What Celeonet does

Celeonet is a privately held French B2B cloud hosting and managed-infrastructure provider founded in 2003 and headquartered in the Paris region (Vitry-sur-Seine / Choisy-le-Roi), with a secondary office in Lyon (Chaponost). The company operates an owned Tier 3 datacenter in the Paris region on HPE servers and Juniper networking, and holds ISO/IEC 27001:2022 certification plus HDS (Hébergeur de Données de Santé) certification at levels 2-6, enabling it to host regulated French health data. Its product portfolio spans five cloud tiers (Cloud Public, Cloud Privé, Cloud Event, Cloud HDS, Cloud Starter), dedicated physical servers, managed Microsoft 365, Synology external backup, on-site IT management, and a high-touch DSI externalisée (outsourced CIO) offering aimed at SMEs.

Underlying technology combines a proprietary Web Application Firewall developed in-house, a custom-built client extranet/management interface, and deep Linux expertise (Debian, Ubuntu, CentOS, with Apache/Nginx, MySQL/PostgreSQL, and Proxmox virtualisation). Celeonet guarantees a 99.9% SLA on dedicated servers and targets 99.99% availability on cloud, with anti-DDoS and dedicated IP as standard. Sovereignty is the central commercial wedge: infrastructure is 100% French, fully subject to French and EU law, explicitly positioned as immune to the US Cloud Act, and marketed against hyperscaler egress fees and opaque billing.

The business model is predominantly recurring subscription revenue across cloud, dedicated servers, managed services, Microsoft 365 resale, and externalised backup, supplemented by project-based professional services (audit, migration, MCO) and strategic DSI retainers. Go-to-market is direct B2B sales-led (phone-first, with a dedicated account manager per client) combined with a content-driven SEO hub targeting French-language queries on RGPD, NIS 2, HDS, Cloud Act, and DORA. Customers are concentrated in France and span healthcare (HDS-mandated), French SMBs/mid-market, e-commerce/SaaS platforms with high-traffic workloads, public-sector/regulated industries, financial services facing DORA, and web agencies/e-merchants. The company publicly claims 20+ years of operation and 1,000+ clients, but is run by a lean ("human-scale") team of 1-10 with no disclosed funding, M&A, or institutional ownership.

Expansion highlights5 records

Direct peers

• OVHcloud: Largest French/European sovereign cloud provider offering public cloud, private cloud, dedicated servers, and HDS-certified hosting. Direct competitor to Celeonet across virtually all product lines but at vastly greater scale and with global reach.
• Scaleway: European sovereign cloud provider (Iliad Group) offering bare-metal servers, public cloud instances, and managed Kubernetes with datacenters in France and the Netherlands. Comparable to Celeonet on the sovereignty/European-data-residency axis but with hyperscaler-style product breadth.
• Outscale: French sovereign cloud provider owned by Dassault Systèmes, offering IaaS/PaaS with SecNumCloud and HDS certifications. Direct competitor in the regulated French cloud segment, particularly for healthcare and public-sector workloads.
• Ikoula: French hosting and managed cloud provider with owned datacenters, dedicated servers, and HDS-certified hosting. Closely comparable in size, product mix, and target customer profile to Celeonet — both serve French SMBs with sovereign infrastructure.
• Clever Cloud: French PaaS provider offering managed hosting for applications (Java, Node.js, PHP, Ruby, etc.) on European sovereign infrastructure. Comparable target market (French/European developers and SMBs) with a managed-services-led model.
• Online.net (Scaleway): French dedicated-server and hosting brand (now part of Scaleway/Iliad), historically positioned for tech-savvy SMBs and developers. Overlaps with Celeonet's Serveur Dédié offering at lower price points.
• Gandi: French domain registrar and cloud/hosting provider offering VPS, dedicated servers, and managed hosting. Comparable French SMB/mid-market target audience with sovereign infrastructure, though more developer-leaning than Celeonet.

Regional players

• Infomaniak: Swiss sovereign cloud and hosting provider offering cloud servers, web hosting, and collaborative tools from Swiss datacenters. Comparable sovereign-cloud and SMB-focused positioning, but operating in Switzerland rather than France.

Broad incumbents

• Amazon Web Services (AWS): Global hyperscaler offering cloud compute, storage, and managed services including AWS Europe (Paris) regions. Indirect competitor when French buyers weigh sovereignty vs scale; serves as the benchmark Celeonet positions against on pricing and elasticity.
• Microsoft Azure: Global hyperscaler with Azure France regions and the dominant Microsoft 365 platform that Celeonet resells. Competes with Celeonet on cloud infrastructure and is simultaneously a key product partner through the managed Office 365 service.
