How is secure file sharing different from managed file transfer?

Managed file transfer automates large, scheduled transfers between systems over protocols like SFTP or AS2. Secure file sharing focuses on human-to-human exchange with per-recipient permissions and audit trails.

Do external recipients need to install software to open secure files?

Most modern secure file sharing tools provide a web portal or browser-based viewer so recipients can authenticate and open files without installing anything.

What encryption standard should secure file sharing tools use?

AES-256 for files at rest and TLS 1.2 or higher for files in transit are the current baseline standards. Check that the vendor does not hold the only copy of your encryption keys.

Q: What is secure file sharing?

Secure file sharing is the exchange of files using encryption and access controls to ensure only authorized recipients can open them. It typically includes audit logs that record who accessed each file and when.

Secure file sharing is the controlled exchange of files between users and external parties using encryption and access permissions to prevent unauthorized access. It protects files in transit and at rest, and provides audit trails for compliance.

What it does

Secure file sharing tools encrypt files before or during transfer and enforce access controls on who can open them. Common capabilities include:

Encrypting files at rest and in transit, sometimes into a proprietary format like a .cake file
Setting per-recipient permissions so different people see different content
Generating audit logs that record who accessed a file and when
Providing web portals, mobile apps, and CLI tools so users can share without bypassing controls
Watermarking documents and images to trace leaks back to a specific recipient
Redacting sections of a document for recipients who lack clearance for that content

Why teams buy it

Email attachments and consumer file-sync tools offer little control after a file is sent. Secure file sharing solves three problems:

Data exposure. Encryption stops third parties from reading intercepted files.
Access sprawl. Per-recipient controls and expiry dates limit how long a file stays accessible.
Audit requirements. Regulators in healthcare, finance, and government require proof of who accessed sensitive documents.

Teams that share contracts, financial reports, or patient records with external parties are the primary buyers.

What to look for

Encryption standard. AES-256 at rest and TLS in transit are the baseline.
Access control granularity. Can you set per-recipient or per-section permissions, or only folder-level?
Audit logging. Does the log capture downloads, previews, and failed access attempts?
