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

5 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

      Third-party services without privacy policy

      Detected services: Facebook

      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

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

  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.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • 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

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 institution holds a strong market position as a regional gymnasium with a long tradition and modern educational offerings. Its business model is public education, focusing on secondary education with international project participation. The school maintains partnerships with regional authorities and educational bodies, enhancing its credibility and resource access. The website supports its business goals by providing relevant information, contact details, and links to student systems. Growth indicators include active Erasmus+ projects and digital innovation in teaching. The partnership ecosystem includes regional government, ministry of education, and exam boards, supporting operational and academic excellence.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and no exposed sensitive data. Use of Google reCAPTCHA and Facebook SDK indicates some tracking but also security controls. However, the absence of explicit security policies, incident response contacts, and security headers suggests room for improvement. No vulnerabilities or malware indicators were found. GDPR compliance is basic but present. The site lacks a vulnerability disclosure policy or security.txt file, which could enhance transparency and trust. Overall, the security posture is adequate for an educational institution but should be enhanced to meet higher standards.

Recommendations

  1. Implement comprehensive security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  2. Publish an incident response policy and provide dedicated security contact channels (e.g., security@ or abuse@ emails).
  3. Enhance cookie consent mechanisms to actively block tracking scripts until user consent is given.
  4. Conduct regular security audits of third-party scripts and dependencies to mitigate vulnerabilities.
  5. Consider adding a vulnerability disclosure policy or security.txt file to improve transparency and trust.

Technical notes

Notes

The website uses a combination of jQuery, Remodal, Blueimp Gallery, BxSlider, and Font Awesome for UI and interactivity. The CMS is custom or unknown, with no popular CMS detected. Performance is moderate with some modern features like responsive design and mobile optimization. SEO is supported by proper meta tags and structured navigation. The site lacks advanced accessibility features but provides basic usability. Hosting provider details are not evident. The technical stack is stable but could benefit from modernization and improved 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.
