Best Secure Email Gateway Software for BackBox

Proofpoint Email Protection solutions—deployed as a cloud service or on-premises—protect against malware and threats that don't involve malware, including impostor email, or business email compromise (BEC). Granular email filtering controls spam, bulk "graymail" and another unwanted email. And continuity capabilities keep email communications flowing when your email server fails. Proofpoint Email Protection is the industry-leading email gateway, which can be deployed as a cloud service or on premises. It catches both known and unknown threats that others miss. Powered by NexusAI, our advanced machine learning technology, Email Protection accurately classifies various types of email. And it detects and blocks threats that don’t involve malicious payload, such as impostor email—also known as business email compromise (BEC)—using our Advanced BEC Defense. You can also automatically tag suspicious email to help raise user awareness. And you can track down any email in seconds.

Clearswift Secure Email Gateway (SEG) provides uniquely powerful protection of an organization's email data against inbound cyber-attacks and outbound data loss prevention. As the number one method of communication for most organizations, email has become one of the top sources for cybercriminals to infiltrate your systems and take hold of your critical data. Our Secure Email Gateway protects against known and unknown malware but also advanced threats including phishing. IT teams need to ensure that information being shared across email both in and out of the organization is not only secure, but appropriate and compliant. Clearswift’s unparalleled level of inspection and granular policy controls apply the optimal security treatment to your emails in real time so your communications remain safe and flowing, and business disruptions are minimized.

Email remains the most critical communication tool for business. Unfortunately, that also makes email the top threat vector, with the volume and sophistication of attacks ever-increasing. At the same time, customers are increasingly moving to cloud email providers, like Microsoft 365 and Google G-Suite, and are struggling to secure their email traffic. The built-in, native security tools available in these platforms are by themselves insufficient to guard against attacks, protect valuable data, and ensure compliance objectives are met. FortiMail, Fortinet’s secure email gateway solution, provides a comprehensive, multi-layered approach to address all inbound and outbound email traffic. Fortinet is a trusted vendor and offers the industry’s broadest portfolio of security solutions,—including identity management, advanced threat/zero-day protections and security-driven networking—with its Security Fabric.
