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. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: RDP

      Port 3389 (RDP) is publicly accessible - RDP - Remote Desktop, prime ransomware target

      What to do: Immediately restrict access to RDP using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  4. 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"

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 · found on this site
  • 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 organization operates as a small non-profit focused on environmental conservation and community volunteerism. Its market position is local and community-driven, with a strong emphasis on volunteer engagement and event organization. The business model relies on community participation and possibly donations or sponsorships, though no direct monetization is visible on the site. The target audience includes local residents, environmental volunteers, and supporters of ecological initiatives. The presence of social media channels and multimedia content supports outreach and engagement. The organization appears stable with a consistent brand presence but lacks advanced digital marketing or e-commerce capabilities. Partnerships or subsidiaries are not evident from the data.

Security posture

The website demonstrates a basic security posture with HTTPS usage implied but no explicit security headers detected. The use of outdated JavaScript libraries (jQuery 2.1.4) and Flash content introduces potential vulnerabilities. No privacy or cookie policies are present, indicating GDPR compliance gaps. The site does not expose sensitive data in the HTML, which is positive. Tracking via Google Analytics and Facebook SDK is implemented but without visible user consent mechanisms. Incident response and security policies are not disclosed. Overall, the security maturity is low to moderate, with recommendations to update libraries, implement security headers, and add privacy compliance documentation.

Recommendations

  1. Update all JavaScript libraries to current secure versions and remove deprecated Flash content.
  2. Implement comprehensive privacy and cookie policies with clear user consent mechanisms to ensure GDPR compliance.
  3. Add security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to enhance protection.
  4. Provide explicit contact information including emails and phone numbers for better user trust and compliance.
  5. Modernize website design and improve mobile responsiveness and accessibility to enhance user experience and SEO.

Technical notes

Notes

The website uses a legacy tech stack primarily based on jQuery 2.1.4 and jQuery UI 1.11.4, along with jBox and Blueimp Gallery for UI components. Flash content is embedded via SWFObject, which is deprecated and unsupported in modern browsers. Google Analytics and Facebook SDK scripts are loaded asynchronously for tracking and social integration. The site appears custom-built without a known CMS. Hosting is provided by a Czech hosting provider (cesky-hosting.eu). Performance is moderate with basic mobile optimization and accessibility. SEO is basic with minimal meta tags and no structured data or Open Graph tags detected. The site would benefit from modernization to improve performance, security, and compliance.
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.
