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

The website 'Deset hvězd' is a cultural heritage project managed by the Federation of Jewish Communities in the Czech Republic. It focuses on preserving and promoting Jewish cultural heritage through a network of regional cultural and educational centers located in restored synagogues. The project is part of the European Route of Jewish Heritage, certified by the Council of Europe, and offers exhibitions, cultural programs, and concerts. The target audience is the general public interested in cultural history and education. The business model is non-profit, emphasizing cultural preservation and education. Technically, the website uses a traditional tech stack including jQuery, Owl Carousel, Fancybox, and Google Analytics for tracking. It is built on the Nette Framework, a PHP-based CMS. The site shows moderate performance and basic mobile optimization but uses outdated JavaScript libraries that may pose security risks. SEO and accessibility are basic but functional. From a security perspective, the site uses HTTPS and includes Google Analytics scripts but lacks visible security headers and uses outdated libraries. There are no forms collecting sensitive data, reducing immediate risk, but the absence of privacy and cookie policies indicates compliance gaps. No incident response or vulnerability disclosure information is provided. Overall, the website is trustworthy and professionally presented but would benefit from updating its technical stack, implementing security best practices, and adding privacy and cookie policies to improve compliance and user trust.

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

11 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

  2. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  3. 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.

Business context

Business profile

The Federation of Jewish Communities in the Czech Republic operates this cultural heritage project, positioning itself as a key player in preserving Jewish cultural sites and history within the Czech Republic and Europe. The project leverages partnerships with European cultural institutions and governmental bodies, enhancing its credibility and reach. Its non-profit model focuses on education, cultural preservation, and community engagement through exhibitions and events. The website supports this mission by providing detailed information about the project, its locations, and programs. Growth potential exists through expanding the network of restored synagogues and increasing public engagement. The partnership ecosystem includes European cultural routes and local governmental agencies, which strengthens its strategic position.

Security posture

The website demonstrates a basic security posture with HTTPS enabled and no visible forms collecting sensitive data, reducing attack surface. However, the use of outdated JavaScript libraries such as jQuery 1.10.1 and jQuery Migrate 1.2.1 introduces potential vulnerabilities. The absence of security headers like Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security weakens defense-in-depth. No privacy or cookie policies are present, indicating compliance gaps with GDPR and related regulations. Incident response and vulnerability disclosure mechanisms are not provided, limiting transparency and readiness. Overall, the security maturity is moderate but requires improvements to align with best practices and regulatory requirements.

Recommendations

  1. Update all JavaScript libraries, especially jQuery and jQuery Migrate, to the latest secure versions to mitigate known vulnerabilities.
  2. Implement comprehensive privacy and cookie policies with clear user consent mechanisms to ensure GDPR compliance.
  3. Add and configure security headers such as Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, and Strict-Transport-Security to enhance security posture.
  4. Establish and publish a vulnerability disclosure policy and incident response contact information to improve transparency and security readiness.
  5. Enhance mobile optimization and accessibility features to improve user experience and compliance with accessibility standards.

Technical notes

Notes

The website is built on the Nette Framework with a front-end relying on jQuery 1.10.1, jQuery Migrate 1.2.1, Owl Carousel, and Fancybox for UI components. Google Analytics and Google Tag Manager are used for analytics and tracking. The site has a moderate performance profile with basic mobile responsiveness and SEO optimization. The HTML structure is valid and includes meta tags and Open Graph tags for social sharing. However, the use of outdated JavaScript libraries presents a technical debt and security risk. There is no evidence of modern front-end frameworks or advanced performance optimization techniques. The site could benefit from modernization, including upgrading libraries, improving mobile responsiveness, and enhancing accessibility.
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.
