Scan hub
Security headers, domain MX/SPF/DKIM/DMARC DNS, and phishing URL: three scanners on one page. No sign-up.
Enter a website URL, domain for DNS, or a link to scan. For raw message headers use the email header analyzer. We don't store your inputs.
1. Security Headers Scanner
Check HTTP security headers for a website. Get a grade (A to F) and see which headers are present.
Enter the site you want to scan2. Domain email DNS (MX, SPF, DKIM, DMARC)
Enter your domain to look up mail exchangers, SPF and TXT at the apex, DMARC at _dmarc, and DKIM at common selectors (or specify one). Same tool as the full DNS / email auth page. For a single message, use the email header analyzer.
3. Phishing URL Scanner
Check a URL for common phishing-style indicators. Heuristic only; not a guarantee of safety.
