Direct peers

• Hub One: French operator (subsidiary of Groupe ADP) providing SD-WAN, managed networks, cybersecurity, and unified communications to mid-market and enterprise customers, with strong airport/regulated-vertical exposure. Comparable operator-services portfolio and SD-WAN/UC focus, but with stronger ties to large institutional buyers.
• Oceanet Technology: French managed cloud and IT services provider serving SMEs and mid-market with hosting, cloud, cybersecurity, and managed services from datacenters in France. Highly comparable in service portfolio (hosting + cloud + security), B2B segment focus, and French-sovereignty positioning.
• NXO: French integrator specialized in unified communications, collaboration, networking, and managed services for mid-market and enterprise customers. Comparable as a Cisco-aligned French UC/networking integrator targeting similar customer profiles, though larger in headcount and national footprint.
• Waycom: French managed network and SD-WAN operator providing connectivity, security, and cloud services to mid-market and enterprise clients. Comparable SD-WAN-led B2B operator model with similar customer size profile, though with broader geographic coverage.
• Foliateam: French managed services provider (operator status) offering SD-WAN, VoIP/unified communications, cloud hosting, and cybersecurity to mid-market and enterprise customers with multiple French datacenters. Closely comparable in operator + cloud + UC + security mix and French SME/institutional target market.

Regional players

• Celeste: French B2B telecom operator focused on fiber connectivity, cloud, and managed services for SMEs and mid-market, headquartered outside Lyon. Comparable as a regional French operator with own fiber infrastructure and a similar SME/institutional client base, though geographically centered in Rhône-Alpes rather than Alsace.
• Alsatis: French operator specialized in satellite, radio, and hybrid connectivity for enterprises and public sector, particularly underserved and rural areas. Comparable as a French B2B connectivity operator with regulatory/certified positioning, though with a different technological focus (satellite/radio) than DIATEM's fiber-first approach.

Broad incumbents

• Capgemini Engineering (Altran heritage): Global IT services and engineering firm with significant French footprint delivering cloud, networks, cybersecurity, and digital transformation to large enterprises. Overlaps with DIATEM's web development pole and infrastructure services at the enterprise end, but at substantially larger scale and broader portfolio.
• Bouygues Telecom Entreprises: B2B arm of Bouygues Telecom offering fiber, SD-WAN, mobile, cloud, and cybersecurity to French enterprises and public sector. Direct overlap with DIATEM's operator and connectivity services, but with national coverage, larger engineering bench, and stronger brand recognition.
• Orange Business: Global B2B division of Orange providing enterprise connectivity, SD-WAN, cloud, cybersecurity, and managed services across France and internationally. Overlaps substantially with DIATEM's portfolio but operates at vastly larger scale with national/global coverage that DIATEM cannot match.
