What LinkGuard does
LinkGuard is an OT/ICS cybersecurity platform developed and operated by Blue Ridge Networks, Inc., a privately-held cybersecurity company headquartered in Chantilly, Virginia. The platform provides preemptive protection for critical assets, data, and operations in operational technology environments through secure remote access, network segmentation, and zero-trust architecture. Its proprietary CyberCloak technology delivers data anonymization and stealth capabilities for critical assets, and the forthcoming LinkGuard Quantum offering extends protection to post-quantum cryptography threats. The portfolio is delivered via hardware appliances branded RemoteLink combined with software subscriptions and complementary products including AppGuard (application security) and Borderguard (border security).
LinkGuard serves industrial manufacturers, regulated sectors including utilities, healthcare, and government agencies, and commercial customers in financial services, retail, and food and beverage industries. Customer evidence includes multi-site deployments across Fortune 500 industrial firms, global utilities, and energy management organizations, with documented installations spanning Canada and the United States. Distribution is driven by a direct enterprise field sales motion targeting CSOs and security leaders, supplemented by a structured channel partner program with portal-based enablement. Strategic technology partnerships with Dragos (OT/ICS layered defense), Garland Technology (network visibility), and AWS (cloud marketplace) extend market reach into federal, industrial, and cloud-native buyers.
The business model centers on annual licensing and subscription revenue from the LinkGuard platform and RemoteLink appliances, with recurring software subscription for security updates and management. Professional services revenue is generated through cybersecurity assessments supporting compliance journeys for regulated buyers. Pricing is not publicly disclosed and requires direct sales engagement. The company has operated without disclosed institutional funding since 2001 and holds multiple registered trademarks (LinkGuard, CyberCloak, AppGuard, Borderguard, Blue Ridge Networks), with Gartner recognition as a top provider for Cyber-Physical Systems Remote Access Solutions and U.S. Department of Energy National Renewable Energy Laboratory validation of CyberCloak capabilities.

LinkGuard competitors and assessment
Company assessmentBroad incumbents
- Fortinet: Fortinet offers network security appliances, SASE, and OT/ICS security through FortiGate and the OT Security service, competing with LinkGuard for industrial network-segmentation and secure-remote-access deals with overlapping hybrid IT/OT buyer profiles.
- Palo Alto Networks: Palo Alto Networks is a broad cybersecurity incumbent with OT/ICS offerings via its Prisma SASE and Cortex lines, providing zero-trust, segmentation, and remote-access capabilities that overlap with LinkGuard's positioning at the IT-OT boundary.
- CrowdStrike: CrowdStrike's Falcon platform extends endpoint and identity protection into OT/IT environments, providing an alternative zero-trust and remote-access narrative to industrial buyers that competes with LinkGuard on enterprise security platform deals.
Emerging players
- Darktrace: Darktrace applies AI-driven anomaly detection across IT and OT networks, including industrial and critical-infrastructure environments, providing an AI-first alternative to LinkGuard's segmentation-and-CyberCloak approach for the same industrial buyers.
- Opswat: Opswat provides critical-infrastructure cybersecurity for OT/ICS environments including data diode and secure remote-access products, addressing network segmentation and industrial perimeter defense similar to the LinkGuard platform.
