// Overview
Valimail Enforce automates email authentication and DMARC management. It identifies legitimate sending services and helps an organisation move from monitoring to a policy that asks receivers to quarantine or reject unauthenticated mail using its domains. Our Japanese pre-sales team supports sender investigation, SPF and DKIM checks and policy testing. StrategyCore handles licensing, deployment and post-sales technical support within the agreed scope. Receivers decide how to apply DMARC, while lookalike domains, display-name impersonation and compromised accounts require other controls.
