security_dns_recordsDNS records of a domain (A, AAAA, MX, NS, TXT, CNAME, CAA, SOA) resolved live through the public AdGuard DNS JSON resolver (NextDNS as backup). Shows answers as they resolve now, with TTLs; it does not walk the delegation chain or query the authoritative servers directly. Relate…
security_whois_rdapDomain registration facts via RDAP (IANA bootstrap, then the registry's own server): registration, last change and expiry dates, days left, registrar name, status flags, nameservers and DNSSEC delegation flag. Registrant contact data is usually redacted by registries and is not…
security_ssl_cert_chainHTTPS certificate chain and cipher audit for a host (port 443) from Qualys SSL Labs' cached report: grade, number of certificates in the chain, trust store, TLS versions, weak-cipher count, Heartbleed/POODLE/BEAST flags and HSTS. Only reads reports SSL Labs already has, so a hos…
security_crtsh_transparencySubdomain names found in public Certificate Transparency logs for a domain (via CertSpotter): unique host names and wildcard names, issuers, latest issue date and how many listed certificates are still valid. Returns the first page only (up to 100 certificates) and lists at most…
security_ip_geolocation_asnIPv4 or IPv6 address → covering BGP prefix, origin AS number and holder name, whether the prefix is announced, and a coarse country and map point, all from RIPEstat. Location is an estimate (a block-level database), not a street address; the city is often empty. Related tools on…
security_security_headersChecks the live HTTP response headers of a site's home page (one GET, https) for Content-Security-Policy, Strict-Transport-Security, X-Content-Type-Options, X-Frame-Options, Referrer-Policy, Permissions-Policy and Cross-Origin-Opener-Policy. Returns present/missing headers with…
security_dmarc_spf_dkimEmail authentication DNS records for a domain: DMARC policy (p, sp, pct, rua), SPF record and its all-mechanism, and DKIM public keys for a selector you give or for 8 common selectors (revoked keys and CNAME-delegated keys are reported). Reads the published DNS records only; it…
security_urlhaus_malwareChecks whether a host (domain or IP) is known to abuse.ch URLhaus as a malware distribution host: first seen, number of malware URLs, Spamhaus DBL / SURBL status and the latest URLs with status (online/offline), threat type, tags, reporter and URLhaus reference. Price: $0.002 in…
security_phishtank_checkLooks one http or https URL up in the PhishTank phishing database (live checkurl lookup, no key). Returns whether PhishTank has the URL and, if so, its phish id, verification flag and validity. Absence means PhishTank has no record of this exact URL, not that it is safe. Price:…
security_cve_nvd_lookupOne CVE record from the NIST National Vulnerability Database: description, published and last-modified dates, NVD status, primary CVSS score and severity (v4.0, 3.1, 3.0 or 2.0, whichever NVD marks primary first), CWE weakness IDs and up to 5 reference URLs. It does not say whet…
security_tor_exit_nodesChecks an IPv4 address against the Tor Project's bulk exit list (about 1,200 active exit IPs). If it is an exit, adds the relays for that address from Onionoo: nickname, flags, country, first and last seen. Only exit IPs are on the list; a relay's other IPs are not checked. Pric…
security_vpn_proxy_detectorChecks an IPv4 address against the public X4BNet list of commercial VPN provider address ranges (about 11,000 CIDR blocks, refreshed by the list's maintainer). Returns whether the address falls in a listed VPN range and which range. A miss does not prove a direct connection, and…
security_shodan_host_summaryShodan InternetDB summary for an IPv4 address (free, no key): open TCP ports, host names seen, CPE software identifiers, tags and CVE IDs Shodan associates with the host. Data is from Shodan's last scan, so it can be days old; an IP with no data returns empty lists with known=fa…
security_censys_exposureCensys host view for an IPv4 address: the services, ports and protocols Censys has observed on it with their last scan time and detected software, plus autonomous system, location, network owner and reverse DNS, from the Censys Platform API. Related tools on this server, for a d…
security_abuseipdb_checkAbuseIPDB reputation for an IPv4 address over the last 90 days: abuse confidence score (0-100), number of abuse reports, last report date, ISP, usage type and country. Needs a free AbuseIPDB key configured by the operator; reports are crowd-sourced. Price: $0.002 in USDC per suc…
