Cyber hygiene in email communication

Cyber hygiene in email communication refers to practices and habits that ensure the safe and secure use of email to protect sensitive data, systems, and personal information from cyber threats.

Email as vector

“Email as the source of an attack decreased from 22.9% in 2022 to 18.1% in 2023,” says Definitive Healthcare. This demonstrates an improvement in implementing cyber hygiene practices in healthcare organizations. However, it also indicates that email can still be used as a vector to deliver a cyberattack.
