I support your IT at every stage and level.

Common problems

Start with the symptom

Most engagements begin with a single sentence typed into a search box late at night. If any of these sounds familiar — I know what comes next.

Are my devices secure?
A configuration audit.
The fix
The network slows down at the same time every day
Performance monitoring that pinpoints the real cause, not the symptom.
The fix
Office 365 / Sharepoint / Onedrive and user mailboxes and storage backup
A backup strategy providing full user data backup and restore.
The fix
Unauthorized devices keep getting onto the network
Access control with 802.1X, NPS or ClearPass, plus segmentation.
The fix
A breach surfaced after the fact and the logs say nothing
A SIEM/XDR deployment and event analysis that actually holds up (Wazuh).
The fix
One internet line — and when it fails, everything stops
Multi-ISP SD-WAN with automatic failover to a backup link.
The fix

Don't see yours? Describe it in a few sentences — I'll tell you whether and how it can be solved.

What I do

Four areas, one engineer who owns the outcome

No hand-offs between departments or consultants. From design, through deployment, to day-to-day operation.

Monitoring & visibilityZabbix · Grafana · NOC
See what's happening on your network and servers before your users do. Outages and bottlenecks caught while they're still small.
Security & detectionSIEM · XDR · Wazuh · SOC
Continuous collection and analysis of events. Incidents caught as they happen — not weeks later from the logs.
Networks & firewallsFortiGate · Palo Alto · Extreme · SD-WAN
Design, deployment and operation of networks and security policy. VPN, segmentation, access control, high availability.
IT support & outsourcingServers · Virtualization · Backup
Care for your network, servers, virtualization and backup. I handle the routine tickets and the hard ones alike.

About

Ten years of hands-on production work — not slideware.

Day to day I'm responsible for the network and security of a large production environment: thousands of devices, hundreds of policies, infrastructure with no right to downtime. I bring that same experience to your company.

I'm not tied to any vendor. I choose the solution that fits the problem, not the price list. Many of them are proven open source — no licenses, no subscriptions for years.
