A free cyber security check for businesses and charities

Our sister business, Suburban Secure, has released a free cyber security check for Australian businesses, charities and not-for-profits. It is instant, written in plain English and does not require an account.

The check begins with a question every organisation should be able to answer: can somebody send an email that looks like it came from us? It examines public signals around SPF, DMARC and DKIM email authentication, DNS and domain control, website HTTPS and certificate health, reverse DNS, and public spam blocklists.

Most business technology is not deliberately neglected. A website and mailbox are set up, they work, and everyone gets on with serving customers. Years later the original provider may have changed, a staff member may have moved on, or recommended security settings may have advanced. Configuration can drift quietly even when nobody has done a bad job.

That is why we believe this is a useful service for Townsville businesses. A computer repair may solve the immediate device problem, but email, domain and website settings are also part of the technology foundations a business relies on. A spoofed message that appears to come from the business can damage trust before anyone realises a public protection was missing.

Charities and not-for-profits can search by ABN or ACNC-listed organisation name. Businesses can enter their name and domain directly, with an ABN optional. Both paths use the same underlying check and show the result immediately. An optional emailed report link can be shared with an owner, manager, board, treasurer or existing IT provider.

The result is an honest starting point, not a penetration test. A public check cannot see administrator access, multi-factor authentication coverage, backup health or whether a former supplier completed a proper handover. Those questions need a broader review. What the free tool can do is make visible signals easier to understand and point to sensible next steps.

Suburban Secure shares our practical, local approach. It is Townsville-based, there is a named person behind it, and there is no pressure or hidden obligation attached to running the check. If the result uncovers something that needs attention, the team can help; if it simply helps you ask a better question, it has still done useful work.

• Run the free cyber security check
• Start the business check
• Start the charity and not-for-profit check

The check uses public records and public DNS, email and website signals only. It is not a penetration test or vulnerability assessment.
