Diligence Security: Your Partner for Comprehensive Security Solutions
Protecting your property—and your peace of mind—is our focus. Diligence Security provides professional security services along Meridian Avenue and throughout Tacoma, Seattle, Pierce County and King County, with a strong presence supporting businesses from downtown Puyallup through South Hill.
We specialize in highly visible patrols and rapid response for commercial and unoccupied properties. Our Officers receive substantially more training than industry standards, resulting in heightened awareness, disciplined decision-making, and dependable response when it matters most. Marked patrol vehicles reinforce a consistent deterrent presence along the Meridian corridor, helping prevent issues before they escalate.
From healthcare facilities and construction sites to retail, commercial, and residential properties, we design security solutions around real-world risk—not one-size-fits-all staffing. Whether through proactive patrol routes or selective on-site coverage, our approach emphasizes prevention, visibility, and reliability.
Contact Diligence Security today to experience a security presence built for your business needs—focused, responsive, and designed to support safer environments.
