Check the security of your emails and domain for free in one click

Why analyze the DNS and email security of your domain?

Your domain security goes beyond a simple SSL certificate. Many technical parameters — such as SPF, DKIM, DMARC, DNSSEC or TLS-RPT — play an essential role in protecting your communications and your online reputation.

Thanks to our free DNS Security Scanner tool, you can analyze your domain in a few seconds and discover if it is properly protected against the main threats.

👉 Enter your domain name now in the field above and launch a complete analysis.

Email Security: SPF, DKIM and DMARC

These three DNS records determine who can send emails from your domain and how recipient servers should react to suspicious messages.

• SPF (Sender Policy Framework) SPF (Sender Policy Framework) indicates the servers authorized to send emails for your domain.
• DKIM (DomainKeys Identified Mail) DKIM (DomainKeys Identified Mail) signs your messages to prove they have not been modified.
• DMARC (Domain-based Message Authentication, Reporting & Conformance) DMARC (Domain-based Message Authentication, Reporting & Conformance) combines SPF and DKIM to prevent identity spoofing (phishing) and strengthen trust with your customers.

Without these protections, a hacker can easily send fake emails in your company's name, exposing your employees and customers to scams.

👉 Check for free now if your domain has valid SPF, DKIM and DMARC records.

DNS Security: DNSSEC and SSL

• DNSSEC (Domain Name System Security Extensions) DNSSEC (Domain Name System Security Extensions) ensures the integrity of your DNS records and prevents your visitors from being redirected to fake sites.
• Certificat SSL/TLS SSL/TLS Certificate encrypts data exchanged between your site and your users, preventing any interception.

Without DNSSEC or valid SSL, your visitors may be redirected to malicious sites or see a "site not secure" warning.

👉 Test your domain now to verify that your connections and redirects are protected.

Monitoring and Reports: BIMI and TLS-RPT

• BIMI (Brand Indicators for Message Identification) BIMI (Brand Indicators for Message Identification) allows you to display your verified logo in compatible mailboxes, strengthening trust and recognition of your brand.
• TLS-RPT (Transport Layer Security Reporting) TLS-RPT (Transport Layer Security Reporting) automatically informs you of encryption issues so you can intervene before they become critical.

👉 Launch your free audit to find out if your domain is ready for BIMI and TLS-RPT.
