Server Hardening, Backup & Monitoring

Servers secured, reliably backed up and fully monitored — an operation you can count on.

  • Linux
  • Windows Server
  • Grafana/Zabbix
  • Veeam & Borg
  • Ansible

Status & progress

Completed Duration: ~5 weeks

Completed

  • Servers hardened following CIS recommendations
  • 3-2-1 backup incl. regular restore tests
  • Central monitoring & alerting
  • Documented patch & update routine

Starting point

The servers ran “somehow”: no consistent backup concept, no central monitoring, updates by gut feeling. An outage would have been noticed late — and recovery had never been rehearsed.

Solution

  • Hardening of Linux and Windows servers following recognized guidance (CIS).
  • 3-2-1 backups with automated, regular restore tests.
  • Central monitoring with meaningful alerts instead of noise.
  • Patch routine documented, so updates are predictable rather than risky.

Result

An operation that is monitored, backed up and traceable — issues surface early, and recovery is proven rather than hoped for.

Sounds like something you need too?
