What are inbound vs outbound email threats?

Inbound threats target your users through email they receive: phishing, malware attachments, malicious links, and social engineering. Protection focuses on filtering dangerous messages before they reach recipients.

Outbound threats originate from your infrastructure: compromised accounts sending spam, infected machines distributing malware, and data exfiltration through email. Protection focuses on detecting and blocking malicious sends from your systems.

Both directions matter. Inbound protection shields your organization from external attacks. Outbound protection prevents your organization from becoming an attack source, protecting reputation and preventing harm to others. Comprehensive security addresses both vectors.
