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

The website www.helcza.cz represents HELCZA (High Energy Load Czech Assembly), a specialized experimental facility dedicated to cyclic thermal testing of components for future fusion energy devices. The site targets the scientific and engineering community involved in fusion technology development. The business model is focused on research and development within the energy sector, specifically fusion energy. The website presents a professional and consistent branding with good content quality, though it lacks visible contact information and privacy policies. Technically, the site uses modern web technologies including the Brz framework and Bunny Fonts, with moderate performance and good mobile optimization. Security posture is moderate due to lack of visible security headers and unknown SSL configuration. WHOIS data is unavailable, limiting domain trust assessment. Overall, the site is functional and informative but would benefit from enhanced privacy compliance and clearer contact channels.

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

    • 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 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

HELCZA operates as a niche research infrastructure in the energy sector, focusing on fusion device component testing. Its market position is specialized and likely supported by scientific institutions or government research programs. The absence of commercial or e-commerce elements suggests a non-profit or institutional business model. The website does not disclose company registration or VAT information, nor does it provide contact details, which limits direct business engagement. The lack of WHOIS data reduces transparency but may be due to privacy protection. The site does not appear to engage in advertising or extensive user tracking, indicating a focus on informational content rather than commercial exploitation.

Security posture

The website employs HTTPS (implied by canonical URL), but no explicit security headers were detected in the provided data. There is no evidence of security or incident response policies, vulnerability disclosure mechanisms, or data protection officer contacts. No forms were found, reducing risk of input-based vulnerabilities. The absence of privacy and cookie policies indicates potential GDPR compliance gaps. The lack of WHOIS data and registrant information reduces domain trustworthiness. Overall, the security posture is basic and would benefit from implementing standard security headers, publishing privacy and cookie policies, and providing clear security incident contacts.

Recommendations

  1. Implement and publish comprehensive privacy and cookie policies to improve GDPR compliance and user trust.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to enhance protection.
  3. Provide clear contact information including emails and phone numbers for general and security-related inquiries.
  4. Publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  5. Obtain and publish WHOIS information or justify privacy protection to improve domain transparency and trust.

Notes

The website uses a modern front-end stack with HTML5, CSS3, JavaScript, and the Brz framework. Fonts are loaded from Bunny Fonts CDN, and static assets are served via Bunny CDN, indicating a focus on performance and reliability. The site is mobile optimized with responsive design. No CMS or backend technologies were identified from the provided data. Performance is moderate, with no explicit indicators of slow loading or errors. Accessibility is basic, with no advanced features detected. SEO is supported by proper meta tags and Open Graph data. No analytics or tracking scripts were found, indicating minimal user tracking.
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.
