When Rifles Are the Threat, Standard Glass Fails

The right level depends on your documented threat profile, but for utility substations, power plant security windows, and 911 dispatch centers in the United States, UL 752 Level 7 or Level 8 is typically the appropriate specification. Level 7 is rated for five shots from a 5.56mm rifle - the type used in several recent U.S. substation attacks. Level 8 steps up to five shots from a 7.62mm rifle. Lower levels stop handgun rounds, which is meaningful protection in many settings, but does not address the rifle-caliber threat that has characterized attacks on U.S. grid infrastructure. We can walk through your specific facility and threat assessment to help you land on the right level - one that is neither under-specified nor unnecessarily over-built for your situation.

NERC CIP-014 requires that covered utilities conduct a physical security risk assessment of their transmission stations and substations and implement a documented physical security plan to address identified risks. The standard explicitly recognizes ballistic protection as a valid mitigation measure. Whether it is required at your specific facility depends on your risk assessment findings and the threats identified - but if your assessment identifies gunfire as a credible risk (which DHS and DOE threat bulletins consistently indicate it should be for many U.S. utilities), then ballistic protection is not optional under a compliant security plan. Our UL 752-certified systems provide the documented, independently tested performance that regulators look for when reviewing those plans.

Yes, and this is one of the most common concerns we hear from utility operators and data center managers across the United States. Control room operators need clear sightlines. Customer service staff need to interact with the public. The facility cannot go dark for weeks during an installation. Our systems are custom-engineered to fit the existing architectural layout of your facility, which means they integrate into your space rather than forcing your operations to work around them. Transaction windows maintain communication functionality. Ballistic glazing maintains visibility. And because our systems are manufactured as ready-to-assemble assemblies, installation is significantly faster than field-fabricated alternatives, minimizing operational disruption.

There is no such thing as bulletproof. Every ballistic protection system is rated to resist a specific type and number of rounds at a specific velocity - that is what UL 752 testing measures. The term "bulletproof" is marketing language, not a testable standard. When you see it used without a corresponding UL 752 level or NIJ rating, you are looking at an unverifiable claim. This distinction matters for critical infrastructure buyers in the United States because regulatory bodies, insurance carriers, and legal counsel all want to see documented, independently tested performance - not manufacturer assertions. Our systems are certified to UL 752 Levels 1 through 10 and NIJ Levels I through III, with third-party test documentation you can include in your NERC CIP compliance plan.

Data centers present a specific set of integration challenges that typical security glazing vendors are not equipped to handle. Your HVAC system, fire suppression, cable management, and access control infrastructure all have to coexist with the ballistic barrier - and in many cases, the barrier has to be designed around those systems rather than the other way around. We custom-engineer every system to the specific facility layout, which means we can accommodate the environmental and infrastructure constraints that data centers impose. For data center security barriers across the United States, we typically work from architectural drawings provided by the project team and engineer the ballistic assembly to fit within the existing building envelope without compromising the facility's critical systems.

For many critical infrastructure operators in the United States, it makes a significant difference. Federal procurement preferences under Buy American requirements apply to a wide range of government-adjacent and federally funded projects. Beyond compliance, domestic manufacturing eliminates the international shipping delays and foreign supply chain risks that have disrupted infrastructure projects in recent years. Every system we manufacture is built in West Islip, New York - which also means our engineering team is accessible throughout the project, lead times on custom work are not subject to overseas logistics, and there is no ambiguity about where your ballistic system was made or who stands behind it. For facilities with federal funding, that domestic origin is often not a preference - it is a requirement.
