Email Security & Domain Infrastructure
Email Authentication Assessment
A focused review for organizations that know something is wrong—or want to understand their exposure before changing policy.
Request an authentication assessment →What the assessment reviews
Domains and subdomains, sending systems, SPF, DKIM, DMARC, DNS and registrar control, administrative access, and the message paths used by representative senders.
Decisions the assessment supports
A written explanation of material findings, the risks and ownership gaps that matter, a prioritized remediation plan, and a clear distinction between urgent corrections and later hardening.
What is needed to begin
The domain involved, a description of the concern, known email platforms and third-party senders, relevant DMARC reports or message headers, and access only where it is necessary for the agreed review.
Where it can lead
The assessment may stand alone, or it may define a subsequent implementation engagement. Work can be performed directly or alongside an internal IT team, MSP, DNS operator, or software vendor.
Questions the assessment answers
Which domains and systems are sending on the organization’s behalf? Are SPF, DKIM and DMARC authenticating and aligning as expected? Who controls the relevant DNS and administrative access? Which corrections are urgent, and what hardening can follow later?
How the engagement works
Start with the domains, senders and evidence available. Review the authentication and control picture, identify the material issues, and document the decisions that follow from the evidence.
Typical inputs
The domain or domains in scope, known senders and platforms, public DNS information, available DMARC reports or representative headers, and administrative details only where necessary for the agreed review.
What you receive
A written explanation of material findings, a prioritized remediation plan, identified owners and dependencies, and a clear distinction between urgent corrections and later hardening.
Scope boundary
This is defined email-security and domain-infrastructure work—not a substitute for general managed IT, mailbox administration, endpoint management, or an always-on security operations service.
Common situations
A DMARC policy has remained at monitoring mode, a domain has inherited undocumented senders, a new platform needs authorization, or leadership needs a defensible picture of domain-control risk.
Start with the domain.
Share the domain involved, the problem you are seeing, and any known email platforms or senders.
