Our verdict on Sefaly
Sefaly is a browser-based cloud storage service for individuals and small teams that need private file storage, encrypted sharing, and web-native access. Files are encrypted locally before upload using AES-256-GCM, while end-to-end encryption and a zero-knowledge architecture keep the service focused on privacy. Password-derived private-key protection and ML-KEM post-quantum key encapsulation add further protection around stored files and access.
The pricing structure is straightforward. The Free plan includes end-to-end encryption, post-quantum security, browser-based encryption, and email support, with a 2 GB storage tier. Pro costs USD 9.99 per month and adds priority email support, advanced sharing controls, and 1 TB of storage. Pro Plus costs USD 19.99 per month and includes priority support, advanced sharing controls, and 2 TB of storage. Paid plans are priced per month rather than per user. Storage quotas and file-size limits vary by plan.
Sefaly’s strongest fit is for buyers who prioritize browser-side encryption, zero-knowledge storage, and post-quantum protection over broad device coverage. Paid sharing controls make the service more suitable for private collaboration than the Free plan, while the web-only model keeps access centered on a browser. Choose Sefaly if encrypted web storage and sharing are the main requirements. Choose another service if desktop or mobile clients, versioning, or a broader platform ecosystem are essential.
