MASC is a mobile application security stack that protects mobile banking, payment, and enterprise applications against tampering, reverse engineering, and runtime attacks. It combines application encryption, configuration and secret protection, and Runtime Application Self-Protection (RASP) to defend mobile apps throughout their lifecycle, from distribution through to execution on end-user devices.

Unsung implements MASC for UK customers in financial services and enterprise environments where mobile applications handle sensitive transactions, authentication credentials, or regulated data and require protection beyond standard mobile platform security.

Mobile applications that handle banking transactions, authentication, or sensitive data operate in inherently hostile environments. Unlike server-side applications that run within controlled infrastructure, mobile apps are distributed to and executed on devices the organisation does not control. Attackers can decompile applications, extract embedded secrets, modify application logic, or intercept data at runtime.

Standard mobile platform security measures provide a baseline, but regulated organisations — particularly in banking and payments — need additional assurance that their applications resist tampering, protect embedded cryptographic material, and detect hostile runtime environments. Without dedicated mobile application security, organisations risk credential theft, transaction manipulation, and regulatory non-compliance.
