The Problem

As access grows, classic VPN quickly becomes a risk

Remote work, distributed sites, cloud resources, external service providers and internal platforms all need secure access. Classic VPN setups often grow uncontrolled: too many exceptions, unclear permissions, central bottlenecks and little transparency.

Access is too coarse

A VPN account often opens more network segments than necessary. Roles, groups, devices and specific services are not cleanly separated.

Sites and cloud are fragmented

On-premise, public cloud, private cloud, Proxmox, Kubernetes and individual sites have grown historically and are hard to secure consistently.

Classic VPNs become a bottleneck

Central gateways, manual firewall rules and poorly documented routes make operations, performance and troubleshooting difficult.

Operations and audits are missing

Who can access what? Which devices are connected? Which routes exist? Without monitoring, logs and clear policies, you are flying blind on secure access.

Our Approach

Secure access as part of your infrastructure - not as an isolated VPN

We treat network access not as a single tool, but as a layer of your infrastructure. What matters are identity, devices, routes, policies, monitoring and operations. Depending on the environment, we use NetBird, WireGuard, classic VPNs, firewalls, routing and zero-trust concepts so they fit your systems.

Identity & Devices

SSO, groups, roles, device management and access by user, team or purpose.

Network & Routes

Remote access, site-to-site, network routes, cloud connectivity, internal services and segmentation.

Policies & Security

Least privilege, access to specific systems, MFA, admin access, customer access and auditability.

Operations & Transparency

Monitoring, updates, logs, incident response, documentation and regular review processes.

Typical Projects

What we typically work on

Concrete secure access projects at the intersection of networking, infrastructure and operations.

Remote access for teams and administrators

Secure access to internal systems, admin interfaces, servers, Proxmox, Kubernetes, databases or business applications.

Site-to-site connectivity

Connect multiple offices, sites, plants or edge systems securely via controlled routes.

Cloud and private-cloud integration

Bring public cloud, private cloud, Proxmox, Kubernetes and on-premise systems into a clean access concept.

Remote access for customers and partners

Provide external access to selected systems, portals or plants - without opening the entire network.

HMI and industrial access

Secure access to distributed plants, HMIs, gateways or service systems for operations, maintenance and support.

Replace legacy VPN

Gradually move existing VPN gateways, firewall rules and manual access into a more modern secure access model.

Run NetBird self-hosted

NetBird with your own control plane, SSO, policies, relay/signal servers, monitoring and operations on controlled infrastructure.

Audit VPN and access concept

Review existing access, routes, firewall rules, user groups and operating processes and derive prioritized measures.

Services

From architecture to operations

We do not just set up a VPN tool. We design, integrate and operate secure access as part of your infrastructure.

Secure Access Consulting & Architecture

We clarify which users, devices, sites, services and networks need to be connected - and which model fits technically and organizationally.

NetBird Setup & Self-Hosting

We set up NetBird self-hosted or on European infrastructure, including management service, signal/relay, TLS, DNS and base configuration.

SSO & Identity Integration

Integration with existing identity providers via OAuth/OIDC, groups, roles, MFA and access by teams or responsibilities.

Network Routes & Site-to-Site

We connect existing networks, cloud resources, sites and legacy systems via controlled routes and routing peers.

Policy Design & Zero Trust

Granular access rules by user, device, group, service or network segment - instead of blanket full access to the internal network.

Client Rollout & Migration

Gradual rollout for employees, administrators, service providers or sites with test phases, documentation and a transition concept.

Monitoring & Operations

Monitoring of control plane, relays, routes, availability, updates, certificates and critical access paths.

Security Review & Hardening

Review of firewall rules, access paths, groups, admin permissions, logs, emergency access and operating processes.

Stack & Architecture

NetBird, WireGuard and modern mesh VPNs as building blocks

NetBird is an excellent building block for many secure access scenarios: WireGuard-based, self-hostable, with peer-to-peer connections, NAT traversal, central management, policies and network routes. We use NetBird where it fits the security, operations and infrastructure model - and combine it with firewalls, routing, SSO, monitoring and existing network components where needed.

Self-hosted Control Plane

Management stays under your control - on your own infrastructure or hosted in Europe.

WireGuard-based Connections

Modern, high-performance tunnels for devices, sites and internal services.

Network Routes

Connect existing networks without installing a client on every system.

Policies & Groups

Structure access by teams, roles and services.

Relay & NAT Traversal

Enable connections even in more complex network environments.

Operations & Monitoring

Keep updates, availability, routes, certificates and critical components in view.

NetBird architecture overview

NetBird architecture: management, signal and relay as a self-hosted control plane, WireGuard connections between peers.

Architecture Models

Typical secure access architectures

Five models we implement again and again in projects - individually or combined.

Remote access for teams

Employees and administrators access internal services, servers, dashboards or admin interfaces - with SSO, groups and device context.

