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

Bistro Národní operates as a hospitality and catering service located within the main building of the Academy of Sciences of the Czech Republic in Prague. It provides daily lunch menus, coffee, snacks, catering for events, and conference room rentals. The website is professionally designed, targeting institutional clients and visitors to the Academy. The business model focuses on serving a niche market within a government/non-profit research environment, leveraging its association with the Academy for trust and credibility. Technically, the website uses OpenCms CMS with modern JavaScript libraries such as jQuery and Slick Carousel. It employs Google Fonts and Font Awesome for styling and icons. The site is mobile-optimized and provides a good user experience with clear navigation and relevant content. Analytics are implemented via Plausible, indicating a privacy-conscious approach to user tracking. From a security perspective, the site uses HTTPS but lacks visible security headers and cookie consent mechanisms, which are recommended for compliance with EU regulations. No critical vulnerabilities or exposed sensitive data were detected. The absence of WHOIS data limits domain registration trust analysis, but the website's content and institutional affiliation strongly indicate legitimacy. Overall, the website presents a trustworthy and professional digital presence for Bistro Národní, with room for improvement in security headers and privacy compliance to enhance user trust and regulatory adherence.

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.

Priority findings

9 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"

      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      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

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

Bistro Národní holds a niche position serving the hospitality needs of the Academy of Sciences of the Czech Republic and its visitors. Its competitive advantage lies in its institutional affiliation, offering catering and conference services within a prestigious government research environment. Revenue streams likely include daily meal sales, catering contracts, and conference room rentals. The target customers are primarily employees, researchers, and visitors of the Academy, as well as event attendees. The partnership ecosystem includes related hospitality and cultural sites, enhancing service offerings and brand recognition. The website's professional presentation and consistent branding support its market presence and growth potential within its specialized sector.

Security posture

The website demonstrates a moderate security maturity level. HTTPS is enforced, and no sensitive data is exposed in the HTML. However, the lack of security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security reduces protection against common web attacks. The absence of a cookie consent mechanism may pose compliance risks under GDPR. Forms are present but require validation and security review to prevent injection or abuse. Incident response and security policy information are not publicly available, indicating potential gaps in transparency and readiness. Overall, the security posture is adequate for the business type but would benefit from enhancements to align with best practices and regulatory requirements.

Recommendations

  1. Implement comprehensive security headers including CSP, X-Frame-Options, and HSTS to strengthen web security.
  2. Add a cookie consent banner and mechanism to ensure GDPR compliance and user privacy transparency.
  3. Regularly update and audit third-party libraries and scripts to mitigate vulnerabilities.
  4. Conduct a security audit of all forms and input handling to prevent injection and abuse.
  5. Publish a clear security policy and incident response contact information to improve transparency and trust.

Technical notes

Notes

The website is built on the OpenCms platform, utilizing modern JavaScript libraries such as jQuery and Slick Carousel for interactive elements. Google Fonts and Font Awesome enhance visual appeal. The site is mobile responsive and provides a good user experience with clear navigation and structured content. Performance is moderate, with deferred script loading improving load times. SEO optimization is basic, with meta tags present but no advanced structured data or Open Graph tags detected. Accessibility features are minimal but functional. Hosting provider details are not disclosed. Technical risks include missing security headers and potential outdated libraries, which should be addressed to maintain operational integrity 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.
