Cybersecurity that protects the business, and unlocks what's next.
Compliance, cost, AI and growth are landing on you at once. We start with your business outcome, not the framework, sequence the security work around it, then hand you the keys to run it. No lock-ins.
Essential Eight and the standards that matter become structure the business actually needs.
Licensing and tool consolidation becomes reclaimed budget.
AI rollout becomes a question your business can answer.
Security becomes the thing that funds your next move.
Built to empower, not depend.
Some providers sell you complexity. We build clarity.
Our projects are designed to get your systems running securely, efficiently, and independently. Once everything is in place, we hand over complete documentation, governance, and control, so you can manage it with confidence.
No lock-ins. Just results, relationships, and real impact.
We build, you run it
Everything we deliver is documented, configured and handed over for you to manage.

At Cornerstone Cyber, we blend technical expertise with strategic thinking to make cybersecurity simple, scalable, and effective.
We don't just sell solutions, we help you build the right ones.
Three pillars. One outcome.
We work across Identity, Device and Data: the three places risk lives and value moves, so your business runs in your control, not your supplier’s.
Conditional Access, MFA and least privilege, so the right people reach the right things and no one else does.
Intune, Autopilot and a managed SOE that makes work faster, not harder, on every device.
Know where sensitive data lives, label it automatically, and control where it can go.

What does Cornerstone Cyber actually do?
We design, implement and integrate cyber and IT systems, then hand them to your team to run. We are not a managed service provider; once we build it, you own it.
How are you different from a managed security service?
We do not lock you into an ongoing service contract. We design the system, document it, train your team, and step away. You keep the keys, the credentials, and the choice to bring us back when you want.
What technologies do you work with?
Microsoft 365 (Entra, Intune, Purview, Defender), Netskope (SSE, DLP, AI security), CrowdStrike (endpoint), Cyera (DSPM), Mimecast (email and insider risk), Delinea (PAM), Veeam (backup) and supporting tools across Identity, Device and Data.
Do you help with Essential Eight compliance?
Yes. We assess your current maturity, build a prioritised roadmap across all eight ACSC strategies, and implement the controls needed to reach Maturity Level 1, 2 or 3.
Where do you work?
Across Australia. Cornerstone is an Australian-owned independent cyber and IT systems integrator.
How do engagements usually start?
A short conversation, then a structured health check. We give you a clear picture of where you stand today, what matters most, and a costed plan you can act on.
