Cybercrime isn’t slowing down — and unfortunately, small and medium businesses are increasingly on the front lines. In South Africa, the cost of a single cyberattack can cripple operations, damage your reputation, and even lead to legal trouble.
Here are the top threats your business should be watching for in 2025 — and what you can do to stay ahead of them.
1. Phishing and Business Email Compromise (BEC)
Phishing remains the number one way cybercriminals access company systems. It’s no longer just dodgy links in spam emails — scammers are getting smart, impersonating suppliers, clients, or even your own staff.
What to do:
- Train your team to spot suspicious emails.
- Use email filtering and threat detection tools.
2. Ransomware
Ransomware locks your data until you pay a fee — and SMEs are often more likely to pay because they lack backup or recovery plans.
What to do:
- Ensure you have reliable, tested backups in place.
- Keep systems and antivirus software up to date.
3. Insider Threats
These aren’t always malicious — they can also come from well-meaning employees who click the wrong link or use weak passwords.
What to do:
- Implement access controls and permission settings.
- Set up basic cybersecurity training for staff.
4. Poor Patch Management
Many businesses forget to update their software regularly. Unpatched systems are easy targets — especially older operating systems and outdated plugins.
What to do:
- Set up automatic updates wherever possible.
- Outsource patching and maintenance to an IT partner.

5. Weak Endpoint Security
With hybrid work now the norm, staff often access company data from personal or mobile devices. Without proper security, every device becomes a potential entry point.
What to do:
- Install and monitor antivirus and anti-malware tools on all endpoints.
- Use endpoint protection and device management solutions.
