Zertificon Solutions GmbH Tech Stack

PKI and email encryption platform for regulated industries

Software Development Berlin 51–200 employees Founded 2004 Self-Owned

Zertificon manufactures IT security software focused on PKI certificate management and encrypted communications, with particular depth in energy, finance, and healthcare sectors. The tech stack is Java/Spring-based with recent Kubernetes adoption alongside Docker containerization, and the project roadmap emphasizes modernization: microservice architecture, CI/CD pipeline development, and legacy system integration—typical of a maturing security vendor moving from monolithic appliances toward cloud-native deployment. Hiring remains heavily weighted to engineering and operations, suggesting sustained infrastructure investment rather than sales expansion.
