OT + IP
Plant-floor OT/ICS and trade-secret IP for auto & manufacturing
Detroit is the capital of how the world moves. General Motors, Ford, and Stellantis are headquartered here, wrapped in one of the deepest automotive supplier and engineering bases anywhere — Tier-1 suppliers, tooling shops, and the mobility and autonomous-vehicle labs building what comes next. The region also anchors the Army's ground-vehicle programs (TACOM and the defense-vehicle base), a broad manufacturing economy, and major health systems. It runs on plant floors, valuable IP, and connected operations.
Each of those worlds answers to something specific — OT/ICS security and IP protection for the automakers and their supply chain, CMMC and ITAR for the defense-vehicle base, HIPAA for healthcare, and the quality standards manufacturing demands. Most local IT shops 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 — with people who understand both the plant floor and the boardroom.
We support businesses across Wayne, Oakland, and Macomb counties and the wider Detroit metro. 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 outside the Great Lakes storm zone.
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.
Automotive, defense-vehicle, and manufacturing carry the highest stakes here. 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 the operational technology behind automotive and manufacturing sites alike — OT/ICS, trade-secret IP, and the plant floor — 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 outside the Great Lakes region.
Remote-first for speed, with local technicians across Metro Detroit for hands-on work — and DR designed for a region of lake-effect snow, ice, and flooding.
Tell us your stack and priorities — we return scope, ownership, and a plan, at no cost.
A complete outsourced IT department for Detroit businesses — or a co-managed extension of the team you already have.
A 24×7 security operation and the compliance work Detroit'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 Detroit 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 Detroit environment across IT and OT — plant-floor systems included — and the compliance you carry, from OT security and IP to CMMC and HIPAA, at no cost.
A clear roadmap prioritized by the OEM security requirements, assessments, and IP protections that matter most, with resilience built in for Great Lakes weather.
We secure and stabilize first — identity, backups outside the Great Lakes, 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 Wayne, Oakland, and Macomb counties — the wider Detroit metro, including the automotive and engineering corridors in the suburbs.
Yes. We're remote-first for speed, but we dispatch engineers across Wayne, Oakland, and Macomb counties — Dearborn, Troy, Warren, Auburn Hills, and Southfield — for hands-on work like installs, cabling, hardware, and new-office builds.
Yes — it's a core Detroit engagement. We secure cleanroom and plant-floor OT/ICS, segment operational systems from IT, protect trade-secret IP, and meet the security requirements the OEMs push down onto suppliers, so production comes first.
Yes. Around the Army's ground-vehicle programs, we assess against NIST 800-171, close the gaps, protect CUI, build your SSP and POA&M, and handle ITAR — running the monitoring assessors expect for CMMC 2.0.
Backups run locally for fast restores and are automatically replicated to a second region well outside the Great Lakes region — clear of the area's storms, flooding, and grid strain. So a storm or outage 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 313, 248, and 734 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 growing companies. Our IT, OT security, and cloud scale up cleanly as you grow and add locations.
