Why Nigerian businesses are getting hit harder than ever
Nigerian organisations faced an average of 6,101 attacks per week in Q3 2025. A single healthcare breach exposed 130,000 patient records. Phishing is the root cause of roughly 90% of breaches. Finance-related phishing targeting banks and payment platforms grew 46% in H1 2025. Smaller businesses hold exactly the data attackers want and lack the security investment to protect it. For sector-specific analysis, see top security vulnerabilities facing Nigerian companies.
1. Access control and MFA
Multi-factor authentication is the single highest-return security action your business can take right now. Google Authenticator, Microsoft Authenticator, and Duo Security's free tier are all available at no cost. Apply MFA to business email, accounting software, cloud storage, payroll, and every banking portal. See our authentication security service.
Create role-based access levels. Audit permissions monthly. Disable accounts immediately when staff leave. Use a password manager like Bitwarden (free tier available). For fintech-specific access control, see our 10-point security checklist.
2. Endpoint and email protection
Every device on your network is a potential entry point. Bitdefender, Malwarebytes for Business, and Kaspersky Small Office Security are cloud-managed and deployable without an on-site IT team. Since phishing drives 90% of breaches, configure email filtering with SpamTitan, Proofpoint Essentials, or the built-in filters in Microsoft 365 and Google Workspace.
Configure DMARC, SPF, and DKIM on your domain. Without them, attackers can spoof your domain to phish your own customers. Configuration takes ~30 minutes in your DNS settings.
3. Staff training
GoPhish is a free, open-source tool for simulated phishing. Run simulations monthly. Follow up with targeted training. Cover four specific behaviours: recognising phishing patterns, reporting suspicious activity, using approved file-sharing tools, and verifying before transferring funds. Write a one-page acceptable-use policy.

Follow the 3-2-1 rule: three copies, two media types, one offsite. Combine a local external hard drive with cloud backup (Google Drive Business, OneDrive, or Backblaze). Automate daily cloud backups and weekly full backups to the external drive. Test restores monthly.
5. NDPA 2023 compliance
The Nigeria Data Protection Act applies now. Key obligations: appoint a DPO, conduct annual privacy audits through a licensed DPCO, register with the NDPC at scale, honour data subject rights, and notify the NDPC within 72 hours of a breach. See our Nigeria data protection guide and NDPR/NDPA compliance guide.
6. Incident response
When a breach is suspected: isolate affected systems, preserve all logs and evidence, change compromised passwords, identify the entry point. Do not wipe devices before capturing forensic evidence. You have 72 hours to notify the NDPC. See our after a breach guide and the NDPA breach notification process.
Your practical security checklist
Enable MFA today (free, ~30 minutes). Deploy endpoint and email protection this week. Run your first phishing simulation this month. Set up 3-2-1 backup and test a restore. Document your incident response contacts. Review NDPA obligations and schedule your annual privacy audit.
