IT Security in Mannheim for Small Infrastructure
I help make small infrastructure safer and easier to reason about: fewer open ports, clear access paths, backups, and documented assumptions.
Reduce risk while keeping operations simple
Not every system needs complex enterprise tooling. Clean firewall rules, MFA, separated networks, VPN, and consistent updates often deliver the biggest gain.
Practical zero-trust access
I use small, understandable control points: Cloudflare Access, Tailscale, WireGuard, SSH keys, restricted admin paths, and monitoring.
Typical Work
- Firewall and VPN concepts for small environments
- SSH hardening, keys, MFA, and access hygiene
- Zero-trust access with Tailscale, WireGuard, or Cloudflare Access
- Backup and recovery checks for self-hosted stacks
