Yes, Odoo supports encryption for data both at rest and in transit:

1. Encryption at Rest: Customer data is stored in a dedicated database with complete data isolation. We ensure data encryption at rest within our infrastructure, as part of our security measures​​.
   
   
2. Encryption in Transit: We ensure secure transmission of data by using HTTPS for all communication, ensuring encryption in transit. This applies to both customer interactions with Odoo Cloud services and internal communications within the Odoo infrastructure​​.
