Services

The work that keeps a business running.

Network design & build

Cisco, Aruba, Fortinet and Palo Alto deployments — from a single office switch to multi-site VPN and segmented guest networks.

Systems administration

Linux and Windows server management, patching, backup and recovery that has actually been tested rather than assumed.

Proxmox & virtualization

VE clusters, Backup Server and Mail Gateway — plus a migration path off VMware licensing. Real redundancy instead of a single server everyone prays to. Proxmox details →

Mail & collaboration

Self-hosted mail that actually delivers — SPF, DKIM, DMARC and reputation configured correctly, not left at defaults.

Automation

Ansible-driven configuration so the network is reproducible, recoverable and documented — not held together by memory.

Monitoring & security

Zabbix and Grafana observability, alerting that means something, and CrowdStrike-backed endpoint protection.

How we work

No mystery, no lock-in, no surprises.

Assess

We look at what exists — topology, hardware, licensing, backups — and tell you plainly what is fragile and what is fine.

Build

Changes happen deliberately, documented as they go, with a rollback path before anything goes live.

Hand over

You get the diagrams, the credentials and the runbooks. If you ever leave, you leave with everything.

Have something that needs fixing, or building?

Most engagements start with a conversation about what is failing and what it would take to stop failing.
