Not everyone in the organization needs to know how to secure the email service, but anyone who handles patient information must understand email vulnerabilities and recognize when a system is secure enough to transmit sensitive information.

Email protection is vital due to cyber threats like social attacks that focus on organizations via email. For example, phishing emails might trick users into abandoning sensitive information, approving fake bills, or downloading malware that will continue to infect your company network.

Attackers are exploiting businesses’ increased reliance on frequently misconfigured cloud email and general lack of security resources and expertise, and are launching dangerous new email attack campaigns.

Think before you click! Take time to thoroughly evaluate each email you receive before clicking on links, downloading attachments, or interacting with it in any way. For example, ask yourself: Does an order confirmation email you’ve received correspond to a recent purchase you've got made? Do the sender and recipient addresses make sense? Does a suggestion seem too good to be true? If anything seems suspicious, make a phone call to the sender to confirm the legitimacy of the email. 

In a situation like this, it truly is best to be safe than sorry.

There are many Email Security Gateway solutions available. Some are targeted towards enterprise users trying to find granular admin controls and advanced functionality. Some are better suited for smaller businesses looking for an easy-to-use platform with a good price point.
