Introduction
IT/OT cybersecurity has become a core business consideration for critical infrastructure operators. It is now a customer issue, a business issue and, increasingly a regulatory issue. The conferences we took part in recently made this clear for companies operating renewable energy assets. The conversations focussed on whether systems are resilient, observable and ready for the realities of a more connected information technology (IT) and operational technology (OT) environment.
From keynote sessions to startup demos, concerns included: data privacy, secure remote access, patching discipline, AI governance, supply-chain trust, faster response to incidents, and overall operational resilience. Together, these sessions offered a useful snapshot of the trends that are key to energy operations and why they are important in practice.
| Conference themes | The details | Why this is important |
| IT/OT resilience | The events repeatedly moved conversations from compliance to operational resilience. | Customers want confidence that critical operations can continue during disruption. |
| Secure access | Remote support, privileged access and controlled connectivity were recurring topics. | Access must remain practical without increasing exposure. |
| AI governance | Agentic AI, model controls and data permissions were treated as governance issues. | Customers want AI to be useful, but also bounded, monitored and trustworthy. |
| Security operations | SOC modernization, SIEM, telemetry and faster response were central to many sessions. | Better visibility shortens the path from detection to action. |
| Privacy and classification | Data classification and document exposure examples made governance feel immediate and practical. | Customers need assurance that sensitive information is protected and correctly handled. |

Evidence and actions matter more than checkboxes compliance alone
A recurring question was whether security controls are actually working in practice, which cuts to the heart of what customers care about. Installed controls are not the same as effective controls. Whether the topic was patching, web application protection, remote access or incident detection, the strongest sessions focused on proof, visibility and operational follow-through rather than on checkbox compliance alone.
For customers in renewable energy, the messages translate into a practical set of priorities:
| Customer priority | What it means in practice |
| Data protection | Clear classification, controlled access and confidence that business-critical information is not overexposed. |
| Operational visibility | Knowing what assets exist (inventory), where vulnerabilities sit and how incidents are developing (logging and monitoring). |
| Secure support | Remote access that is encrypted, monitored and aligned with operational needs. |
| Incident readiness | Faster detection, clearer response processes and stronger continuity planning. |
| Supplier trust | Confidence that vendors, platforms and third parties, support security and compliance expectations. |
| Responsible AI | Using AI in a way that improves operations without creating new data or governance risks. |

The distinction between being compliant and being resilient
One of the strongest themes at the conferences was the distinction between being compliant and being cyber resilient. A firewall, VPN, WAF or patching process may exist on paper, but customers are increasingly asking whether those controls are configured correctly, monitored consistently and verified over time.
That distinction is especially important in OT environments, where continuity matters just as much as prevention. For energy operators, resilience means being able to keep operating, recover quickly and show evidence that protections are doing what they are supposed to do.
That is also why standardization and tiered security architectures remain relevant. While not all customers need the same solution/level of protection, they do need a clear path forward to understand better which solution is more suitable for them.
- Some sites need stronger perimeter isolation and better access control.
- Some may require WAN-DMZ-OT isolation, IDS visibility and SIEM support.
- Higher-criticality environments may require deeper IT/OT separation and more resilience by design.
These trends also explain why structured and scalable cybersecurity architectures are becoming increasingly important.
The GreenPowerMonitor, a DNV company (GPM) Security Tiers provide a standardized set of cybersecurity capabilities; while remaining flexible enough to accommodate specific customer requirements. Where certain services, features, or security controls fall within the customer’s scope of responsibility, the security tier can be adapted to align with operational and technical needs without compromising security outcomes.

Visibility, patching lifecycle, and the rise of smarter operations
In industry discussions, patching was a topic that came up repeatedly; the emphasis is moving from simply applying patches to a continuous cycle of discover, prioritize, patch and verify. Conference discussions highlighted the need to reduce the time between vulnerability identification and mitigation, while maintaining visibility of assets and risks across the environment. As threats become more autonomous and attackers move faster, organizations must focus on continuous visibility and risk reduction rather than one-time remediation efforts.
This also connects to the growing interest in SOC modernization. Sessions on telemetry, automated playbooks and next-generation SIEM made it clear that customers increasingly expect better visibility, not just more alerts. Discussions on centralized monitoring, telemetry and security analytics highlighted the growing need for better visibility across segmented IT and OT environments.
SecOps are focused on reducing time from detection to response
Several sessions showed how security operations are moving from reactive monitoring to incident-led response. Better telemetry, centralized analysis and playbook-driven response can shorten the path from detection to action, which is exactly what regulated and high-availability environments need. A well-established incident response plan is what allows operators to act with confidence during disruption.
Key trends and takeaways
The conferences were a useful guide to where expectations are heading. Secure remote support, stronger IT/OT separation, better visibility, responsible AI use, clearer data governance and faster incident handling are becoming part of critical infrastructure requirements. This is where GPM stays up to date on security trends, offering practical product, service and infrastructure solutions.
These trends are also closely connected to the practical questions many organizations are already considering: How is data classified? How is remote access controlled? How do we detect incidents earlier? What is the incident response plan? How is risk management handled? How do we use AI without creating new exposure? The clearer these topics become, the easier it is to map them to the systems and services that support operations.
Conclusion
The strongest takeaway from these conferences is that cybersecurity must remain closely aligned with operational realities. More important than which controls exist is how effectively those controls reduce disruption, protect data, support compliance and strengthen trust. This is particularly important in renewable energy, where digital systems are increasingly intertwined with critical operations.
For renewable energy operators, the priorities are becoming clearer:
- Protect sensitive and operational data through effective Information Assurance.
- Maintain secure remote access to critical systems.
- Improve visibility across interconnected IT and OT environments.
- Use AI within clearly defined security and governance boundaries.
- Respond to incidents in a way that reduces disruption and preserves trust.
These priorities increasingly define what operational resilience is in practice and reflect the direction in which customer expectations are evolving. This emphasizes the importance of moving beyond compliance-focused discussions toward practical outcomes that improve security, reliability and operational confidence.
For GPM, this reinforces the importance of combining strong cybersecurity practices with clear communication and practical solutions. Through standardized and tiered cybersecurity architectures that can be adapted to different operational environments and risk profiles, GPM helps customers translate cybersecurity requirements into measurable resilience outcomes. As customer expectations continue to evolve, the ability to turn cybersecurity objectives into operational value will be just as important as the technologies and controls that support them.
