- Project mention: Guide to Seamless Data Security in Rails With Mongoid’s Automatic Encryption | dev.to | 2025-11-05

With the release of Mongoid 9.0, that same philosophy now extends to data encryption. Tasks that once required multi-step configurations can now be completed through a single model declaration. MongoDB’s Client-Side Field-Level Encryption (CSFLE) can now be seamlessly integrated into your applications, enhancing your data security with the ease and simplicity developers expect from Rails.
