Mailvelope vs Trustifi Outbound Shield

Mailvelope adds client-side end-to-end PGP encryption to supported webmail. Its browser add-on works with Gmail, Outlook, WEB.DE, and other webmailers, and can encrypt or decrypt attachments within email, including with PGP/MIME. While composing, it can detect a recipient’s public key; signature mismatches can help identify phishing attempts. Users can export keys, manage multiple keyrings, and use Mailvelope or other key servers. The free private-user offering is independent from Google, but lacks PGP/MIME, Google Workspace integration, and customer service. Mailvelope states that it complies with GDPR and EU privacy laws. Business plans include a 14-day free trial without payment data. Monthly billing costs €3 per user per month; annual billing costs €32.40 per user per year. Paid subscriptions auto-renew and can be cancelled anytime. Business integrations include professional or premium email support options. Mailvelope is available as an extension and through the web.

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.
