Network Integrity Systems

What Network Integrity Systems does

Network Integrity Systems (NIS), founded in 2003 in Conover, North Carolina and now headquartered in Hickory, NC, is a privately held developer of optical fiber sensing technology that converts standard fiber optic cables into continuous distributed sensors for detecting physical intrusions, tampering, and environmental changes on network infrastructure. The company's portfolio is organized into three hardware product families — INTERCEPTOR (CNSSI 7003-compliant Alarmed Protected Distribution Systems for U.S. government and military classified networks), VANGUARD (network infrastructure security for enterprises, data centers, and critical infrastructure), and SENTINEL (perimeter and asset intrusion detection) — unified by the INSIGHT alarm response and management software platform. Technical differentiators include 36 U.S. and foreign patents covering DAS-based acoustic sensing, smart-filtering to eliminate false alarms, auto-configuration, and a point-to-multipoint architecture; measurable performance metrics include 55dB dynamic range on single-mode fiber, 1-meter location resolution, and over 35 million port-hours of in-service operation. Certifications span CNSSI 7003, DISA RMF, NIST SP 800-53, UL, FCC, IEC, and CE, supporting the company's anchor position in federal and defense markets.

NIS operates an enterprise field sales model with sales engineering and project services supporting needs assessment, design, and installation, supplemented by a certified partner network (Atlantic-CommTech, Net-Reps, Envistacom) and distribution through WESCO/CSC's Secure(it) program. Revenue is generated through hardware sales (one-time), INSIGHT software subscriptions, extended warranty and support plans (recurring), and professional services, with quote-based multi-year contracts and no publicly disclosed pricing. The customer base is concentrated in U.S. federal government and defense — including the Department of Defense, all military branches, the Department of Justice, the Department of Homeland Security, intelligence agencies, and defense contractors — with secondary reach into power utilities, data centers, and foreign governments. The company has 11-50 employees and has been self-funded, with no external venture or private equity rounds disclosed.

Core offering

Network Integrity Systems designs, manufactures, and sells optical fiber sensing hardware (INTERCEPTOR, VANGUARD, SENTINEL product families) and the INSIGHT alarm response/management software platform. Its technology transforms standard optical fiber cables into continuous sensors that detect physical intrusions, cable tampering, and environmental changes on classified networks, enterprise infrastructure, and critical facility perimeters.

Product overview

Network Integrity Systems offers an integrated portfolio of optical fiber sensing products organized into three main product families: INTERCEPTOR (for US Government and Military with CNSSI 7003 compliance), VANGUARD (for private enterprise, data centers, and critical infrastructure), and SENTINEL (for perimeter and asset protection). The portfolio centers on fiber optic sensing technology that turns standard optical fiber into continuous sensors for detecting intrusions, temperature changes, and physical disturbances. All products integrate with INSIGHT, a unified alarm management and response platform that provides centralized monitoring, intelligent event processing, and seamless integration with existing security systems. Add-on modules include INTERCEPTOR AFFIRM (automated sensor verification), INTERCEPTOR ECLIPSE (automated data shutoff), and INTERLINK (integration bridge for existing infrastructure). The company also offers sales engineering, project services, and extended warranty/support plans.
