Proofpoint Achieves #1 Market Share in Japan's Anti-Spam Email Market for Third Consecutive Year, According to Deloitte Tohmatsu Micke Economic Research Institute Survey

Japan Proofpoint K.K., a leading company in cybersecurity and compliance (Headquarters: Chiyoda-ku, Tokyo; President and CEO: Takeshi Nomura; hereinafter "Proofpoint"), has achieved first place in Japan's "anti-spam email" market by shipment value, according to the Deloitte Tohmatsu Micke Economic Research Institute's report titled "Current Status and Future Outlook of External Threat Protection Solutions Market 2025." Proofpoint captured 24.1% of the market share in 2024 and is projected to reach 29.1% in 2025, securing the top position for the third consecutive year.

The report indicates that Proofpoint's shipment value market share has consistently grown from 2022 through 2025 (projected). It attributes this growth to the increasing severity of impersonation email attacks, such as Business Email Compromise (BEC), and the rising corporate adoption of DMARC (Domain-based Message Authentication, Reporting, and Conformance) as an authentication technology. Additionally, Proofpoint's own research reveals that over 80% of new email attack campaigns are targeting Japan, underscoring the growing importance of advanced email threat protection for Japanese enterprises. In this market environment, Proofpoint's advanced email security solutions have earned high evaluation and trust from Japanese businesses, leading to this achievement.

Takeshi Nomura, President and CEO of Japan Proofpoint K.K., stated: "We are honored that our leadership has once again been validated by the Deloitte Tohmatsu Micke Economic Research Institute's survey. Achieving the No.1 market share not only highlights our strength in email security but further solidifies our leadership across the entire collaboration security landscape. This result is proof that our commitment to protecting customers from increasingly sophisticated and malicious cyber threats is widely recognized in the Japanese market. In response to the ever-evolving threat landscape, we will continue to expand our business beyond email security into AI security and data security, striving to deliver cutting-edge security solutions that enable our customers to conduct business with confidence."

Proofpoint provides AI-powered threat detection, detailed threat intelligence, and a comprehensive platform to protect organizations from attacks targeting the greatest threat to any organization—its people.
