What Guardis does
Guardis SRL is a privately held boutique cybersecurity and DevSecOps services firm founded in 2004 in Hannut, Belgium. The company serves critical infrastructure operators, SaaS scale-ups, defence primes, and aeronautic and rail industrial clients across Europe, delivering senior-only engineering capacity across four integrated practices: Cybersecurity & Audit (pentesting, vulnerability assessment, NIS2 and ISO 27001 advisory), DevSecOps & Automation (CI/CD, infrastructure orchestration, monitoring), Cloud & Infrastructure (architecture, deployment, day-2 operations), and R&D & Innovation (publicly funded programs CYRUS, CRESCENDO, V4F, EAMSDI).
The technology foundation is deliberately cloud-agnostic and open-source: Linux, Kubernetes, Terraform, Prometheus, Grafana, Kafka, ELK, Ansible, GitLab CI, Azure Pipelines, with industrial protocol support via MQTT and Kafka for IT/OT integration. Guardis co-develops a proprietary cyber-physical security testing platform through the CYRUS and CRESCENDO programs with tier-1 industrial partners including Thales, FN Herstal, John Cockerill, Alstom, and AISIN, alongside academic partners UCLouvain, CETIC, and Multitel within the Walloon Region R&D ecosystem.
Revenue is generated through two engagement models sold on multi-year contracts: Expertise & Advisory (staffing, technical and managerial audits, NIS2 and ISO 27001 advisory, CxO-as-a-Service, embedded senior engineers) and Managed Operations (plan-design-deploy-operate with 24/7 monitoring, incident remediation, and continuous hardening). Pricing is quote-based and not publicly disclosed; the sales motion is direct, initiated via a 30-minute scoping call. Named reference engagements include a decade-long partnership with Proxyclick (Eptura) for multi-cloud DevSecOps and a ~300-VM zero-downtime migration to Azure, and an IT/OT infrastructure mandate for Safran Blades supporting aeronautic production lines. Leadership documented in the structured data identifies Christian Mack as Cybersecurity & Infrastructure Lead, while a separate leadership listing also references Daniel Bartz as CEO and Founder.
