GridShield - 2026 Pricing, Features, Reviews & Alternatives

GridShield is an on-premises, air-gapped OT cybersecurity and NERC CIP compliance platform built for power generation and transmission operators. Deployed entirely inside the customer network with no cloud dependency, it continuously collects read-only evidence from OT and IT devices across 42 supported device types using 16 read-only or passive protocols. Every collected record is stored in a SHA-256 hash-chained Evidence Vault, producing tamper-evident, auditor-verifiable documentation. RSAW worksheets for all 14 FERC-approved CIP standards are auto-populated from collected evidence, replacing manual screenshot capture, spreadsheet-based access reviews, and pre-audit evidence scrambles. A default 5-minute collection interval applies to polled sources, while push sources are collected in real time. Modbus write function codes and DNP3 select/operate commands are blocked at the Node, ensuring no control commands are issued to protection systems.

GridShield targets electric power generation and transmission sites including solar, battery storage, wind, substations, and generation plants operating under NERC CIP obligations. The platform also addresses NIS2, UK CAF, SOCI, KSA OTCC, and IEC 62443 frameworks. A BES Cyber System asset inventory tracks devices with impact ratings and CIP roles, and device coverage is displayed per vendor across all 42 supported types. The companion tool DocPilot drafts and gap-checks CIP-003 and CIP-013 compliance documents using a local AI model, with a mandatory human review step required before any output is used.
