Critical Warning
Cyberattacks on Australian businesses increased 30% in 2025. Ransomware attacks cost businesses an average of $250,000 in downtime and recovery. Don't be the next victim - implement these essential security measures today.
7 Essential Security Layers
1. Business Firewall (Not a Home Router!)
A proper business firewall provides:
- Application-level filtering (block specific apps/sites)
- Intrusion prevention system (IPS)
- VPN for secure remote worker access
- Bandwidth management and QoS
- Content filtering
- Detailed logging and reporting
Recommended: Fortinet FortiGate, Sophos XG, WatchGuard
2. Multi-Factor Authentication (MFA)
MFA blocks 99.9% of automated attacks
Enable MFA on:
- Email systems (Microsoft 365, Google Workspace)
- Cloud storage (OneDrive, SharePoint, Dropbox)
- Banking and financial systems
- Remote access (VPN, RDP, SSH)
- Admin accounts (everything!)
3. Regular Backups (3-2-1 Rule)
3 copies of data
2 different media types
1 copy offsite
Critical: Test restores quarterly. A backup you haven't tested is not a backup!
