SPF DKIM DMARC setup
Design and implement email authentication that reflects your email provider, marketing tools, forms, billing system, help desk, and any other authorized sender.
Email security hardening
Make it harder to impersonate your business.
A trusted email domain does more than reach the inbox. It makes it clearer which messages are genuinely yours—and gives receiving servers instructions for handling the rest.
The goal
Protect the identity behind your email.
Email spoofing happens when an attacker sends mail that appears to come from your domain. Good SPF, DKIM, and DMARC setup gives mailbox providers the information they need to tell legitimate messages from fakes.
Hardening is not simply adding three records. The records must account for the systems your business actually uses, line up with the visible sender identity, and move toward an enforcement policy without breaking legitimate mail.
Security work, in context
Setup that respects your real sending environment.
DMARC reporting & rollout
Use reports to see who is sending as your domain, resolve legitimate sources, and plan a safe progression from monitoring to quarantine or reject.
Access & account safeguards
Review the high-value controls around your email platform: privileged access, forwarding, delegation, recovery paths, and configuration ownership.
A safer DMARC path
Enforcement is a process, not a switch.
01 / Discover
Observe your sources
Start with reporting and an accurate map of the tools that send email for your domain.
02 / Align
Fix authorized senders
Correct SPF, DKIM, and identity alignment for the mail that should be there.
03 / Tighten
Apply a clear policy
Move carefully beyond monitoring once the legitimate traffic is understood.
04 / Maintain
Review changes
New platforms and acquisitions can create drift, so the setup needs an owner.
What this is not
Email security is one part of a wider security posture.
This service focuses on the email identity and operational controls most connected to authentication, spoofing, and trusted sending. If a broader cybersecurity assessment is needed, I can discuss a focused secondary engagement or help clarify the right next step.
