Buying Advice: Prioritize the Recipient Experience

To truly gauge an email encryption solution’s effectiveness, conduct a practical test: send an encrypted message to your most technologically challenged external recipient – perhaps an elderly family member, a vendor using an older email system, or a contact on a generic email service. Carefully track the number of clicks and steps required for them to successfully read the message. If it exceeds two steps, there’s a high probability your internal users will eventually seek workarounds, compromising security.

Begin by fully configuring any baseline encryption capabilities already included in your existing platforms, such as Microsoft Purview or Google Workspace rules. Then, target your investments to address specific gaps: prioritize solutions like Virtru or Paubox for minimizing recipient friction, Proofpoint for robust, gateway-enforced policy, or Echoworx for flexible, white-label delivery. Crucially, automate encryption triggers using DLP and sensitivity labels, removing the burden from individual users. The most critical breach often originates from an email someone simply forgot to protect. For healthcare organizations, a Business Associate Agreement (BAA) from the vendor is non-negotiable, and it’s vital to test the patient-reply path, not just outbound messages. Finally, when evaluating Zix renewals under OpenText, conduct a thorough cost-benefit analysis of their updated roadmap against the complexities of switching providers.
