Virtru
enterprise_vendorEmail and data encryption provider offering clientless encrypted email and file sharing for enterprises.
Recipient-controlled access rules that travel with the message and remain enforceable after delivery.
Virtru fits security teams that need encrypted mail behavior tied to identity and policy rather than TLS-only transport protection. Its workflow centers on adding protection at the client or email generation step, which keeps message confidentiality aligned with user and recipient rules. The administration layer supports configuration controls and operational visibility that help teams manage rollouts across groups.
A tradeoff exists when teams require effortless usability for all recipients who do not use the same encryption flow. In practice, organizations often pair Virtru with an internal rollout for most users and an external access experience for third parties. This situation works best when a defined recipient onboarding or access path is acceptable for regulated communications.

How to Choose the Right encrypted email
Encrypted email services in this buyer’s guide cover recipient-controlled confidentiality, encrypted search over protected mailbox content, and encrypted gateway delivery controls across ten providers. The lineup includes Virtru, Proton, Mailfence, StartMail, Posteo, CounterMail, Hushmail, Mimecast, Barracuda Networks, and Egress.
This guide frames the decision around how each provider enforces encrypted delivery after the message leaves the client, how external recipients gain access through portal workflows or compatible encryption, and how security teams administer rollout and governance across domains and sender groups.
Encrypted email services: delivered confidentiality with governed access and policy enforcement
Encrypted email services protect message content by using client-side encryption models, portal-based encrypted delivery for external recipients, or gateway-enforced encryption policies that apply across inbound and outbound flows. Virtru emphasizes recipient-controlled access rules that travel with the message and remain enforceable after delivery, so confidentiality can stay governed beyond transport encryption.
Proton focuses on encrypted message access inside its client and adds encrypted search in its web and mobile apps over protected mailbox content. Mimecast and Barracuda Networks approach confidentiality through gateway policy enforcement, with secure delivery and external recipient access flows tied to administered gateway controls rather than user-only encryption workflows.
Encrypted email capabilities to evaluate across delivery and administration
Encrypted email services only meet security expectations when the confidentiality boundary survives beyond transport encryption and remains enforceable during recipient access. This buyer’s guide compares how Virtru, Proton, Mimecast, and Barracuda Networks handle encrypted delivery after the message leaves the client.
Key differences also show up in how external recipients receive messages through portal workflows or compatible encryption and how much operational control admins get for rollout, governance, and troubleshooting. The feature set below maps those differences provider by provider from Virtru through Egress.
Recipient-scoped encrypted access rules that stay enforceable after delivery
Virtru delivers recipient-controlled access rules designed to remain enforceable after delivery, which supports governed confidentiality beyond transport protection. This matters when security teams need confidentiality controls to persist while messages are accessed days later.
Encrypted mailbox access plus encrypted search for staff and partners
Proton focuses encrypted access inside its client and adds encrypted search in its web and mobile apps over protected mailbox content. This combination is a fit when security teams want staff to find protected content without exposing message bodies to the service.
Gateway-enforced secure delivery controls and external recipient access flows
Mimecast and Barracuda Networks apply policy-driven secure delivery controls at the email gateway so encryption and delivery handling tie into broader email security operations. These models fit teams that want automation hooks in the same administrative surface as other gateway protections.
OpenPGP-centric encrypted workflows for composition and verification
Mailfence and Posteo prioritize OpenPGP workflows that enable encrypted composition and signing for end-to-end message security. This approach fits repeat partner exchanges where key distribution and periodic key handling are already managed.
Protected external recipient access via encrypted delivery portals
StartMail and CounterMail use protected delivery portal workflows to handle external recipients without forcing every recipient to use specialized encryption clients. These portal-first models shift friction from sender setup to recipient access handling and message retrieval.
Managed encrypted delivery for external communications with admin configuration
Egress provides centralized policy enforcement for encrypted delivery across sender groups and uses a managed encrypted message portal experience for recipient access. This is a fit when frequent external communications require consistent admin-managed outcomes.
Choose based on enforcement point, external access model, and admin control depth
A practical selection starts by identifying where encryption enforcement happens relative to the mail client. Virtru and Proton align around client-side confidentiality models, while Mimecast and Barracuda Networks enforce secure delivery at the email gateway.
Next, map how external recipients access encrypted content. StartMail, CounterMail, and Hushmail use encrypted delivery portal style access flows, while Proton and Mailfence depend on compatibility and key handling for external recipients using encrypted clients.
Pick the encryption enforcement point that matches the organization’s operational ownership
If the security team wants recipient-controlled confidentiality rules that stay enforceable after delivery, Virtru is the clearest match. If the security team needs encryption and search over protected mailbox content handled within the Proton client and apps, Proton fits the staff access workflow.
