An email gateway is a type of email server that protects the user's internal email servers. An organization's email gateway is the email server where all incoming or outgoing email goes. This server acts as a gateway to the user organization's email platform. Email gateway does not host incoming email for user email. Instead, it analyzes and scans all incoming emails before sending them to the user's inbox.
The company has no control over which email is directed to its servers. However, when these emails reach their servers, they can take action to bypass them or vice versa. Terms such as email gateway solution, email protection, email filter service, email security gateway, and email gateway encryption are used here.
It is impossible to understand what kind of attacks you will experience in the future regarding emails from hackers and phishing attackers. Using the service of email gateway providers such as https://www.mailsafi.com/ that blocks almost all threats to a business is a huge benefit for the entire business.

Keep all emails encrypted:
This is one of the best security functions that the gateway performs. Even if a hacker accesses the main server, external encryption from this gateway prevents hackers from accessing the emails that are exchanged. Malicious email attacks are numerous and are likely to be successful, so it's always a good idea to take extra precautions in such situations.
Fill in the security hole in the email:
Installing software like antivirus to block external threats is not enough for many reasons. One of the reasons for this is that attackers develop programs that this software can easily circumvent. This is where the email gateway service comes in. Gateways prevent attacks, also through servers, because their structure is different from other email protection software.
