What is the ACSC (Australian Cyber Security Centre)?

The ACSC — the Australian Cyber Security Centre, part of the Australian Signals Directorate — is the federal government body responsible for cyber security advice in Australia. For a small business it is the most useful and most trustworthy free resource available:

• The authority behind the frameworks — it publishes the Essential Eight, the Small Business Cyber Security Guide, and alerts on active scams and threats.
• Written for Australian conditions — its guidance is genuinely pitched at non-experts, not only government departments.
• Read the guide — read the Small Business Cyber Security Guide once for a plain-language baseline.
• Subscribe to alerts — subscribe to the ACSC’s alert service so you hear about a major threat from the source rather than from a vendor trying to sell you something. You can also report a cybercrime or scam through ReportCyber.

When a security claim cites "the ACSC", it is citing the Australian government’s own cyber authority — start there before you trust a vendor’s framing.
