Keystone Solutions Tech Stack

IT consulting and custom software delivery for enterprise modernization

Information Technology & Services Brussels, Brussels 51–200 employees Founded 2014 Privately Held

Keystone Solutions pairs IT strategy and software engineering to help enterprises migrate and modernize legacy systems. The tech stack—Java, Spring Boot, Kafka, Docker, Kubernetes—reflects a strong infrastructure-as-code discipline; active adoption of Prisma Access/Cloud and Azure Kubernetes Service signals a pivot toward zero-trust security and container orchestration at scale. Hiring velocity is accelerating with a 19:8 engineering-to-ops ratio and a senior-heavy mix (23 of 40 roles), indicating they are ramping execution on complex cloud and security migrations rather than scaling sales.
