Free Online Seminar on IT/OT Security with Zero Trust

In recent years, ransomware attacks on major corporations have become increasingly prevalent, significantly impacting our daily lives. With cyber threats now more tangible than ever, organizations, regardless of their industry or size, must prioritize cyber security enhancement.

A pivotal shift is occurring; companies are transitioning from boundary-based defenses — which focus primarily on preventing breaches — to more proactive measures that assume breaches may occur. Introducing these proactive defenses can help mitigate the spread of ransomware and minimize damage, allowing businesses to continue operations without losing critical data.

On December 4, 2025, from 3 PM to 4 PM, we invite you to our free online seminar titled "Zero Trust Segmentation: Case Studies on IT/OT Security." This event follows our successful seminar held on October 22, 2025, at "Security Days Fall 2025 Tokyo," where we unveiled next-generation ransomware protection strategies. The feedback was overwhelmingly positive, with attendees expressing a desire for further presentations due to the in-depth focus on OT security.

The seminar will feature insightful discussions led by Masahiko Ishibashi, our Security Analyst, and Venky Raju, Field CTO of ColorTokens. They will elegantly weave together current IT/OT security trends and the cutting-edge technology known as "Zero Trust Segmentation," including practical demonstrations.
