10 Essential Cybersecurity Measures for SMEs in Africa

Cyberattacks no longer target only large corporations. In 2024, more than 60% of cyberattacks target SMEs, which are often less well protected and therefore represent easier targets. In Africa, awareness is still insufficient: fewer than 20% of SMEs have a documented IT security policy.

Here are the 10 priority measures every SME should implement immediately.

1. Enforce a strong password policy

This is the foundation of all IT security. Require passwords of at least 12 characters mixing upper and lower case, numbers and special characters. Deploy a business password manager like Bitwarden or 1Password and enable two-factor authentication (2FA) on all your critical accounts.

2. Keep your software up to date

80% of cyberattacks exploit vulnerabilities for which patches exist but haven't been applied. Enable automatic updates on all your operating systems, antivirus and business applications. Define a patch management policy with application timelines based on vulnerability criticality.

3. Back up your data regularly

Apply the 3-2-1 rule: 3 copies of your data, on 2 different media, with 1 off-site (cloud). Test your restores regularly: an untested backup is a non-existent backup. In the event of ransomware, recent backups let you resume operations without paying the ransom.

4. Train your employees

Humans are the weakest link in the security chain. 90% of security incidents start with a phishing email clicked by an employee. Organize regular awareness training, phishing simulation exercises, and build a security culture within your organization.

5. Secure your Wi-Fi network

Your business Wi-Fi network should be separate from your guest Wi-Fi network. Use the WPA3 protocol if possible, or WPA2 at minimum. Change your routers' default passwords and disable unnecessary features like remote administration.

6. Encrypt your sensitive data

Customer, financial and strategic data should be encrypted, both at rest (on your drives) and in transit (during exchanges). Use HTTPS for all your websites, VPN for remote access, and BitLocker or FileVault to encrypt your laptop drives.

7. Control access with least-privilege principles

Each employee should only have access to the data and systems necessary for their job. Revoke access immediately upon departure. Regularly audit access rights and remove inactive accounts. This measure significantly limits damage in case of account compromise.

8. Have an incident response plan

What would you do if you were hit by a cyberattack tomorrow morning? Having a documented, tested plan can be the difference between a few hours of downtime and several days. This plan should identify responsible parties, containment steps, remediation and crisis communication.

9. Monitor your systems continuously

What you can't see can hurt you. Set up basic monitoring of your systems: connection logging, alerts on abnormal behavior, incoming email monitoring. Tools like Wazuh (open source) provide intrusion detection accessible to SMEs.

10. Have your security audited by experts

Every 6 to 12 months, bring in cybersecurity professionals to audit your infrastructure and test your defenses. A penetration test (pentest) will reveal vulnerabilities your internal measures haven't detected.
