What Are Email Gateways?
Even if you are coming from a non-technical background, you might have some idea about what is email and how it works. We know that it requires a client, a server, and a network. So, an email gateway is basically a kind of email server that safeguards the internal email server of a user or an organization. You can imagine it like a gateway through which every outgoing and incoming email goes through. It is implemented to keep unwanted emails at bay and ensure that only good emails are sent and received.
Unwanted emails include phishing attacks, malware, spam, or fraudulent messages. Email gateways not only prevent harmful emails from coming into your system but also encrypt your confidential data when it leaves your organization. Secure email gateway options automatically ensure encryption of emails containing sensitive information when they leave your system.
