Best warehouse security companies in Seattle (2026)
Warehouse security in Seattle is really port logistics security wearing a different hat — most of the region's distribution buildings exist to feed or drain the container terminals on Harbor Island and the Duwamish, and the cargo moving through them is on a clock the tide and the rail schedule set. The best company for a SoDo cross-dock handling import freight off the Port of Seattle is reading a different risk picture than one guarding a South Lake Union last-mile depot serving the downtown core, and a good match depends on whether your building lives or dies by container throughput.
Calvis is not a security agency and is not itself licensed. We vet and match independently-licensed warehouse and logistics security agencies across the Puget Sound region so you can compare qualified options in one place. We confirm each agency's Washington State Department of Licensing security registration, insurance, and experience with port-adjacent and maritime-logistics sites, then connect you directly with the ones that fit your operation — from a single Kent Valley fulfillment building to a portfolio spanning SoDo and the Duwamish. You hire the agency yourself; we make sure every option you see has already cleared a real bar.

Inside warehouse & logistics security in Seattle
Seattle's warehouse geography is a corridor problem: the SoDo and Georgetown industrial district between downtown and the container terminals, the Harbor Island and Duwamish River freight blocks that feed the Port of Seattle, and the sprawling Kent Valley distribution belt south along Interstate 5 and Highway 167. Cargo theft here clusters where containers sit waiting — drayage yards, intermodal staging, and the chassis lots that fill up when terminal gates back up. Agencies are expected to work around the rhythms of port operations and the Northwest Seaport Alliance, coordinate with Seattle PD's response in an industrial zone that empties at night, and account for a Pacific Northwest reality where weeks of wet, dark winter make perimeter visibility and reliable patrol coverage harder than the daylight months suggest.
Matched to
what you need.
Security needs aren't one-size-fits-all. The Seattle network spans these warehouse & logistics security specialties — tell us what you need and we match you to the agencies built for it.
Truck-Gate & Dock Access Control
Officers control the gate for SoDo and Duwamish buildings that turn drayage off the Port of Seattle, verifying driver, container number, and seal against the appointment before a chassis crosses the line. When terminal gates back up and trucks queue, gate officers keep the staging orderly so a congested yard doesn't become an opportunity for a wrong-container pull.
- Ideal for
- Port-adjacent drayage operations, import/export cross-docks, and intermodal-fed distribution buildings
- Coverage
- SoDo, Harbor Island, Duwamish industrial district, Georgetown
Yard & Perimeter Patrol
Roving patrol of the chassis lots and trailer yards strung along the Kent Valley belt and Interstate 5, checking container seals and lot fencing through the long, wet Northwest nights when visibility drops and isolated drop-lots tempt cargo crews. Patrol routes are timed to the gaps when drivers are gone and the next shift hasn't arrived.
- Ideal for
- Kent Valley distribution yards, chassis and container drop-lots, and large fenced freight parcels
- Coverage
- Kent Valley (Kent, Auburn, Tukwila), South Park, I-5 freight corridor
Cargo & Inventory Loss Prevention
Loss-prevention officers focused on the moment imported goods break bulk — the point in a Georgetown or SoDo building where a sealed container becomes loose pallets and pilferage gets easy. Coverage targets break-bulk staging, high-value import SKUs coming off the terminals, and the reconciliation between what a container manifest promised and what actually lands on the rack.
- Ideal for
- Import-heavy 3PLs, break-bulk operations, and distributors handling containerized consumer or retail goods
- Coverage
- Georgetown, SoDo, Interbay, Ballard industrial
Remote Video & Alarm Monitoring
Live camera monitoring and verified alarm response tuned for Seattle's dark winters, when a wet, unlit yard reads poorly on standard cameras and after-hours intrusions go unseen. Monitoring covers the South Lake Union and Interbay last-mile depots that don't run an overnight post, with an officer verifying before Seattle PD is dispatched.
- Ideal for
- Last-mile depots, smaller single-tenant warehouses, and flex-industrial sites without 24/7 staffing
- Coverage
- South Lake Union, Interbay, Fremont industrial, Ballard
Access Control & Badge Management
Officers manage badge issuance, driver check-in, and contractor escort for the multi-tenant logistics buildings of the Kent Valley, where longshore-adjacent labor, temp pickers, and a rotating cast of carriers move through shared docks every shift. The result is a defensible record of who entered a port-fed building and when — useful when a container comes up short.
- Ideal for
- Multi-tenant Kent Valley parks, shared cross-docks, and sites with heavy carrier and temp turnover
- Coverage
- Kent, Auburn, Tukwila, Renton industrial parks
A real bar,
not an ad auction.
Every agency in Seattle clears the same four checks before it can take warehouse & logistics security work. Licensing is verified through the Washington State Department of Licensing — Security Guard Program.
State licensing verified
Every agency holds an active state security license. We confirm it before any agency can take work.
Active insurance on file
Current general-liability (and where applicable, workers' comp) coverage is verified, not assumed.
Background-checked officers
Agencies field licensed, background-checked guards — the people who actually show up on site.
Tracked reliability record
Shift-reliability is measured on the platform. Agencies that no-show or slip on coverage are removed.
What warehouse & logistics security costs in Seattle
Standard posts, patrol, and monitoring. Recurring contracts are typically priced below on-demand rates.
Coverage where an armed presence is warranted. Rates vary with risk profile and shift length.
Final pricing depends on site, hours, number of officers, and whether you need a static post or mobile patrol. Get a firm quote by requesting a match above.
Common
questions
We verify each agency's registration with the Washington State Department of Licensing Security Guard Program, confirm general-liability and workers'-comp insurance, and review their experience with port-adjacent, maritime, and Kent Valley logistics sites. Only agencies that clear that bar reach your shortlist, so every option you compare is already qualified to staff a Puget Sound distribution building.
Unarmed warehouse guards in Seattle typically run about $33–52 per hour and armed officers about $58–95 per hour, depending on shift length, the number of gate and patrol posts, guard experience, and whether the site sits inside a port-security perimeter. Round-the-clock coverage of a drayage yard or import cross-dock trends toward the upper end of that range.
Yes — every agency Calvis matches you with is registered through the Washington State Department of Licensing Security Guard Program, which regulates security guard companies statewide. Calvis itself is not a licensed security provider; we connect you with independently-licensed agencies and verify that registration as part of our vetting.
Yes. Many of the Puget Sound agencies we vet work daily around drayage and intermodal rhythms — seal verification on containers off the Port of Seattle, break-bulk loss prevention, and gate control when terminal congestion backs trucks into the yard. When you compare agencies you can ask specifically for officers experienced with port-adjacent and containerized freight.
Hiring directly means cold-calling agencies and taking their licensing, insurance, and port-logistics experience on faith. Calvis lets you compare multiple pre-vetted Seattle logistics agencies side by side — Washington registration confirmed, references checked, rates transparent — so you reach a qualified shortlist in days instead of weeks, and still hire the agency directly yourself.
