Case Study: Enhancing Security Posture for QHS Labs

QHS Labs is a health technology company based in the United States, focused on innovating digital healthcare solutions that prioritize data integrity, patient confidentiality, and regulatory compliance. As part of their mission to deliver cutting-edge medical applications, QHS Labs emphasizes the importance of aligning with strict compliance standards such as HIPAA and NIST 800-53.

Red Threat Cyber Security (RTCS) was contracted to perform a comprehensive security engagement for QHS Labs, which began with a meticulous penetration testing and vulnerability assessment phase. The engagement evolved into a broader Managed Security Services Partnership (MSSP), involving continuous security monitoring, DevSecOps integration, and regulatory compliance alignment.

When QHS Labs approached us, they were seeking a trusted security partner to help them identify and remediate vulnerabilities within their application and infrastructure. Additionally, they required guidance on aligning their operational environment with industry standards, including HIPAA, NIST, and GDPR, while preparing to scale securely.

We initiated our partnership with a black-box and grey-box penetration test targeting both external and internal attack surfaces. Our pentest engagement assessed the application, server configurations, APIs, and cloud assets. During this phase, we maintained close collaboration with their technical team, ensuring findings were contextualized within their development workflows.

Following the pentest, we delivered a detailed technical report outlining all findings based on CVSSv3 scoring, complete with proof-of-concept evidence, exploit paths, business impact analysis, and prioritized mitigation strategies.

Upon completion of the assessment, QHS Labs chose to extend the engagement by onboarding RTCS as their dedicated cybersecurity partner. Our team provided:

• Continuous monitoring and threat detection through our MSSP framework
• Security integration into CI/CD pipelines (DevSecOps)
• Policy drafting for HIPAA and NIST 800-53 compliance
• Consultation on GDPR readiness and secure data handling practices
• Incident response advisory and readiness evaluations

The comprehensive security assessment significantly enhanced QHS Lab’s cybersecurity posture, resulting in tangible improvements:

• Several critical vulnerabilities were discovered and remediated before they could be exploited in the wild
• Application architecture was hardened based on our risk-based recommendations
• Security best practices were integrated into development workflows, reducing technical debt and future exposure
• QHS Labs achieved higher assurance in handling Electronic Protected Health Information (ePHI), aligning with HIPAA and NIST security control baselines

Through this rigorous security enhancement initiative, several critical lessons emerged:

• Continuous Vigilance: Cyber threats evolve rapidly, necessitating regular and proactive security testing and vigilance.
• Security-by-Design: Integrating comprehensive cybersecurity measures at every development stage enhances overall platform resilience and reliability.
• Controlled Transparency: While sharing general insights strengthens industry credibility and thought leadership, protecting specific operational and technical details safeguards against potential adversarial exploitation.

This engagement demonstrated the value of a strategic, hands-on cybersecurity partnership. Through technical precision and regulatory insight, RTCS helped QHS Labs build a secure foundation for scaling their health tech offerings with confidence
