The average Australian SMB breach goes undetected for 200 days. By the time you know something is wrong, the damage is done.
Cybercrime targeting Australian small and mid-sized businesses has increased sharply. The challenge is that most business owners don't know they have a cybersecurity problem until it's already a crisis. Here are five warning signs — and what to do about each one.
Sign 1: Multi-factor authentication isn't enforced everywhere
If your staff can log into Microsoft 365, your accounting software, or any business application with just a username and password, you are significantly exposed. Credential-based attacks are the number one entry point for cybercriminals targeting SMBs. MFA blocks over 99% of automated attacks. If it's not on everywhere, this is your highest priority fix today — not next quarter.
Sign 2: Your staff haven't had security training in the last 12 months
Your people are simultaneously your biggest cybersecurity asset and your biggest vulnerability. Phishing emails, fake invoice scams and social engineering attacks target human behaviour, not technical vulnerabilities. Annual checkbox training doesn't change behaviour. Regular, practical security awareness training — including simulated phishing — does.
Sign 3: You're running software or systems that are no longer supported
End-of-life software doesn't receive security patches. Every day it runs, it accumulates unpatched vulnerabilities that cybercriminals actively exploit. Windows 10 reached end of life in October 2025. If you're running it — or anything older — your environment has a significant unpatched exposure.
Sign 4: You've never actually tested your backups
Most businesses think they have backups. Fewer have tested whether those backups actually work. Ransomware gangs specifically target backup systems before deploying their payload. If your backups haven't been tested in the past 12 months — or are connected to your main network — they may not save you when you need them.
Sign 5: Nobody is actively monitoring what's happening in your environment
If your approach to IT security is "we'll deal with it if something goes wrong," you've already accepted a significant risk. Modern cyber threats dwell in environments for an average of 200 days before detection. Proactive monitoring — through endpoint detection and response (EDR) and security event management — catches threats before they become catastrophes.
