Security Guard Service You Can Rely On — Nationwide

At Nationwide Security Service, we provide professional security guard service solutions across the United States. Our licensed, insured, and highly trained officers protect businesses, construction sites, commercial properties, and special events — delivering peace of mind through reliable on-site security.

We don’t just offer coverage — we provide protection that performs.

From the moment our guards step onto your property, you’ll notice the difference. Each officer is carefully vetted, background-checked, and equipped with the training needed to adapt to your site’s specific demands. Whether it’s a retail center in Los Angeles, a warehouse in Miami, or a high-rise in Boston, our team arrives on time, in uniform, and ready to protect.

As a leading national security guard service, we believe that consistency is key. That’s why we maintain 24/7 communication through our centralized dispatch center and GPS-tracked patrols, giving you full visibility into your security operations at all times. Our services are never one-size-fits-all — we tailor every detail to meet your location’s risk profile, hours of operation, and unique challenges.

When clients choose Nationwide, they’re choosing more than guards — they’re choosing a partner who is invested in safety, compliance, and reputation management. Whether you need short-term event security or a long-term guarding solution, we deliver unmatched professionalism with every shift.

"I knew I should have trusted my gut and not gone with the "bargain" security company. They cancelled on me last minute. Called Nationwide and they confirmed with me right away, relieving my stress! Will be calling them FIRST next time"
