One central console for all your plants, sites, or end customers - secure browser access, granular permissions, audit-grade logs. We build the platform you use to operate your distributed industrial and critical-infrastructure fleet.

Classical tools are designed for individual sessions: a technician connects to a plant, done. As soon as you need to manage hundreds of sites with different end customers, granular permissions, and audit-grade access, those tools start working against you.
A custom platform gives you control over the permission model, the audit format, the branding, and most importantly over data residency - no US SaaS vendor in the tunnel to your critical-infrastructure plant.
These capabilities are already shipping in production industrial platforms we built - we adapt them to your use case instead of starting from zero each time.
Every site connects to your platform through an encrypted, dedicated VPN tunnel. Connectivity is automated, new sites are provisioned in minutes - without on-site configuration.
Technicians and end customers open a tab and they are connected. No client plugin, no VPN software on the device. Works for classical VNC HMIs and modern web HMIs alike.
Per tenant, per site, optionally per device - you decide who sees and does what. End customers get a read-only view of their site, technicians get full control, platform operators see everything.
Every access is logged - who, when, which site, from which IP. During support cases the log shows that an admin acted on behalf of an end customer without losing the original identity. Holds up to NIS2, ISO 27001, and critical-infrastructure audits.
Sites in multiple regions, tenants with their own customers, OEMs with their own sub-operators - all in one platform. Growth does not need architectural renovation, just an additional region or a new tenant.
Plans, schematics, maintenance reports, manuals - stored per site, available in the browser, with clear permissions. Whoever has site access has the documents to hand.
Anywhere hardware sits distributed, must be serviced, and multiple stakeholders need access, a custom platform pays off.
Machine fleets, process plants, water utilities - distributed sites with classical HMIs (Siemens, B&R, Beckhoff, AVEVA). Operator and end customer access via the same portal, with different permissions and a full audit trail.
Energy, water, telecommunications. NIS2 / critical-infrastructure relevant: documented access, traceable audit trail, EU data residency. We deploy on European hosting providers using open-source components.
OEMs selling plants plus ongoing service to end customers. One portal for hundreds of end customers, each with one or more plants - OEM keeps oversight, end customer sees only theirs.
Retail outlets, train stations, ad displays, outdoor terminals - anywhere hardware lives in a foreign environment and must be serviced without on-site visits each time.
ABCO Water Systems operates water treatment plants at distributed remote sites. This became AB-View, a production remote access platform with central HMI access, role-based customer access, session control and auditability.
Read the product case studyWe map your site fleet, your plant landscape, and your compliance duties. Output: an architecture document with permission matrix, scaling assumptions, and migration path.
Implementation in iterative releases - the first real site is typically live after eight to ten weeks. We deliver with documented handover tests and runbooks so your team stays in control at all times.
Optional managed-operations contract: 24/7 monitoring, patch management, new region rollouts. Or handover to your team with detailed documentation.
Scoping Sprint
Requirements, target architecture and effort are clarified. The result is a fixed-price offer for implementation.

Answers to the most important questions
We start with a scoping sprint that clarifies the tenant model, plant types and compliance needs. On that basis you receive a binding fixed price for the platform implementation - predictable, instead of usage-based per-device or per-technician license fees. We agree the concrete scope individually with you.
MVP with one or two site types, permission model and audit: 8 to 12 weeks. Full build with multi-region and multiple plant types: 4 to 8 months. We deliver in iterative releases - the first real site is typically live after 8 to 10 weeks.
Yes. Existing site connections can be adopted and integrated rather than reconfigured from scratch. We migrate in phases - you can run old and new platforms in parallel until the handover is complete.
By default in European data centers (Hetzner, IONOS, OVHcloud, STACKIT) - privacy-focused, NIS2 ready. On request we also operate the platform on your own infrastructure (Proxmox, bare metal) or in a hyperscaler of your choice.
Audit trails are standard - filterable in the UI, exportable for your SIEM or audit reporting. On request we add a reporting module that lets you pull quarterly and annual reports directly from the platform.
Not necessarily. We offer managed operations as a follow-on service: 24/7 monitoring, patch management, new region rollouts, CVE response. So your team stays on core business.
No risk: worst case, you leave with a clearer understanding of your project than before.
“WZ-IT's advice on our Azure migration was technically sound and completely non-binding right from the intro call - we took away a great deal.”

“WZ-IT moved our studio infrastructure from decentralised individual devices to a central platform: every site is securely connected via VPN, new devices are onboarded automatically and an entire site is provisioned from a template, without manual steps on location. What impressed me most is the breadth and depth of their knowledge: Timo and Robin are not a typical IT provider who sets up a server and leaves. The two of them think their way into highly complex infrastructure and software topics, work through every requirement we put in front of them, and build networking, provisioning and operations so that everything fits together in the end. WZ-IT is an excellent partner for complex software, network and architecture projects.”

“Communication with WZ-IT was open, friendly and professional from the very beginning. Mr. Wevelsiep and Mr. Zins responded to every one of our questions patiently, promptly and respectfully, and contributed their own suggestions and good ideas on how to modernize our server infrastructure and adapt it even better to our needs. Throughout, WZ-IT consistently kept our need for data sovereignty and GDPR compliance in mind. Even short-notice adjustments and change requests from our side were implemented quickly and patiently and integrated consistently into the overall concept. From planning to the final handover, every step was documented transparently and comprehensively - so if a provider change should ever become necessary, the documentation would let us onboard a successor into our infrastructure very quickly. We are extremely satisfied with WZ-IT and hope to continue working together for a long time.”

“WZ-IT provided very competent support in implementing our server and virtualization infrastructure. As part of the project, a Proxmox-based virtualization environment was set up along with a virtual machine for our application systems. Additionally, a structured backup concept was implemented. A particular focus was on security: the setup of a VPN tunnel and the clean implementation of encryption and access concepts were professionally executed. The structured consulting as well as the reliable and swift implementation deserve special mention. We are very satisfied with the services provided and are happy to recommend WZ-IT.”
