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

BDSAT.cz is the official website for the BDSAT nanosatellite project managed by BD SENSORS s.r.o., a Czech company specializing in electronic pressure measurement technology. The website provides detailed information about the nanosatellite, its mission to test pressure sensors and supercapacitor banks in space, and support for the radio amateur community. The company is positioned as a significant global player in its sector with government-backed funding and partnerships with academic and industry entities. Technically, the website uses modern web technologies including JavaScript libraries and Google Analytics for tracking, hosted likely via Active24 in the Czech Republic. The site is well-designed, mobile-optimized, and offers clear navigation, though it lacks explicit privacy and cookie policies and security headers. Security posture is moderate with HTTPS usage but missing advanced headers and incident response contacts. Overall, the domain registration data aligns well with the business claims, indicating legitimacy and trustworthiness.

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.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

The company BD SENSORS s.r.o. operates in the technology sector focusing on nanosatellite payload development and testing. Their business model includes technology validation in space and community engagement with radio amateurs. The project is supported by government funding and partnerships with academic institutions and industry players, enhancing credibility and market position. The website reflects a medium-sized enterprise with a clear focus on innovation and technology testing. The presence of partner logos and government program mentions indicates a strong partnership ecosystem. Revenue streams likely include technology sales, research contracts, and government grants. The company targets technology enthusiasts, space researchers, and radio amateurs, positioning itself as a niche but credible player in the space technology domain.

Security posture

The website demonstrates a moderate security posture with HTTPS enabled and no visible exposed sensitive data. However, it lacks important security headers such as Content-Security-Policy and X-Frame-Options, which could mitigate common web attacks. There is no visible privacy or cookie policy, which is a compliance gap under GDPR. No incident response or vulnerability disclosure information is provided, limiting transparency in security management. The absence of forms reduces attack surface but also limits user interaction. The use of Google Analytics without a consent mechanism may pose privacy compliance risks. Overall, the security maturity is basic to moderate, with room for improvement in headers, policies, and transparency.

Recommendations

  1. Implement comprehensive privacy and cookie policies with clear GDPR compliance statements.
  2. Add security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection.
  3. Publish incident response contact information and consider adding a vulnerability disclosure policy or security.txt file.
  4. Introduce cookie consent mechanisms to comply with privacy regulations and improve user trust.
  5. Enhance accessibility features to improve inclusivity and SEO.

Technical notes

Notes

The website is built with standard HTML5, CSS3, and JavaScript, utilizing the locomotive-scroll library for smooth scrolling effects and Google Analytics for user tracking. The site is hosted likely by Active24, a Czech hosting provider, consistent with the domain registrar. Performance is moderate with some external dependencies on CDN services. The site is mobile-optimized with responsive design elements. SEO is basic with meta viewport and title tags but lacks structured data or Open Graph metadata. No CMS is detected, suggesting a custom or static site. Technical risks include missing security headers and lack of privacy compliance mechanisms. Modernization opportunities include adding structured data, improving accessibility, and enhancing security configurations.
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.
