Services

Eight areas, one point of contact

IT, hosting and websites for businesses of any size and private clients in Nordhessen, from one fixed point of contact. I set up, support and document, so you stay independent.

From practice

What I run myself, every day

Everything I set up for clients runs on my own systems first. This environment is my testbed.

15+ VMs
A Proxmox cluster with over 15 virtual machines and containers in a German data center and at a second site, connected via encrypted VPN, with no open admin ports.
24/7 Alerts
A central SIEM, intrusion detection and automatic blocking; alerts via push notification and email.
WORM Backup
Nightly backups, an off-site copy with write protection, and documented restore tests.
TLS 1.3
My own hosting platform for business websites behind Cloudflare, with automatic certificates and uptime monitoring.
DMARC
Email security for several company domains: SPF, DKIM, DMARC with reporting, MTA-STS, DNSSEC.
Remote
Windows workstations as virtual machines with secured remote access and two-factor authentication.
Local AI
An AI assistant with a local language model for inbox triage, alert sorting and research. The data stays in-house.
Nordhessen
Websites and IT support for businesses in the region, including a language school and a construction company with NAS, cloud storage and remote support.
