How do you ensure app security?

Foundation Security Measures

Strong security begins with robust architecture. At Full Scale, we implement industry-standard encryption protocols for all data transmissions. Our mobile developers use secure coding practices, including input validation, secure storage mechanisms, and protection against common vulnerabilities like SQL injection and cross-site scripting attacks.

Authentication and Authorization

We implement multiple authentication layers, including biometric verification, two-factor authentication, and secure token management. Our authorization protocols ensure users can only access appropriate data and functionality. This includes role-based access control and session management to prevent unauthorized access.

Data Protection Strategy

Data protection encompasses both storage and transmission. We employ end-to-end encryption for all sensitive data, using AES-256 encryption standards. Local data storage utilizes secure enclave technology on iOS and encrypted shared preferences on Android. Regular security audits and penetration testing help identify and address potential vulnerabilities.

Compliance and Standards

Our development processes adhere to international security standards, including GDPR, CCPA, and industry-specific regulations like HIPAA for healthcare apps and PCI DSS for payment processing. We maintain detailed documentation of compliance measures and regularly update our security protocols to meet evolving standards.
