Managed IT, Cybersecurity & Compliance Services in Houston, Texas

Armorstack operates as a service-area provider in Houston and dispatches engineers across Harris County, Fort Bend County, Montgomery County, Brazoria County, Galveston County, and the broader Greater Houston area for scheduled and emergency on-site work, with target response of 4 hours during business hours and 8 hours overnight. Our 24/7 SOC monitoring and vCISO/vCIO engagements are delivered with no geographic gap and full Central Time alignment. Reach our Greater Houston desk at 877-890-5508.

Yes. Our SENTRY OT practice operates in Modbus, DNP3, OPC UA, and IEC 61850 environments common across the Energy Corridor and the Houston Ship Channel petrochemical complex. We deliver TSA Pipeline Security Directive (SD02C and successors) readiness, API 1164 SCADA hardening, NERC CIP for grid-adjacent assets, and IEC 62443 industrial control system security. SOC visibility is engineered for OT / IT convergence — IT-only SIEMs do not survive contact with a Halliburton, Phillips 66, or Occidental SCADA environment, and ours is built for both. Call 877-890-5508 to scope.

For an active incident with a service retainer in place, our incident response team is engaged within 30 minutes via SOC and on-site within 4-8 hours depending on time of day. We coordinate directly with the FBI Houston Field Office at 1 Justice Park Drive, CISA Region 6, the US Coast Guard Sector Houston-Galveston for port-and-maritime incidents, and the Texas Department of Public Safety Cybercrime Unit. We file Texas Attorney General data-breach notifications within the 30-day deadline triggered when 250 or more Texans are affected.

We do not represent those institutions, but our team has extensive HIPAA, Texas HB 300, Epic, and Cerner / Oracle Health experience and works with their suppliers, specialty vendors, business associates, and adjacent providers across the Texas Medical Center’s 61 member institutions. Our healthcare practice is built around the workflows and compliance frameworks Tier-1 academic medical centers and TMC-anchored research institutes impose on partners and downstream covered entities.

Yes. Armorstack delivers CMMC Level 1 and Level 2 implementation and assessor coordination for Defense Industrial Base contractors and NASA-adjacent space-systems suppliers across Greater Houston, with particular attention to ITAR, EAR, NIST 800-171, NDAA Section 889, and the NASA FAR Supplement (NFS) for direct NASA contracts. Our VERITY portfolio includes a credentialed CMMC practice that has prepared clients for first-attempt Level 2 certification. We coordinate with C3PAOs to deliver assessment-ready environments for the Clear Lake aerospace cluster.

Yes. TDPSA became effective July 1, 2024 and is enforced exclusively by the Texas Attorney General with civil penalties up to $7,500 per violation after a 30-day cure period. We help Houston mid-market firms map TDPSA controller and processor obligations, consumer rights workflows (access, deletion, correction, opt-out of sale and targeted advertising), data protection assessments, and the small-business carve-out. TDPSA layers on top of existing federal frameworks; our practice integrates it into your NIST CSF 2.0 program rather than treating it as a stand-alone effort.

Managed IT engagements for 100-500 employee Houston firms typically run $9,000-$35,000 per month depending on scope. Energy and OT-heavy environments range higher because of OT-specific SOC tooling and engineer hours. vCISO and VERITY Compass retainers add $3,500-$12,000 per month. SOC monitoring is priced per asset. Most clients start with a fixed-fee assessment under $20,000 to establish scope before committing to ongoing services. Many Houston firms begin with our 90-day no-contract assessment.

Yes. Our CITADEL portfolio integrates access control, video surveillance, fire alarm monitoring, and low-voltage infrastructure with cybersecurity monitoring across Energy Corridor campuses, Texas Medical Center buildings, port facilities, refining and petrochemical sites, and downtown office towers. We work with NDAA Section 889-compliant equipment for federal-adjacent and defense-supplier engagements. Process-safety-aware physical security is a particular focus for Houston Ship Channel operations. Site surveys are scheduled within 5 business days. Call 877-890-5508.

Houston’s energy, healthcare, and aerospace sectors are deploying AI faster than most security programs can govern them. ExxonMobil, Chevron, Halliburton, MD Anderson, Houston Methodist, and NASA-adjacent contractors are all shipping AI features into regulated, safety-critical workflows. Armorstack’s SENTRY portfolio detects shadow AI, monitors prompt-injection patterns, models OT-AI cyber-physical risk, and integrates AI risk reporting into your existing NIST CSF or NIST AI RMF program. A Shadow AI Discovery typically completes within 5-10 business days.

We work with engagements subject to the Texas Department of Insurance (TDI), Texas Health and Human Services Commission (HHSC), Texas Department of State Health Services (DSHS), Texas Railroad Commission (RRC) for energy-sector oversight, Texas Department of Banking, the Texas Attorney General (TDPSA / Identity Theft Enforcement and Protection Act enforcement), and Texas Department of Information Resources (DIR). Federal regulators with strong Houston footprint include the FBI Houston Field Office, CISA Region 6, TSA Surface Transportation Security, and the US Coast Guard Sector Houston-Galveston.

Yes. HB 300 expands the federal HIPAA covered entity definition to any entity that creates, receives, maintains, or transmits PHI in Texas — including business associates, schools, governmental units, and information-management vendors. The Texas Medical Center supply chain is heavily affected. Our HB 300 practice covers the 90-day employee training requirement, 15-business-day patient record access for EHR-using providers, restrictions on PHI sale, and electronic-disclosure authorization workflows. We integrate HB 300 controls with HIPAA Security Rule, HITECH, and Texas Identity Theft Enforcement and Protection Act notification.

Schedule a 30-minute discovery call at armorstack.ai/contact/ or call 877-890-5508. The call is candid scoping — no pitch deck. If we agree there is a fit, the typical first engagement is a fixed-fee assessment with a defined deliverable in 4-6 weeks before any monthly retainer commitment. Many Houston firms start with our 90-day no-contract assessment.
