Risk levelMedium

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 full operations due to unprofitability and increasing administrative burdens. It now operates in a limited capacity for remaining users and also runs a related internet speed testing service, Rychlost.cz. The website content is minimal and primarily informational, with no active marketing or extensive business contact details. Technically, the site uses an outdated jQuery version and custom PHP scripts, with basic CSS styling and limited mobile optimization. Security posture is weak, lacking modern security headers and privacy compliance mechanisms. The absence of WHOIS data and domain registration details further reduces trust and transparency. Overall, the site appears to be in maintenance mode rather than active growth or development.

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, specifically in web hosting and website creation tools. Its market position is diminished due to project termination and limited ongoing service. The business model was freemium or free website creation, targeting individuals or small users without programming skills. Revenue streams and growth indicators are not evident from the site. The partnership ecosystem includes the related service rychlost.cz. The lack of clear contact information and business credentials limits credibility and customer engagement.

Security posture

The security maturity level is low. The site lacks HTTPS enforcement details, modern security headers, and privacy compliance mechanisms such as cookie consent banners. The use of an outdated jQuery library introduces potential vulnerabilities. No incident response or security policy information is provided. Data protection officer or vulnerability disclosure information is absent. The site collects minimal user data via tracking pixels but does not demonstrate GDPR compliance. Overall, the security posture exposes the site to moderate risk and compliance gaps.

Recommendations

  1. Upgrade all JavaScript libraries to supported, secure versions to mitigate vulnerabilities.
  2. Implement HTTPS enforcement and modern security headers (CSP, HSTS, X-Frame-Options).
  3. Add clear privacy and cookie policies with user consent mechanisms to comply with GDPR.
  4. Publish contact information and security incident response details to improve trust and transparency.
  5. Conduct a full WHOIS domain registration update or disclosure to enhance legitimacy and reduce suspicion.

Technical notes

Notes

The website uses a custom CMS with PHP backend scripts and jQuery 1.10.2 on the frontend. CSS is custom and includes multiple stylesheets. Performance is moderate but could be improved with modern frameworks and optimization. Mobile optimization and accessibility are basic, limiting user experience on diverse devices. SEO is minimal with basic meta tags but no structured data or Open Graph tags. The site lacks modern technical security controls and does not appear to use a CDN or advanced hosting provider features. Technical debt is evident from outdated libraries and minimal modernization.
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.
