Anthropic has launched a Critical Infrastructure Defense Program to help strengthen cybersecurity for essential services, with Hitachi joining as a founding partner. The initiative, launched on October 8, 2026, targets infrastructure such as power, water, manufacturing and transportation systems, where security failures can disrupt physical operations as well as digital networks.
The program aims to bring Anthropic’s Claude models into products and services offered by system integrators and cybersecurity providers that work with critical infrastructure operators. Its stated focus is faster identification and remediation of vulnerabilities. Hitachi will participate in working groups and contribute its experience with operational technology, or OT, including the control systems used to run industrial equipment and infrastructure.
The effort addresses a security challenge that differs from protecting conventional office IT. Infrastructure operators often need to keep equipment running continuously, limiting opportunities to shut systems down for software updates or other security changes. A patch that is straightforward to deploy on a business computer can require more extensive planning and validation when it affects equipment controlling a physical process.
Operational technology encompasses systems that monitor or control machinery and industrial processes. In these environments, cybersecurity decisions must account for safety, reliability and service continuity alongside the protection of information. Identifying a software flaw is therefore only part of the defensive process: operators also need to assess how a proposed fix could affect equipment and determine when it can be applied safely.
AI-assisted security tools can support tasks such as examining software for weaknesses and helping teams investigate potential fixes. Their outputs still require validation, particularly when changes could affect essential services. The program’s planned integration through infrastructure-focused providers places Claude within products and services used to support those operators, rather than describing a single standalone security tool.
For Hitachi, the new program extends an existing relationship with Anthropic. The companies entered a strategic partnership in May 2026. Hitachi subsequently joined Project Glasswing in June, an initiative focused on protecting important software and advancing cybersecurity practices. In July, it announced work through that initiative to accelerate security validation for critical infrastructure using Claude Mythos Preview.
Hitachi also launched HMAX Cyber in September, describing it as an operational resilience service intended to support business continuity. The company plans to use insights from the new defense program and discussions with other participants to improve that service and strengthen the security capabilities of its OT products, including industrial control systems.
The announcement establishes the program’s launch date, its intended sectors and Hitachi’s founding role, but does not provide a timetable for specific integrations or measured results from deployments. Hitachi’s outlined contribution is participation in the working groups and the application of its infrastructure expertise to the program, with improvements to HMAX Cyber and its OT offerings planned as the collaboration develops.
