Coral is a healthcare IT company with a platform that directly connects health plans and providers. Coral allows its users to manage the entire referral process from the first call of the patient to the last bill from the provider. Its nationwide system is used by self-insured employers who want bundled offerings and providers who want easy access and management for bundled cases. Coral has 60 remote employees and works with more than 1,000 provider offices across the country.

Coral’s team sends thousands of emails a month outside of its secure platform, some of which may include protected health information (PHI).

Email security presented a roadblock as Coral sought to add new features to its platform. For example, Coral is launching a new feature that creates healthcare vouchers and sends them to patients. However, without encryption, those emails would constitute a HIPAA violation.



Coral’s team first learned about Paubox when a customer sent them an email secured by Paubox. “Ever since we started getting a high volume of customers, we’ve used Paubox to secure everything. It was love at first email footer,” Smith quipped.

Paubox’s seamless, behind-the-scenes email encryption secures every email automatically, with no extra steps for senders or recipients to take. Unlike cumbersome portal-based email encryption solutions, Paubox doesn’t add time or complexity for users. And unlike keyword-based solutions, Paubox doesn’t depend on senders remembering to encrypt specific messages – which can lead to lapses in HIPAA compliance. Paubox Email Suite is HITRUST CSF certified, meeting the industry’s highest email security and HIPAA compliance standards. 

For regular emails sent outside Coral’s platform, the team uses Paubox Email Suite to encrypt every email automatically. “Using Paubox Email Suite has amplified our ability to provide excellent customer service quickly,” Smith said. “For both notifications and our general, day-to-day communications, Paubox is stellar.”



In the past year, Paubox has encrypted nearly 500,000 emails for Coral, including outbound notifications sent through the Coral platform and emails sent directly from 46 Coral team member accounts. “Paubox protects everyone from themselves in a great way. The peace of mind that we get from knowing that everything we send is encrypted frees everyone at Coral up to focus on their work instead of focusing on compliance,” Smith noted.

The time savings – both for Coral’s employees and for its customers – has been tremendous. “Using Paubox doesn’t add anything to our workload. Rather, it reduces the mental burden of focusing on email encryption and HIPAA compliance,” Smith said. “Paubox is a guardian angel protecting the Coral team.”
