Lockbin vs Trustifi Outbound Shield

Lockbin is a web application for sending private email messages and files. Recipients can open a message using a unique URL and password; passwordless secure links are also available for known recipients. Messages use TLS in transit and FIPS 140-2 verified AES-256 encryption at rest. Decryption keys are held by the sender and recipient rather than stored in plaintext on Lockbin servers. It works in Chrome, Firefox, Safari, or Edge without a download or installation, and is listed for Linux, macOS, web, and Windows. Lockbin works alongside Google Workspace and Microsoft 365 without a plugin or extension. Premium users can create file-drop links or secure forms to receive files without requiring an account or password. The free plan covers one user, 25 MB attachments, and six months of inbox storage; the site also advertises 10 free messages with no credit card required. Premium costs $10 per user per month. Uncollected messages are destroyed after six months, and read files not marked for deletion are removed within 24 hours.

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.
