In today’s hyperconnected world, data centres are no longer just infrastructure—they are mission-critical assets that power digital transformation, business continuity, and national resilience. But as their role expands, so does their risk surface. From ransomware campaigns targeting backup systems to insider threats and increasingly sophisticated attacks on operational technology, data centres face a unique convergence of cyber and physical risks.
This is where Hitachi Cyber steps in.
As the global cybersecurity arm of Hitachi, our mission is simple but powerful: to help organizations operate securely at scale, with protection that’s as resilient as the infrastructure they rely on. Nowhere is this more vital than in data centres.
The Stakes Are Rising
Downtime is not just a technical issue—it’s a reputational and financial one. A single breach or service interruption can cascade across business units, disrupt customer services, and trigger regulatory scrutiny. According to industry estimates, the average cost of unplanned downtime for large organizations exceeds $9,000 per minute, with high-risk sectors like healthcare and finance facing hourly losses upwards of $5 million.
Yet, while many organizations have invested in physical redundancies and backup systems, fewer have addressed the full spectrum of cybersecurity risk—from lateral movement across networks to AI-driven threat vectors.
A Multi-Layered Approach to Data Centre Protection
At Hitachi Cyber, we support data centres through a comprehensive, layered strategy that includes:
24/7 Managed Security Operations
Our global network of Security Operations Centers (SOCs) operates around the clock to detect and respond to threats in real time. With analysts stationed across multiple continents, we provide true timezone-spanning monitoring and rapid incident triage—minimizing dwell time and helping clients maintain uptime and trust.
Intelligence-Led Defense
Threats evolve quickly—and so must your defenses. Our Cyber Threat Intelligence (CTI) team continuously monitors global threat activity, including those targeting hypervisors, DNS infrastructure, and OT systems embedded in data centre environments. We translate intelligence into action through proactive threat hunting, customized detection rules, and prioritized alerts that cut through the noise.
Incident Response & Forensics
When an incident does occur, speed and clarity are critical. Our digital forensics and incident response team supports rapid containment, root cause analysis, and recovery planning—ensuring that every step is legally defensible and operationally sound. Whether facing ransomware, insider abuse, or a supply chain breach, our experts help clients regain control quickly and confidently.
Penetration Testing & Security Validation
We don’t wait for attackers to expose weaknesses—we simulate them. Our team conducts red-teaming, internal and external penetration testing, and OT-specific assessments to uncover vulnerabilities before adversaries can. The result: more resilient segmentation, better access controls, and stronger safeguards across IT and OT layers.
Compliance and Cyber Governance
For many data centres, compliance isn’t optional—it’s foundational. Whether aligning with DORA, NIS2, ISO 27001, HIPAA, or GDPR, our advisory services help organizations build governance programs that are both audit-ready and operationally meaningful. We also provide virtual CISO services, privacy impact assessments, and support for incident response playbooks.
Secure AI Advisory
As data centres increasingly incorporate automation and AI, new risks emerge. We now offer Secure AI advisory services to help clients govern their AI use responsibly—covering areas such as model risk management, AI prompt injection mitigation, and secure deployment strategies aligned with evolving GRC frameworks.
Looking Ahead: Resilience by Design
In a world where cyber threats are relentless and regulation is tightening, data centres must evolve from being merely robust to being resilient by design. That means embedding cybersecurity not as an add-on, but as a core pillar of operational excellence.
At Hitachi Cyber, we believe that real leadership in cybersecurity isn’t just about stopping attacks—it’s about enabling trust, performance, and growth.
If your organization operates or relies on data centres, the question isn’t whether cybersecurity matters. It’s whether it’s built to scale.
Let’s build that foundation—together. Contact us for more information.