Decide between portal-based external access and compatible encryption for outside recipients
Choose StartMail or CounterMail when encrypted external access should work through a protected delivery portal workflow that avoids requiring specialized recipient client software. Choose Mailfence or Proton when external recipients can participate through compatible encryption paths and correct key setup.
Use gateway policy enforcement only when the gateway is already the security control plane
Select Mimecast when encrypted secure delivery controls are expected to be applied at the email gateway with administered external recipient access flows. Select Barracuda Networks when encrypted message gateway policy enforcement should tie into unified email security operations and investigation logging.
Match OpenPGP workflows to the organization’s key handling maturity
Choose Mailfence or Posteo when security teams want a PGP-first experience with encrypted composition and signing verification inside secure webmail. Choose carefully when external recipient keys are missing or mismatched because that failure mode directly impacts encrypted delivery success.
Validate governance and automation expectations against the provider’s admin tooling surface
If the rollout requires deeper enterprise governance controls and controlled org rollouts, Proton’s provisioning and role controls align with managed onboarding patterns. If automation needs are expected to be lighter and the workflow stays inside a single webmail interface, StartMail’s automation surface is narrower than governance-focused suites.
Who encrypted email services fit best based on workflow and governance requirements
Different encrypted email services fit different enforcement and access workflows. Teams that need governed confidentiality beyond delivery should center selection around recipient-controlled access models and policy enforcement boundaries.
Teams that need staff productivity over protected content should center selection around encrypted search, while teams managing inbound and outbound policy at the gateway should center selection on gateway-enforced encryption and external access handling.
Security teams managing external partner and vendor communications
Virtru fits teams that need recipient-controlled access rules that remain enforceable after delivery, which supports consistent confidentiality when messages outlive transport sessions. Egress also fits teams that send encrypted messages frequently to external recipients and need admin-managed encrypted portal access across sender groups.
IT and security teams with encrypted staff mail search requirements
Proton fits when encrypted search in web and mobile apps is required over protected mailbox content, which keeps message bodies protected while enabling retrieval workflows. This segment also benefits from Proton’s admin provisioning and role controls for controlled org rollouts.
Organizations standardizing on OpenPGP as the encrypted messaging operating model
Mailfence fits when PGP integration inside the mail workflow is required for encrypted composition and verification using secure webmail. Posteo fits when OpenPGP-first encrypted mail exchange is prioritized without gateway-heavy orchestration.
Small security teams that want encrypted webmail workflows with minimal governance overhead
StartMail fits teams that want encrypted message workflows inside a single webmail interface with a protected delivery portal for external recipients. Hushmail fits teams that want an encrypted message portal access flow for protected delivery without full enterprise PKI adoption.
Enterprises with gateway encryption controls as part of a broader email security program
Mimecast and Barracuda Networks fit teams that want encrypted delivery controls applied at the email gateway and administered as part of broader email security operations. These models align with teams that can manage rollout planning for encrypted delivery policy configuration.
Common encrypted email mistakes that break confidentiality outcomes
Encrypted email failures often come from mismatched expectations about where encryption is enforced and how external recipients access protected content. Many issues appear as delivery success with incomplete confidentiality control because policy enforcement or key setup is inconsistent.
Another recurring issue is choosing a workflow that requires encryption client or portal usage discipline that the organization cannot sustain across departments and external stakeholders.
Assuming gateway policy enforcement alone covers external recipients without disciplined portal or encryption access handling
Mimecast can enforce secure delivery at the email gateway, but encrypted delivery policy configuration requires disciplined rollout planning to avoid delivery failures. Barracuda Networks similarly uses policy-driven encryption and delivery handling that needs careful governance to prevent misrouting or inconsistent outcomes.
Breaking external encrypted delivery by ignoring key mismatches in PGP-based workflows
Mailfence encryption can fail for external recipients when keys are missing or mismatched, which blocks end-to-end protection for those recipients. Posteo’s OpenPGP-first workflow also relies on correct key handling for reliable encrypted message exchange.
Selecting client-side encryption but underestimating how external recipients will retrieve content
Proton provides strong encrypted mail access with encrypted search, but external recipients without compatible encryption lose end-to-end protection. Virtru’s governed access rules can also introduce friction if external recipient access paths are not aligned with the organization’s operational model.
Overestimating automation depth when governance needs include directory provisioning and policy orchestration
StartMail’s automation surface is limited for directory provisioning and policy orchestration compared with governance-focused mail security platforms. Hushmail also shows narrower audit logging and retention controls than enterprise email security stacks.
