Proofpoint Secures No. 1 Market Share in Domestic Insider Threat Countermeasures, According to Deloitte Tohmatsu MIC Research Institute Survey

Proofpoint, a leading company in the field of cybersecurity and compliance, announced that its Japanese subsidiary, Proofpoint K.K. (Headquarters: Chiyoda-ku, Tokyo; Representative Director and President: Ken Nomura), has achieved the number one market share in shipment value for 'System Audit Logging Tools' within the manufacturing, distribution, and communications sectors in Japan for fiscal year 2024, according to a research report by Deloitte Tohmatsu MIC Research Institute titled 'Status and Future Prospects of the Insider Threat Solutions Market 2025.' The market shares are 52% in manufacturing, 63% in distribution, and 60% in communications.

According to the report, the company maintains an overwhelming lead in 2025 (projected), with shares of 58% in manufacturing, 70% in distribution, and 64% in communications, solidifying its position as a leader in insider fraud and insider threat countermeasures.

In recent years, the theft of critical information by departing employees due to increasing labor mobility and misconduct by internal staff have become serious risks for companies in Japan. According to Proofpoint's annual 'Data Security Landscape Report 2025,' the majority of data leakage incidents continue to be human-related. About 48% of Japanese organizations (compared to a global average of 58%) attribute these incidents to negligent employees or contractors, 39% (global average 42%) to compromised user accounts, and 20% (global average 32%) to malicious insiders. Consequently, the adoption of 'System Audit Logging Tools' that prevent misconduct through automatic PC activity recording and real-time alerts is advancing as an essential business continuity measure. Proofpoint Insider Threat Management (ITM) and other data security solutions visualize insider threats originating from negligence, malice, or account compromise, centralizing the detection, investigation, and prevention of risky behaviors. Using lightweight agents, it collects telemetry from endpoints, email, and the cloud, blocking unauthorized data exfiltration to USB drives, cloud synchronization, the web, and generative AI sites in real-time, while assisting in rapid investigations and collaboration with HR and legal departments through evidence including screenshots. This result demonstrates that Proofpoint's solutions are highly valued for the insider threat risks faced by Japanese companies.

Ken Nomura, Representative Director and President of Proofpoint K.K., stated: 'We are honored that the Deloitte Tohmatsu MIC Research Institute survey has demonstrated our leadership in both the external and internal threat countermeasures markets. This result is a testament to the strong trust of our customers who want to protect their most important asset—data—from internal risks amid growing labor mobility. Proofpoint remains committed to supporting our customers' security and compliance from every angle with market-leading solutions, ensuring they can focus on business growth with peace of mind.'
