After You Get Your Result
📋 Real Example — Essential Eight Checklist
A Thomastown import business scored 28% on the Essential Eight. We resolved the top four gaps in a half-day visit — MFA on email, patching schedule, admin restriction, and backup configuration. Cost: $380. Ransomware recovery cost: $39,000 average.
What's Actually Causing This?
Understanding the cause helps you make better decisions — and helps us fix it faster.
Patch Applications
Unpatched software is the leading entry point for malware and ransomware. Australian businesses suffer most attacks through known, unpatched vulnerabilities.
Multi-Factor Authentication
MFA blocks 99.9% of automated account attacks. Without it, a leaked password gives attackers full account access within seconds.
Restrict Admin Privileges
Most malware requires admin rights to install. Limiting who has admin access dramatically reduces the blast radius of any successful attack.
Application Control
Only allowing approved apps to run prevents unknown executables — the mechanism most ransomware uses — from ever launching.

Key Questions
Is It Worth Fixing? Can It Get Worse? Hardware or Software?
Which controls matter most: MFA and patch applications block the majority of cyberattacks. Application control and admin privilege restriction reduce the blast radius of any successful attack. Start with these four.
What happens without Essential Eight: The Australian Cyber Security Centre reports that implementing the Essential Eight would prevent the vast majority of intrusions. Without it, small businesses are increasingly targeted — and disproportionately victimised.
How long does implementation take? MFA on email accounts: 15 minutes. Patching applications: ongoing but automatic. Restricting admin rights: 30–60 minutes across a small team. Essential Eight baseline for a 5-person business: one half-day professional visit.
🚨 Urgency note: Ransomware attacks on Australian small businesses increased 47% in 2024. An Essential Eight baseline prevents the majority of these incidents.

Professional Help
Do You Need a Professional Repair?
✅ You can DIY if:
You can implement yourself: enable Windows Update auto-install, set up MFA on email accounts, disable unused admin accounts, and schedule weekly Defender scans. These four steps alone raise most home and small business security postures significantly.
🔧 You need professional repair if:
You need professional help if: you're running a business with multiple devices, you handle customer data or payments, you need application control or SIEM logging, or your score is below 50% on this checklist.
⚠️ What happens if you ignore this: Small businesses without Essential Eight controls are 3x more likely to suffer a ransomware incident. The average cost of a ransomware recovery for an Australian small business is $39,000 — compared to $380–$600 for a professional Essential Eight implementation visit.
