Technology experience with a practical leadership lens.

Over 17 years making technology make sense for the people who lead organisations.

I'm Nicholas O'Sullivan, usually Nick — a Townsville-based IT and cyber security professional. I started Suburban Secure because too many businesses, churches and community organisations inherit technology that works today but is hard to explain, hard to secure and hard for whoever takes over next.

I bring more than 17 years of hands-on IT experience, from business network audits through to hands-on support for small businesses, churches and residential clients, plus statewide systems work for the Queensland Government. My focus isn't selling an ongoing managed service arrangement — it's helping leaders understand the risk, choose a sensible architecture, and implement systems that are documented, secure and maintainable.

• Experience with Microsoft 365, Google Workspace, Windows, Linux, virtualisation, cloud and containerised systems.
• Network design, deployment and maintenance across real operational environments, from enterprise-scale sites to small business premises.
• Security reviews informed by relevant ASD guidance, including Essential Eight and the transition to ASD Essentials.
• Church experience across Office 365, SharePoint, Azure, IP PBX, network equipment, servers, Docker and databases.
• ACSC Partnership Program member (Business Partner), staying current with Australian Cyber Security Centre guidance.
• Australian Computer Society Certified Technologist (MACS CT).

I have also served in church and community governance, including with Northreach. My broader professional profile and writing are available at nickosullivan.id.au.
