Cybersecurity for Critical Infrastructure

Securing critical infrastructure and cyber-physical systems is vital to national security, economic stability, and public trust. From energy grids and transportation to healthcare and manufacturing, these systems are increasingly connected — and increasingly targeted. Cyberattacks on physical infrastructure can have real-world, irreversible consequences. That’s why robust, tailored cybersecurity is essential to protect operations, ensure resilience, and safeguard lives. Yellow Cube helps partners secure these complex environments with trusted, industry-proven solutions.

Key cyber priorities

  • Airtight business (IT) and industrial (OT) network separation

  • Strict OT segmentation rules enforced by industrial firewalls

  • Secure and monitored access for 3rd parties

  • Detection and response capability (XDR) with zero trust

  • 24×7 security operations and incident management

Top solutions

  • Cynet AutoXDR

  • Group-IB attack surface management and supply chain security

  • OPSWAT MetaDefender secure IT-OT gateways

  • OPSWAT MetaDefender file scanning kiosks

  • Stormshield industrial firewalls for segmentation

  • Stellar Cyber OpenXDR

Protecting What Can’t Be Replaced

Critical infrastructure demands a distinct cybersecurity approach — one that accounts for its physical impact, limited redundancy, and operational constraints. Unlike traditional IT environments, these systems often can’t be patched due to uptime requirements, lack comprehensive backup solutions, and were never designed to defend against modern cyber threats.

Operational technology (OT) environments frequently rely on outdated protocols with no encryption, authentication, or data validation. Designed for isolated operation, these systems remain highly vulnerable to even basic attacks like man-in-the-middle interceptions.

But isolation is no longer reality. As industrial networks become interconnected with broader IT systems — through remote access, cloud services, and supply chains — they face a rapidly expanding threat landscape. The consequence of a breach isn’t just data loss — it’s real-world disruption, material damage, and public safety risk.

At Yellow Cube, we don’t just try to “secure” legacy OT systems — we build secure enclaves where they can operate safely. Wherever possible, we advocate for air-gapped separation as the gold standard. Where full isolation isn’t feasible, we provide secure, managed gateways that preserve airgap integrity while enabling controlled data flow. Advanced XDR solutions with passive sensors help monitor OT traffic without disruption, offering real-time visibility into assets and network activity.

Because attackers typically breach IT systems before pivoting into OT environments, strong IT and supply chain security is essential. That’s why we reinforce office IT networks with 24×7 managed detection and response, proactive attack surface management, and strict access controls — stopping threats before they can reach industrial layers.

And for environments where absolute security is non-negotiable — like nuclear facilities — we deliver formally validated, hardware-enforced optical data diodes to ensure 100% unhackable, one-way data flow.

In the world of critical infrastructure, trust is built through unbreakable defenses.
