FlowCrypt vs Trustifi Outbound Shield

FlowCrypt is an email encryption service that lets users send encrypted messages to OpenPGP users and password-protected messages to other recipients. Recipients can reply securely without installing a plugin. It is offered as a Chrome extension, with other platforms and a mobile application also listed. Gmail and Outlook integration are listed, along with message expiry and password-based recipient verification. The free plan is for fewer than 100 users and lists a 5 MB attachment threshold, while product details say free users can add attachments up to 25 MB. Enterprise supports domains with more than 100 users, and administrators can set domain-wide controls and enforce rules for passphrases, keys, and signing. Enterprise also supports SSO through Google, OIDC providers, and delegated identity providers, and can connect with public key servers, HSMs, and internal systems. Enterprise commercial-use pricing requires contacting FlowCrypt. Its enterprise data processing agreement is described as GDPR-compliant, and enterprise support includes an SLA for availability and response times for fixes and patches.

Trustifi Outbound Shield scans outgoing email against administrator policies and encrypts messages containing sensitive information. Its real-time rules can apply encryption even when a sender has not done so manually, and Trustifi says messages use AES-256-bit end-to-end encryption. Recipients can open encrypted messages with one click without a portal login or password. Senders can recall messages, revoke access to attachments, and prevent forwarding. Tokenization replaces sensitive information with random characters while leaving the rest of an email clear. One-Click Compliance checks messages against more than 10 regulatory guidelines; listed examples include HIPAA, GDPR, CCPA, and PII. Senders can track opens, downloads, and link clicks, while Postmark adds a digital signature described as proof of delivery and reading. A backup system lets users review sent email and send new messages if their email service is down. Integrations include Microsoft Office 365, Exchange on-premise, and Google Workspace. The product is paid, with pricing available on request and no free plan. It is intended for small and mid-size businesses, managed service providers, and regulated industries.
