//01The challenge

The client, a rapidly growing online trading platform, was handling millions of daily transactions across global markets. With a user base exceeding one million accounts, the stakes were considerable. They faced increasing threats from sophisticated attacks targeting financial data, session tokens and API endpoints.

Internal audits had revealed several potential breach vectors in legacy infrastructure. The authentication system lacked modern multi-factor protection, encryption methods were outdated, and insufficient real-time monitoring left them exposed to both external actors and internal compliance risk.

Adding urgency, the company needed PCI DSS compliance to maintain regulatory standing and continue processing payments — and their existing security infrastructure could not keep pace with the threat landscape.

//02What we built

The solution

_01

Penetration testing & vulnerability assessment

Exhaustive testing across APIs, web applications and mobile clients. Forty-seven critical vulnerabilities identified and remediated before they could be exploited.

_02

Multi-layered security architecture

Defence in depth with WAF, DDoS protection, network segmentation and zero-trust access control — each layer designed to operate independently and prevent cascade failure.

_03

Real-time threat monitoring

A 24/7 Security Operations Centre with AI-powered anomaly detection, SIEM integration and automated incident response workflows neutralising threats in under 60 seconds.

_04

PCI DSS compliance framework

A compliance programme built from the ground up covering encryption at rest and in transit, access control, audit logging and secure key management across all twelve requirements.
