Kiteworks delivers regulated file exchange with a heavyweight platform deployment. SendSafely is built into the tools your team already uses — encryption that lives inside Outlook, Gmail, Zendesk, Salesforce, Intercom, Freshdesk — and a split-key architecture that means even SendSafely can't read customer content.
A side-by-side picture of what Kiteworks is built for, and where SendSafely is built differently.
Each row reflects how the two products approach the same problem. Both companies maintain their own certifications and audit programs — consult each vendor's public documentation for current capabilities.
| Feature | SendSafely | Kiteworks |
|---|---|---|
| Client-side encryption (before upload) | Yes — OpenPGP, every file | Yes, with HSM-backed encryption at rest |
| Split-key architecture (no admin path) | Yes — sender + platform halves never combined server-side | Admin-managed encryption; varies by configuration |
| Deployment model | Cloud-native, native helpdesk + email integrations | Platform deployment; on-prem, private cloud, or hosted |
| Recipient experience | One-time link + identity verification; no account | Portal-based recipient experience |
| Max file size | Up to 100 GB | Up to 16 TB (configurable) |
| Audit log API to SIEM | REST endpoint with JSON event records | Comprehensive audit + analytics dashboard |
| Time-to-deploy | Marketplace installs in minutes | Platform implementation; days to weeks |

Kiteworks holds the keys (or your organization does, via customer-managed KMS). SendSafely uses a split-key model where neither half is sufficient to decrypt on its own — so neither SendSafely nor your administrators have a path to plaintext.
Kiteworks is a platform you deploy. SendSafely is encryption that drops into the platforms your team already runs — Outlook, Gmail, Zendesk, Salesforce, Intercom, Freshdesk — through native marketplace apps.
Recipients don't sign up for SendSafely. They get a one-time secure link, verify identity (email, SMS, SSO), and decrypt locally.
Every send, recipient, and access event lands in the REST audit log with PACKAGE_EVENT, ADMIN_EVENT, USER_EVENT records — pipe directly to Splunk, Sumo Logic, Datadog, or your SIEM of choice.
Teams moving from Kiteworks to SendSafely typically do it for two reasons: shorter time-to-value (no platform deployment) and an architecture where the file can't be read by anyone but the verified recipient — not even by the platform vendor.
There is no platform to stand up. Encryption arrives through the apps your team already runs, and compliance file exchange covers the regulated traffic. NES Digital Service went live in two weeks on the Developer API.
Every file is encrypted on the sender's device using OpenPGP. SendSafely sees ciphertext only — the decryption key is split so nobody, not even SendSafely, can read the contents on its own.
Audited annually. SendSafely maintains the certifications regulated industries require.
