About us
Cyber security works best when capability, expertise, and genuine partnership come together.
We've built a company around unconventional thinking, hard work, and a commitment to meaningful, long-term relationships. When you work with us, you're not just engaging a security provider; you're gaining a partner. A real one. We operate in close collaboration with your team, fostering transparency, trust, and a shared ownership of outcomes.
(We answer our own phones. It's old-fashioned. It works.)
Our Mission.
Our mission is to empower organisations with resilient, long-term protection.
We align our strategies with your business requirements, enhance your internal capabilities, and stay ahead of the evolving threat landscape through continuous improvement of our technologies, methodologies, and personnel. Our goal is to enhance your cyber resilience, both today and in the long term.

Our Story.
“Tarian,” the Welsh word for shield, reflects both our purpose and Jon’s heritage.
But the origin goes back much further, to a young kid with his first x286 DOS machine, no manual, no instructions, just curiosity and persistence. That practical, self-driven approach became the foundation of Jon's career.
Rather than learning security from textbooks, Jon built his expertise through real incidents, real pressure, and real problem-solving across two decades in IT and cyber security. By 2022, after years working alongside executives, technical teams, and frontline responders, Jon saw a gap.
Organisations needed more than monitoring, they needed experienced operators who could work inside their environments – not just report on them. So he founded Tarian Cyber.
What started as a small, specialised consultancy quickly grew. Organisations asked for more, deeper capability, broader support, and a dependable partner who understood the realities of defending complex environments. Tarian evolved to meet that demand, becoming a full-service, Microsoft-aligned security provider supporting organisations across Australia.
Today, we operate as a remote-first team built on trust, transparency, and accountability, bringing together senior talent from across the country. We're trusted by leading Australian organisations across multiple industries, a team shaped by experience, grounded in capability, and united by a commitment to long-term resilience.
Our Values
Not buzzwords – values we live by.
They define how we work together and how we work with clients. These aren't posters on a wall — they're embedded in every action, conversation and engagement.
Trustworthy
We build partnerships grounded in transparency, honesty and long-term thinking.
Capable
Deep expertise, proven methods, and the technical skill to solve complex problems.
Dependable
We do what we say we'll do, every time.
Our Leadership Team
Tarian Cyber is led by business partners Jon, Jack and Zach, who bring decades of combined experience across cyber operations, engineering, intelligence, incident response, and leadership.
Our strength is in the collective "we." The Tarian team is comprised entirely of highly skilled specialists — engineers, analysts, threat researchers, and consultants — all aligned with one purpose: to build cyber resilience and deliver outcomes that our clients can depend on.
(And yes – if your name starts with 'J', you'll fit right in)
Our Difference.
We don't just monitor – we deliver measurable outcomes. Our senior analysts work directly in your Microsoft environment around the clock, refining detections, strengthening configurations, and reducing response times in real time.
The result?
Faster incident resolution, better security ROI, and a team that feels less like a vendor and more like an extension of yours.
(We're in your environment enough that your team forgets we're external. That's the goal.)
