Email is the backbone of business communication for most organizations, and being an indispensable communication medium, it is highly vulnerable to cyberattacks. Today, email security challenges have become increasingly sophisticated and threatening to businesses. The drastically rising number of phishing and ransomware attacks pose challenges that can severely dent an organization’s brand image and reputation. With a massive shift to remote work recently, email security is now more critical than ever (and potentially more complex). A secure email gateway is imperative to protect businesses from email-borne threats, including malware, ransomware, and phishing links while helping ensure safe and secure information transmission.
What is a secure email gateway?
A secure email gateway monitors inbound and outbound emails to filter and block malicious content and prevent email-based threats from reaching a mail server. It helps protect the business email environment against phishing attacks, malware, spam, and ransomware—to prevent the loss of confidential data and business-critical information.
Employing a secure email gateway helps managed services providers (MSPs) and IT teams safeguard businesses from malicious email attacks. Additionally, enterprises leverage various benefits by implementing a robust secure email gateway solution, such as:
- Improved regulatory compliance: A secure email gateway provides encryption and email archiving capabilities to help ensure data security and drive adherence to compliance.
- Business continuity: A comprehensive, secure email gateway with a web-based console allows continuous email operations, even when the primary email server is down, to avoid operational disruption.
- Better employee security: Employees are vulnerable to email security threats, like spam and phishing attacks. A fortified email gateway provides employees with frontline defense and protects them against business email compromise and account takeovers.
Now that we understand the importance of a secure email gateway for organizations (of all sizes across industries) to protect their business against spam, hackers, and viruses, let’s look at the list of top secure email gateways.
