GuardSquare

GuardSquare provides a suite of security solutions for native and cross-platform mobile applications, serving industries such as finance, e-commerce, gaming, and healthcare. The company's business model is centered on selling software licenses and providing expert support. In January 2019, GuardSquare secured its first institutional funding round of $29 million, led by Battery Ventures. Subsequent investments include an undisclosed amount from Verdane in July 2025. The company has also grown through acquisitions, including App-Ray in 2020 and Verimatrix's Extended Threat Defense (XTD) division in 2026.

The product portfolio offers multi-layered security that integrates throughout the software development lifecycle. Key products include: * **DexGuard:** Protects Android applications against reverse engineering and tampering through code hardening, obfuscation, encryption, and Runtime Application Self-Protection (RASP). It is designed to be backward compatible with ProGuard configurations. * **iXGuard:** Provides similar comprehensive protection for iOS applications, defending against both static and dynamic analysis with features like code virtualization, name obfuscation, and runtime integrity checks. * **AppSweep:** A mobile application security testing (MAST) tool that helps developers find and fix security vulnerabilities early in the development process. * **ThreatCast:** A real-time threat monitoring service that gives visibility into active attacks on applications in production. * **ProGuard:** The foundational open-source tool for shrinking, optimizing, and providing basic obfuscation for Java and Kotlin bytecode.
