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

ÚJV Řež, a. s. is a Czech-based technical and engineering company specializing in nuclear energy, radioactive waste management, and nuclear medicine. With over 70 years of experience, it serves the energy sector, healthcare, and industrial clients by providing project support, research, and development services. The company maintains a strong market position in the Czech Republic's nuclear and energy industries, offering key services such as safe operation support for energy sources, radiopharmaceutical production, and hydrogen technology development. Technically, the website employs modern web technologies including Google Tag Manager and Google Analytics, with a responsive design and good SEO practices. The site is well-structured, mobile-optimized, and provides a positive user experience. Security-wise, the site uses HTTPS and implements cookie consent mechanisms, but lacks some security headers and explicit security policies, which could be improved. The security posture is solid but could benefit from enhanced transparency through published security policies and vulnerability disclosure mechanisms. The absence of WHOIS data reduces domain registration transparency, but the website content, certifications, and contact details support the company's legitimacy. Overall, the site is professional, trustworthy, and compliant with GDPR requirements. Strategically, the company should focus on improving security headers, publishing incident response and vulnerability disclosure information, and enhancing WHOIS transparency to strengthen trust and compliance further.

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

6 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 Consent Banner found

      GDPR requires explicit consent for non-essential cookies

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

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, LinkedIn, YouTube, Google APIs

      What to do: Document all third-party data sharing in your privacy policy

  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

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

ÚJV Řež operates in a niche but critical sector of nuclear energy and healthcare, leveraging decades of expertise to maintain a competitive edge. Its business model centers on providing specialized technical services and products to energy producers, medical institutions, and research organizations. The company’s revenue streams likely include project contracts, service agreements, and product sales such as radiopharmaceuticals. The target customers are primarily institutional and industrial clients within the Czech Republic and potentially broader European markets. The company’s partnership ecosystem includes collaborations with research institutes and industry players, as evidenced by joint projects and certifications. Growth indicators include active participation in industry events and continuous development in hydrogen technologies and nuclear medicine. The company’s digital presence supports its market positioning but could be enhanced with more transparent security and compliance disclosures.

Security posture

The website demonstrates a moderate to good security maturity level with mandatory HTTPS and cookie consent mechanisms in place. However, the absence of key security headers such as Content-Security-Policy and X-Frame-Options represents a gap that could expose the site to certain web-based attacks. No vulnerabilities or exposed sensitive data were detected in the HTML content. The lack of a published security policy or incident response contact limits transparency and readiness perception. GDPR compliance is supported by clear privacy and cookie policies. The company would benefit from implementing a vulnerability disclosure program and publishing a security.txt file to enhance its security culture and incident response capabilities. Overall, the security posture is adequate but has room for improvement to meet higher standards and regulatory expectations.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a clear security policy and incident response contact information on the website.
  3. Establish and publicize a vulnerability disclosure program or security.txt file.
  4. Enhance WHOIS transparency or provide domain registration details to improve trust.
  5. Regularly audit third-party scripts and tracking tools for security and privacy compliance.

Technical notes

Notes

The website uses a modern tech stack with JavaScript, CSS, Google Tag Manager, Google Analytics, and Google Maps API integration. The HTML is valid and well-structured, supporting good SEO and accessibility basics. Performance is moderate, with room for optimization. Mobile responsiveness is good, ensuring usability across devices. The site lacks a detected CMS, suggesting a custom or proprietary platform. Hosting provider details are not evident from the HTML. Technical risks include missing security headers and potential dependency on third-party scripts that require regular security reviews. Overall, the technical infrastructure supports the business needs but could be enhanced with improved security and performance optimizations.
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.
