A common misconception about HIPAA compliance is around the concept of email portals. Some people believe the only way to have HIPAA compliant email is to utilize email portals.
This post will explain what email portals are, how they came about, and why they are not required for HIPAA compliant email.
The method of forcing users to view secure email via a browser is known as an email portal.
As a practical matter, the user experience for recipients of email portals is at best cumbersome, at worst awful.
For example, here's the actual workflow being used by Microsoft 365 for its encrypted email solution, Microsoft Purview Message Encryption.
In this step, the recipient gets an email asking them to click on the link, Read the message.
The link then opens in a browser, which is encrypted via a secure HTTPS connection. Now the user needs to click another link, Sign in with a One-time passcode.
This is the email that gets sent with the one-time passcode. Can you imagine doing all of this on a smartphone?
Now that the user has pasted the passcode into the text box, the next step is clicking Continue.
After six steps and in this case 77 seconds, the recipient can finally read the secure email.
Ouch. A painful experience.
Email portals came about because the protocol governing email, Simple Mail Transfer Protocol, was not built with security and encryption as a top priority.
Instead, the top priority of SMTP is message delivery. In other words, if an email is sent with TLS encryption by the sender, yet the recipient's mail system is not setup to accept an encrypted connection, the message automatically downgrades to no encryption. In other words, it gets sent in cleartext across the internet, even though the sender has intended for it to be encrypted in transit.
In slightly technical terms, this process is known as opportunistic encryption.
As a workaround, companies like Microsoft decided long ago to design a secure email system that instead redirected users to an encrypted browser connection using HTTPS encryption.
In a browser like Chrome or Firefox, any URL starting with http:// is not encrypted and those starting with https:// are encrypted.
It's easy to configure an email portal to always use HTTPS. This ensures encryption is always used to view the contents of an email, regardless of what the recipient's mail system is. In this regard, it's an effective method to maintain encryption and HIPAA compliance.
The question is however, are email portals the only way to achieve HIPAA compliance for email?
In a nutshell, the answer is no.
Here's why you don't need email portals to be HIPAA compliant:
