Introduction

Email security software can help protect business inboxes from phishing, malware, and account takeovers. This roundup compares four tools, including their threat coverage and deployment options. The best fit depends on your email provider, setup requirements, and security priorities.

Quick comparison

1. Check Point Email Security

Best for: Microsoft 365 or Google Workspace teams seeking broad protection with API deployment.

Check Point Email Security targets phishing, malware, account takeover, and other advanced email threats. It connects to Microsoft 365 or Google Workspace through an API, so deployment does not require MX record changes.

This may suit teams that want added protection without routing mail through a different gateway. API deployment without MX changes is a notable feature, but check the vendor’s setup requirements to see what the connection involves for your environment.

2. Barracuda Email Protection

Best for: Microsoft 365 or Google Workspace users who want protection and response across the email lifecycle.

Barracuda Email Protection connects to Microsoft 365 or Google Workspace using an API. Its stated capabilities include email threat protection, account takeover detection, and automated remediation.

Automated remediation may appeal to teams that want response actions as part of their email security approach, rather than detection alone. Before choosing it, ask Barracuda which actions are available for your provider and configuration.

3. Proofpoint Core Email Protection

Best for: Organizations prioritizing detection of phishing and business email compromise.

Proofpoint Core Email Protection uses behavioral AI and threat intelligence to identify email threats, including phishing and business email compromise. It looks at suspicious behavior as well as known threat patterns.

That combination may suit organizations focused on targeted or deceptive messages. Ask Proofpoint for current product details, provider compatibility, and the deployment options available to your organization.

4. Cloudflare Email Security

Best for: Teams comparing multiple ways to connect email security to Outlook or Gmail.

Cloudflare Email Security analyzes incoming email for phishing, malware, business email compromise, vendor email fraud, and spam. It offers API, BCC/journaling, and MX/inline integration options for connecting to providers such as Outlook and Gmail.

The range of integration methods is a key feature. Each option can affect setup differently, so review Cloudflare’s requirements and choose the approach that fits your mail environment before implementation.
