Zero-trust remote access, without touching production.
Half of 2025 manufacturing breaches started with RDP or VPN misconfiguration. This 2-page diagram shows the typical legacy sprawl on page 1 and what zero-trust actually looks like on page 2 — sized for a 100-employee plant, but the principles scale either direction.
- Before/after architecture, side-by-side
- Phased migration path — no production downtime
- Includes engineer, admin, vendor, and OEM access tiers
- Branded but usable on your internal decks

Why this diagram is different
Most zero-trust resources are vendor pitches dressed up as architecture documents. This one isn't. It's the actual reference model our manufacturing IT engineers use when scoping migrations — pulled straight from real client engagements. If you've inherited a VPN sprawl problem you can't see your way out of, this is the read.
Shows legacy and target state side-by-side
Page 1 is the sprawl you probably have today. Page 2 is what good looks like. The contrast is the point.
Four phases, zero forklift migration
Phase 1 keeps existing VPN, Phase 4 decommissions it. Production runs uninterrupted throughout.
Tier-specific access policies
Engineers, admins, contractors, vendors, OEM service techs — each gets a different access model. The diagram shows them all.
Vendor-neutral architecture
Works with whatever you're running today — Cisco AnyConnect, Palo Alto GlobalProtect, FortiClient. The model translates.

Quick FAQ
The questions we get most often about this asset and what comes after.
No. The architecture is vendor-neutral. We have implementations on Cisco, Palo Alto, Fortinet, Zscaler, and Cloudflare Access. The principles apply regardless of which platform you choose.
The principles scale. The diagram is sized for a 100-employee reference plant, but we've used the same model at facilities up to 500 employees and three-plant networks. Larger environments add complexity to phasing, not to the architecture itself.
Yes. It's IT Vortex-branded, but you're welcome to use it in internal decks, board materials, and architecture reviews. We see it referenced in client decks regularly — that's what it's for.
OT-adjacent zero-trust is where most of our manufacturing work lives. The diagram covers IT remote access, but we run a deeper OT engagement on top of it for clients with critical infrastructure exposure. Worth a separate conversation.
