Is the Cyber Wardens course only available to small business owners?

No, the Cyber Wardens course is designed for anyone who owns, runs or works for an Australian small business. This includes sole traders and part-time and casual employees. 

While designed for small businesses, Cyber Wardens is also valuable if you are currently looking for work, studying, or planning to start a business. The aim of the program is to build a cyber-safe community across all small business segments in Australia.
