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.
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: 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

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.
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.
