Check Your Domain's Email Security
Instantly analyze your SPF, DKIM, and DMARC records to protect your domain from email spoofing and phishing attacks. We also scan for domain permutations and lookalike domains that could be used for typosquatting attacks.
Understanding Email Authentication
What is SPF?
Sender Policy Framework (SPF) is a DNS record that specifies which mail servers are authorized to send email on behalf of your domain. Without SPF, anyone can send emails pretending to be from your domain.
What is DKIM?
DomainKeys Identified Mail (DKIM) adds a digital signature to your emails, proving they haven't been tampered with during transit. This cryptographic verification helps recipients trust that emails are genuine.
What is DMARC?
Domain-based Message Authentication (DMARC) tells receiving servers what to do with emails that fail SPF or DKIM checks. It can reject, quarantine, or monitor suspicious emails and send you reports.
Why Monitor Your Domain?
Protect Your Brand
Attackers often register domains similar to yours (typosquatting) to send phishing emails to your customers or employees. We automatically scan for domain permutations including character omissions, transpositions, homoglyphs, and keyboard-adjacent substitutions to detect these threats early.
Improve Deliverability
Properly configured email authentication improves your sender reputation, ensuring your legitimate emails reach inboxes instead of spam folders.
Compliance Requirements
Many industries require email authentication as part of security compliance. DMARC is increasingly mandated for government and financial communications.
Detect Changes
DNS records can be accidentally modified or maliciously changed. Continuous monitoring alerts you to any changes that could compromise your security.
