SOLUTIONS BRIEF

Zero Trust OT Cybersecurity Protection for Battery Energy Storage Systems

In May 2025, the revised NERC CIP framework requires that lower capacity BESS systems rated at 20 MVa or greater with a connection at 60 kV or higher be subject to NERC CIP. These newly regulated assets must demonstrate compliance by May 2026 or face fines of up to $1M per day for non-compliance. BlastWave’s approach to delivering NERC CIP security solutions for the BESS market focuses on operational simplicity for critical infrastructure at scale.

BlastWave protects Battery Energy Storage Systems (BESS) with a unique overlay Zero Trust Protection architecture. It supports key foundational security requirements with less operational complexity and lower TCO than traditional OT security offerings. BlastWave’s solution addresses key NERC CIP requirements faster and more economically than conventional “bolt-on” OT security solutions.

Secure Remote Access

Passwordless remote access is phishing-resistant and removes credential theft as a risk factor.

Network Segmentation

Software-defined segmentation allows BESS networks to be segmented by risk factors and ensures least privilege access to each segment.

Network Cloaking

Create a secure overlay to protect legacy systems from vulnerabilities, shield them between patch windows, and limit downtime by creating segmentation for BESS systems.

BlastShield solutions require only 10% of the installation time, need 50% less maintenance, and cost 25% of traditional OT security solutions. BlastWave’s solutions are optimized for OT and built with Secure-By-Design principles from Day 1. These comprehensive protection solutions deliver:

Enhanced Operational Uptime

Reduces downtime associated with patching vulnerable operational systems with network cloaking

Enhanced Resilience

BESS networks and systems are undiscoverable to hackers, preventing targeted cyberattacks and cloaking Zero Day vulnerabilities.

Enabling secure BESS operations

With geographically dispersed assets and greater reliance on remote maintenance, BlastWave prevents unauthorized access or manipulation of BESS systems.

Lowered Operational Costs

Existing staff can install and maintain systems without adding costly OT cybersecurity hires.

Increase Uptime

by eliminating cyber security risks before they can gain a foothold in your network.

Improve Safety

by ensuring that all connectivity to the BESS systems is secure and encrypted, preventing the modification of sensor data in flight.

Lower Costs

by not requiring expensive IT personnel or platforms and simplifying the installation, operation, and management of OT cybersecurity solutions

BlastShield™: Zero Trust OT Protection for Battery Energy Storage Systems

BlastWave in Battery Energy Storage Networks

Supports key NERC CIP security requirements with minimal impact or downtime to existing operations.

Extending patch cycles while mitigating security controls increases uptime. Securing and encrypting all BESS system connectivity improves resilience, preventing sensor data modification in transit.

Lower Total cost of ownership with decreased capital expense, lower maintenance labor due to decreased complexity of maintaining multiple OT security integrations, and reduced requirements for specialized OT security expertise to own and operate.
