Large-file transfer
Send up to 250 GB per file with resumable, chunked uploads and zero browser timeouts.
Features
Everything your auditor will ask about.
From boundary verification to forensic watermarks to SIEM-grade audit logs — built for the controls regulated teams already have to prove.
Capability catalog
Ten capabilities, one channel.
Recipient verification
Step-up auth at the boundary — SSO, MFA, device posture, or one-time passcode.
Watermarking
Visible per-recipient watermarks and invisible forensic marks for PDFs, images, and Office docs.
View-only delivery
Stream documents in-browser without download — useful for legal review and M&A diligence.
Expiring links
Time-bound or view-bound access. Revoke a link mid-flight and the document goes dark.
Tamper-evident audit log
Hash-chained events for every upload, view, download, and expiry — exportable to your SIEM.
Customer-managed keys
BYOK with AWS KMS, GCP KMS, Azure Key Vault, or HashiCorp Vault. We never see your plaintext.
Regional data residency
US-East, US-West, and US-gov data planes. Per-workspace residency override with no cross-region replication.
Branded recipient portal
Custom domain, your logo, your terms. Recipients never see the SEND-SECURELY.COM brand.
API + SFTP gateway
REST API, webhooks, and a fully-audited SFTP/AS2 gateway for legacy partner workflows.
