Cyllene

What Cyllene does

Cyllene is a privately held French digital transformation operator founded in 1986 and headquartered in Nanterre/Paris, with 400+ specialists distributed across 13+ regional offices in metropolitan France plus a Papeete (French Polynesia) location. The company sells a comprehensive B2B services portfolio organized around five pillars — Cloud (private, public, hybrid, and managed services), Infrastructure (architecture, MCO, service platforms), Data & AI (data lake, ETL, BI, sovereign AI), Application (custom development, interfaces, Sylius e-commerce, replatforming, TMA), and Cybersecurity (SOC, audits, GRC, endpoint protection) — underpinned by owned French datacenters exceeding Tier III standards and a 24/7 managed SOC operated by French teams.

The technology stack combines Cyllene's own product family (AlterStor, AlterBackup, AlterProtect, Alter 365, Alter Desktop, Alter Drive, AlterParc, SOC Managé Français, IA Souveraine) with deep partnerships across Microsoft, AWS, Google Cloud, Proxmox (exclusive French training authorization), Sylius (official partner), NetApp, Fortinet, Palo Alto Networks, CrowdStrike, Veeam, and Nutanix. Cyllene is certified under SecNumCloud, HDS, ISO 27001, SOC 1 Type II, SOC 2 Type II, and ARCEP, positioning it as one of the few French operators able to serve regulated workloads in healthcare, finance, and the public sector.

Revenue mechanics blend professional services (audits, consulting, custom development, TMA), recurring managed services (24/7 infrastructure and SOC with 99.995% availability guarantees), subscription cloud and storage (private cloud, AlterStor, AlterBackup, sovereign AI), telecom/connectivity services, and training/licensing (sole French official Proxmox provider). The go-to-market is enterprise field sales with customized multi-year contracts and no public pricing, supported by free 45-minute e-commerce diagnostics and complimentary security audits (valid through March 2026) as lead-generation tools. Customer concentration is moderate and dispersed across luxury, insurance, media, utilities, hospitality, automotive, fintech, and restaurant verticals, with named logos including Groupama Loire Bretagne, Lagardère, SAUR, BodemerAuto, Bollinger, Petit Bateau, Buffalo Grill, Verspieren, Havas, Breguet, Jaquet Droz, and Louis Roederer.

Scale indicators9 records

Recent moves6 records

Expansion highlights5 records

Direct peers

• Devoteam: French-headquartered IT consulting and digital transformation firm with similar cloud, data, and cybersecurity offerings across mid-market and enterprise French accounts. Comparable in size, services portfolio, and go-to-market focus on French enterprise digital transformation.
• Econocom: French IT services and managed services provider with overlapping cloud, cybersecurity, and digital workplace offerings for French enterprises. Comparable customer segment and delivery model to Cyllene.
• OVHcloud: French sovereign cloud provider competing directly with Cyllene's Hébergement Souverain / Cloud Privé offerings. Targets the same SecNumCloud-certified, data-residency-focused French enterprise buyer, though OVHcloud is more infrastructure-only while Cyllene adds managed services and integration.

Broad incumbents

• Sopra Steria: Major French IT services and digital transformation firm serving large enterprises and public sector. Overlaps with Cyllene across cloud, security, data, and application services, but operates at significantly larger scale and broader European footprint.
• Capgemini: Global IT services leader with French roots, offering overlapping cloud, cybersecurity, data/AI, and digital transformation services. Competes for the same French enterprise accounts but at much larger scale and global delivery footprint.
• Orange Business Services: Telecom-led cloud, connectivity, and managed services arm of Orange, competing with Cyllene on cloud hosting, SD-WAN, managed services, and cybersecurity for French enterprises — and benefiting from the Orange network backbone.
• Atos: Historically one of France's largest IT services firms, now undergoing restructuring. Overlaps with Cyllene across cloud, security, data, and managed infrastructure services for French enterprise and public-sector clients.

Emerging players

• Scaleway: French sovereign cloud provider (backed by Iliad) competing in the same SecNumCloud-certified infrastructure niche as Cyllene. Focused on cloud infrastructure rather than the broader managed services portfolio, but increasingly overlapping in sovereign and AI workloads.

Regional players

• T-Systems: Deutsche Telekom's IT services arm offering comparable cloud, managed services, and sovereign/regulated hosting in Germany. Not a direct French competitor, but a relevant European peer for cross-border benchmarking on sovereign cloud and managed services positioning.
• Bechtle: Germany-headquartered IT services and systems integrator with similar multi-vendor cloud, security, and managed services portfolio. Operates primarily in DACH rather than France, but a useful comparator on European mid-market IT services economics.
