0–100, higher is better. How it is calculated

NetStránky.cz is a Czech-based legacy free website builder platform that has ceased its original form due to unprofitability and increased administrative and legal burdens. It continues to operate in a limited capacity for remaining users and promotes related services such as Rychlost.cz for internet speed testing and the upcoming Fakturomat.cz invoicing software. The website content is minimal and primarily informational, targeting individuals or small users seeking simple website creation tools. The technical infrastructure is basic, relying on older JavaScript libraries and custom CMS solutions, with no evidence of modern frameworks or advanced hosting details. Security posture is weak due to lack of visible HTTPS enforcement, absence of security headers, and no published security or incident response policies. WHOIS data is unavailable, reducing transparency and trustworthiness. Overall, the site presents a low-risk profile but lacks modern security and privacy compliance features.

This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

8 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

  2. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

The business operates in the technology sector, focusing on website creation tools and related online services. Its market position is that of a legacy service with limited active development or growth. Revenue streams appear minimal or non-existent from the free website builder itself, with potential future monetization through ancillary services like invoicing software. The target customer segment includes individuals and small users needing simple web presence solutions. Partnerships with related domains such as rychlost.cz and fakturomat.cz indicate an ecosystem approach. The lack of updated WHOIS data and minimal contact information suggest limited operational transparency and possibly a small organizational size.

Security posture

The security maturity level is low. The absence of HTTPS confirmation and security headers indicates potential vulnerabilities to interception and clickjacking. No incident response or security policy information is published, and no vulnerability disclosure or security.txt files are found. The site uses outdated JavaScript libraries, which may expose it to known vulnerabilities. Data protection and GDPR compliance indicators are minimal, with no cookie consent mechanisms detected. Overall, the site is at risk of security and compliance gaps that could impact user trust and data safety.

Recommendations

  1. Implement HTTPS with a valid SSL/TLS certificate and enforce secure connections site-wide.
  2. Add essential security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Publish clear privacy and cookie policies with consent mechanisms to improve GDPR compliance.
  4. Establish and publicize a security policy and incident response contact information.
  5. Update JavaScript libraries and technical stack to modern, secure versions to reduce vulnerability exposure.

Technical notes

Notes

The website uses an outdated jQuery version (1.10.2) and custom CSS and JavaScript files, indicating a legacy technical stack. The CMS appears proprietary and custom-built. Performance is moderate but could be improved with modern optimization techniques. Mobile optimization and accessibility are basic, with no explicit features detected. SEO is minimal with basic meta tags but no advanced structured data or Open Graph tags. Hosting provider details are not discernible from the data. The site lacks modern frameworks or platforms, suggesting technical debt and potential modernization opportunities.
Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
