ShareFile (now owned by Progress) gives teams a centralized portal for sharing files. SendSafely encrypts files on the sender's device with split-key custody — no portal account required for recipients, no admin path to plaintext, and native integrations inside the tools your team already runs.
A side-by-side picture of what ShareFile 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 | ShareFile |
|---|---|---|
| Client-side encryption (before upload) | Yes — OpenPGP | Server-side at rest; ShareFile manages keys |
| Split-key architecture | Yes — no admin path to plaintext | No — admins can recover content |
| Server on your perimeter to keep files on-premises | None — bring your own S3 bucket instead | Storage Zone Controller (internet-facing Windows server) |
| Recipient experience | One-time link + identity verification, no account | Portal-based with optional guest access |
| Native helpdesk + email plug-ins | Zendesk, Salesforce, Intercom, Freshdesk, Outlook, Gmail | Outlook plug-in, limited helpdesk reach |
| Max file size | Up to 100 GB | Up to 100 GB on most plans |
| HIPAA BAA | On Business and Enterprise | Available on appropriate plans |
| Audit log API | REST endpoint with JSON event records | Activity log with API access |

ShareFile runs in Progress's cloud by default. Teams that need files kept on-premises, under their own residency and governance rules, add a Storage Zone Controller. Some regulators and contracts require exactly that.
You run an internet-facing Windows server on your perimeter, often joined to Active Directory, while logins and permissions still live in ShareFile's cloud. That's two attack surfaces instead of one. When a zero-day hits, you wait on Progress for the fix. In July 2026 that meant powering it down. And a compromised server can expose the files it serves.
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.
Every platform ships vulnerabilities. What matters is where the vulnerable code runs, and what an attacker gets when it fails.
Citing a credible external security threat, Progress told ShareFile customers to shut down their Storage Zone Controller servers. Four days later it confirmed a zero-day (CVE-2026-15724) affecting every 5.x and 6.x release, and shipped patches 5.12.5 and 6.0.2.
watchTowr published an authentication bypass and code execution chain (CVE-2026-2699, CVE-2026-2701) in Storage Zone Controller 5.x, and counted roughly 30,000 internet-facing instances. Progress patched it in 5.12.4.
CISA added CVE-2023-24489, a critical (CVSS 9.8) flaw letting unauthenticated attackers compromise customer-managed StorageZones Controllers, to its Known Exploited Vulnerabilities catalog.
All three hit the same component: a Windows server customers run on their own perimeter to keep files on-premises. SendSafely gives you data control without that attack surface. Files are end-to-end encrypted, and you can back storage with an S3 bucket you own. Read our breakdown of the July shutdown.
ShareFile encrypts at rest with keys ShareFile manages. SendSafely encrypts on the sender's device with OpenPGP — files leave the device already encrypted, and the platform sees ciphertext only.
ShareFile administrators and the service itself can recover or decrypt customer files when needed. With SendSafely, neither half of the decryption key alone can read the file — the architecture prevents an operator-level read.
External counterparties verify identity (email, SMS, SSO) and decrypt the file locally. No portal sign-up, no account license.
Native plug-ins put encrypted attachments where work already happens, instead of asking users to detour to a portal.
Teams moving off ShareFile typically aren't looking for another portal — they want encryption that drops into the tools they already run, with an architecture where the vendor itself can't read customer content.
Recipients never see a portal. Files arrive through Dropzone or land in encrypted storage, and they decrypt in the browser. FreshBooks collects payroll and KYC data this way without any of it touching Zendesk.
Policy, identity, storage, and automation controls for teams that answer to auditors.
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.
Decide who can send outbound, own Workspaces and Dropzones, or generate API keys. Everyone else stays receive-only, across every integration.
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.
Set default, minimum, and maximum file expiration for every Workspace in the portal, then exempt only the named accounts that need longer.
Limit registered users to your office or VPN ranges on every path: web, integrations, REST API, and SCIM. Guests are unaffected.
SAML SSO with any SAML 2.0 identity provider. SCIM provisioning for Okta and Entra ID, including admin rights managed from Okta.
Stream every send, download, and admin action to Splunk, Sentinel, or Chronicle, with long-term retention through S3 export.
Scan every inbound file with CrowdStrike, OPSWAT, or Sophos, check it with Google Cloud DLP, and quarantine, hold, or archive it automatically.
Encryption inside Outlook, Gmail, Zendesk, Salesforce, Intercom, Freshdesk, and Slack, plus a REST API for everything else.
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.
