- SEG:
- Security Email Gateway
Secure Email Gateways (SEGs) are an email security solution that sits inline on emails’ path from the public Internet to the corporate email server. This position allows it to inspect email for malicious content before it reaches corporate systems. However, the design of the SEG makes it less suited to protecting modern cloud-based email solutions.
