Oceanet Technology

What Oceanet Technology does

Oceanet Technology is a French B2B telecom operator and managed services provider, operating under the Celeste brand with headquarters in Champs-sur-Marne (Île-de-France) and Saint-Herblain (Loire-Atlantique). The company owns and operates a 13,000 km proprietary fiber optic network across France and four ISO 27001 and HDS-certified datacenters, delivering dedicated and shared fiber internet, multi-site networking (VPN, MPLS, SD-WAN), hosted telephony, mobile services, private/hybrid/public cloud, colocation, disaster recovery (PRA/PCA), and cybersecurity services including penetration testing, vulnerability scanning, anti-DDoS, and DevSecOps consulting. A flagship bundled offering, 'Compte Internet Sécurisé,' combines connectivity, security, cloud, and telephony into a single managed proposition for SMEs and mid-market clients.

The business model is recurring-revenue weighted, built on annual subscriptions for connectivity and telephony contracts, managed services for cloud and cybersecurity, and add-on pricing for backup and colocation. Enterprise and ETI customers receive quote-based bespoke pricing via dedicated field sales and account managers; SMBs can self-provision standardized services through the e-celeste.fr online store. Distribution is augmented by a reseller and partner program plus a wholesale offering for other operators. The company maintains a wholly-owned cybersecurity subsidiary (NBS System, acquired 2016), Swiss B2C (VTX Télécom) and Swiss B2B (Celeste.CH) subsidiaries, and serves customers including Total, Veolia, Somfy, VYV, and Banque across PME, ETI, Grand Compte, Collectivité, Healthcare, Retail, Industry, and Energy verticals.

Strategically, Oceanet Technology / Celeste competes on infrastructure ownership, regulatory certifications (HDS for healthcare data, ISO 27001 for information security), and integrated service delivery rather than on price or AI-native differentiation. The company has been an active operating business since 2001, with recurring investment from CM CIC Investissement (2012, 2016), ongoing product launches, and ESG commitments including Engagé RSE Niveau Confirmé and the 2025 Carbon Balance publication. Revenue, funding scale, and headcount growth metrics are not publicly disclosed.
