Intro

From the rule to the secure connection.

We help small and mid-sized businesses with firewall configuration and maintenance, remote-access VPNs and connections between selected locations. Access is always considered in the context of your existing network structure.

Firewall & VPN is a distinct service: we are vendor-independent and can generally take over existing firewall environments on any platform, provided the specific technical responsibility is clear. Networking & Wi-Fi covers LAN, Wi-Fi and infrastructure; the broader IT security service covers additional protection measures. We do not promise blanket security guarantees, but clearly planned and documented measures.

Our process

How we work

  1. Review the environment

    We map the firewall, connections, VLANs, rules, VPNs, access and existing documentation. Dependencies and open risks become visible.

  2. Plan the access

    We align networks, roles and required connections and create a clear plan for rules, VPN access and site-to-site links.

  3. Implement the changes

    We configure the agreed changes with as little interruption as possible. Larger changes are planned in suitable maintenance windows.

  4. Support the operation

    If wanted, we review rules, observe agreed signals, support updates and keep important changes documented.

FAQ

Frequently asked

Which types of VPN do you support?
We support remote-access VPNs for staff and site-to-site VPNs connecting locations or selected networks. The right option depends on access needs, the existing environment and the desired operating model.
Can you take over an existing firewall?
Yes. We start by reviewing the device, firmware, connections, rules, VPNs, VLANs, access and documentation. We then discuss risks and a predictable takeover path.
What is a site-to-site connection?
A site-to-site connection links selected networks at two locations through an encrypted connection. We plan which systems actually need to be reachable and limit access to that requirement.
How often should firewall rules be reviewed?
Rules should be reviewed when applications, users, locations or networks change. A regular baseline review is useful as well; we agree the cadence based on the pace, size and documentation of your environment.
How does network segmentation relate to firewall security?
VLANs and separated networks create clearer security areas. The firewall can then allow, log or block traffic between those areas deliberately. Segmentation, rules and workflows need to be planned together.
Which firewall platforms can you take over?
We are vendor-independent and can generally take over existing firewall environments on any platform. During the review, we check the configuration, access, documentation and the specific technical responsibility.
Can the firewall be administered remotely?
Yes, where the environment supports a suitable and secured access path. We prefer traceable administrative access with clear permissions and avoid unnecessarily exposed management interfaces.
