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

12 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 project positions itself as a thought leader in Czech tax policy reform, targeting policymakers, economists, and the general public interested in fiscal matters. It leverages detailed economic studies and expert endorsements to influence public discourse and policy decisions. The business model is non-profit and research-driven, focusing on public education and advocacy rather than commercial services. Partnerships with academic and research institutions strengthen its market position and credibility. The website content is rich with detailed proposals, impact analyses, and downloadable study materials, indicating a commitment to transparency and depth. The absence of phone contacts and physical addresses suggests a primarily digital and research-focused operation.

Security posture

The website employs HTTPS and integrates standard security best practices, including cookie consent and no exposure of sensitive data. However, it lacks publicly available security policies, incident response plans, or vulnerability disclosure mechanisms, which are recommended for transparency and preparedness. No security headers were explicitly detected in the HTML, suggesting potential room for improvement in HTTP header security configurations. The use of reputable hosting and modern frameworks reduces risk, but formalizing security documentation and response channels would enhance trust and resilience.

Recommendations

  1. Publish a dedicated security policy and incident response plan on the website.
  2. Implement and verify HTTP security headers such as X-Frame-Options, Content-Security-Policy, and Referrer-Policy.
  3. Add a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Consider providing additional contact channels such as phone numbers or physical addresses for enhanced credibility.
  5. Maintain and regularly update privacy and cookie policies to ensure ongoing GDPR compliance.

Technical notes

Notes

The website is built on a modern React and Next.js stack, ensuring server-side rendering and good SEO performance. It uses web fonts, responsive images, and preloading techniques to optimize performance. Analytics are implemented via Google Tag Manager and Matomo, balancing commercial and open-source tracking. Hosting is provided by a Czech hosting company, aligning with the target audience. The site is mobile-optimized with excellent accessibility and navigation clarity. No CMS is detected, indicating a custom-built solution. The technical implementation is robust, with fast loading times and clean markup, though explicit security headers could be improved.
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.
