Mobile App & Web Penetration Testing

I'm seeking a professional penetration testing specialist that can review my mobile app (compatible with iOS and Android) and web platform. The primary areas of focus will be:

- Authentication and authorization: I want to ensure the system is secure and users cannot access unauthorized areas.
- Data encryption: The sensitive information stored on the app and web should be thoroughly protected.
- Network vulnerabilities: The system's network should be checked for weak points or potential breaches.

These are crucial given that the project must adhere to a series of compliance standards such as PCI DSS, HIPAA, and GDPR. I need the assurance that the app and the web platform are safe and compliant with these standards.

Ideal candidates should have proven experience in penetration testing of mobile apps and web platforms, with a solid understanding of PCI DSS, HIPAA, and GDPR compliance standards. A certification in ethical hacking or similar would be a plus. A strong track record in identifying security vulnerabilities and providing actionable recommendations is a must.
