Security across plant-floor OT/ICS and business IT alike

Houston runs on industries where a technology failure isn't an inconvenience — it's a safety and business event. It's the energy capital of the world, with the majors and a dense Energy Corridor of operators, traders, and service companies. It's home to the Texas Medical Center, the largest medical complex on earth. And it moves the country's freight through the Port of Houston, builds spacecraft around NASA's Johnson Space Center, and refines and ships petrochemicals along the ship channel.
Each of those worlds answers to a different rulebook — OT/ICS safety and IEC 62443 for energy and petrochemical, HIPAA and HITRUST for the Medical Center, CMMC and ITAR for aerospace and defense, and SOC 2 and SOX for the corporate base. Most local IT providers cover business IT and stop at the plant-floor door. intSignal runs managed IT, a 24×7 security operation across IT and OT, cloud, and business communications under one roof — so a Houston company doesn't hand its most critical systems to a vendor who doesn't understand them.
We support businesses across Harris, Fort Bend, and Montgomery counties and the wider metro — The Woodlands, Sugar Land, Katy, Pearland, and out along the ship channel. Senior engineers own your account, and because we operate our own geo-redundant infrastructure across three regions, we can place workloads where performance, cost, and compliance line up — and keep your recovery copy well clear of the Gulf Coast.
The services where being local actually changes the outcome — the region your data lives in, latency, on-site speed, the local climate, and a local phone number.
Houston's biggest sectors carry the highest stakes. We lead every engagement with the obligation that matters to you.
Instead of juggling a helpdesk, a security firm, a cloud reseller, and a phone company, one team owns it all. When something breaks, there's one number to call and one team responsible — with real stake in keeping your business.
Most providers stop at the plant-floor door. We secure business IT and operational technology alike — OT/ICS, SCADA, and the systems that run energy, petrochemical, and manufacturing sites — with people who understand both.
We run geo-redundant enterprise hosting across three regions, so we can place each workload where performance, cost, and compliance line up — and keep your recovery copy well clear of the Gulf Coast.
Remote-first for speed, with local technicians across the Houston metro for hands-on work — and disaster recovery designed for a region where hurricanes and flooding are a regular threat, not a rare one.
Tell us your stack and priorities — we return scope, ownership, and a plan, at no cost.
A complete outsourced IT department for Houston businesses — or a co-managed extension of the team you already have.
A 24×7 security operation and the compliance work Houston's regulated industries actually need — run by senior analysts, not an alert forwarder.
Public, private, or hybrid — placed where performance, cost, and compliance line up, on infrastructure we run across three regions.
Put data and AI to work — automation, analytics, and vision that improve how Houston teams operate.
Replace an aging phone system with a cloud platform that travels with your team — voice, texting, video, and mobile, with AI built in.
The software that runs it all — our own security, network, and operations platforms, available managed or co-managed.
A short, low-risk path from first call to a running, monitored environment.
We map your Houston environment across IT and OT — plant-floor systems included — and the compliance you carry, from HIPAA to CMMC to OT safety, at no cost.
A clear roadmap that treats resilience as a requirement, not an afterthought — because on the Gulf Coast, a major storm is a when, not an if.
We secure and stabilize first — identity, backups with an out-of-state copy, endpoints, and monitoring across both IT and OT.
24×7 operations, a named team, and quarterly reviews that keep you audit-ready and storm-ready.
On-site support across Harris, Fort Bend, and Montgomery counties — the greater Houston metro, including the fast-growing suburbs and the ship-channel communities.
Yes. We're remote-first for speed, but we dispatch engineers across Houston, Harris, Fort Bend, and Montgomery counties — The Woodlands, Sugar Land, Katy, Pearland, and along the ship channel — for hands-on work like installs, cabling, hardware, and new-office builds.
Yes — it's a core Houston engagement. We segment the plant floor from IT, monitor OT networks, align to IEC 62443, and design controls so safety and production always come first. We cover both your business IT and your operational technology.
Yes. We deliver HIPAA- and HITRUST-aligned managed IT and security for healthcare — EHR support and uptime, encrypted and immutable backup, managed detection and response, tight access control, and audit-ready documentation.
Backups run locally for fast restores and are automatically replicated to a second region well outside Texas — off the ERCOT grid and clear of Gulf Coast storms and flooding. So a hurricane, flood, or grid failure can't take out both your systems and your recovery copy.
Yes. Our UCaaS platform is a full cloud phone system — calls, business texting, video meetings, a contact center, and business cellular — with AI transcription and IVR. We provision local 713, 281, and 832 numbers, port your existing lines, and you can keep desk phones, go fully mobile, or both.
From small and mid-sized organizations — roughly 20 to 500 staff — to their compliance-heavy suppliers, plus multi-site and relocating companies. Our IT, OT security, and cloud scale up cleanly as you grow and add locations.
