How secure is that website, really?
Run a free, fully passive security scan — nothing is installed on the target and no traffic touches it beyond ordinary public requests. HTTPS & TLS health, security headers, cookie flags, exposed files such as .env and .git, Certificate Transparency subdomains, DNS & email security, and outdated software matched against live CVE intelligence — rolled into one 0–100 score.

What this demo shows — and what it doesn't
This free demo returns the same summary the API's free BASIC plan returns: the score, the grade, pass/fail per check category and finding counts. The full report on RapidAPI lists every individual finding with the evidence behind it and concrete remediation advice, adds scan history with change diffs between scans, and unlocks Nuclei-powered deep scans (single or batch) on the PRO plan.
Demo limit: 5 scans per hour per address. Scans are passive and only use publicly reachable information about the target.
