Advanced technology. Sovereign outcomes.

SolStak is an Australian-owned ICT consultancy specialising in architecture, engineering, networks, cyber security, and assessments. What began as a project recovery practice has grown into a sovereign consultancy and delivery team—trusted when programmes are in distress and equally valued for greenfield design, build, and assurance work across Defence, government, and enterprise.

We are a serious engineering outfit: our people work fast, communicate plainly, and have the agility to change direction when the mission demands it—without losing control of scope, security, or quality. We love a good conversation—and we are happy to offer frank, free advice when you want a straight technical view, with no obligation to engage. We enjoy building the next generation of ICT technology: in the missions we deliver, the platforms we engineer, and the people we grow. Many of our leads bring 20+ years from the enterprise sector; all share a bias for delivery over slideware.

As a Defence Industry Security Program (DISP) member, we support employees and sub-contractors in obtaining required security clearances—and work with industry leaders including Defence, DST, and leading consultancies across Australia.
