DMARC (Domain-based Message Authentication, Reporting and Conformance) is an email authentication standard that protects your business domain from being used by attackers to send fraudulent emails. Hamilton365 implements and manages DMARC for Brisbane businesses as part of email security engagements.
Works with SPF and DKIM to verify that emails claiming to be from your domain were actually sent by you. Tells receiving mail servers what to do with emails that fail authentication, monitor, quarantine, or reject. Provides daily aggregate reports showing all email activity for your domain including attempted spoofing.
Without DMARC, anyone can send email claiming to be from your domain. This enables Business Email Compromise attacks targeting your customers, partners, and suppliers. It also damages your domain's email reputation, causing your legitimate emails to land in spam folders. DMARC at p=reject blocks this entirely.
SPF, publish a list of authorised sending servers for your domain. DKIM, cryptographically sign all outgoing emails. DMARC, set a policy and collect reports. Hamilton365 manages all three steps as part of email security engagements for Brisbane businesses.
