# KATVIO

> KATVIO is a French IT services agency founded in 2020, providing expert DevOps infrastructure, cybersecurity compliance (GDPR, SOC 2, ISO 27001), blockchain & Web3 infrastructure, AI/LLM security, and privacy-focused digital sovereignty solutions. We serve clients globally with specializations in multi-cloud architecture (GCP, AWS, Hetzner), Kubernetes orchestration, supply chain security, threshold cryptography, and confidential computing.

KATVIO is *not* a hosting provider or managed services platform. We provide consulting, implementation, and advisory services for organizations requiring advanced technical infrastructure, high-security standards, and innovative digital solutions. Our technology stack includes Go, Python, TypeScript, Terraform, Ansible, Kubernetes, and specialized cryptographic tools. Notable clients include Tezos Foundation, Marigold, LIGO, PeopleSpheres, Naval Group, and Blockchain Climate Institute.
