Microsoft Exchange Online Protection (EOP) is a cloud-based email filtering service that helps protect your organisation against phishing, spoof, spam and malware, and includes features to safeguard your organisation from messaging-policy violations. Phishing protection, spoof, spam and malware prevention. Microsoft Exchange Online Protection can simplify the management of your messaging environment and alleviate many of the burdens that come with maintaining on-premises hardware and software.

An incoming message initially passes through connection filtering, which checks the sender’s reputation and inspects the message for malware. The majority of spam is stopped at this point and deleted by Exchange Online Protection. Messages continue through policy filtering, where messages are evaluated against custom transport rules that you create or enforce from a template. For example, you can have a rule that sends a notification to a manager when mail arrives from a specific sender. Data loss prevention checks also occur at this point, if you have that feature. Next, messages pass through content filtering, where content is checked for terminology or properties common to phishing, spoof and spam.

A message determined to be phishing, spoof or spam by the content filter can be sent to a user’s Junk Email folder or to the quarantine, among other options, based on your settings. After a message passes all of these protection layers successfully, it is delivered to the recipient. Fully scanned for phishing protection, spoof emails, spam and malware destruction.
