EMERYVILLE, Calif., – April 23, 2026: Tanium, a leader in Autonomous IT, announced today that Mizuho Financial Group, one of the world’s largest full-service financial conglomerates, has expanded its deployment of the Tanium Autonomous IT Platform to enhance its security operations and threat hunting driven by real-time endpoint intelligence.
“Tanium provides a single, unified platform which allows us to effectively optimize our security operations,” said Yohhei Yonei, deputy general manager, Overseas Coordination Team, Cyber Security Management Department at Mizuho Financial Group. “By making Tanium a standard part of our operations, we aim to optimize both costs and resources.”
As one of Japan’s megabanks with more than 60,000 employees across over 100 locations in the Americas, Asia and Europe, Mizuho Financial Group is entrusted with managing nearly $2 trillion in assets for over 22 million customers. When banking services becoming increasingly digital and financial institutions faced with a threat landscape growing in both volume and sophistication, Mizuho Financial Group turned to Tanium to provide the visibility into endpoint behavior needed to investigate threats and mitigate risk - in real time.
“We’ve found that rule-based monitoring often results in a high number of false positives, which places a heavy burden on monitoring operations, but executing queries based on the Tanium platform allows us to detect legitimate behaviors from scanning products and vulnerability assessment tools,” said Masahiro Doi, vice president, Cyber Response Team, Cybersecurity Management Department at Mizuho Financial Group. “The Tanium Autonomous IT Platform has proven it can be used for broader threat hunting and detection as well, and we have plans to expand its use internally.”
Mizuho Financial Group identified Tanium as the optimal choice to confront the cyber risks presented by ransomware, third-party risk and nation-state actors. With the Tanium Autonomous IT Platform, the megabank is able to observe endpoint behavior in real time and continuously monitor for malicious activity, effectively eliminating manual workflows and reducing the number of false positives.
“We are deeply honored to play a central role in supporting Japan’s financial infrastructure through our work with Mizuho Financial Group,” said Hidenori Harada, senior vice president, Tanium Japan. "In an increasingly sophisticated and complex threat landscape, Tanium’s unified platform with real-time intelligence is key to powering the forward-looking threat hunting initiatives Mizuho Financial Group is looking to drive. We will continue to strive to deliver greater value by supporting our customers in protecting their critical systems and information.”
