Best school security companies in Houston (2026)
The best school security company in Houston is built for scale, heat, and a campus footprint that stretches across one of the most spread-out metros in the country. Houston ISD is the largest district in Texas, with hundreds of schools ranging from historic inner-loop campuses to newer suburban-style buildings on large lots, and it sits alongside fast-growing surrounding districts, a deep private and faith-based sector, and major universities like the University of Houston and Rice. Texas school-safety law now requires an armed officer presence at every campus, which has reshaped how districts staff security and pushed many toward outside partners to meet the mandate. The right partner understands both that legal requirement and the day-to-day reality of large, hot, car-dependent campuses.
Calvis is not a security agency and is not itself licensed. Instead, we vet and match independently-licensed school and campus security agencies across the Houston area so you can compare qualified options in one place. We screen each agency's licensing, insurance, and experience with comparable Texas schools and universities, then connect you directly with the agencies that fit your campus footprint, your staffing mandate, and your budget. The hiring decision is yours. We make sure every agency you see has already cleared a genuine standard.

Inside school and campus security in Houston
Houston's school security market has been reshaped by Texas House Bill 3, which requires an armed officer or guardian at every campus, making consistent armed coverage a baseline rather than an exception and driving districts to lean on commissioned officers from outside agencies to fill gaps the district cannot staff alone. The metro's scale and heat shape everything else: campuses are large and horizontal, students arrive overwhelmingly by car or bus, and arrival and dismissal play out across wide drop-off loops and parking lots in often punishing weather. Houston ISD spans dense inner-loop schools and sprawling outer campuses, while surrounding districts add fast-growing suburban schools on large tracts. The private and parochial sector manages its own perimeters, and universities like UH and Rice run open campuses with dorms, research buildings, and large athletic venues. Flooding and severe-weather preparedness factor into emergency planning across the region. Agencies working here are expected to staff state-commissioned armed officers where required, manage heat-aware outdoor posts, control large perimeters, and coordinate closely with district police departments and administration.
Matched to
what you need.
Security needs aren't one-size-fits-all. The Houston network spans these school and campus security specialties — tell us what you need and we match you to the agencies built for it.
Commissioned Armed Officer Posts (HB 3 Coverage)
State-commissioned armed officers posted to satisfy Texas's per-campus armed-presence requirement, supplementing or filling in for district police where the district cannot staff every building. Officers hold the required Texas commission and work within the district's safety chain of command.
- Ideal for
- Districts and private schools meeting the per-campus armed-officer mandate
- Coverage
- Houston ISD campuses, suburban district schools, private schools across the metro
Single-Point Entry & Access Control
Officers enforce a single controlled point of entry, manage badge-in and vestibule screening, and keep secondary doors and gates secured during the school day. On large campuses this anchors access control while patrol covers the rest of the footprint.
- Ideal for
- Inner-loop and suburban schools relying on a controlled main entrance
- Coverage
- Inner-loop HISD schools, suburban district buildings, parochial campuses
Bus, Drop-Off & Heat-Aware Arrival Control
Coverage for the wide bus loops and car drop-off lanes typical of Houston campuses, with officers directing traffic, keeping crosswalks safe, and managing arrival and dismissal across large lots in heat and sudden storms. Outdoor posts are scoped with the weather in mind.
- Ideal for
- Large suburban-style campuses with bus loops and extensive parking
- Coverage
- Outer-loop and suburban drop-off loops, bus lanes, large-lot dismissal zones
Large-Campus & Perimeter Patrol
Roving officers cover the long fence lines, athletic fields, portables, and parking areas of sprawling Houston campuses that a single fixed post cannot watch, catching breaches and unauthorized access across the full property.
- Ideal for
- Horizontal high schools and large campuses with fields, portables, and big lots
- Coverage
- Suburban high-school grounds, athletic complexes, multi-building campuses
University Building, Dorm & Event Coverage
Officers manage card-access buildings, residence-hall desks, and event security across open university campuses, plus large athletic and performance venues. Coverage controls dorm and lab access while keeping the campus welcoming.
- Ideal for
- University of Houston, Rice, and other campuses with dorms and large venues
- Coverage
- UH and Rice-area buildings, residence halls, university stadiums and arenas

Common
questions
We confirm each agency holds active Texas licensing through the Department of Public Safety Private Security Bureau, verify general-liability and workers'-comp coverage, and review their experience with comparable Texas schools and universities along with references. For armed posts we also confirm officers hold the required state commission. Only agencies that clear that bar reach your shortlist.
Yes. Many districts and private schools use outside agencies to supply state-commissioned armed officers where district police cannot cover every campus, which is the core of the current Texas mandate. Agencies we vet can staff commissioned officers who work within your safety chain of command, and you can pair that with unarmed coverage for access control and patrol as needed.
Yes. Houston campuses are big, horizontal, and car-dependent, so agencies here are used to running bus and drop-off loops, patrolling long perimeters, and scoping outdoor posts around heat and sudden storms rather than just watching a front door. Coverage is built around your specific lots, gates, fields, and bell schedule when you compare agencies.
Yes. Every agency Calvis matches you with holds its own active license through the Texas Department of Public Safety Private Security Bureau. Calvis itself is not a licensed security provider. We connect you with independently-licensed agencies and verify that licensing as part of our vetting.
