What the Metcalf Attack and Modern Cyber Campaigns Against our Nations Critical Infrastructure Reveal About the Need for Integrated Physical and Cyber Defense

From uptime assurance to intrusion detection and environmental monitoring, Network Integrity Systems delivers a continuous, unbroken line of defense—safeguarding every link in your data center ecosystem

In today’s environment, where metal detectors and clear bag requirements are the norm, even well-secured venues are vulnerable. Open-air settings lack the controlled access of indoor spaces, and elevated vantage points—like rooftops—can easily go unmonitored. These gaps leave exposed...

When it comes to securing classified networks, performance isn’t optional—it’s mission-critical. That’s why INTERCEPTOR^NX™ has been the gold standard for over two decades. Purpose-built for the unique challenges of national security environments, INTERCEPTOR^NX delivers...

Power is the lifeblood of modern data centers — and few components are more critical than thebusway systemsthat distribute that power throughout the facility. As workloads increase and densities rise, even a minor thermal issue in a busway joint or tap-off point can quickly...

Recently, Congressman Pat Harrigan (NC‑10), a decorated Green Beret combat veteran and staunch advocate for national security, visited Network Integrity Systems (NIS) at their headquarters in Hickory, North Carolina. His visit highlighted the vital role of U.S.-developed technology...

When securing classified or mission-critical networks, scale should never come at the expense of performance. One of the most common challenges with traditional fiber optic sensing systems is “range anxiety”—the fear that signal degradation over long distances or across complex...

Effective perimeter security in today’s world demands more than just fences and cameras—it requires a comprehensive, multi-layered approach with cutting-edge technology at its core. At the forefront of this advancement is fiber optic sensing, which transforms traditional security...
