Four Protocols That Protect Your Domain

Email authentication isn't optional anymore. Google, Microsoft, and Yahoo now require DMARC alignment for bulk senders — and cyber insurance carriers verify these controls at underwriting. Here's what each protocol does and why it matters.

DMARC
Domain-based Message Authentication
The policy layer that tells receiving mail servers what to do with email that fails authentication — monitor only (p=none), quarantine to spam (p=quarantine), or reject outright (p=reject). Without p=reject, anyone can spoof your domain.
Critical — Required by carriers
SPF
Sender Policy Framework
A DNS record that lists every server authorized to send email on behalf of your domain. When email arrives from an unlisted server, SPF fails. Missing or overly permissive SPF records are one of the most common domain security gaps.
Critical — Commonly misconfigured
DKIM
DomainKeys Identified Mail
A cryptographic signature added to outgoing email that verifies the message wasn't modified in transit and originated from an authorized source. DKIM must be configured for every service that sends email on your behalf — M365, Google Workspace, CRMs, marketing platforms.
High — Often missing for third-party senders
BIMI
Brand Indicators for Message Identification
Displays your brand logo in supported inboxes (Gmail, Apple Mail, Yahoo) when DMARC, SPF, and DKIM all pass. BIMI requires a verified mark certificate and a DMARC policy of p=quarantine or p=reject. It turns strong email authentication into brand visibility.
Medium — Brand trust signal
Why This Matters for Your Business

Your Domain Is Being Targeted Right Now

Every business domain is a potential attack vector. Without proper email authentication, attackers can impersonate your domain, send phishing emails to your customers and employees, and your business has no way to stop it or even know it's happening.

Business Email Compromise (BEC)

BEC attacks impersonate executives to trick employees into wire transfers or credential theft. Without DMARC enforcement, attackers spoof your CEO's exact email address. The FBI reports over $2.9 billion in annual BEC losses — and most victims had no email authentication in place.

Cyber Insurance Requirements

Major cyber insurance carriers now verify DMARC, SPF, and DKIM during underwriting and at renewal. Missing or misconfigured email authentication can result in denied BEC coverage — the exact scenario you're paying insurance to protect against.

Google & Microsoft Sender Requirements

Since February 2024, Google and Yahoo require DMARC alignment for all bulk senders. Microsoft followed with similar requirements. Organizations without proper authentication see deliverability issues — legitimate emails going to spam or being rejected entirely.

Compliance Framework Requirements

HIPAA, GLBA, CJIS, and CMMC all include requirements for protecting communications and preventing unauthorized access. Email authentication is increasingly cited in audit findings and examiner reports as a required technical control that organizations fail to implement.

Customer & Partner Trust

When attackers successfully spoof your domain to send phishing emails to your customers, the damage goes beyond the immediate attack. Your brand is associated with fraud. Customers lose trust. Even if you weren't breached, your domain was weaponized against the people who trust you.

Securafy Fixes This for You

Implementing DMARC, SPF, DKIM, and BIMI correctly requires identifying every email-sending service, configuring records without breaking existing mail flow, and monitoring authentication results to catch new gaps. Securafy manages email authentication as part of our SECURE-CARE and COMPLY-CARE tiers — properly configured, continuously monitored, and documented for compliance and insurance.

Common Questions

Domain Scanner FAQ

The scanner checks your DMARC, SPF, DKIM, and BIMI records — the four email authentication protocols that prevent spoofing and phishing. DMARC tells receiving mail servers what to do with unauthenticated email. SPF lists which servers are authorized to send mail for your domain. DKIM cryptographically signs emails to verify they weren't tampered with. BIMI displays your brand logo in supported inboxes when all authentication passes.
DMARC prevents email spoofing — attackers impersonating your domain to send phishing emails to your customers, partners, or employees. Without DMARC enforcement (p=reject), anyone can send email that appears to come from your exact domain. Over 90% of cyberattacks start with a phishing email. DMARC is also required by cyber insurance carriers for BEC (Business Email Compromise) coverage, and by Google and Yahoo for bulk email delivery.
A strong domain security score requires all four protocols properly configured: SPF with no syntax errors covering all sending sources, DKIM configured for all services that send email on your behalf, DMARC at p=quarantine (at minimum) or p=reject (ideal), and BIMI for brand visibility. Many businesses fail DMARC entirely or have it set to p=none — monitoring only, with zero protection. Securafy implements and maintains all four protocols as part of our managed security services.
Yes — the domain scanner can check any publicly registered domain. This is useful for checking your own domain, verifying a vendor's email security posture, or checking a competitor's configuration. All DNS-based authentication records (DMARC, SPF, DKIM, BIMI) are publicly visible by design — they're intended to be checked by receiving mail servers worldwide.
If your domain scanner results show missing, misconfigured, or weak authentication records, contact Securafy for a free consultation. Properly implementing DMARC without breaking legitimate email flow requires careful analysis of all your email-sending services — M365, Google Workspace, CRM platforms, marketing tools, billing systems. We implement and maintain email authentication as part of SECURE-CARE and COMPLY-CARE, with ongoing monitoring to catch new gaps as your sending services change.

Your Domain Score Is the Starting Point.
Securafy Fixes What's Broken.

Most businesses discover they have DMARC set to p=none — monitoring without protection — or no authentication at all. Securafy implements and maintains DMARC, SPF, DKIM, and BIMI as part of our managed security services. Prevention-First. Compliance-Ready. Serving businesses nationwide.
