Powering Progress While Defending Critical Infrastructure
From wind farms and field substations to public water systems and wastewater treatment plants, digitalization and connectivity are reshaping how the energy and utilities industry operates.
Connecting people, assets, and data drives efficiency and reliability but also creates new points of vulnerability. Legacy OT systems, isolated sites, and growing supply chain dependencies further widen the door to intrusion.
And in a sector where uptime and public safety are non-negotiable, even a minor breach or outage can have cascading consequences.

Top challenges for
E&U companies include:
24/7 critical operations
Even a short period of downtime can disrupt essential services and endanger public safety.
Third-party access risks
Vendors, service providers, and government agencies often require access to E&U networks, expanding your potential attack surface.
Limited visibility across hybrid environments
Third-party vendors, highly distributed sites, and undiscovered assets make it hard to gain a full picture of what’s really happening inside your networks.
Geographically dispersed sites
Distributed grids, remote substations, and field assets complicate centralized security management.
Legacy equipment, modern risks
Legacy SCADA systems, RTUs, and IEDs keep operations running but expose companies to sophisticated cyber threats.
Compliance demands
Increasingly complex and evolving mandates (NERC CIP, ISO 27001, TSA, NIS2, etc.) require continuous vigilance.
Safety threats
Cyber incidents in critical systems can endanger workers, the public, and essential infrastructure.
Nation-state & ransomware targeting
Adversaries increasingly view E&U networks as strategic national targets.
At Cyolo, we believe security tools that disrupt operations, cause downtime, or add complexity don’t belong in critical OT environments.
That’s why our remote access solution is built for speed, simplicity, and safety as well as security.
No solution gives me so much control and security like Cyolo. It’s everything I need in one solution.

With Cyolo PRO (Privileged Remote Operations), E&U companies get:
Fast, frictionless access
When every minute counts, Cyolo helps maximize uptime by providing connections with ultra-low latency and high availability. No more staring at spinning wheels as your VPN struggles to connect!
Easy deployment and simple scalability – without network changes
Deploy on-prem, on-cloud, or offline in under 90 days and with no need to change your network architecture. Then, seamlessly scale up or down according to your business needs.
Full visibility, full control
Monitor, record, and audit every privileged session to reduce insider threat and third-party access risks, with full activity logs, supervised access, and built-in reporting.
Zero-trust access that works for OT
Granular, identity-based access controls enforce the principle of least privilege, eliminate risky network-level access, and prevent lateral movement. Plus, all sensitive data stays within your trusted boundaries and is never stored or held by Cyolo.
Safer operations, stronger resilience
Keep production running, reduce downtime, and protect both your financial outcomes and the safety of your workforce.
Success Story: How Energy & Utilities
Companies Can Secure Access at Scale
Case Study
How Rapac Energy Solved OT Security Challenges with Cyolo
A leading power plant operator, Rapac Energy, needed to provide secure access to their OT and SCADA systems to external suppliers, global support teams, and customers. The company previously used a VPN, but access was slow and employees were frustrated. The new solution had to provide multiple security features that comply with stringent regulatory and internal requirements.
Rapac Energy looked to Cyolo to solve these challenges. The entire implementation process took only one day — the shortest implementation Rapac Energy had ever experienced.
