SecURL: Website Security Check

SecURL shows how secure a website or web service looks from the outside. Paste in a URL, wait a few seconds, and get a letter grade from A to F, a score out of 100, and a clear breakdown of what contributed to the result. No credentials, special access, or setup required.

The scan covers the signals attackers check first: HTTP security headers, TLS configuration, cookie attributes, DNS records, certificate health, and domain posture. Every finding includes a severity level, a plain-language explanation, and practical guidance on what to fix.

The score drivers panel shows exactly which checks are helping or hurting the grade and by how much, so you are never left guessing why a site scored the way it did.

Add any URL to your monitor list and rescan it with one tap whenever you want a fresh check. SecURL shows the previous grade alongside the new one, making regressions easy to spot. Your scan history is stored on-device and available offline.

SecURL is built for developers checking deployments before release, security teams doing quick vendor or supplier reviews, IT professionals assessing third-party posture, and anyone who wants a fast, honest read on whether a site takes security seriously.

No account required. No login. The only data that leaves your device is the URL you choose to scan.
