What does Email Security mean?

Email security refers to the collective measures used to secure the access and content of an email account or service. It allows an individual or organization to protect the overall access to one or more email addresses/accounts.

An email service provider implements email security to secure subscriber email accounts and data from hackers – at rest and in transit.

Email security gateways secure organizations by preventing malicious emails from reaching their destinations. They generally do this by blocking inbound and outbound emails that contain malicious content – such as malware, spam and phishing attacks. Some email security gateways are also able to detect and block the transmission of confidential data, such as credit card numbers, Social Security numbers, and healthcare records.