Site-to-site & branch connectivity

Sites, cloud resources and on-premise networks are connected via routing peers and controlled routes.

Privileged access for operations teams

Admin access to Proxmox, Kubernetes, databases, firewalls or internal systems is deliberately restricted and made traceable.

Customer & partner access

External users get access to selected services or plants without opening your entire network.

Cloud & hybrid infrastructure

AWS, Azure, European cloud, private cloud and on-premise systems are connected via unified access and routing concepts.

Honest Assessment

Not every access scenario needs a mesh VPN

We only recommend NetBird or a comparable mesh VPN when it fits the infrastructure, the team and the operating model.

A mesh VPN makes sense when:

  • multiple users, devices or sites need to be connected securely
  • classic VPN gateways become a bottleneck
  • access should be controlled more finely than "in the VPN or not"
  • cloud, private cloud and on-premise systems need to be connected
  • external service providers or customers need limited access
  • self-hosting and data control matter
  • operations, monitoring and clear policies are wanted

A mesh VPN is often not the best solution when:

  • only a single server needs to be administered
  • no ongoing operational responsibility is planned
  • anonymous consumer VPN usage is what you are looking for
  • existing firewall or VPN solutions already cover the need cleanly
  • access cannot be documented or clarified organizationally

Our goal is not to introduce NetBird everywhere - but to choose the right access layer for your infrastructure.

Build + Operate

Secure access does not end at the first login

A working tunnel is not yet a secure access concept. Production secure access needs ongoing operations: user and group maintenance, updates, monitoring, policy reviews, documentation, incident response and adjustments for new systems.

We pay attention to:

  • clear responsibilities for users, devices, groups and routes
  • regular reviews of policies and access
  • monitoring of control plane, relays, routes and critical connections
  • updates, security patches and CVE assessment
  • documented emergency access and break-glass processes
  • traceable changes to network and access
  • integration into existing infrastructure, cloud and operating processes
Managed Service

Frequently asked questions about secure access & VPN

Answers to the most important questions about architecture, NetBird, operations and fit.

Classic VPNs route all traffic through central gateways - with bottlenecks, single points of failure and blanket access rights. A mesh VPN like NetBird establishes direct WireGuard connections between devices and controls access centrally via policies, groups and roles. That improves performance, resilience and control.

No. We assess what stays and what gets replaced. We often combine NetBird with existing firewalls, routing and SSO - and phase out legacy access step by step without interrupting operations.

Always in parallel, never as a cut-off date switch. First we take stock: which access paths exist, which users, which machines, what is internet-exposed? Then we build the control plane, connect your identity provider for SSO and MFA (Authentik, Keycloak or an existing one) and set up the first peers and access policies. Sites and systems without a client are added via routing peers. User groups move one after another, the old access stays as a way back until the end - only then is the exposed listener switched off.

Usually one of three reasons. First compliance: the German NIS2 implementation act has been in force since 6 December 2025 and explicitly names multi-factor authentication as a risk management measure - OpenVPN and plain WireGuard bring neither user management nor MFA. Second vendor decisions: Fortinet removed SSL VPN tunnel mode from FortiOS 7.6.3 on all FortiGate models, and existing configurations are not carried over on upgrade. Third the threat landscape: internet-exposed VPN appliances are a preferred initial access vector for ransomware.

Yes. The entire control plane - management, signal and relay - can run on your own or European infrastructure. That keeps data, access and availability under your control. We handle setup, SSO integration and operations.

Via network routes: a routing peer in the respective network makes servers, plants or entire subnets reachable without installing a client on every system. This is particularly suitable for legacy systems, HMIs and site-to-site connectivity.

With granular policies: external users get access to exactly the systems they need - by user, group, device or service, traceable and revocable at any time. The rest of the network stays closed.

Yes. With Managed Secure Access we take over updates, security patches, monitoring, alerting, policy maintenance, client rollouts and incident response - with clear responsibilities and an SLA.

That depends on devices, sites, operating model and SLA. After a short architecture call you receive a concrete offer with a fixed monthly price - no per-user fees.

Planning secure access?

Whether it's an existing VPN, new site-to-site connectivity or NetBird operations: in an architecture call we clarify which access model fits your infrastructure - and what an operable setup can look like.

Timo and Robin from WZ-IT set up a RocketChat server for us - and I couldn't be more satisfied! From the initial consultation to the final implementation, everything was absolutely professional, efficient, and to my complete satisfaction. I particularly appreciate the clear communication, transparent pricing, and the comprehensive expertise that both bring to the table. Even after the setup, they take care of the maintenance, which frees up my time enormously and allows me to focus on other important areas of my business - with the good feeling that our IT is in the best hands. I can recommend WZ-IT without reservation and look forward to continuing our collaboration! (translated)
