How AI is used
PreEmptive is an application security suite designed to protect software from reverse engineering, tampering, and exploitation. It uses a layered approach to shield binary code, which may make it more difficult for users or machines to read and modify application logic.
The tool is built for developers and security teams working with .NET, Java, MAUI, and JavaScript. It offers specific products, including Dotfuscator, DashO, and JSDefender, to support desktop, mobile, cloud, and IoT environments.
Beyond renaming, the platform includes features to detect if a debugger is attached or if the code has been modified at runtime, which helps developers manage how their application behaves in production environments.
Buyers should confirm their specific platform needs, as the tool is organized into product lines based on the programming language and target OS.
Key Features
Code Obfuscation
Uses renaming and control flow obfuscation to make code more difficult for unauthorized users to read.
String Encryption
Encrypts sensitive values such as URLs and tokens, which are decrypted at runtime.
Tamper Detection
Includes traps that may alert the developer or shut down execution if the code is modified.
Debugger Removal
Removes information from production code that could be used to inspect the application.
Domain Locking
Binds JavaScript code to specific domains, which is designed to stop the app from running on unauthorized domains.
Sembi IQ
An AI engine that powers the platform's protection technology.
Agentless Protection
Embeds protection directly into the application without requiring agents on end-user devices.
Use Cases
Preventing Reverse Engineering
Applying obfuscation and renaming to help hide proprietary logic and intellectual property.
Protecting Mobile Applications
Hardening Android and MAUI apps to help prevent malware insertion and unauthorized probing.
Securing Client-Side JavaScript
Using JSDefender to conceal business logic and API usage in browser-based applications.
Runtime Threat Defense
Implementing debugger detection and tamper-proofing to help block exploits in production.
Integrations
- Visual Studio
