Why This Matters

Most Organizations Think Email Is Secure. It Isn't.

Email authentication protocols like DMARC, SPF, and DKIM are your first line of defense. But misconfiguration is the norm — not the exception.

Critical

DMARC set to "none"

Monitoring-only mode means spoofed emails still land in inboxes. Your domain can be impersonated with zero resistance.

~80% of domains have DMARC at "none" or no DMARC at all

High

SPF too permissive

Overly broad SPF records allow unauthorized senders to pass validation. Exceeding the 10-lookup limit silently breaks SPF entirely.

SPF lookup overflow is the #1 undetected email config error

Medium

Broken DKIM rotation

Stale or misconfigured DKIM keys weaken message integrity verification. Rotation failures go unnoticed until alignment breaks.

Weak DKIM keys (1024-bit) are vulnerable to brute-force attacks

The result: spoofing, phishing, domain abuse, and failed compliance checks.

These aren't theoretical risks — they're active attack vectors exploited daily against businesses of every size.

What's Included in the Audit

A thorough, external review of your email authentication and DNS configuration — the same view an attacker has.

DMARC Policy & Alignment

Verify policy mode (none/quarantine/reject), alignment settings, aggregate and forensic reporting, and subdomain policies.

Policy modeAlignmentrua/ruf reporting

SPF Record Validation

Detect overly permissive mechanisms, excessive DNS lookups (10-lookup limit), void lookups, and syntax errors.

Lookup depthMechanismsSyntax validation

DKIM Signing Verification

Validate selector configuration, key strength (RSA/Ed25519), signing alignment, and rotation readiness.

Key strengthSelector configAlignment

MTA-STS & TLS-RPT

Assess MTA-STS policy file, DNS record, enforcement mode, and TLS reporting configuration for transport-layer security.

Policy fileEnforcement modeTLS reporting

DNS Hygiene

Identify dangling CNAME records, stale MX entries, misconfigured PTR records, and configuration drift across zones.

Who This Audit Is For

Built for teams that rely on email and need confidence their domain is protected.

Ideal for

Google Workspace users

Ensure Gmail SPF/DKIM defaults are enforced and DMARC is active.

Microsoft 365 users

Validate Exchange Online DNS records and connector authentication.

Cloud-native SMBs

Protect customer-facing domains across multi-cloud environments.

SaaS & tech companies

Prevent domain spoofing that erodes product trust and deliverability.

Compliance-driven orgs

Meet SOC 2, HIPAA, and FedRAMP email authentication requirements.

Not designed for

  • Enterprise on-premises Exchange without cloud DNS
  • Internal penetration testing engagements
  • Parked domains with no active email sending

Unsure? Submit a request and we'll let you know.

Not sure if your email is vulnerable?

That's the point. Most misconfigurations are invisible until they're exploited. The audit takes 30 seconds to request.

Frequently Asked Questions

Is this really free?

Yes. The Email & DNS Security Audit is completely free with no hidden costs. We provide this as a way to demonstrate our expertise and help organizations understand their email security posture. There's no credit card, no trial period, and no obligation.

Do you need access to our systems?

No. The audit is performed externally using only publicly available DNS records — the same information an attacker would see. We never need credentials, admin access, or internal network access. You just provide your domain name.

How long does it take?

You'll receive your audit report within 48 hours of submitting the request. Most reports are delivered within 24 hours. The report includes specific findings, severity ratings, and step-by-step remediation guidance.

Will you try to sell us something?

We'll send you the report and that's it. If you want help implementing the recommendations, we're available — but there's no follow-up sales cadence, no drip campaigns, and no pressure. The report is yours to keep regardless.

What do we get at the end?

A detailed PDF report covering your DMARC, SPF, DKIM, MTA-STS, and TLS-RPT configuration. Each finding includes a severity rating (Critical/High/Medium/Low), a plain-language explanation of the risk, and concrete remediation steps with DNS record examples.

Need help implementing the fixes?

Our engineers can implement every recommendation from your audit — DMARC enforcement, SPF flattening, DKIM rotation, MTA-STS deployment, and ongoing monitoring. Most configurations are production-ready within days.
