SolStak

SolStak is an Australian-owned ICT consultancy serving Defence, government and critical enterprise organisations. Founded in 2018, the company focuses on sovereign technology outcomes, combining architecture, engineering and cybersecurity expertise with practical delivery. Its work spans cloud and platform services, networks, cyber security, IRAP assessments, sovereign AI, systems integration, secure mobility and sovereign software development. SolStak also provides project recovery, independent assurance and support for mission systems, helping stabilise programmes in difficulty as well as design and deliver new capabilities.

The consultancy takes a hands-on approach, working from strategy and architecture through engineering, assurance and production. It emphasises accountable delivery rather than simply supplying staff. Its personnel bring extensive Defence and national security experience, and SolStak supports the security clearances required for sensitive work. The company is a member of the Defence Industry Security Program and holds listings on Defence and government ICT procurement panels. SolStak works with public-sector, health and technology customers, offering direct technical advice and delivery support for organisations seeking secure, sovereign ICT capability.
