Protecting your property and supporting 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 operational presence serving 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, supporting 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 address issues before they escalate.
From healthcare facilities and construction sites to retail, commercial, and residential properties, we design security solutions around real-world risk rather than fixed staffing models. Whether through proactive patrol routes or selective on-site coverage, our approach emphasizes visibility, prevention, and reliability.
Contact Diligence Security to experience a security presence built to support your business—focused, responsive, and dependable.
