Senior Defensive Security Engineer
Cybertify
Posted 13 days ago
Say hello to Cybertify — the new force in cybersecurity consulting.
We’re not here to blend in. We’re here to raise the bar. Cybertify was founded to bring precision, execution, and operational discipline to cybersecurity in a market that’s lost its edge.
Led by a seasoned lawyer with a track record of building high-performance consulting teams, we are assembling a specialist cyber squad to take on compliance, GRC, offensive & defensive security, and VIP (Private Client) cyber across Australia’s most regulated sectors.
If your current firm has been acquired, diluted, or lost its identity — now is the time to move. Cybertify is independent, focused, and unapologetically ambitious. We don’t have a website (yet), but when it launches, it will speak for itself.
Join us now, before the launch. Help us build it right. Be part of the future of cybersecurity consulting.
Cybertify is Australia’s trusted compliance-first cybersecurity consulting firm. We support organisations in the most highly regulated sectors, including legal, financial services and fintech, healthcare, education, government, critical infrastructure, SaaS, and private clients. Our brand is built on precision, execution, and operational discipline.
