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

Bioteka is a Croatian non-profit association dedicated to promoting biology and related sciences through educational content such as quizzes, articles, and resources primarily targeting students and educators. The website reflects a niche educational focus with a moderate market position in the Croatian education sector. The technical infrastructure is based on the Xoops CMS platform with legacy JavaScript libraries like jQuery 1.7.2 and includes standard web components such as Google Analytics and a cookie consent mechanism. While the site is functional and provides relevant educational content, it shows signs of technical debt and basic mobile and accessibility optimization. Security posture is moderate with no HTTPS status explicitly confirmed in the HTML content, no visible security headers, and use of outdated libraries posing potential risks. Privacy compliance is addressed with a clear privacy policy and cookie consent banner, indicating GDPR awareness. Overall, the site is trustworthy but would benefit from technical and security modernization to improve resilience and user trust.

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. 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: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL 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

  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"

      • 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';…

  3. 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

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-sized non-profit entity focused on education in biology and natural sciences within Croatia. Its business model centers on providing free educational resources and interactive quizzes to students and educators. The website's market positioning is niche but stable, supported by a domain age of over a decade and consistent WHOIS data. The association maintains active social media channels on Instagram, Twitter, and Facebook, enhancing community engagement. Revenue streams are not evident, consistent with a non-profit model. The partnership ecosystem is limited with no identified commercial partners or subsidiaries. Strategic observations suggest opportunities for growth through modernization of technical infrastructure and enhanced security measures to maintain trust and compliance.

Security posture

The current security maturity level is basic to moderate. Key strengths include the presence of a cookie consent banner and privacy policy, indicating compliance with data protection regulations. However, the use of an outdated jQuery version introduces known vulnerabilities, and the absence of security headers such as Content Security Policy (CSP), X-Frame-Options, and HSTS reduces the site's defense against common web attacks. No incident response or security policy documentation is available, limiting transparency and preparedness. The lack of visible HTTPS enforcement in the provided HTML content is a concern, though it may be enforced at the server level. Overall, the site requires upgrades to its technical stack and implementation of security best practices to mitigate risks and improve compliance.

Recommendations

  1. Upgrade all JavaScript libraries, especially jQuery, to current secure versions to eliminate known vulnerabilities.
  2. Implement comprehensive security headers including CSP, HSTS, X-Frame-Options, and X-Content-Type-Options.
  3. Ensure HTTPS is enforced site-wide and verify SSL/TLS configuration for best practices.
  4. Develop and publish explicit security policies and incident response procedures to enhance transparency and readiness.
  5. Improve mobile optimization and accessibility to enhance user experience and compliance with standards.

Technical notes

Notes

The website is built on the Xoops CMS platform, utilizing legacy JavaScript libraries such as jQuery 1.7.2 and Nivo Slider for UI components. Google Analytics is integrated for visitor tracking, and a cookie consent banner is implemented via cookie-bar.js from a CDN. The site uses multiple CSS stylesheets and JavaScript files hosted on its own domain and external CDNs. Performance is moderate with basic mobile responsiveness and accessibility features. The HTML meta tags are minimal with no Open Graph or JSON-LD structured data present. The domain is hosted under Croatian registrar CARNET, suggesting local hosting. Technical debt is evident from outdated libraries and lack of modern security headers, indicating opportunities for modernization and improved security posture.
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.
