What is one of the main challenges in email security that an SEG aims to address?

One of the main challenges in email security that a Secure Email Gateway (SEG) aims to address is the high volume of unsolicited emails, commonly referred to as spam. Spam emails are not only a nuisance, but they can also pose significant security risks, as they may contain malicious links, phishing attempts, and other forms of cyber threats. An SEG is designed to filter and block these unwanted messages before they reach the user's inbox, helping to maintain a clean and secure email environment. By effectively managing the influx of unsolicited emails, an SEG protects organizations from potential data breaches, ransomware attacks, and loss of sensitive information, thus bolstering overall email security and user productivity.
