Free cyber security check now open to every Australian business, not just charities
Suburban Secure’s free, public-signal cyber security check has so far been built around Australian charities and not-for-profits, searchable by ABN or ACNC listing. It’s now open to any Australian business too, with its own dedicated free business cyber security check at suburbansecure.au/free-business-cyber-check — enter your business name and domain directly (ABN optional) and get the same plain-English result, no charity registration required.
The question behind it is simple: if you paid someone once to set up your website and email — a few years ago, maybe by an IT contractor who has since moved on, or a “tech-savvy” staff member who left — when did you last check it’s still configured safely? Security settings do not fail loudly. SPF and DMARC records quietly stop matching how mail actually gets sent. Certificates lapse. Nobody notices until mail starts landing in spam, or worse, until a scammer sends an invoice that looks like it came from your own domain.
The check itself is unchanged from the charity version: only public, passive information — no login, no credentials, nothing beyond what a normal browser or DNS lookup would already see. It looks at SPF, DMARC and DKIM visibility, DNS name servers and CAA records, HTTPS availability and certificate health, reverse DNS, and public spam blocklist status.
It’s deliberately scoped as a lightweight public-information check, not a penetration test or vulnerability assessment — and we say so on the page itself, along with what it genuinely can’t see (administrator access, backup health, MFA coverage, vendor handover). A free check that’s upfront about its own limits is more useful than one that quietly implies it checked everything.
Every submission is flagged to our team the moment it runs, not on some future batch import, so if the report turns up something worth a conversation, a real follow-up can happen within hours rather than weeks — from a real, Townsville-based business with a named person on the other end, not an anonymous SaaS tool.
If you run a small business, a trades outfit, a professional practice, a retail or hospitality venue, or anything in between, it’s worth two minutes to see what your domain is quietly telling the world. The charity-specific check stays exactly as it was for ABN/ACNC search — this just adds a second front door into the same tool.
