Vulnerability Disclosure & Security Policy
We take the security of our platform seriously. If you believe you have found a security vulnerability in any RxSure or QASTCO Limited system, we encourage you to report it to us responsibly.
How Does RxSure Protect Patient Data?
RxSure employs multiple layers of security to safeguard patient data at every stage of the prescribing workflow. All data transmitted between patients, prescribers, and our servers is encrypted using TLS 1.3, and data at rest is protected with AES-256 encryption. The platform is hosted on infrastructure that meets NHS Data Security and Protection Toolkit standards, and we maintain full compliance with the UK General Data Protection Regulation (UK GDPR) as enforced by the Information Commissioner’s Office (ICO). Access controls follow the principle of least privilege, with role-based permissions ensuring clinicians only see data relevant to their consultations. We conduct regular penetration testing and vulnerability assessments in line with NHS Digital cyber security guidance, and our compliance page provides full details.
