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

NetStránky.cz is a Czech legacy website offering a free website creation tool primarily targeting individuals and small businesses seeking simple web presence solutions without programming knowledge. The project has been officially terminated in its original form due to unprofitability and increasing administrative and legal burdens, now operating only in a limited capacity for remaining users. The website content is minimal and primarily informational, with links to administration and related services such as rychlost.cz, a speed testing platform. Technically, the site uses outdated jQuery 1.10.2 and custom PHP scripts, with no clear evidence of modern security practices or HTTPS enforcement from the provided data. Security posture is weak due to lack of visible security headers, no cookie consent mechanism, and absence of contact or incident response information. WHOIS data is unavailable, which negatively impacts trust and legitimacy assessments. Overall, the site appears to be a legacy platform with limited active development or support.

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 model was based on providing a free website builder tool with optional paid services, targeting Czech-speaking users. The market position is niche and diminished due to project termination. The company operates at a small scale with limited online presence and no visible certifications or trust signals. The partnership with rychlost.cz indicates some ecosystem integration. Revenue streams likely included paid upgrades or domain hosting services. The lack of contact information and minimal content suggests low growth and limited customer engagement. Strategic observations highlight the need for modernization or migration to alternative platforms.

Security posture

The security maturity level is low. The absence of WHOIS data, lack of HTTPS confirmation, missing security headers, and outdated JavaScript libraries expose the site to potential vulnerabilities. No privacy or cookie consent mechanisms are implemented, risking non-compliance with GDPR. Incident response and security policy information are not provided, indicating poor readiness for security incidents. The site does not demonstrate adherence to recognized security frameworks or certifications. Overall, the security posture is insufficient for modern standards and requires significant improvements to protect user data and maintain trust.

Recommendations

  1. Implement HTTPS with a valid SSL/TLS certificate and enforce secure connections site-wide.
  2. Update all JavaScript libraries, especially jQuery, to current secure versions to mitigate known vulnerabilities.
  3. Add comprehensive privacy and cookie policies with explicit consent mechanisms to comply with GDPR.
  4. Publish clear contact information including security incident response contacts and data protection officer details.
  5. Introduce security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.

Technical notes

Notes

The website relies on legacy technologies including jQuery 1.10.2 and custom PHP scripts for CSS and counters. The HTML structure is basic with minimal SEO optimization and no evident mobile responsiveness enhancements. Performance is moderate but could be improved by modernizing the tech stack and optimizing assets. Accessibility features are minimal, and no CMS or hosting provider information is discernible. The site lacks modern frameworks or platforms, indicating technical debt and potential risks for maintainability and security.
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.
