Best Secure File Transfer Software in 2026: Pricing & Comparison
We compared four secure file transfer tools on public pricing, transfer limits, encryption and compliance so teams can share files safely.
- Simple large-file sharing: WeTransfer — published Pro pricing for large transfers.
- Business file sync and share: Dropbox — published Business plans with transfer and storage options.
- Enterprise content and collaboration: Box — published Business and Enterprise pricing.
- End-to-end encrypted transfers: Tresorit — published plans focused on zero-knowledge encryption.
Secure file transfer software lets teams send large or sensitive files with encryption, access controls, expiration and audit logs instead of email attachments.
We evaluated the same fields for every vendor: published pricing and billing basis, free plan or trial, core focus, and the main limitation. Order is not a quality ranking. We sorted by lowest published starting price first where available.
