About Nexus Core

Purpose-built for facilities where failure is not an option.

Nexus Core Security Group LLC (NCSG) is a specialized physical security firm built for the environments the digital economy depends on: data centers, colocation facilities, hyperscale campuses, and critical infrastructure operations.

Who We Are

Data centers aren't office buildings.

They are high-value, high-consequence facilities housing the digital backbone of commerce, government, and national security. We understand that reality at the operational level. Our programs are purpose-built for Tier I–IV data center environments — layered access control, mantrap and tailgating prevention, 24/7 GSOC-integrated monitoring, and compliance-ready documentation that stands up under SOC 2 Type II audit scrutiny.

Nexus Core is a certified Veteran-Owned Small Business (VOSB) and Service-Disabled Veteran-Owned Small Business (SDVOSB), headquartered in San Antonio, Texas, with mission support centers across the country's major infrastructure markets.
