Enter any domain and instantly see your DMARC, SPF, DKIM, and BIMI configuration — the four email authentication protocols that prevent attackers from spoofing your domain and sending phishing emails in your name. 90% of cyberattacks start with email. Your domain score tells you how exposed you are.
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.
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.
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.
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.
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.
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.
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.
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.
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.