security_grey_noise_noiseGreyNoise Community lookup for an IPv4 address: whether it was seen mass-scanning the internet recently (noise), whether it is a known benign service (riot), its classification (benign, malicious, unknown), name and last-seen date. An address GreyNoise has not seen returns noise…
security_hibp_breach_checkLists the data breaches HaveIBeenPwned has recorded for a domain (breach name, breach date, accounts affected, data types exposed, verified flag). It is the public breach catalogue, not a check of individual email addresses (that needs a paid key and is not offered here). Price:…
security_cisa_known_exploitsCISA's Known Exploited Vulnerabilities catalog (public JSON). With cveId: whether that CVE is on the list, with vendor, product, date added, federal due date, required action and ransomware-use flag. Without it: catalog size, release date and the newest additions (up to 50). Lis…
security_open_port_scannerLists the TCP ports Shodan has seen open on an IPv4 address, from its pre-collected passive scan data (not a live scan: nothing connects to the address now). The record can be days old, and an address with no record returns known=false, which does not prove the ports are closed.…
security_dns_propagationAsks two independent public DNS resolvers (AdGuard DNS and NextDNS) for the same name and record type right now and reports whether they agree, with each answer set and its lowest TTL. It shows cache and geo-DNS differences between resolvers; it is two vantage points, not a worl…
security_reverse_dns_ptrReverse DNS (PTR) names for an IPv4 address, and forward-confirmed reverse DNS: whether each PTR name resolves back (A record) to the same address. Up to 3 PTR names are checked. Many addresses have no PTR record; that is a normal answer. Related tools on this server, for a diff…
security_bgp_prefix_originFor an IPv4 prefix (e.g. 8.8.8.0/24): the origin AS seen announcing it now across RIPE RIS peers, its RPKI status for that origin (valid, invalid or unknown), route objects, visibility, and how many more-specific and less-specific prefixes are seen. An 'invalid' RPKI status is a…
security_dnssec_validatorDNSSEC check for a domain: whether a DS record exists at the parent zone (the domain is signed), and whether two public validating resolvers (AdGuard DNS, NextDNS) return its A answer with the AD (authenticated) flag. It reads the resolvers' verdict; it does not validate the sig…
security_cors_misconfigChecks how a site's home page answers a cross-origin request from a made-up origin: whether it echoes that origin back, sends a wildcard (*), and whether credentials are allowed with it. Echoing an arbitrary origin together with credentials is the risky case. One GET of the home…
security_cookie_securityLists the cookies a site sets on its public home page (one anonymous GET, no login) with their Secure, HttpOnly and SameSite flags, and flags the ones missing a flag. Cookies set later, after login or on other pages, are not seen. Related tools on this server, for a different ne…
security_subdomain_takeoverFor a subdomain: finds its CNAME, matches the target against the public can-i-take-over-xyz fingerprint list (services such as GitHub Pages, S3, Azure, WordPress), checks whether the target still resolves, and fetches the subdomain once to look for the service's 'unclaimed' page…
security_robots_security_txtReads a site's public robots.txt (crawl rules, sitemaps, AI-crawler rules) and security.txt (RFC 9116: contact, expiry, policy), and says whether security.txt is present, current or expired. Missing files are reported as absent, not as errors. Usually answers in a few seconds, u…
security_email_disposableChecks whether an email address's domain (or a domain you give) is on the community disposable and temporary email blocklist (about 9,900 domains). Only the domain is checked, never the mailbox, and a domain missing from the list is not proven to be permanent. Price: $0.002 in U…
security_domain_typosquattingFor a brand domain, generates up to 24 lookalike names (letter omission, doubling and swapping, plus .co/.net/.org/.io swaps) and checks which ones have name servers in DNS right now. Registered-looking names are listed with their name servers. A lookalike with no name servers m…
security_asn_peers_upstreamFor an autonomous system (e.g. AS13335): how many upstream (transit) and downstream neighbours RIPEstat sees in BGP, the top upstreams ranked by 'power' with their IPv4 and IPv6 peer counts, and the top downstreams. Built from RIS route collector paths, so it is an observed view…
