Operating Context

Mailbox protection across identity, delivery and user behavior.

Email security combines authentication records, filtering, mailbox hardening, reporting, migration planning and incident response so protection is not limited to a spam filter.

The final scope, response model, commercial terms and exclusions are confirmed in the approved proposal, service agreement or statement of work.
