Security score

Risk levelMedium

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

U Zlaté Konvice is a small hospitality business operating a restaurant located in the historic center of Prague, specializing in traditional Czech cuisine served in a unique 14th-century cellar setting. The website presents the restaurant's offerings, including live music and special events, targeting tourists and locals interested in cultural dining experiences. The business maintains a moderate market position with clear contact information and partner affiliations. Technically, the website uses legacy JavaScript libraries and common web technologies such as jQuery, Google Analytics, and Fancybox, but lacks modern security headers and updated libraries, which could expose it to vulnerabilities. The absence of WHOIS data limits domain legitimacy verification, although the website content and contact details appear authentic. Privacy and cookie policies are present but basic, with no visible terms of service or security policies. Overall, the website is functional and professionally presented but would benefit from technical and security improvements.

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

7 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 Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  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"

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 restaurant operates in the hospitality sector, focusing on traditional Czech cuisine and cultural experiences in Prague's Old Town Square. Its business model revolves around in-person dining, live entertainment, and special group offers. The website links to multiple partner domains, indicating a networked local hospitality ecosystem. The company targets tourists and local patrons seeking authentic dining experiences. Revenue streams likely include food and beverage sales, event hosting, and group bookings. The website's content quality and branding are consistent, supporting a trustworthy customer experience. However, the lack of detailed corporate information and WHOIS transparency may affect business credibility in digital channels.

Security posture

The website demonstrates a basic security posture with HTTPS enabled (assumed from URL), cookie consent implemented, and no visible exposed sensitive data. However, the use of outdated jQuery 1.7.1 introduces known vulnerabilities, and no security headers such as Content-Security-Policy or X-Frame-Options were detected. There is no public security policy or incident response information available. The absence of WHOIS data reduces trust in domain legitimacy. Overall, the security maturity is low to moderate, with significant room for improvement in library updates, header implementation, and transparency of security practices.

Recommendations

  1. Update all JavaScript libraries, especially jQuery, to the latest secure versions to mitigate known vulnerabilities.
  2. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  3. Ensure HTTPS is properly configured with strong SSL/TLS settings and enforce HTTPS site-wide.
  4. Publish clear security and incident response policies on the website to improve transparency and preparedness.
  5. Improve privacy compliance by expanding the privacy policy to address GDPR requirements and clearly state data retention policies.

Technical notes

Notes

The website relies on legacy JavaScript libraries such as jQuery 1.7.1 and jQuery UI 1.8.13, which are outdated and potentially vulnerable. It uses common plugins like Fancybox and Superfish for UI elements. Google Analytics and Google Tag Manager are used for analytics and tracking. The site appears to be custom-built without a known CMS. Performance is moderate with basic mobile optimization and accessibility features. SEO is basic with meta tags present but no advanced structured data or Open Graph tags detected. Hosting provider and infrastructure details are not discernible from the provided data. The site would benefit from modernization of its tech stack and improved performance and accessibility enhancements.
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.
