urlscan.io Alternative — Private URL Scanner

A URL scanner is an online security tool that analyzes websites and links for potential threats. URLScanner.online performs 8 different security checks on any URL, domain, or IP address — including DNS resolution, SSL certificate analysis, HTTP security header inspection, WHOIS domain registration lookup, threat intelligence queries, and multi-viewport screenshots. All scans are performed server-side so your device is never exposed to potentially malicious content.

Simply paste the URL into the search bar above and click Scan. URLScanner.online will automatically check the URL against multiple malware databases including URLhaus, Spamhaus DNS blocklists, SURBL, and Google Safe Browsing. You'll receive a detailed security report with a safety score out of 100 and a clear verdict within seconds.

Yes, URLScanner.online is free. Guests get 1 scan without signing up; free accounts get 3 scans per day. Each scan includes full threat detection, SSL certificate analysis, DNS records, HTTP header inspection, WHOIS data, technology detection, and multi-device screenshots.

Yes. The scanner uses multiple layers of phishing detection: DNS blocklist queries (Spamhaus, SURBL), Google Safe Browsing transparency reports, URLhaus malware database lookups, SSL certificate validation, domain age analysis via WHOIS, and HTTP security header inspection. Newly registered domains with missing security headers and blocklist matches are flagged as potential phishing sites.

Absolutely. All URL scanning is performed on our servers — your browser never connects to the target URL directly. We use isolated headless browsers with sandboxed environments and secure DNS resolution. You can safely scan any suspicious link without exposing your device, network, or personal information to potential threats.

URLScanner.online runs 8 security modules: (1) DNS Resolution — A, AAAA, MX, TXT, NS, SOA, CAA records, (2) SSL/TLS Certificate Analysis — certificate chain, protocol version, cipher suites, expiry, (3) HTTP Security Headers — HSTS, CSP, X-Frame-Options, X-Content-Type-Options, CORS, (4) WHOIS Lookup — domain registration, registrar, creation date, domain age, (5) Threat Detection — URLhaus, Spamhaus, SURBL, Google Safe Browsing, (6) Visual Capture — screenshots at desktop, tablet, and mobile viewports, (7) Security Scoring — weighted score from 0-100, (8) Verdict Classification — safe, suspicious, or malicious.

URLScanner.online combines multiple scanning engines into a single real-time analysis. Unlike basic link checkers that only query one database, we run parallel checks across DNS, SSL, HTTP headers, WHOIS, and multiple threat intelligence sources simultaneously. You get a comprehensive security report with a clear safety score — not just a pass/fail result. The real-time terminal output shows every step of the analysis as it happens.

The URL scanner detects malware distribution sites, phishing pages, domains on DNS blocklists (Spamhaus, SURBL), URLs flagged by Google Safe Browsing, sites with invalid or expired SSL certificates, domains using outdated TLS protocols, websites missing critical security headers (HSTS, CSP), newly registered domains commonly used in attacks, and suspicious redirect chains.
