Overview
Founded by Eric Lafortune in Leuven, Guardsquare builds security software that protects mobile applications at the code level. Its products, including ProGuard (the widely used open-source Java bytecode shrinker and obfuscator) and DexGuard, are used by banks, healthcare companies, and consumer app developers to prevent their applications from being reverse engineered or cloned.
The company raised $29M to expand its enterprise go-to-market and product capabilities. Guardsquare is recognized as a technical leader in mobile app hardening and competes in a global market where mobile security is increasingly critical given the sensitivity of financial and healthcare data processed on devices.
Based in Leuven, Guardsquare benefits from proximity to KU Leuven's research output and the broader Flemish deep-tech ecosystem.

- When we talk about mobile security, we often focus on the app itself. But every mobile app is just a client talking to backend APIs and attackers are starting to exploit that conversation. API security ensures the requests to your backend originate from genuine, unmodded instances of your mobile app. This is where app attestation comes in. Rather than assuming every API request is genuine, the app gathers security evidence within an attestation token it receives with the API request. The server then examines the token and
- Is the developer/AI honeymoon over? A new survey report from Atlassian suggests that reality is settling in. While over 80% of devs still agree that AI tools help them ship code faster and enable higher output without requiring longer working hours, the dramatic weekly time savings appears to be a thing of the past. Back in 2025, 68% of software developers reported saving 10 or more hours per week via AI. That number has come crashing down to just 26% in this year’s report. Industry analysts suggest that AI’s initial speed gains
- Automated mobile app security testing and code protections form the core tenets of a mobile application security strategy. Threat monitoring adds another layer giving your team visibility into the threats facing your mobile application. With threat monitoring, your team can: 📲 Integrate fraud data with backend systems for proactive responses 🎯 Distinguish between attackers and victims 🔐 Use telemetry data to prove regulatory compliance This video covers how threat monitoring can integrate into your broader mobile app

- You can lock your door and still have no idea whether someone tried the handle 30 times last night. That is the gap we talked about in our webinar, "Under Attack and Unaware." Mobile app protection detects a threat, reacts on the device, and moves on. It works, but it stays quiet. One detection is noise. Hundreds of them, sorted by threat type, app version, and device, show you where attackers focus. In our demo, one user profile had around 30 threat events across 8 to 12 device models, all from a single IP. No single event looked
