Zero trust architecture
One stolen login should not open your whole business.
Most networks trust anyone who gets past the front door, so when an attacker gets one password they can often reach everything. We change that. Every sign-in is checked, every person reaches only what their job needs, and unknown devices stay out.

What changes
What is different once it is in place.
Pick one to see how it works day to day.
Every sign-in is checked
Being in the office or on the VPN no longer counts as proof. Each login is checked for who it is, what device it is on and whether anything looks off.
- Conditional Access in Entra ID
People reach only what their job needs
The receptionist cannot open the finance share. A stolen account can only reach a small part of the business.
- Access reviewed on a schedule
Unknown devices are kept out
Company data opens only on laptops and phones we manage that are encrypted and up to date.
- Device compliance through Intune
Remote access without the old VPN
Staff reach the apps they need from home or on the road, and nothing else on your network is exposed to the internet.
- Zero trust network access on Ultimate
Odd behaviour gets noticed
A login from overseas at 3am or a sudden mass download raises an alert, and an analyst looks at it.
- 24/7 managed detection on every plan
Answers get easier to prove
Zero trust controls line up with what SMB1001, the Essential Eight, insurers and tender questionnaires ask about.
- Evidence kept current

Why now
The front door is not the only way in.
Attackers now get in through unpatched systems more often than through stolen passwords, and almost half of breaches involve a supplier. Zero trust assumes one of them will work, and limits how far it gets.

Not sure how far off you are?
Run our free security gaps tracker first. Thirteen questions covering the controls SMB1001 and the Essential Eight ask about. Your answers stay in your browser, and you finish knowing which gaps to close first.
The sign-in half of zero trust, Conditional Access, multi-factor and least privilege, is covered in more detail on our identity and access page. The watching half is managed detection and response: alerts from odd sign-in behaviour reach an engineer who acts.
How it works
Done in stages, without stopping work.
- Step 1Map it
Who uses what, from which devices, and where your important data sits.
- Step 2Lock sign-in
Strong sign-in checks and device rules first, because that is where most attacks start.
- Step 3Cut access back
Each person and each account reaches only what it needs.
- Step 4Keep it tight
Sign-ins and access reviewed regularly as people and systems change.
Cybersecurity
Eight layers. One team running them.
Every layer is run by the same Brisbane engineers who look after your IT, so an alert, a leaked password and a suspicious email all land with people who already know your business.

Questions
What people ask before they call.
What is zero trust?
A way of setting up security where nothing is trusted just because it is inside your network. Every sign-in and every request is checked for who it is, what device it comes from and whether it makes sense, before access is given.
Is it a product we have to buy?
No. It is a set of rules built mostly from tools you already have in Microsoft 365, like Microsoft Entra ID and Intune. We set them up in stages so work is not disrupted.
Is it only for big companies?
No. Smaller businesses often find it easier, because they have fewer systems. Most of our clients have between 5 and 150 staff.
How does it relate to the Essential Eight?
Several Essential Eight strategies, such as multi-factor authentication and restricting admin rights, are zero trust controls, and they carry into ASD's new Essentials series. Doing this work moves you up the maturity levels.
Do we still need a VPN?
Usually not. Zero trust network access lets staff reach the specific apps they need from anywhere, without putting your whole network on the internet. It is part of our Ultimate plan, and we quote it on other plans.
How long does it take?
It is done in stages. Sign-in and device checks usually come first, then access clean-up. We agree the order and timing with you after mapping your setup.
