Regain Control of
Your Cloud

Sefirot is a French cloud consulting firm based in Paris, specialized in Cloud, DevOps, CI/CD, FinOps, Sovereign Cloud, and Architecture. We support large enterprises (LVMH, Société Générale, Airbus, Engie, Canal+...) and scale-ups in mastering their cloud infrastructure, reducing costs, and accelerating deployments.

Unlike large ESNs, Sefirot operates with small expert teams, without padding. Each engagement starts with a 5-day flash audit that produces a concrete, prioritized action plan — not 200-page slide decks. We measure three indicators before/after: cost, stability, and time-to-production. The goal is to make you autonomous, not dependent.

Sefirot supports scale-ups and tech SMEs as well as large groups. Our modular approach — flash audit, strategic recommendations, collaborative implementation — adapts to very different contexts in terms of size and cloud maturity.

Sefirot applies a 3-phase FinOps methodology: first a visibility audit (who spends what, where, and why), then an optimization phase (rightsizing, reserved instances, removing orphaned resources), and finally governance implementation to sustain the gains. Our clients typically see 25 to 40% reduction in their cloud bill within 90 days.

Sefirot covers all major clouds: AWS, Azure, GCP as well as French sovereign clouds Scaleway and OVHcloud. We are equipped with market FinOps platforms (CloudHealth, AWS Cost Explorer, Azure Cost Management...) and can audit multi-cloud environments.

Sefirot designs and implements industrialized CI/CD pipelines: from continuous integration (automated tests, quality gates, SAST/DAST) to continuous deployment (GitOps, Kubernetes, ArgoCD, Terraform). The goal is to reduce time-to-production from days to minutes while reducing human error risk.

Sefirot advocates and implements Infrastructure as Code with Terraform as the primary standard, complemented by Ansible for configuration, Helm for Kubernetes, and Pulumi in certain contexts. IaC ensures reproducibility, change traceability, and facilitates security audits.

Sefirot operates in embedded coaching mode: our engineers work alongside your teams, transfer best practices, and document processes. At the end of the engagement, your teams have the keys to maintain and evolve the platform autonomously. We don't create dependency.

Sovereign Cloud refers to infrastructure hosted and operated on French or European territory, under GDPR jurisdiction, beyond the reach of the US Cloud Act. It is essential for companies handling sensitive data (healthcare, finance, defense, personal data) or subject to regulations like SecNumCloud, HDS, or the NIS2 directive.

Yes, we support migration to these sovereign clouds. We adopt a pragmatic approach: identify critical workloads requiring sovereignty, migrate those to a French cloud, and keep the rest on the most suitable hyperscaler (AWS, Azure, GCP).

Sovereignty is not a barrier to performance. Sefirot designs intelligent hybrid architectures: critical data and regulated processes are isolated on the sovereign cloud, while less sensitive workloads benefit from hyperscaler power. This approach combines strict compliance, time-to-market, and performance.

Sefirot recommends architectures that are resilient, scalable, and manageable. Depending on context, this can range from microservices on Kubernetes to serverless on AWS Lambda, or managed PaaS. We select technologies based on actual risk, team skills, and business constraints — not trends.

Security is built in from the start at Sefirot (Security by Design): network segmentation, least privilege principle (IAM), encryption of data at rest and in transit, secrets management (Vault, AWS Secrets Manager), and security scan integration in CI/CD pipelines. We also perform cloud security audits to identify configuration vulnerabilities.

Every collaboration starts with a 5-day flash audit: analysis of your current infrastructure, identification of risks, cost overruns, and bottlenecks. At the end of this audit, you receive a concrete, prioritized, co-constructed action plan. You can then choose to commission us for implementation or execute the plan internally.
