Free Web Security & DNS Audit Tools

Use free web security and DNS audit tools for headers, TLS, DNS, DMARC, CORS, APIs, technologies, WHOIS, and subdomain checks.

Free Web Security & DNS Audit Tools is part of the PentestHint VAPT Tools platform. The tool is designed for quick reconnaissance, evidence collection, and security posture review. Use it to collect observable security data, validate common misconfigurations, and decide when a deeper VAPT engagement is required. How it works: the scanner normalizes the target, calls the PentestHint scanner API, collects raw data, and returns evidence, technical explanation, recommendations, and a sample-style output preview with score, risk label, finding table, and remediation guidance. Results should be reviewed by a qualified security professional before production changes are made.
