Email Security Tools FAQ
Common questions about Email Security tools, selection guides, pricing, and comparisons.
Email security gateways (SEGs) sit in front of your mail server, filtering emails before delivery using MX record redirection. API-based email security integrates directly with email platforms like Microsoft 365 or Google Workspace via APIs, analyzing emails post-delivery and retroactively removing threats. API-based solutions are better at catching sophisticated phishing and BEC attacks that bypass gateway reputation checks.
