Their capabilities align closely with utility modernization and critical-infrastructure protection needs.
-
COMPETITIVE LANDSCAPE - STARTUPSTXOne Networks, Cyolo, SCADAfence, NanoLock Security, and XONA Systems are emerging strongly in the ICS security space of energy & power by delivering OT-native protection, secure remote-access solutions, device-level hardening, and advanced anomaly detection. Their technologies address growing requirements for securing distributed energy assets and modern digital substations.
Stronger ICS security investments across power networks are driven by the need to avoid unauthorized access, data tampering, and operational disruption. This has become more important as utilities deploy DER (Distributed Energy Resources) platforms, smart inverters, and digital protection systems. These additions increase device diversity and complexity, making secure onboarding, vendor compatibility, and ongoing device monitoring essential.
TRENDS & DISRUPTIONS IMPACTING CUSTOMERS' CUSTOMERS
Digital substations, renewable integration, and the expansion of distributed energy assets are changing how power systems must be secured. At the same time, cyber incidents affecting grids and generation sites are increasing. Tighter regulations and wider use of remote operations are pushing utilities to adopt better OT visibility, anomaly detection, network segmentation, and continuous monitoring to protect critical energy infrastructure.

Driver: Renewables integration increasing security needs
The fast growth of renewable energy and distributed generation is adding many new connected devices and control points across the grid. Cyber risks have increased as solar plants, wind farms, and smart inverters connect with older systems. To keep operations stable, utilities are investing in stronger OT security, continuous monitoring, and safer ways to coordinate grid operations.
Restraint: Slow modernization of legacy infrastructure
Many power systems still depend on old control equipment and long-life devices that were never designed with security in mind. Upgrading or securing these assets takes time, costs money, and can disrupt daily operations. Because of this slow progress, utilities struggle to clearly see what is happening across their networks and cannot improve cyber protection as quickly as needed.
Opportunity: Rising demand for OT asset visibility
Utilities need a clearer view of what is happening across substations, power plants, and field networks to spot unusual activity and reduce risk. Many operators now realize they have limited visibility into their OT environments. This is driving demand for tools that show connected devices in real time, track normal behavior, and bring monitoring into one place, helping teams respond faster when issues arise.
Challenge: Mixed OT protocols complicate monitoring and response
Power systems use many different communication methods, including standard and vendor-specific ones. This lack of consistency makes it hard to monitor everything in the same way or connect events across systems. As a result, security teams find it difficult to spot unusual behavior, respond quickly, and apply the same level of protection across complex networks built by multiple vendors.

Market Definition
According to Forcepoint, industrial control systems can consist of a complex network of interactive control systems or a small number of controllers. These systems receive information from remote sensors that measure and monitor process variables. From control valves to pressure gauges, an ICS sends commands and receives alerts from many different components. ICS security is a security framework that protects these systems against accidental or intentional breaches and risks.
ICS security solutions consist of a comprehensive array of technologies such as Distributed Denial of Service (DDoS), Intrusion Detection and Prevention System (IDPS), anti-malware/antivirus, firewall, virtualization security, Security Information and Event Management (SIEM), SCADA encryption, Unified Threat Management (UTM), Data Loss Prevention (DLP), and Identity and Access Management (IAM).
