security of organizations' emails. For example, in October 2023, Google LLC, a US-based technology company, introduced client-side encryption in the mobile version of Gmail for business security. This feature encrypts data on the sender's device before transmission to the recipient's device, ensuring that only the sender and recipient possess the keys to decrypt the data, thereby enhancing security and restricting access to unauthorized entities, including Google.

In December 2023, Proofpoint Inc., a US-based provider of cybersecurity and compliance solutions, acquired Tessian, a UK-based provider of email encryption solutions, for an undisclosed amount. This acquisition strengthened Proofpoint’s email security capabilities by integrating Tessian’s AI-powered technology, which detects and prevents email threats and data loss from risky user behaviors.
