What is email security gateway and what is the purpose of email security gateway in an enterprise? And how does email security gateway work and what are some of the best email security gateway solutions?
A software program called an email security gateway is made to guard email systems against numerous dangers like spam, phishing, malware, viruses, and other email-borne attacks. It is often installed between an organization’s email server and the internet, either on-premises or in the cloud.
All incoming and outgoing emails are intercepted and examined by an email security gateway, which then examines the emails’ content and attachments and employs a number of security measures to guard against potential threats.
And Email security gateway systems often include the following security features:
- Data loss prevention (DLP), which checks outgoing emails for sensitive or private data and stops unintentional or malicious data leaking.
- Secure messaging and email encryption ensure that private emails are sent securely.
- Email archiving and compliance, which records and keeps track of every email correspondence in order to abide by legal and regulatory standards.
- Filters that block suspicious emails and attachments that are spam and malware.
- Advanced threat security that combines machine learning and artificial intelligence to detect and block targeted assaults and zero-day exploits.
