Best warehouse security companies in San Antonio (2026)
San Antonio sits on the I-35 NAFTA corridor — the busiest overland trade artery between the U.S. and Mexico — and that geography defines its warehouse market: cross-border freight from Laredo, the supplier park feeding Toyota's south-side truck plant, and the redeveloped logistics campuses at Port San Antonio and the old Kelly airfield all move product around the clock. Securing a warehouse here means knowing whether a load is bonded cross-border freight needing tight chain-of-custody or routine consumer distribution off the interstate, and the best agency staffs each with the right posture rather than a generic guard.
Calvis is not a security agency and is not itself licensed. We vet and match independently-licensed warehouse and logistics security agencies across Bexar County so you can compare qualified options in one place. We confirm each agency's Texas licensing, insurance, and experience with comparable distribution, cross-border, and manufacturing-supplier clients before connecting you — from a single dock in the Medical Center area to a Toyota supplier facility on the south side. You hire the agency directly; we make sure every option has already cleared a real bar.

Inside warehouse & logistics security in San Antonio
San Antonio's logistics backbone is the I-35 corridor running south to Laredo and the World Trade Bridge, which makes the city a primary staging point for cross-border and bonded freight moving deeper into Texas. The Toyota Motor Manufacturing plant on the south side anchors a dense supplier and just-in-time logistics park, while Port San Antonio — built on the former Kelly Air Force Base — has become a major aerospace, defense-logistics, and distribution campus, and newer e-commerce DCs have filled in along I-35 and Loop 410. Agencies covering these sites navigate a mix of military-adjacent and federally tied facilities at Port San Antonio, the security expectations of automotive just-in-time delivery where a stalled trailer halts a production line, and Texas DPS standards across all of it — coordinating with SAPD and, near the port, with the federal tenants' own controls.
Matched to
what you need.
Security needs aren't one-size-fits-all. The San Antonio 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
Gate officers handle the bonded and cross-border trailers staging off the I-35 corridor from Laredo, verifying seals and driver paperwork at the dock so customs-sensitive freight keeps a clean record — and so the just-in-time loads bound for the Toyota supplier park aren't held up at the fence.
- Ideal for
- Cross-border, bonded, and just-in-time DCs along the I-35 corridor
- Coverage
- South Side (Toyota corridor), I-35 South, Port San Antonio
Yard & Perimeter Patrol
Patrol of trailer yards and fence lines around the Loop 410 and far-south industrial parks, where large staging lots holding cross-border trailers overnight and stretches of undeveloped adjacent land make trailer break-ins and cargo tampering the recurring exposure.
- Ideal for
- Trailer-staging yards and large-footprint sites with overnight loads
- Coverage
- Loop 410, South Side, East Kelly, Southton
Cargo & Inventory Loss Prevention
Loss-prevention coverage for the automotive components feeding the Toyota line and the aerospace and defense-logistics inventory at Port San Antonio, where high-value, traceable parts and federally connected freight make targeted and internal theft a costlier risk than ordinary shrink.
- Ideal for
- Automotive supplier, aerospace, and defense-logistics warehouses
- Coverage
- Port San Antonio, South Side supplier park, Brooks
Remote Video & Alarm Monitoring
Verified camera monitoring and alarm response for the standalone DCs along I-35 South and Loop 410 that sit dark between shifts, screening alarms on-site to avoid SAPD false-alarm fees while catching the real overnight intrusions that hit isolated cross-border staging yards.
- Ideal for
- Single-tenant warehouses without round-the-clock on-site staff
- Coverage
- I-35 South, Loop 410, Southton, East Side
Access Control & Badge Management
Badge issuance, visitor logging, and credential audits for the multi-tenant and federally tied buildings at Port San Antonio, where defense-logistics tenants and a rotating supplier-and-contractor workforce make documented control over who reaches each dock a federal-grade requirement.
- Ideal for
- Port San Antonio tenants and multi-tenant DCs with strict access rules
- Coverage
- Port San Antonio, Brooks, USAA-area campuses, South Side
A real bar,

Tracked reliability record

Common
questions
We confirm active Texas licensing, current insurance, and a real track record with comparable sites — Toyota supplier-park logistics, Port San Antonio defense distribution, or I-35 cross-border cross-docks. We also check whether the agency staffs officers experienced with bonded freight and federally tied facilities before we surface them.
Unarmed warehouse officers in San Antonio typically run $27–42/hr and armed officers $50–80/hr through the agencies we match. Continuous gate coverage on a busy I-35 cross-border yard sits toward the upper unarmed band, while overnight patrol on a quieter Loop 410 site can come in lower. You pay the agency directly.
Yes — every agency is independently licensed through the Texas Department of Public Safety (DPS) Private Security Bureau, with armed officers holding the separate DPS commissioned-officer credential. Calvis is not a security agency and is not licensed itself; we verify the agency's DPS standing so you don't have to chase it down.
The agencies we match for I-35-corridor distribution work routinely staff officers trained in seal verification, BOL checks, and gate-to-dock custody for bonded and customs-sensitive loads staging up from Laredo. We point you to firms with that cross-border experience rather than general commercial guards.
Hiring direct means vetting licensing, insurance, and cross-border or Port San Antonio experience one firm at a time. We've already done that across Bexar County agencies, so you compare pre-qualified options for your specific site and skip the weeks of outreach.
