IT security & digital sovereignty since 1993
We've been building the perfect IT solution for our clients for more than 30 years
Our solutions
Six areas, one principle: your IT belongs to you.
- 01Cloud Exit & Digital SovereigntyBack in control: your secure cloud exitDependence on international hyperscalers is a risk – for data protection, predictability, and your digital sovereignty. We guide you safely out of vendor lock-in: repatriation to a modern on-premise infrastructure, or migration to GDPR-compliant German providers such as IONOS and Hetzner.
- 02Managed IT & IT OperationsYour everyday IT, reliably operatedWorkstations, networks, servers, Microsoft 365, backup, and helpdesk: we run your IT and proactively prevent downtime – with thoughtful monitoring and friendly support. Built on open, vendor-independent technologies wherever it makes sense.
- 03IT Forensics & Incident ResponseSecurity that delivers when it mattersWe harden and monitor your systems – and we're there when something still happens. As forensic analysts we investigate attacks, secure court-admissible evidence, and bring your operations back under control.
- 04Secure Mobile WorkspaceMobile work - secure, and in your own handsProductive work from anywhere, with the same standards as in the office – and your data stays with you.
- 05New Company & Switching IT ProvidersNew company, new location, switching providersNew company, new location or switching providers – we take over and align your IT with independence.
- 06Local & Secure AIArtificial intelligence - tailored and localAI on your own hardware or in German data centers – without trade secrets leaking out.
Our story
Security isn't a trend for us – it's where we come from
We've worked with Linux since 1993 – since the first usable kernel versions. In 2000 we were at the very first CanSecWest in Vancouver, when tools like Snort and nmap were shaping the young security scene and the first intrusion detection systems – Snort versus Dragon – were competing for their place.
That enthusiasm turned into research: at DIMVA 2004 we presented “V-IDS”, our own approach to making attacks from Snort and firewall data visible in three dimensions – and thus comprehensible to people.
Our focus today grew directly out of this line: a deep understanding of systems, open technology and the question of how to really see and understand attacks. That is the digital forensics, incident response and sovereign IT we use to protect you today.

Our foundation: open source since 1993
Transparency builds trust. We've worked with Linux since 1993 - since the first usable kernel versions. Open code can be reviewed, audited, and maintained independently - protecting you from licensing traps and vendor lock-in, and giving you back control.
