Around-the-clock coverage is a shift-architecture problem: three shifts, relief planning, and supervision that does not sleep. We run 24-hour posts with built-in relief officers and overnight supervision, so 4 AM coverage is as sharp as 4 PM coverage — and the daily report proves it.

Why Sites Choose National Protective Service
Our clients renew at 99% because the fundamentals never slip: officers show up trained, posts are supervised, and every shift is documented. 24 Hour Security Guard Services is not a line item to us — it is the work our reputation stands on.
Coverage Built Around Your Site
No two properties carry the same risk, so no two coverage plans should look alike. Before the first shift, a licensed professional walks your site, maps entry points and after-hours exposure, and drafts written post orders your team can read and approve. Officers arrive knowing your property — not learning it on your time. As needs change, coverage flexes: extra posts for busy seasons, patrol passes for quiet ones, one contract throughout.
Also Available: security guard staffing agency
If your risk picture includes more than one exposure, security guard staffing agency can run under the same agreement — one supervisor, one reporting format, one invoice. We will scope both in the same assessment visit.
What Drives the Cost
Four things set your rate: the coverage type, the hours you actually need, the site’s risk profile, and the contract term. We scope all four in a free assessment, then quote a firm number — no estimates that drift, no charges that appear later. If patrols or a hybrid plan can protect your property for less than a standing post, that is what we will recommend.
Licensed, Trained, and Accountable
Every post is staffed by California BSIS-licensed officers (PPO 120545), and our team follows professional standards aligned with ASIS International, the leading association for security management professionals; you can verify our California PPO license 120545 directly on the California Bureau of Security and Investigative Services (BSIS) registry. The same documented standard covers uniformed security officers — training, verification, and paperwork you can check, not just claims on a website.
