Review business email systems for secure mail flow, authentication, anti-phishing defenses, and operational readiness.
Mail flow
Review sending and receiving domains, connectors, gateways, routing rules, and message tracing or diagnostic capabilities available in the selected email platform.
Authentication
Validate SPF, DKIM, DMARC, strong authentication, and exposure from outdated protocols or insecure relay paths.
Routing and policy rules
Identify outdated, duplicated, overly broad, or conflicting routing, forwarding, and mail security rules.
Mailbox protection
Assess anti-phishing, impersonation protection, URL filtering, attachment scanning, and additional safeguards for high-risk users.
Operations
Confirm monitoring, escalation, documentation, and ownership for incidents, changes, and recurring email problems.
