Network design & administration
Campus, office and data-centre networks designed for resilience and easy operation, then documented so your team understands them. Routing, switching, VPNs and monitoring that tells you about problems before your users do.

- Site-to-site and remote-access VPNs
- Network monitoring (Zabbix, PRTG)
Firewall configuration & review
New firewall deployments, migrations and rule-base clean-ups. Segmentation that limits how far an incident can spread, with every rule justified and recorded.

Bespoke development
Occasionally, the right answer is a small piece of software: an automation script, an internal tool or an integration between systems. Where that fits, it is built with the same care for security and documentation.

About
One engineer, accountable end to end
Proton IT Services is the consultancy of Nicholas Xerri, an infrastructure and security engineer based in Malta.
Nicholas started out in network operations in 2006 and has since worked across government, iGaming and banking, as a network engineer, solutions architect, principal Linux engineer and senior production engineer. Along the way he has been responsible for networks, firewalls and Linux estates where downtime and security failures were not an option.
His approach is simple: understand the problem first, build things that are secure by default, automate what can be automated and document everything so you are never dependent on one person, including him.
Works in English, Maltese and Italian, with conversational French.
