ShareFile Email & File Encryption vs StealthMail: Side-by-Side Comparison (2026)

ShareFile Email & File Encryption

Teams managing sensitive file handoffs across mixed email clients need ShareFile Email & File Encryption for its native Outlook and Gmail plugins that encrypt without forcing users into a web portal. SSAE 16 Type II certification and 256-bit encryption covering data in transit and at rest address the PR.DS requirement, while its 100 GB secure sharing ceiling handles most compliance workflows without friction. Skip this if you need granular audit trails and revocation controls; ShareFile encrypts well but treats governance as secondary to ease of use.

StealthMail

Mid-market and enterprise teams handling sensitive email workflows,healthcare, finance, legal,should evaluate StealthMail primarily for its recall and access control capabilities; most competitors encrypt content but can't revoke it post-delivery or prevent forwarding, and StealthMail does both. The hybrid deployment model and user-owned key management (ECC 512+) mean you're not trusting the vendor with your encryption material, which covers the PR.AA and PR.DS functions that matter most for regulated industries. Skip this if your threat model centers on detecting account compromise rather than preventing lateral movement of sensitive emails; StealthMail is a content-control tool, not a mailbox forensics platform.
