Partnership ensures utilities have a secure way to transfer OT data into IT systems without exposing critical infrastructure to cyber risk
The electrical grid sits at an uncomfortable intersection right now. Utilities are being pushed to modernize, connect previously isolated systems, and pull real-time operational data out of substations and control centers to support smarter grid management. At the same time, the threat environment those systems are being opened up to has never been more hostile. Ransomware groups have demonstrated both the willingness and capability to target critical infrastructure, and the IT security playbook does not translate cleanly into environments where the consequences of a compromised system are measured in blackouts rather than data breaches.
Owl Cyber Defense and Foxguard have announced a partnership that addresses that tension directly, combining hardware-enforced one-way data transfer with OT-specific security and patch management to give utilities a way to modernize without dismantling the isolation that has historically been their primary defense.
What Each Company Brings
The partnership works because the two companies are solving adjacent but distinct problems that utilities need answered together.
Owl‘s core technology is the data diode, a hardware-enforced mechanism that allows information to flow in only one direction. Data can leave a substation or control center network and reach IT systems or cloud analytics platforms, but there is physically no return path for commands, malware, or any other inbound traffic. This is not a firewall rule that can be misconfigured or a software policy that can be bypassed through a vulnerability. The physics of the hardware enforces the isolation.
Foxguard brings OT-specific expertise in risk mitigation, patch management, and regulatory compliance, with particular depth around the frameworks that govern utility cybersecurity. NERC CIP, the North American Electric Reliability Corporation’s Critical Infrastructure Protection standards, and IEC 62443 are the two dominant compliance frameworks for grid operators, and navigating them while simultaneously modernizing aging infrastructure requires knowledge that generic IT security vendors rarely have.
The combination means utilities get reference architectures that are both technically sound and compliance-aligned, which matters considerably when regulators are asking hard questions about how critical assets are being protected.
The OT/IT Convergence Problem
For most of the electrical grid’s history, operational technology networks and IT networks were kept separate by design and often by physical distance. Control systems in substations ran on isolated networks that had no business talking to corporate systems, and that isolation was effective security even when the underlying technology was decades old and had no meaningful built-in security features.
Grid modernization has been eroding that separation steadily. Advanced grid controls, outage management systems, and real-time performance monitoring all require data to move between OT and IT environments. That data movement creates connectivity, and connectivity creates an attack surface.
Scott Orton, CEO of Owl Cyber Defense, described the bind utilities are in: “Utilities are being asked to modernize their most critical systems while keeping power reliable and resilient in the face of more storms, increasing load, and escalating cyber risks like ransomware. This partnership enables critical infrastructure operators to get vital updates and export performance data while never exposing isolated industrial networks to external threats.”
The reference architectures coming out of this partnership are designed to give utilities a tested, documented answer to exactly that problem rather than requiring each organization to design its own secure integration from scratch.
Why Reference Architectures Matter Here
Utilities are not software companies. They do not have large internal security engineering teams designing bespoke OT/IT integration architectures from first principles. What they need is documentation that shows precisely how to connect the systems they have in a way that has been validated, tested, and reviewed against the compliance requirements they are already accountable to.
That is what the partnership is producing. Tested reference architectures that demonstrate how Owl’s one-way transfer technology and Foxguard’s OT security and patch management layer work together give utilities something they can evaluate, adapt, and implement with reasonable confidence rather than starting from a blank page.
Susan Jenkins, General Manager at Foxguard, connected the data and security requirements directly: “Grid reliability and resilience depend on accurate, timely data from the field, and that data cannot come at the expense of security. By teaming with Owl, we will elevate our ability to help customers protect critical assets while also safely unlocking the information they need for advanced grid controls, outage management, and long-term grid-modernization efforts.”
The Regulatory Dimension
NERC CIP compliance is not optional for utilities operating across the North American grid. The standards set mandatory requirements for how critical cyber assets are identified, protected, and monitored, and non-compliance carries significant financial penalties. IEC 62443 adds an international framework for industrial automation and control system security that increasingly informs both procurement decisions and audit expectations.
For a utility evaluating how to modernize securely, having a partner combination that understands both the technical architecture and the compliance documentation requirements is practically significant. Security controls that work technically but cannot be demonstrated to auditors in the language of NERC CIP create their own kind of risk, and that is a gap that OT-specialist vendors like Foxguard are positioned to close in ways that general IT security vendors are not.
What the Broader Threat Picture Looks Like
Critical infrastructure attacks have moved from theoretical concern to documented reality over the past several years. Ransomware groups have hit pipeline operators, water utilities, and energy companies. Nation-state actors have demonstrated persistent access to grid infrastructure in multiple countries. The combination of aging OT equipment, expanding connectivity requirements, and sophisticated adversaries makes the electrical grid one of the more consequential cybersecurity problems currently in play.
Hardware-enforced isolation is not a complete security strategy on its own, but for the most critical control systems, it provides a guarantee that software-based controls cannot match. A data diode does not have a CVE. It does not have a patch cycle. The security property it provides does not degrade as the threat landscape evolves. For utilities trying to balance modernization against the consequences of getting security wrong, that kind of unconditional isolation for their most sensitive systems is worth building around.
