📍 Serving Perth and surrounding areas — Perth-based cyber security and managed IT specialist.
Perth runs on a particular kind of firm. Along St Georges Terrace and through the CBD you have accounting practices, law firms, financial advisers and engineering consultancies feeding the resources sector. Out through Osborne Park, Malaga, Welshpool and Canning Vale you have the trades, fabrication, logistics and construction outfits that keep the projects moving. Most of these businesses run lean — 5 to 50 staff, an owner or director making every call, and no full-time IT person on the payroll. The work is real, the margins matter, and nobody has an afternoon spare to chase a problem nobody warned them about.
That shape changes what good IT support means here. A 20-person Perth firm does not need a server room or a person sitting in the corner waiting for something to break. It needs the things it already pays Microsoft for — Microsoft 365, Teams, SharePoint, Outlook — set up properly, locked down, and watched. The gap we see again and again is not missing software. It is software that was switched on, never hardened, and quietly left wide open while the business grew around it.
The threat that lands hardest in Perth is not exotic. It is the fake invoice. A construction firm in Welshpool is mid-project, money is moving between the builder, subbies and suppliers, and an email arrives that looks exactly like the supplier's — same name, same signature — asking that the next payment go to "updated" bank details. By the time anyone calls to check, the transfer has cleared. The same script hits accounting practices during tax season and law firms sitting on trust account money. The attacker is not breaking in. They are walking through an inbox that was never set up to prove who an email really came from.
Underneath that sits the credential problem. Staff reuse passwords, those passwords surface in known breach databases, and a single working login into Microsoft 365 gives an attacker the keys — mailboxes, files, the lot. For a medical or allied-health practice that means patient records under the Privacy Act; for an NDIS provider it means participant data; for an engineering consultancy it means a contract and project history that took years to build. The other quiet killer is backup. Plenty of Perth firms assume their data is safe because "it's in the cloud," then discover after an account is compromised that there was never anything they could actually restore from.
We are one Perth team, and we support Perth businesses remotely — no offshore, no interstate handoff. Because nearly every firm here already lives inside Microsoft 365, we work with what you own rather than bolting on more. The fake-invoice problem starts with email: we put SPF, DKIM and DMARC in place so your domain can no longer be spoofed, and add Defender for Office 365 to catch the phishing and impersonation attempts before they reach a payroll or accounts clerk.
For the credential and access risk we use Entra ID and Conditional Access — multi-factor authentication on every account, with sign-ins from outside Australia or off unmanaged devices challenged or blocked, so a breached password on its own gets nobody in. Across the laptops and phones your staff use on site and from home, Microsoft Defender and Intune give us protection and control on every device, so a lost phone in a Perth cab or an unpatched laptop is not a way in. Purview brings order to where sensitive data sits across SharePoint and email — which matters before any practice turns on Microsoft Copilot. And Microsoft 365 Backup means that if the worst happens, your mail and files can actually be restored, not just hoped for.
Most Perth owners do not need a sales pitch. They need to know, plainly, where they stand right now — whether their email can be spoofed, whether staff passwords are already sitting in a breach, whether there is a real backup behind the business. That is exactly what the Free Cyber Risk Snapshot gives you: a 30-minute external look, in plain English, with no obligation and nothing to install. You see what is exposed, you keep the findings, and you decide what to do next. If you run a business between the CBD and the industrial fringe and you have never had an honest answer to those questions, that is the place to start.
