Email security should be a top priority for your company. Email is the number one target used by hackers to get access to your company’s private data, and email attacks such as phishing and business email compromise are on the rise. Your first line of defense should be an Email Security Solution, a platform that guards your emails against hackers, spam and viruses.
There are many Email Security Gateway solutions available. Some are targeted toward enterprise users looking for granular admin controls and advanced functionality. Some are better suited for smaller businesses looking for an easy-to-use platform with a good price point.
To help you find the right solution, Expert Insights has identified some of the top email security solutions. These are deployed using different cloud-based technologies including Secure Email Gateway (SEG), API integration and Mail Flow Redirection. We’ll take you through their key features, their functionality and how well they work.

What Is Email Security?
Email security solutions prevent malicious emails from being delivered to, circulating within or being sent from your email network. Email security is a broad umbrella term, which can be used to refer to multiple technologies, software solutions and frameworks designed to protect email networks.
It is important for all organizations to have an effective email security framework in place to protect users, customers and partners from sophisticated email threats such as spam, malware, phishing and business email compromise. Email security is also important to ensure and demonstrate compliance with data security regulations.
What Are Email Security Gateways And What Are The Key Features?
Email security gateways are designed to act as a shield for your email network, blocking inbound malicious email content from reaching user inboxes, and preventing outbound malicious email content from being sent.
Many email security gateways use a mixture of email content scanning, domain reputation scanning, URL scanning and attachment sandboxing tools to make a deterministic assessment of an incoming email message. If the message is deemed malicious, it is blocked; if it is deemed safe, it is delivered.
Admins should have the ability to configure policies which govern how this filtering works. They may wish to block emails from certain domains or allow emails from known safe senders. In addition, email security gateways should provide detailed reporting to help organizations track incoming email threats.
What Is Cloud Email Security?
Modern email security gateways are often entirely cloud-based but can also be deployed on-premises or as hybrid solutions. Deployment should be straightforward, especially with cloud-based email systems such as Microsoft 365 or Google Workspace.
This list also includes cloud-based email security solutions, that are not traditional gateways, but sit in a category Gartner terms “Cloud Email Security Supplements” (CESS). These vendors are often fully cloud native, and integrate with O365 and Google via API integrations, with no changes required to MX records.
The benefit of these solutions is that they can provide greater protection inside the email network than SEGs, which typically provide enhanced protection to the email network at its border. This means cloud email security solutions can more effectively spot signs of phishing and account compromise.
Our recommendation is that businesses needing strong email security should consider implementing multi-layered email protection, pairing a gateway with some form of inbox-based email security solution.
