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

Nikola Tesla Network is a small, non-profit cultural and educational project focused on promoting the legacy of Nikola Tesla through an international cultural and touristic route. The website serves as a hub for information about the network, its partners, events, and educational initiatives such as the Teslina STEM Academy. The project is supported by reputable partners including the Croatian National Tourist Board and is co-financed by the European Union, indicating a solid market position within cultural tourism and education sectors. Technically, the website employs a moderate technology stack including jQuery, Modernizr, and various UI plugins, hosted on infrastructure linked to the NETIM registrar and VIT Web Hosting. The site is mobile optimized with good SEO practices and clear navigation, though accessibility features are basic. Security posture is adequate with HTTPS enforced and CSRF protections in forms, but lacks advanced security headers and a formal security policy. Privacy compliance is partial; a cookie policy and consent mechanism are present, but no explicit privacy policy page was found, representing a compliance gap. Contact information is clearly provided, enhancing business credibility. No signs of malicious content or WAF blocking were detected, and the site content is safe for general audiences. Overall, the website is professionally maintained with good content quality and business credibility but would benefit from enhanced privacy and security policies to improve compliance 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

7 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

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  2. 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"

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 Nikola Tesla Network operates in the niche cultural tourism and education market, leveraging Nikola Tesla's global legacy to attract tourists, educational institutions, and partners. Its business model is non-profit, focusing on cultural route promotion, educational workshops, and events. The network has established partnerships with governmental and cultural bodies, enhancing its credibility and reach. The presence of multiple countries and continents in its route map indicates international ambitions. Revenue streams likely include grants, sponsorships, and event participation fees. The project shows growth indicators through active news updates and educational initiatives. Strategic partnerships with the Croatian National Tourist Board and the Council of Europe cultural routes strengthen its market position.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and CSRF tokens implemented in forms, reducing risks of common web attacks. Cookie consent mechanisms align with GDPR requirements, though the absence of a formal privacy policy and security policy reduces compliance completeness. No security headers such as Content-Security-Policy or X-Frame-Options were detected, which could expose the site to clickjacking or content injection risks. There is no visible incident response contact or vulnerability disclosure policy, limiting transparency and readiness. The use of common JavaScript libraries necessitates regular vulnerability assessments to avoid exploitation. Overall, the security posture is adequate but could be significantly improved with formal policies and enhanced header configurations.

Recommendations

  1. Publish a comprehensive privacy policy page to improve GDPR compliance and user trust.
  2. Implement security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Establish and publish an incident response and vulnerability disclosure policy with dedicated contact channels.
  4. Regularly audit and update third-party libraries to mitigate vulnerabilities.
  5. Enhance accessibility features to improve inclusivity and compliance with standards.

Technical notes

Notes

The website uses a combination of jQuery, Modernizr, Google Fonts, and UI plugins like Revolution Slider and Fancybox, indicating a moderately modern but somewhat legacy technology stack. The CMS appears custom or less common, which may pose maintenance challenges. Hosting is provided by a known Croatian hosting provider linked to the registrar NETIM. Performance is moderate with mobile optimization and SEO best practices implemented. However, accessibility is basic and could be improved. The site uses cookies and Google Analytics for tracking, with a consent mechanism in place. Technical risks include potential outdated libraries and lack of advanced security headers. Modernization opportunities include migrating to a more widely supported CMS 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.
