AppSuit PremiumProtecting mobile apps from critical threats
Protect your apps end to end with powerful code obfuscation and anti-tampering technology. GS Certification Level 1 — an on-premise mobile app security solution
Mobile app security is no longer optional.
As mobile services expand, most security incidents now begin with the app. Apps can be decompiled to expose their source code, which then enables tampering, malicious code injection, and the disabling of security features.
For financial, public-sector, and platform services in particular, these attacks go beyond simple hacking — they lead directly to service outages, data breaches, and financial loss.
Meanwhile, security regulations from authorities such as the Financial Security Institute and the Ministry of the Interior and Safety keep tightening, making app security a mandatory compliance requirement rather than an optional feature.
A vulnerable app invites reverse engineering — exposing core logic and APIs and enabling tampering — which becomes a direct business risk. AppSuit Premium applies unified app security through a single SDK, blocking threats before they happen.
Decompilation
Source code exposed via binary reverse engineering
Tampering
App logic modified and malicious code injected
Security Bypass
Security features circumvented and authentication logic removed
Damage
Data breaches · financial loss · service outages
Anti-tampering and code protection are security measures legally required for financial and personal-data services.
