When SentryLink co-founder Maya Chen started her business from a shared workspace on Abbott Street in 2023, she noticed a troubling pattern: Cairns-based small and medium enterprises were spending thousands on cybersecurity tools they didn't understand, while remaining dangerously exposed to the threats that actually mattered.
Three years later, her company is monitoring digital threats for over 40,000 businesses across Australia, with a particular foothold in regional Queensland. What began as a side project has evolved into one of Cairns' most significant tech exports—and a potential game-changer for how businesses think about privacy and security.
SentryLink's innovation is deceptively simple: rather than selling another bloated security suite packed with features most users ignore, the platform uses artificial intelligence to identify and neutralise only the threats relevant to each business. A dental clinic in Port Douglas needs different protection than a logistics firm near Smithfield. SentryLink's algorithm recognises this.
"We realised most small business owners can't afford dedicated IT security teams," Chen explained during a recent presentation at the Cairns Innovation Hub. "They're paying $150 to $400 monthly for tools that don't fit their actual risk profile. We've cut that to under $60, and we actually stop the things that matter."
The numbers support the claim. In independent testing by Brisbane-based CyberAudit Labs, SentryLink detected 94% of common threats against small businesses—outperforming three major competitors that averaged 71%. More importantly, clients report a 67% reduction in false-alarm notifications, meaning employees stop ignoring security warnings.
Cairns' booming tourism and hospitality sector has been an early adopter. Hotels along the Esplanade, reef-tour operators based in the city centre, and resorts around Trinity Beach are now SentryLink clients. The platform's ability to comply with international data-residency requirements—storing Australian client data in Australian servers—has particularly resonated with businesses handling payment information or guest details.
The company now employs 23 people across offices in the Cairns CBD and a development hub in Edge Hill, with plans to expand into Southeast Asian markets by Q4 2026. Earlier this month, SentryLink secured $8.2 million in Series A funding, half from local investors and half from international venture capital.
For Cairns' tech community, SentryLink represents a rare achievement: a locally-born company solving a genuine problem at scale, without requiring relocation to Sydney or Melbourne. It's a reminder that serious innovation can happen anywhere—especially when it starts with listening to what your neighbours actually need.
