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

GNSS Centre of Excellence is a Czech national center coordinating GNSS activities, focusing on applications in aviation, railways, roads, and public administration. The organization partners with key governmental and commercial entities such as the Ministry of Transport and Prague Airport, positioning itself as a critical hub for GNSS technology development and validation in the Czech Republic. The website reflects a professional and consistent brand image, targeting government institutions and commercial sectors involved in satellite navigation and communication technologies. Technically, the site is built on WordPress with multilingual support and gallery plugins, hosted by WEDOS, a Czech hosting provider. Performance and mobile optimization are moderate, with room for improvement in accessibility and SEO. Security posture is solid with HTTPS enforced and no visible vulnerabilities, but lacks advanced security headers and formal policies. Privacy compliance is weak due to absence of privacy and cookie policies. Overall, the site is trustworthy and professionally maintained but would benefit from enhanced privacy and security disclosures.

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 GNSS Centre operates as an important entity within the transportation and government sectors, providing specialized GNSS services and research. Its business model revolves around partnership and coordination rather than direct commercial sales, focusing on delivering value through expertise and collaboration. The center's market position is strong nationally, supported by government backing and strategic partnerships. Growth indicators include active participation in studies and events related to satellite communication and navigation. The absence of direct e-commerce or advertising suggests a non-profit or government-funded operational model. The partnership ecosystem includes European GNSS Agency (EUSPA) and the Czech Ministry of Transport, enhancing credibility and reach.

Security posture

The website demonstrates a mature security posture with mandatory HTTPS and no exposed sensitive data. However, it lacks implementation of key security headers such as Content-Security-Policy and X-Frame-Options, which could mitigate certain attack vectors. No vulnerability disclosure or incident response information is provided, which is a gap in security transparency. The absence of privacy and cookie policies also indicates incomplete compliance with GDPR and related regulations. Overall, the security maturity is moderate, suitable for an informational site but requiring improvements to meet higher compliance and security standards.

Recommendations

  1. Implement and publish comprehensive privacy and cookie policies to improve GDPR compliance.
  2. Add security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection.
  3. Establish a vulnerability disclosure policy and incident response contact information to improve security transparency.
  4. Enhance mobile responsiveness and accessibility to improve user experience across devices.
  5. Regularly update WordPress core and plugins to mitigate risks from outdated software.

Technical notes

Notes

The website is built on a stable WordPress platform with common plugins for multilingual support and image galleries. Hosting is provided by WEDOS, a reputable Czech hosting provider. The site uses modern web fonts and jQuery libraries, though some scripts are slightly dated. Performance is moderate with no major issues detected, but mobile optimization is basic. SEO is supported by proper meta tags and structured navigation. There is no evidence of advanced caching or CDN usage. Technical debt appears low but could be reduced by updating plugins and improving accessibility features.
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.
