About Nick O'Sullivan

Practical IT leadership for organisations.

I started Suburban Secure because churches and community organisations often inherit technology that technically works, but is hard to explain, hard to secure and hard for the next volunteer or leader to manage.

I bring more than 15 years of hands-on IT experience across small business support, school environments, Queensland Government systems, church infrastructure and charity governance. My focus is not selling an ongoing managed service arrangement. It is 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.
  • Security reviews and vulnerability analysis informed by practical frameworks such as the Essential Eight.
  • Church experience across Office 365, SharePoint, Azure, IP PBX, network equipment, servers, Docker and databases.
