Guardsquare Tech Stack

Mobile app security platform built on ProGuard code hardening

Software Development Leuven 51–200 employees Founded 2014 Privately Held

Guardsquare develops mobile application protection tools centered on code hardening, reverse-engineering prevention, and runtime self-protection across iOS and Android. The company runs a mid-market engineering org (6 engineers across roles) supported by substantial marketing (4 headcount) and ops infrastructure, pointing to a sales-led GTM for an existing product line rather than new platform development. Active projects focus on compliance (ISO 27001, DORA readiness) and system resilience (backup/disaster recovery, security patch management), suggesting operational maturity in a regulated space; pain points cluster around audit readiness, regulatory drift, and post-acquisition integration.