security_tls_cipher_enumTLS versions a host accepts (SSL 3, TLS 1.0 and 1.1 flagged as deprecated) and its cipher-suite strength from Qualys SSL Labs' cached report: suite count per protocol, weak suites (RC4, 3DES, NULL, EXPORT, DES, anonymous), and whether forward secrecy is offered. Reads existing r…
security_open_resolver_checkReports whether Shodan's pre-collected passive scan data shows TCP port 53 (DNS) open on an IPv4 address. It is a passive port fact only: it does not send a query, so it cannot say whether the server answers recursively for outside names. Absence means not seen, not closed. Rela…
security_ntp_monlist_auditReports whether Shodan's pre-collected passive scan data shows NTP (port 123) seen open on an IPv4 address. Passive and possibly old; the monlist amplification check itself is not run, so this cannot say whether monlist is enabled. Related tools on this server, for a different n…
security_snmp_exposureReports whether Shodan's pre-collected passive scan data shows SNMP (UDP port 161) seen open on an IPv4 address. Passive and possibly old; no community string is tried, so default or public community access is not tested. Related tools on this server, for a different need: secur…
security_ssh_banner_auditFrom Shodan's pre-collected passive scan data: whether TCP port 22 was seen open on an IPv4 address and any OpenSSH version identified in its software (CPE) list. This is passive and may be days old; it is not a live SSH banner grab or algorithm audit. Related tools on this serv…
security_smb_exposure_testChecks Shodan's passive scan records for TCP port 445 (SMB) on an IPv4 address. Says whether SMB was seen open and when the record was last refreshed by the host data (not a live test). An address with no Shodan record returns seen=false with known=false; that is not proof the p…
security_rdp_exposure_checkChecks Shodan's passive scan records for TCP port 3389 (RDP) on an IPv4 address. Says whether RDP was seen open (not a live test, and the record can be days old). An address with no Shodan record returns seen=false with known=false; that is not proof the port is closed. Related…
security_spameatingmonkeyChecks an IPv4 mail-sending address against the SpamEatingMonkey DNS blocklist (bl.spameatingmonkey.net) through public DNS. A listed address returns its 127.0.0.x return code; an unlisted one returns no record. Listings change often; this is a point-in-time answer. Related tool…
security_barracuda_reputationChecks an IPv4 mail-sending address against the Barracuda Reputation Block List (b.barracudacentral.org) through public DNS. Listed addresses return a 127.0.0.x code; unlisted ones return no record. The list is updated continuously, so this is a point-in-time answer. Domain repu…
security_spamhaus_zenSpamhaus blocklist check through Spamhaus's official Data Query Service: an IPv4 address against ZEN (SBL spam sources, CSS snowshoe, XBL exploited/botnet hosts, DROP hijacked ranges, PBL end-user ranges) or a domain against the Domain Block List (spam, phishing, malware, botnet…
security_surbl_uri_lookupChecks a domain against SURBL's multi-list (multi.surbl.org): whether it appears in spam or phishing URI lists. Listed domains return a 127.0.0.x code. Not listed means not in SURBL's current lists, not that the domain is safe. Price: $0.002 in USDC per successful call, paid wit…
security_openphish_feedChecks a URL or host against the OpenPhish public phishing feed (about 300 currently active phishing URLs, updated continuously). Returns whether the exact URL or any URL on the same host is listed, the feed size and up to 5 example URLs. Not listed does not mean safe; the feed…

security_ipsum_threat_levelChecks an IPv4 address against IPsum, an aggregate of public blocklists: returns the number of source feeds that list it (its level, 1 to 8) and whether it is listed at all. A higher level means more feeds agree. Not listed means none of the aggregated feeds list it. Price: $0.0…
security_cymru_asn_lookupMaps an IPv4 address to its origin AS number, the BGP prefix that covers it, the country, the registry and the allocation date, using Team Cymru's public IP-to-ASN DNS service. Returns no origin when Cymru has no mapping for the address. Related tools on this server, for a diffe…
security_blocklist_deChecks an IPv4 address against the Blocklist.de 'all' list of IPs reported for attacks such as failed logins, SSH and mail abuse (about 24,000 addresses). A hit means it was reported recently; the list keeps only current reports. Price: $0.002 in USDC per successful call, paid w…
security_ciarmy_bad_ipsChecks an IPv4 address against the CI Army (CINS Score) bad-IP list, a collective-intelligence list of addresses that recently showed hostile activity across a sensor network (about 15,000 entries).

