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

Na Fialce is a small hospitality and cultural center located in Říčany near Prague, operated by Openplace s.r.o. The center caters to sports enthusiasts, film lovers, and fans of quality food and coffee, offering a variety of services including sports facilities, cultural events, cinema, and dining options. The website presents a professional and consistent brand image with good content quality and user experience. Technically, the site uses modern web technologies such as Bootstrap, Google Tag Manager, Facebook Pixel, and Cookiebot for cookie consent management. However, the absence of WHOIS data and explicit privacy and terms policies limits full trust verification. Security posture is moderate with HTTPS usage and cookie consent but lacks visible security headers and detailed security policies. Overall, the site is safe for general audiences and demonstrates a moderate level of digital maturity.

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

3 findings rated critical or high. Fix these first.

  1. 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

  2. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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 hospitality sector, focusing on community engagement through sports and cultural activities. Its market position is local with a target audience of sports and culture enthusiasts. The business model revolves around providing event spaces, sports facilities, and food services. The company maintains social media presence on Instagram and Facebook, enhancing community interaction. The lack of detailed WHOIS and contact information suggests an opportunity to improve transparency and trust. The use of analytics and marketing tools indicates active digital marketing efforts. Growth potential exists through enhanced online presence and formalization of privacy and security policies.

Security posture

The website employs HTTPS and a cookie consent mechanism, reflecting basic compliance with privacy regulations. The integration of Google Tag Manager and Facebook Pixel indicates data tracking practices, but no explicit privacy policy was found to inform users fully. Security headers are not detected, which is a gap in defense-in-depth strategies. No vulnerabilities or malware indicators were found in the content. Incident response and security contact information are absent, limiting readiness for security events. Overall, the security posture is moderate but can be improved by implementing security headers, publishing clear privacy and security policies, and providing incident response contacts.

Recommendations

  1. Implement and publish a comprehensive privacy policy and terms of service on the website.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance security posture.
  3. Provide explicit contact information for security incidents and data protection officer if applicable.
  4. Verify and publish WHOIS domain registration details to improve domain legitimacy and trust.
  5. Conduct regular audits of third-party scripts and tracking tools to ensure compliance and security.

Technical notes

Notes

The website uses a modern tech stack including Bootstrap for responsive design, Google Tag Manager for tag management, Facebook Pixel for marketing analytics, and Cookiebot for cookie consent management. Fonts are loaded via Adobe Typekit. The site appears mobile-optimized with good navigation and SEO meta tags. Performance is moderate with deferred script loading and preloading of critical assets. Accessibility is basic but could be enhanced. Hosting provider and CMS are not explicitly identified. No critical technical debt or vulnerabilities were detected in the provided content.
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.
