Free Website Reputation & Blacklist Checker
See whether a domain's IP address is flagged on major security blacklists (DNSBLs) such as Spamhaus, SpamCop, Barracuda and SORBS — and confirm it resolves and serves HTTPS.
By scanning, you confirm you own or have permission to test this domain. Not a substitute for manual penetration testing.
What this website reputation checker checks
How it works
Read-only· reputation feeds + a reachability check- 1We resolve the domain to its IP and query major DNS blacklists (Spamhaus, SpamCop, Barracuda, SORBS).
- 2We cross-check malware/phishing reputation against abuse.ch URLhaus and Google Safe Browsing.
- 3We confirm the domain resolves and serves HTTPS — beyond that single reachability check we send no traffic to the target.
Why it matters
A blacklisted IP means blocked email, lost traffic and broken trust. Catching a reputation hit early protects your deliverability and your visitors.
