Why Secure Email (Powered by Paubox)

Cloud Maven's Secure Email is a Salesforce-native application that lets teams send and receive encrypted email without leaving Salesforce. Standard Salesforce email isn't secure by nature — it isn't encrypted in transit or at rest by default. Secure Email closes that gap using Paubox's HIPAA-compliant encryption engine.

Looking for feature details, security specs, or how message delivery actually works? See the Features page, the Product Overview, or the High-Level Workflow & Paubox Encryption Architecture page. This page focuses specifically on why customers choose Paubox and how it compares to Microsoft's encrypted email.


Why Customers Choose Paubox

Organizations choose Cloud Maven's Secure Email, powered by Paubox, for two main reasons:

  1. Reducing risk in transit. Paubox encrypts every message by default — eliminating the risk of sensitive data being intercepted or transmitted in plain text (for example, in a man-in-the-middle attack).

  2. Keeping messages readable for recipients. Most encryption solutions force a trade-off: better security, worse usability, since recipients have to navigate portals, plugins, or extra logins. Paubox avoids that trade-off — it's HITRUST CSF Certified, one of the few email encryption solutions on the market with that certification, while still delivering messages with zero extra steps for the vast majority of recipients.

  3. Maintaining complete conversation context in Salesforce. Every secure email and reply automatically threads back to the originating record—cases, accounts, or contacts or any custom object—eliminating context-switching and creating an unbreakable audit trail without manual logging or external systems.

  4. Automating compliance-heavy workflows. Trigger encrypted emails automatically through Salesforce Flows and Apex triggers for approvals, case notifications, document requests, and onboarding—no manual intervention required, encryption built in by default.

How Paubox Compares to Microsoft's Encrypted Email

Microsoft typically attempts to deliver email using TLS. If the recipient's mail server supports TLS 1.2 or higher, delivery is secure; if not, Microsoft may fall back to an older, less secure protocol — or, if TLS is explicitly required, fail to deliver the message at all. That failure can also happen due to a temporary server misconfiguration on the recipient's side, not just a genuine lack of TLS support. Organizations relying on Microsoft for HIPAA-compliant delivery also need to separately confirm the resulting configuration is covered under Microsoft's BAA.

Paubox handles the no-TLS case differently: instead of failing or downgrading, it delivers a secure link to the Paubox Secure Message Center, preserving HIPAA compliance even when a recipient's server can't establish a TLS 1.2+ connection.

This is a general comparison — Microsoft's actual behavior depends on the specific configuration in place. For a deeper comparison across all available secure email options, see Secure Email Options & Recommendations, or read Paubox's own writeup: Paubox vs. Office 365 Encrypted Email.
