V-OS Mobile App Protection

V-Key is a software-based digital security company headquartered in Singapore and founded in 2011. It protects digital identity, authentication and mobile apps for banks, payment gateways, government agencies, fintechs, telcos and healthcare providers, replacing costly hardware tokens and secure elements with software that meets comparable security standards.

V-OS Mobile App Protection is delivered as a secure SDK embedded in Android, iOS and HarmonyOS apps. It is built on V-OS, a patented Virtual Secure Element that isolates cryptographic keys and sensitive processes inside the app. The product combines code obfuscation, runtime defense, device integrity checks, anti-keylogger and overlay protection, and keeps working on rooted or jailbroken devices. Threat insights from live attacks are fed into the customer's fraud and security systems, and defenses can be updated over the air.

• Virtual Secure Element: Isolates keys and cryptographic operations in a patented software sandbox.
• Runtime defense: Detects and blocks tampering and hooking while the app is running.
• Obfuscation and integrity checks: Hinders reverse engineering and verifies app and device integrity.
• Anti-keylogger and overlay protection: Stops credential capture and screen overlay fraud.
• Threat insights: Streams live attack data into fraud prevention and security systems.
• OTA updates: Updates defenses over the air across Android, iOS and HarmonyOS.

A Vietnamese bank can embed the SDK in its mobile banking app to block overlay and remote access fraud. An e-wallet can keep transaction signing keys protected even on rooted phones. A public service app can verify app and device integrity before granting access to citizen data.

Banks and super apps can protect mobile transactions without relying on hardware tokens or device secure elements. Protection continues on rooted or jailbroken phones, which reduces exposure from compromised devices. Real-time threat insights strengthen existing fraud detection systems. The SDK is designed for fast integration into enterprise development workflows, and V-OS is reported in use on more than 200 million devices worldwide.

Mobile banking fraud using malware, screen overlays and remote access tools is rising across Southeast Asia, and regulators are tightening requirements for app security and strong authentication. Banks and e-wallets in Vietnam and the region are moving from SMS OTP to app-bound authentication and in-app protection.