security_dkim_key_checkerReads the DKIM public key published at <selector>._domainkey.<domain>: key type, whether it is revoked (empty p=), decoded key size in bytes and a strength hint (about 1024-bit vs 2048-bit RSA), and basic syntax (v=DKIM1). Follows one CNAME, which large providers use. Does not c…
security_bimi_record_auditReads a domain's BIMI record (default._bimi.<domain> TXT): whether it is published, the SVG logo URL (l=) and the certificate URL (a=, a VMC or CMC for mailbox providers). Checks the v=BIMI1 tag and that the URLs are https. It does not download the logo or validate the certifica…
security_mta_sts_validatorChecks MTA-STS for a mail domain: the _mta-sts TXT record (v=STSv1 and id) and the HTTPS policy file (mode enforce, testing or none, the MX patterns and max_age). Reports whether the record and the policy are both present and whether the policy's version is valid. Does not test…
security_dns_caa_recordsLists the CAA (Certification Authority Authorization) records published on a domain: which CAs may issue certificates (issue), wildcard certificates (issuewild) and the incident-report address (iodef). Shows the records on the exact name only; CAA is inherited from parent domain…
security_tls_alpn_detectorReports which newer HTTP protocols a site advertises: HTTP/3 (h3) and older draft or HTTP/2 alternatives in its Alt-Svc response header, and the Alt-Svc max-age. This is what the server announces, not a TLS ALPN negotiation: the fetch this tool makes cannot choose the protocol,…
security_cert_revocation_crlFor a domain's current certificate (taken from public Certificate Transparency data via CertSpotter): reads its CRL Distribution Point, downloads that public CRL, and reports whether the certificate's serial number is on it, plus the CRL's thisUpdate and nextUpdate. OCSP is not…

Flags alg none, symmetric HS algorithms, missing exp and a jku/x5u key reference. It does not verify the signature, because no key is given,…
security_csp_evaluator_auditReads the Content-Security-Policy header of a site's home page and lists weak points: 'unsafe-inline' and 'unsafe-eval' in script sources, bare wildcards, data: or http: script sources, a missing default-src or script-src, and a missing policy altogether. Reports directives. Hea…
security_referrer_policy_auditReads a site's Referrer-Policy header and its <meta name=referrer> tag from the home page, works out the policy a browser would apply, and rates how much of the URL it sends to other sites (strict, moderate or leaky).

security_crossdomain_xml_testReads a site's public crossdomain.xml (Adobe Flash) and clientaccesspolicy.xml (Silverlight) if they exist, lists the origins they allow, and flags wildcard grants ('*'). Old policies are rarely needed now, so a wildcard here mostly means leftovers; absence is the normal case. R…
search_website_content_crawlerReads one public web page and returns its title, description and main text as Markdown (headings, links, lists), plus link counts. Reads only the page you name: no crawling of other pages, no JavaScript rendering, so pages that build their text in the browser may come back short…
