MASC: MOBILE APP SECURITY FOR REGULATED APPS

 

MASC is Cryptomathic’s mobile app security platform, combining in‑app protection (MASC Core SDK) with server‑side verification and policy (MASC Assurance) - to reduce mobile fraud, protect secrets and sessions, and help teams support audit readiness without slowing development.

WHY APP-LEVEL SECURITY STILL FAILS WITHOUT IN-APP PROTECTION

 

Mobile apps operate in hostile, unmanaged environments. OS-level controls, backend fraud systems, and network security help - but they can’t stop attackers who manipulate the app while it is running, or who extract secrets through reverse engineering. This gap is where mobile fraud, account takeover enablement, and audit findings often originate.

Runtime Defense

Runtime attacks bypass perimeter and backend controls (hooking, overlays, instrumentation, replay).

Picture1

Device Exposure

Tokens, secrets, and IP are exposed on compromised devices.  

Picture21

Compliance Pressure

Mobile compliance frameworks increasingly expect in-app controls and demonstrable evidence.  

Picture13

Operational Tension

Development teams struggle to balance UX, security, and release velocity.

WHAT IS MASC?

MASC is a two-layer approach to mobile app security:

1. MASC Core (in-app SDK) embeds runtime protection, anti-tamper controls, secure storage, and network hardening directly into iOS and Android apps.

2. MASC Assurance (server-side) verifies mobile integrity signals, applies policy, and issues backend trust decisions - enabling centralized reactions and audit-grade visibility.

MASC is designed to help security teams reduce client-side risk without forcing major architectural change - and to help product teams ship quickly while keeping high-value flows protected.

Key Outcomes:

  • Detect and mitigate runtime manipulation and malware in the mobile channel
  • Protect code, assets, credentials, and sessions on the device
  • Strengthen API communication and session integrity
  • Support audit readiness through documentation, mappings, and evidence options

EXTENDING IN-APP PROTECTION WITH SERVER-SIDE VERIFICIATION

 

When paired with MASC Assurance, runtime signals from the SDK are verified server-side and evaluated against security policy. This enables device binding, centralized reactions, proof-of-possession and audit-grade evidence - without requiring an app redeploy.

Key Outcomes:

  • Over-the-air policy updates (govern reactions centrally)
  • Centralized reactions to mobile threats (allow / crash / report / block)
  • Reduced fraud exposure and faster audit preparation through consistent evidence

Why Cryptomathic

WHY IS IT CRUCIAL TO HAVE THE HIGHEST LEVELS OF MOBILE APP PROTECTION?

Native mobile apps provide a superior user experience of native apps but escape your control once downloaded, opening possibilities for exploitation. Unauthorized access to sensitive information on mobile devices can not only make customers and businesses vulnerable. It could pose national security risks. If a passport stored in a digital wallet is compromised, it affects the ability of border force agents to correctly identify someone crossing the border. Bad actors could illegitimately cross nations or genuine citizens could be denied entry. Mobile app protection is not just a question of convenience. It is about managing all modern security risks to keeping sensitive data safe. If you work in highly regulated sectors, your apps will contain financial, health, personal or similarly sensitive data. Default vendor solutions are not enough and breaches don’t just threaten to halt your revenue streams, they can destroy your reputation and lose you customers. Work with the global specialists to set threat parameters exactly as you wish and provide the highest levels of protection.
