Small businesses are often targeted because attackers expect weak defences. The good news: a few basics block most threats.
1. A properly configured firewall
Your router's default settings aren't enough. A business firewall filters malicious traffic and separates guest and staff networks.
2. Multi-factor authentication
Turn on MFA for email, banking and cloud apps. It blocks most password-based attacks.
3. Regular, tested backups
Keep at least one backup offline or in the cloud, and test restoring it.
4. Staff awareness
Train staff to spot phishing emails, fake invoices and suspicious payment requests.
5. Updates and antivirus
Keep systems patched and protected. Our managed IT service can handle this for you.
