OVHcloud acquires Seald to strengthen its data security strategy

Roubaix – January 26th 2026 – OVHcloud, a global cloud player and the European Cloud leader, announces the acquisition of Seald, a French company focused on end-to-end encryption technologies. This is a major step forward in OVHcloud’s strategy to offer a trusted Cloud, combining security and regulatory compliance for the most critical use cases. With Seald, OVHcloud can integrate a cutting-edge technical building block for securing data through a “zero knowledge” model. 

Through this model, content is encrypted before being sent and can only be deciphered by the final receiving users on their devices. Neither the hoster, the editor, nor a system administrator can access this information. 

Encryption technology made simple for web apps and mobiles
The SDK developed by Seald benefits from the CSPN security visa delivered by the ANSSI, the French Cybersecurity Agency. It allows for quick integration of end-to-end encryption in web apps and mobile apps, with no expertise in advanced encryption required. The solutions allow for the management of access rights, encryption key rotation, multi-device management, and secure retrieval of private keys.

Reinforcing OVHcloud’s commitment to securing customer data
Through this acquisition, OVHcloud can natively integrate end-to-end encryption into its catalogue, complementing existing security propositions (Secret Manager, KMS, HSM) to offer a complete protection chain, from the backend to the user terminal. 

This acquisition will allow organisations:

• To design a differentiating technological offering to answer high-sensitivity use cases,
• To enrich and accelerate the development of ultra-secure solutions aimed at businesses and public organisations.
