Protect and manage your mobile apps on insecure customer devices

Build38 protection for confidential data on mobile devices is based on one powerful tool, one unified framework. It is designed for rich applications and used by their developers.

For Android and iOS

App Security Framework

For you it is collection of security functions every app needs. For developers it is an sofware development kit. For product managers it is application security. For users it is trust in you mobile business.

The Software Development Kit (SDK) is designed to integrate into your Android and iOS mobile apps during the development phase (security by design). The client library is built into the native code of an application.

In-App Protection

Multilayered Protection

Build38 combines different levels of mobile protection in its framework. Each layer represents a different security control. The level of protection is more powerful than traditional Android or iOS security mechanisms. Our protections is based on:

  • Resource Encryption (white-box cryptography)
  • Native Code Obfuscation
  • Debugging Detection and Emulation Detection
  • Privilege Escalation Detection and Bot Protection
  • Run-Time Detection (RASP)
  • Strong Device Binding

In-App Monitoring


The Enhanced Security Functions provide unique device fingerprinting and secure communication based on a client-and-server principle.

Secure Communication Channel

The secure communication channel between client and server offers a preventive security approach. In other words, network sniffing and reverse engineering is far more difficult. The T.A.K Server tracks the status of the T.A.K Client Library and the end device.

Threat Intelligence and In-App Reaction

High Level Mobile Security

After purchasing T.A.K an app service provider receives access to a specific T.A.K client library. By installing the development kit, developers integrate the framework into an app system during the design phase.

Once the app is published by the provider and users have downloaded the app from a dedicated source, the communication between T.A.K client and T.A.K server performs security checks every time each user starts the app.

The service provider can access the T.A.K dashboard at any time for security insights and relevant information on performance. As any other changes, T.A.K updates can be added to the same workflow as regular updates for mobile applications.

unified framework

T.A.K is not a process. It is a solution. One big idea, one system, one step.


T.A.K is designed for developers. The development kit is convenient and easy.


T.A.K layers protection. It works with several powerful systems at the same time.


The integration is efficient. Implementation and configuration is a matter of days.


T.A.K is independent and versatile. It runs in every environment.


T.A.K remains invisible, the app user experience will simply stay untouched.
