If someone can send an email that looks like it came from your domain, your clients and vendors have no way to know it is fake. This is called email spoofing and it happens to small businesses every day. DMARC, SPF, and DKIM are the three records that stop it. Most small businesses either do not have them configured at all or have them set to monitor only, which means they are watching the problem happen without actually blocking anything.
Talk About Your EnvironmentDMARC tells receiving mail servers what to do when someone tries to send email pretending to be from your domain. SPF defines which servers are allowed to send on your behalf. DKIM adds a cryptographic signature that proves the message was not tampered with. All three working together at enforcement level means spoofed email gets rejected before it reaches anyone. We take organizations from no email authentication to DMARC at p=reject with full SPF and DKIM alignment. That is the only posture that actually protects your domain.
We start by reviewing your current DNS records and identifying everything that needs to change. We implement SPF cleanup, DKIM signing, and DMARC in reporting mode so you can see what is sending mail on your behalf before enforcement goes live. Once the traffic is clean we move you to p=reject. The engagement does not close until enforcement is verified and working.
Any organization running Microsoft 365 or Google Workspace that has never had email authentication reviewed. Businesses that have been told their emails are landing in spam folders. Organizations that recently discovered someone was impersonating their domain.
