Security Case Study

Security Hardening

How we conducted deep vulnerability penetration testing and hardened systems for a healthcare provider to achieve zero critical threat markers.

🔒
The Challenge

Unprotected Patient Records & API Flaws

A rapid-growth healthcare mobile portal needed to validate their cybersecurity posture ahead of a critical series-A funding round and regulatory health audits. Initial tests showed vulnerability to database injection vectors and unprotected API endpoints that could theoretically allow leaking patient records.

They engaged Oksina to execute an end-to-end white-hat pentest, identify critical leak vectors, resolve vulnerabilities, and secure HIPAA regulatory compliance.

The Solution

Penetration testing & zero-trust network

🔍

White-Hat Pentest

Executed simulated database attacks, network port scanning, and API payload manipulation to map out all vulnerability coordinates.

🛡️

Cloudflare WAF

Configured Cloudflare Web Application Firewall rules to block malicious injection attempts, cross-site scripting (XSS), and DDoS spikes.

🔑

Zero-Trust Access

Implemented strong multi-factor authentication (MFA) and isolated administrative SSH panels behind secure VPN walls.

Measurable Impact
