Email security gateways function by scanning incoming and outgoing emails for malicious content, suspicious links, and other indicators of potential threats. They use various techniques such as:
Content Filtering: Analyzing the content of emails to detect spam and phishing attempts. IP Filtering: Blocking emails from known malicious IP addresses. Encryption: Ensuring that the email content is secure during transit. Attachment Scanning: Checking for malicious attachments that could harm the recipient's system. URL Analysis: Verifying the safety of links included in the email content.
