/// ABOUT · PERTH HQ
Aus Cyber Security started when a Perth IR consultant got tired of flying east for every SMB breach. We built a local team, flat pricing, and plain-language reporting for Western Australian small business.
Founded in Perth after a regional freight ransomware call-out
Western Australia runs on small business — trades, logistics, professional services, regional suppliers. They cannot afford a Sydney SOC retainer or a 200-page framework deck.
We founded Aus Cyber Security to give WA SMBs the same detection and response capability that enterprise gets — priced for teams of 10 to 100, explained in language a board can act on, and staffed by people who answer the phone in Perth time.
Endpoints monitored
500+
Across Perth metro, Peel, South West, and Mid West
Response SLA
<4 hrs
Perth-based incident response, not a ticket queue
Team size
18
Analysts, IR specialists, and client success — all WA-based
Perth HQ, on-site across metro and regional WA. No offshore handoff when you are breached.
Risk reports your leadership can prioritise. No acronym soup, no fear-selling.
Controls we deploy and monitor — not PDF recommendations that sit in a drawer.
Incident response SLA under four hours. Because payroll and freight do not wait.

/// OPERATING PRINCIPLE
We do not sell fear. We sell time back — time your business is not offline, not explaining a breach to a client, not rebuilding from scratch.
Book a 30-minute intro call. We will walk through your stack, your suppliers, and your top three risks — no pitch deck.
