What this page helps you understand
TLS problems are often easy to fix but costly when missed. Fixnx checks the public transport layer and highlights browser-facing weaknesses.
What this scan checks
HTTPS response
Certificate validity
HTTP redirect
HSTS
Mixed content
Insecure forms
TLS checks are a launch requirement
Users expect HTTPS everywhere. Search engines, browsers, and customers all treat broken transport security as a trust issue.
Fixnx checks whether HTTPS works, whether HTTP redirects safely, and whether page content creates insecure browser behavior.
Run this check after DNS changes, CDN changes, certificate renewals, and hosting migrations.
Example Fixnx finding
Issue: Incomplete HTTPS hardening
Risk: Medium
Evidence: HTTPS worked, but strict transport hardening was missing or inconsistent.
Recommended fix: Redirect HTTP to HTTPS, fix certificate issues, and add HSTS after confirming all subdomains are ready.
Clear HTTPS behavior and HSTS reduce downgrade risk and help visitors reach the canonical secure site.
What to fix first
- Critical exposed files, admin panels, secrets, or takeover paths.
- Broken HTTPS, missing redirects, weak SSL/TLS behavior, or unsafe cookie handling.
- Confirmed injection, XSS, access-control, authentication, or sensitive API evidence.
- High-impact security headers and browser protections that reduce attack impact.
- Medium and low hardening recommendations after the risky public evidence is fixed.

FAQ
Does SSL/TLS scanning check the certificate?
Yes. Fixnx checks public HTTPS behavior and certificate-related signals available during the scan.
Is HSTS always required?
HSTS is a strong protection for HTTPS sites, but it should be enabled carefully once HTTPS is stable.
What does SSL & TLS Security Check check first?
It starts with https response, then reviews certificate validity, http redirect, and other public signals that can be checked safely from outside the site.
Can I use SSL & TLS Security Check on any website?
Only scan websites you own or have explicit permission to test. Fixnx is built for defensive security checks and website protection. Unauthorized scanning may be illegal.
Does SSL & TLS Security Check prove a site is completely secure?
No. A scan reports the public evidence it collected during a bounded test. It helps you find visible risk, but it cannot guarantee that every private workflow or server-side issue is safe.
Can Fixnx help me understand how to fix the findings?
Yes. Fixnx reports include evidence, severity, confidence, and remediation guidance so owners, developers, and security teams can decide what to fix first.
