A new reality for energy leaders

Energy is one of the most targeted sectors for cyberattacks, and leadership is increasingly accountable for technology risks that were once treated as IT issues.

Quote in large text discusses compliance as a paperwork exercise until incidents expose real risks; to the right is a headshot of Steve Mathis, Chief Customer Officer, Open Systems, highlighting key insights from the February release notes.

How the operating reality of energy networks has changed

The energy sector has evolved faster than the security assumptions it was built on. What were once clearly separated environments — business systems and operational technology — now rely on shared infrastructure, shared access, and shared vulnerabilities.

Comparison chart from the February release notes shows five cybersecurity areas “Five Years Ago” vs “Today,” highlighting changes in infrastructure, access, incidents, perimeter, and compliance with contrasting bullet points for each era.

This shift not only changes how energy operations run, but also what is at stake when something goes wrong.

What this means for energy leaders

In connected environments, IT decisions directly shape outcomes that senior leaders are accountable for, with immediate, tangible consequences across the entire organization.

Section titled "Operational Continuity" with a broken circuit icon. Text explains that IT network compromise, as highlighted in the February release notes, can lead to shutdowns, safety incidents, and costly downtime affecting the whole organization.

Graphic with the title "Regulatory Exposure." Icon of stacked papers labeled NIS2, CER, and IEC 62443. February release notes highlight how these regulations raise compliance standards for energy operators in Europe and boost board-level accountability.

Infographic section titled "Financial Fallout" with a money bag icon. Text explains that energy sector breaches can cost millions in fines, insurance, recovery, and lost trust—February release notes compare these costs to much lower prevention expenses.

A warning icon and a truck icon next to text highlighting supply chain vulnerability, referencing the February release notes to explain that attacks on critical infrastructure often come through trusted third-party contractors or vendors.

A safety icon and heading read "Safety & Human Risk." Text explains that compromised pressure, temperature, and power systems cause physical, not digital, consequences. February release notes highlight that lives are at risk, not just fines.

Understanding these risk areas is the first step toward managing them and deciding where leadership attention and ownership are required.

The regulatory pressure is real, and it’s personal

Senior leaders within critical infrastructure — technical or not — are increasingly expected, not only to approve and oversee cyber risk measures, but also to understand the risks and their operational impact.

Fragmented vendor setups, often the result of siloed decisions, make meaningful oversight difficult. To meet regulatory expectations, energy leaders must be deliberate in provider choices, ensuring IT decisions reflect operational realities.

Infographic listing five key requirements for an OT security provider—IT & OT coverage, operational ownership, proven compliance, continuous visibility, and single accountability—each with a brief description and icon from the February release notes.

Your provider can either make or break your ability to comply with critical-sector regulations. Choose wisely, and regulatory compliance can become a strategic advantage rather than an ongoing burden.

Turning complexity into something manageable

Managing security and compliance in complex IT and operational environments is rarely about tools. At Open Systems, we provide sustained operational support built on three fundamentals:

  • Experience securing legacy and operational systems where long‑lived technologies now interact with modern IT.
  • Hands‑on support for regulatory requirements, including NIS2 compliance and IEC 62443‑aligned operations.
  • An operating model built for continuous control, clear accountability, and regulatory evidence over time.

In practical terms, we support organizations at every stage of the OT security journey.

A three-step OT cyber risk management process—Asset Inventory, Segmentation, and Risk Management—is now enhanced with updates from the February release notes. Each step includes brief descriptions and icons for improved clarity.

How does this play out in your operating reality? Exchange perspectives on technology risk, regulatory pressure, and operational realities with Steve Mathis, Chief Customer Officer and OT security expert.
