Check a whole website's security in seconds: the TLS certificate (trusted by browsers, expiry, the names it covers), the security headers (HSTS, Content-Security-Policy, framing, nosniff, referrer and permissions policies), cookie flags, whether http:// moves to https://, the domain's mail records (SPF, DMARC, MX), whether the domain or the addresses serving it are on phishing or abuse lists, and the bot protection the home page loads. Returns a 0-100 score, a grade from A to F, every finding with the exact fix to apply (header lines, DNS records, server settings), and what passed. Reads only what any visitor sees. Free, no key: 20 fresh checks an hour per address, 300 per account with a free key; a site checked in the last ten minutes costs nothing.

Fraud intelligence for any IPv4 or IPv6 address: a 0-100 fraud score, risk band, and whether it is a VPN, proxy, Tor node, relay, datacenter host or mobile connection. Also returns the owning network (ASN, ISP, organisation), geolocation, reverse DNS, abuse history and how much of its /24 subnet is flagged. Free, no key. Use it before trusting a signup, a checkout or an API caller.

Check an email address before you let it create an account: whether it is disposable or throwaway, a role address, on a community blacklist, or tied to a domain that hands out temporary mailboxes. Free, no key.

Reputation for a domain: whether it hands out disposable mailboxes and whether it appears in the phishing dataset, with a risk level. One unauthenticated lookup, no key.

The community abuse reports filed against an IP: what it was reported for, when, and by how many distinct reporters. Use it when you want the evidence behind a score rather than the score alone.
