Website Security Scanner
Nyrolo Trust is a website security scanner. Enter any URL and it checks the site's HTTPS setup, SSL/TLS certificate, and security headers against the live site, then combines the results into a single 0–100 trust score you can track over time.

What a website security scanner checks
A website security scanner requests a site the way a browser does and inspects what comes back — no login or source code required. Nyrolo focuses on the externally observable transport and header layer:
HTTPS setup
Whether plain HTTP requests are redirected to HTTPS instead of being served over an unencrypted connection, and whether a Strict-Transport-Security header tells browsers to stay on HTTPS for future visits.
SSL/TLS certificate
Whether the site presents a valid, trusted, in-date TLS certificate that matches the hostname it's serving — the difference between a padlock and a full-page browser warning.
Security headers
Whether response headers like Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, and Referrer-Policy are set, whether the server discloses version fingerprints it doesn't need to, whether the page loads insecure mixed content, and whether cookies carry the Secure flag.
Every scan runs the same ten weighted checks:
- HTTPS enforced
- Valid TLS certificate
- Strict-Transport-Security
- Content-Security-Policy
- Clickjacking protection
- MIME-sniffing protection
- Referrer-Policy
- Server fingerprint hidden
- No mixed content
- Secure cookie flags
Each check is explained in full on the features page. If you'd rather run through them by hand first, our website security checklist walks through each one.
What you get with Nyrolo
The scan is only useful if you can read it and come back to it. Every scan gives you:
A 0–100 Trust Score
The checks are weighted and combined into one number, so you can tell at a glance whether a site is strong (80–100), needs work (50–79), or at risk (below 50).
A full results breakdown
Every check is listed individually with a plain-English explanation of what was found — and, for anything short of a pass, a specific recommendation for what to change.
Scan history
Every scan is saved to your account and searchable by URL, so you can go back and see what a site looked like on the day you checked it.
Tracking over time
Re-scan after a fix, a deploy, or a hosting change and compare the new score against the old one to see whether a site's security is improving or slipping.

How Nyrolo runs the scan
01
Enter a website URL
Paste any site — your own, a client's, or one you're evaluating before you trust it with data.
02
Nyrolo performs the scan
It makes real requests to the live site and inspects the HTTPS redirect, TLS certificate, and response headers. Nothing is cached or estimated.
03
Review the Trust Score and results
Get a 0–100 score with the full check-by-check breakdown and recommendations for anything that didn't pass.
What this scanner does not cover
A clean scan is a useful baseline, not a full security review. Nyrolo checks the externally observable transport and header layer only. It is not:
- a penetration test
- a full application or source-code security audit
- a dependency or supply-chain audit
- a guarantee that a website is safe or free of malware
Application logic, authentication and authorization, infrastructure configuration, and backups are all separate areas of security work, outside what this scan checks. Treat a strong trust score as a solid starting point for your own judgment, not a certification.
