SendSafely vs Kiteworks

An end-to-end encrypted alternative to Kiteworks for secure file exchange.

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.

Two products, different jobs.

A side-by-side picture of what Kiteworks is built for, and where SendSafely is built differently.

What Kiteworks does well
  • Comprehensive policy engine for organizations with deep compliance programs
  • On-premises and private-cloud deployment options
  • Industry-specific content security suite covering MFT, secure email, and forms
Where SendSafely is different
  • Split-key architecture instead of admin-managed encryption. 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.
  • Native marketplace installs, not platform deployment. 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.
  • Verified recipients, no Kiteworks-style portal account. Recipients don't sign up for SendSafely. They get a one-time secure link, verify identity (email, SMS, SSO), and decrypt locally.
  • Audit log API direct to SIEM. 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.
Feature comparison

The on-prem trade-off

On-prem buys control. It also buys attack surface.

Why teams choose it

Files stay in infrastructure you control, under your own residency and governance rules. Some regulators and contracts require exactly that.

What it costs

You run an internet-facing file transfer server on your perimeter. Your team patches it, and when a zero-day hits, you wait on Kiteworks for the fix. In September 2026 that meant taking it offline. And a compromised server can expose the files it holds.

The SendSafely approach

Data control comes from the encryption, not the server's location. Files are end-to-end encrypted, and you can store them in an S3 bucket you own. Custody of your data, with no server on your perimeter to defend.

Security record

A breach and a shutdown, on the record.

Every platform ships vulnerabilities. What matters is where the vulnerable code runs, and what an attacker gets when it fails.

Both incidents centered on file transfer servers that customers had to run, expose, and wait on the vendor to fix. SendSafely puts nothing on your perimeter, and because files are end-to-end encrypted, a breach of any single party produces ciphertext, not data.

Why teams choose SendSafely

Four architectural differences that matter.

01

Split-key architecture instead of admin-managed encryption

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.

02

Native marketplace installs, not platform deployment

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.

03

Verified recipients, no Kiteworks-style portal account

Recipients don't sign up for SendSafely. They get a one-time secure link, verify identity (email, SMS, SSO), and decrypt locally.

04

Audit log API direct to SIEM

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.

Who switches

Teams moving from Kiteworks to SendSafely.

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.

  • Financial services firms under SEC 17a-4, FINRA, and supervisory archive requirements
  • Healthcare exchanging PHI with covered entities and business associates
  • Legal practices sending discovery and signed agreements to outside counsel

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.

Enterprise controls

Deep admin control, built in.

Policy, identity, storage, and automation controls for teams that answer to auditors.

Multi-Portal Administration

Run every portal you manage, across subsidiaries, regions, or sandbox and production, from one login. No standing admin accounts, and every action lands in that portal's audit log.

Enterprise

Security Groups

Decide who can send outbound, own Workspaces and Dropzones, or generate API keys. Everyone else stays receive-only, across every integration.

Business · Enterprise

Bring your own bucket

Store encrypted files in an AWS S3 bucket you control, or host in the US, EU, or Sydney. Custody of your data, with nothing to run on your perimeter.

Business · Enterprise

Enforced Workspace expiration

Set default, minimum, and maximum file expiration for every Workspace in the portal, then exempt only the named accounts that need longer.

IP restrictions

Limit registered users to your office or VPN ranges on every path: web, integrations, REST API, and SCIM. Guests are unaffected.

Enterprise

SSO and SCIM

SAML SSO with any SAML 2.0 identity provider. SCIM provisioning for Okta and Entra ID, including admin rights managed from Okta.

Audit Log API

Stream every send, download, and admin action to Splunk, Sentinel, or Chronicle, with long-term retention through S3 export.

Enterprise

Actions

Scan every inbound file with CrowdStrike, OPSWAT, or Sophos, check it with Google Cloud DLP, and quarantine, hold, or archive it automatically.

Enterprise

Native integrations

Encryption inside Outlook, Gmail, Zendesk, Salesforce, Intercom, Freshdesk, and Slack, plus a REST API for everything else.
Audited and compliant

The same controls regulated procurement asks for.

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.

How our architecture works Compliance & certifications
Compliance & certifications
SOC 2 Type 2 HIPAA PCI DSS GDPR CCPA

Full audit trail
Every send, recipient open, identity check, and download is logged with timestamps for compliance reporting.
