Audit Result

The Challenge

Processing payments across West Africa without a proper security foundation, the client was exposed. A third-party audit was looming in 10 weeks and they had no documentation, unpatched vulnerabilities, and no incident response plan. Failure would have cost them their payment processor contract.

Our Solution

We ran a full penetration test, identified and prioritised 34 vulnerabilities, and executed a remediation sprint. We also built their security documentation, implemented SOC monitoring, set up intrusion detection, and coached their team on secure development practices β€” all within the 8-week window.

Results

What we delivered

Achieved PCI-DSS compliance within 8 weeks of engagement

34 vulnerabilities identified and remediated before the audit

Passed the third-party security audit on the first attempt

Zero security incidents in the 12 months following deployment

β€œThey saved our contract. We wouldn't have passed without them β€” full stop.”
