Healthcare Email Security Vendors

We have compiled a list of healthcare email security vendors that provide cloud-delivered email security solutions capable of detecting and blocking threats such as phishing, malware, botnets, and ransomware, and have advanced threat detection capabilities for detecting zero-day malware threats.

Email Security in Healthcare

The healthcare industry is extensively targeted by threat actors seeking sensitive personal and protected health information, proprietary data, and access to healthcare networks for conducting ransomware attacks. Diverse tactics are used to gain a foothold in networks, including brute force attacks to guess weak credentials and the exploitation of vulnerabilities in software and operating systems; however, email is the number one attack vector. More than 90% of cyberattacks start with phishing emails.

Most email security solutions are effective at blocking spam email and known malware threats, but email-based cyberattacks have become more sophisticated. Email security solutions with advanced threat detection capabilities are now required to block these attacks.
