How to Choose the Right email encrypting software
Email encrypting software choices in this buyer’s guide range from Virtru and Proofpoint to Mimecast and Egress, with each platform enforcing encryption using a different control point in the mail flow. Virtru focuses on secure envelope packaging that keeps recipient access rules intact after delivery, while Proofpoint runs centralized encrypted delivery with a managed decryption workflow.
Mimecast, Barracuda, and LuxSci emphasize gateway-driven policy decisions for outbound encryption, so the same encryption behavior applies across many mail users. Posteo and Soverin skew toward recipient-side experience through webmail or portal access, and Citrix ShareFile prioritizes encrypted attachment sharing instead of full mailbody encryption.
Email encrypting software that enforces encrypted delivery and governed recipient access
Email encrypting software applies encryption controls to messages before delivery, after delivery, or at the gateway, depending on whether enforcement lives in the sender client, the inbound or outbound mail stream, or the encrypted message workflow. Virtru’s secure envelope packaging enforces policy-controlled recipient access so encryption rules persist beyond the initial send event.
Proofpoint uses a centralized encrypted delivery model that replaces end-user key handling with a controlled decryption workflow, which shifts key and access complexity away from recipients. Across the top tools, policy-based encryption behavior, governed recipient access, and gateway enforcement determine whether encryption stays consistent when mail routing, recipient capabilities, or user endpoints vary.
Encryption enforcement point, governed access, and automation surfaces
Email encrypting software is defined by where encryption decisions and recipient access enforcement happen in the mail flow. Virtru secures delivery with policy-controlled recipient access that persists after delivery, while Proofpoint centralizes a controlled decryption workflow that removes end-user key handling from recipients.
Governed recipient access that survives delivery
Virtru packages messages into a secure envelope so recipient access rules remain intact after delivery using policy-controlled recipient access with expiring and permission limits. This makes Virtru a fit when encryption rules must persist beyond the initial send event.
Centralized controlled decryption workflow
Proofpoint uses a controlled decryption workflow for recipient delivery so the platform manages the decryption experience instead of expecting recipients to manage keys. This supports centralized auditing and managed recipient access for compliance teams.
Gateway policy enforcement for outbound mail flows

Portal-based recipient access for message viewing
Soverin provides portal-based recipient access tied to its secure delivery workflow so encrypted viewing works through a portal flow without client plug-ins. Citrix ShareFile also uses a recipient portal with expiring and permission controls, but it prioritizes secure file sharing for email-delivered attachments over full mailbody encryption.
Pick the enforcement and access model that matches mail operations
Start by choosing the control point that can enforce encryption consistently across your actual email routing paths. Virtru and Proofpoint focus on encrypted delivery workflows, while Mimecast, Barracuda, LuxSci, and Egress focus on gateway-driven outbound encryption decisions.
Choose delivery-workflow enforcement when key handling must be removed from recipients
Select Proofpoint when encryption delivery requires a centralized managed experience using a controlled decryption workflow instead of pushing key management onto recipients. Choose Virtru when the enforcement goal is policy-controlled recipient access that remains effective after delivery via secure envelope packaging.
Choose gateway policy enforcement when outbound routing must stay consistent across many senders
Choose Mimecast when outbound mail flows need gateway-enforced encryption driven by outbound handling policies plus governed certificate workflows. Choose Barracuda when centralized mail flow rules drive gateway encryption decisions and delivery outcome visibility for admin-controlled enforcement across outbound flows.
Choose admin-console gateway enforcement when sender clients cannot be relied on
Pick Egress when encryption behavior must be governed from a central admin console so outbound policy rules apply consistently without per-message steps by senders. Pick LuxSci when policy-based gateway encryption must apply across mixed recipient capability scenarios without requiring sender client setup.
Choose recipient portal workflows when endpoint plug-ins must be avoided
Select Soverin when secure delivery should use a portal-based recipient access flow that avoids endpoint plug-ins for encrypted viewing. Select Citrix ShareFile only when secure attachment sharing is the priority, because it is not designed for full mailbody encryption coverage.
Choose webmail-integrated PGP when lightweight encrypted sending matters more than enterprise governance
Pick Posteo when users need direct encrypted composition and recipient encryption in a webmail workflow with PGP key management. Accept the lack of centralized API-driven policy encryption and automated key provisioning that enterprise admins typically need.
Confirm that policy flexibility matches admin capacity for ongoing operations
If advanced policy scenarios are expected, Virtru’s expiring and permission policies require governance discipline and rollout across senders. If delivery consistency must be preserved across mail flows, Proofpoint workflow consistency depends on standardized Proofpoint-managed mail flow and careful policy design to avoid delivery friction.
Who should buy email encrypting software based on enforcement needs
Enterprises that must enforce encryption and access controls across many users should focus on gateway-driven enforcement or governed encrypted delivery workflows. Teams that want to keep recipients away from key management should prioritize Proofpoint and Virtru models.

Common buying pitfalls that break encryption guarantees
Many failed encryption rollouts come from choosing a control point that does not match how mail is routed and how recipients actually access protected content. Another recurring issue is assuming policy flexibility is free operationally when governance and workflow consistency must be maintained over time.
Selecting a product that enforces encryption at the sender client when the organization cannot standardize endpoint setup
Posteo emphasizes webmail-integrated PGP key management for user encrypted sending, which avoids gateway administration but does not provide centralized API-based policy encryption or automated key provisioning. Gateway-first tools like Egress and LuxSci apply outbound encryption behavior from admin-controlled rules instead of relying on sender client setup.
Assuming recipient access control works the same after delivery
Virtru’s secure envelope packaging is designed for policy-controlled recipient access that persists after delivery. Proofpoint and other controlled decryption workflows focus on delivery and decryption experience, so recipient access lifecycles need to be mapped to the workflow design.
Overlooking gateway workflow dependencies for consistent encryption enforcement
Proofpoint operational consistency depends on standardized Proofpoint-managed mail flow and careful policy design to avoid delivery friction. Barracuda also relies on correct mail flow policy configuration so encryption enforcement scope and outcomes remain predictable.
Choosing portal-based tools when full mailbody encryption coverage is a requirement
Citrix ShareFile supports recipient portal expiration and permission controls for secure sharing, but it is not designed for full mailbody PGP/MIME or S/MIME encryption coverage. Soverin supports portal-based recipient access for secure encrypted viewing, but advanced API-based extensibility is limited compared with gateway-first competitors.
