# Alesian Security Discussions

Alesian Security helps organizations detect and respond to domain-based impersonation and email security threats. Its Lookalike Monitoring service continuously identifies domains that resemble your organization, suppliers, and customers. It confirms domain registration with the authoritative registry, tracks changes in each domain’s digital footprint, and prioritizes threats based on their ability to support attacks; not just how closely their names resemble yours. Security teams can review evidence and request submissions to participating blocklist providers. Alesian’s Sender Security service analyzes DMARC reports to identify email senders, authentication failures, and the changes needed to protect legitimate mail.
