Email, Domain, DMARC and Phishing Security Audit

Reduce spoofing, account takeover and business-email-compromise risk across the technical and human controls protecting trusted communication.

The business problem

Why this assessment matters.

Attackers exploit the trust attached to an organization’s domains and executives. Partial DMARC deployment, weak registrar security, inconsistent mailbox protection and untested payment workflows leave room for convincing impersonation.

Our audit examines the full trust chain: domain ownership, DNS records, email authentication, tenant controls, external exposure, reporting and employee response.

Audit coverage

What we assess.

Final scope reflects your environment, critical systems, risk profile and assurance objective.

SPF, DKIM and DMARC alignment
DMARC reporting and enforcement readiness
DNSSEC, registrar security and domain locking
Lookalike domains and external spoofing exposure
Mailbox authentication and conditional access
Anti-phishing, attachment and URL defenses
Business email compromise workflows
Phishing reporting, simulations and response

Assessment process

How the audit works.

Testing is evidence-led, risk-based and designed to protect business operations.

  1. Inventory sending domains, services and high-risk mail flows
  2. Analyze public DNS and authentication records
  3. Review tenant policies, exceptions and reporting
  4. Test approved spoofing and phishing scenarios safely
  5. Sequence enforcement changes to protect legitimate delivery

Frequently asked questions

Planning your email, domain and phishing assessment.

Will moving DMARC to enforcement block legitimate email?

We analyze authorized senders and reports first, then recommend a staged policy change designed to preserve legitimate delivery.

Can you find services sending mail for our domain?

We combine DNS, DMARC aggregate data and stakeholder discovery to identify known and unexpected senders.

Do you run phishing simulations?

Yes, when authorized. Simulations are designed around agreed learning objectives, privacy limits and escalation procedures.

Can you assess Microsoft 365 or Google Workspace?

Yes. Tenant policies, mailbox protections, authentication and alerting can be included.

Does this include lookalike domains?

Yes. We assess likely impersonation patterns and recommend monitoring, defensive registration or takedown processes based on risk.
