Most attacks on small businesses are not sophisticated. They rely on a reused password, a convincing email or a computer that missed its updates. That is good news, because the defences are well understood and affordable.
1. Multi-factor authentication everywhere
If you do one thing this year, make it this. Multi-factor authentication (MFA) means a stolen password alone is not enough to get into email, remote access or your accounting system. Turn it on for every user, and especially for anyone with admin rights.
2. Automatic patching
Updates close the holes that attackers use. Windows, Microsoft 365, web browsers, PDF readers and firewall firmware all need regular patching. A managed service applies updates on a schedule and tells you when something fails, so nothing quietly falls behind.
3. Modern endpoint protection
Traditional antivirus looks for known bad files. Endpoint detection and response (EDR) watches for suspicious behaviour, such as a program suddenly encrypting hundreds of files, and can stop it mid-attack.
4. Backups that ransomware cannot touch
Ransomware goes after your backups first. Keep at least one copy offsite and immutable, meaning it cannot be changed or deleted even with admin credentials. Then test a restore regularly. We cover this in more detail in our article on backups.
5. Staff who know what to look for
Most incidents start with an email. Short, regular security awareness training and the occasional simulated phishing test make a measurable difference, and they help staff feel confident about reporting a mistake quickly.
