Secure Email Gateway (SEG) is a product packed with engines that work to protect inbound and outbound email from a variety of threats. In the past, Secure Email Gateway was a solution used almost only by large companies, mainly because of its cost and deployment complexity.
But today the situation is quite different. With the evolution of technologies, cost has become more affordable and deployment has become easier, allowing organizations of all sizes to keep their email networks protected. After all, email is the main channel used by criminals to steal data, and promote frauds.
It is important for you to know that there are more basic email protection products on the market that only fight spam and virus. If you ask me, I can say: yes, in general, they are efficient. But not complete. This is where the SEG comes in. It is a solution that goes beyond a simple and primary defense.
Check out some capabilities that a Secure Email Gateway should have:
• A message transfer agent (MTA);
• Anti-virus and anti-malware;
• Network sandboxing;
• Content Disarm and Reconstruction (CDR);
• URL analysis;
• DMARC, DKIM and SPF protocols;
• Customizable Policies and Rules;
• Detection Based on Machine Learning;
• Multiple Deployment Options: Cloud, Hybrid, Virtual and On-Premise.
Some SEG may also offer extra protection with:
• Email encryption;
• Data Loss Prevention (DLP);
• Email continuity and archiving.
Some of these engines and solutions can also be used to enforce protection on platforms such as Office 365, Exchange, G Suite, and Zimbra. The marketing model of a SEG depends on the vendor. In some cases, you can purchase packages with different engines and solutions or just one of them. Our most important tip for choosing a SEG with wisdom is to know more about the characteristics of the product, and to do a Demo. In future posts we will present better some of these engines and capabilities.
