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

The website www.chemtk.cz serves as an integrated portal for the National Technical Library (NTK), University of Chemistry and Technology Prague (VŠCHT), and the Institute of Organic Chemistry and Biochemistry (ÚOCHB). It provides comprehensive access to chemical databases, e-books, journals, and research support services targeted primarily at academic researchers, students, and professionals in chemistry and related fields. The platform is positioned as a key national academic resource in the Czech Republic, operating under a non-profit model with strong institutional affiliations. Technically, the site employs modern web technologies including HTML5, CSS3, JavaScript with jQuery, Bootstrap framework, and Matomo analytics for user tracking. The site is mobile-optimized with good navigation and accessibility features, though some improvements in accessibility and cookie consent mechanisms are recommended. Performance is moderate with a professional design and consistent branding. From a security perspective, the site enforces HTTPS and uses secure forms but lacks explicit security headers and published security policies. No vulnerabilities or exposed sensitive data were detected. The absence of WHOIS data limits domain trust assessment, but the institutional nature and content quality support legitimacy. Privacy compliance is partial, with a privacy policy present but no cookie consent banner. Overall, the site is a well-maintained academic resource with a good security posture and professional presentation. Strategic recommendations include enhancing security headers, implementing cookie consent for GDPR compliance, publishing security and incident response policies, and verifying domain registration details to improve trust and compliance.

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

8 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

  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 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 website operates as a collaborative academic library portal integrating resources from three major Czech institutions. Its market positioning is strong within the national academic and research community, offering specialized chemical and citation databases alongside e-books and journals. The business model is non-profit, focusing on providing access and support rather than commercial revenue. Target customers include university students, researchers, and academic staff in chemistry and technical disciplines. The partnership ecosystem includes NTK, VŠCHT, and ÚOCHB, which enhances resource sharing and service quality. Growth indicators include regular updates, webinars, and integration of new digital tools. The platform's competitive advantage lies in its integrated access to multiple institutional collections and specialized chemical information services.

Security posture

The website demonstrates a moderate to good security maturity level. HTTPS is enforced site-wide, and no sensitive data is exposed in the HTML content. However, the absence of key security headers such as Content-Security-Policy and X-Frame-Options represents a gap that could be exploited in certain attack scenarios. There is no publicly available security or incident response policy, which limits transparency and preparedness communication. The use of Matomo analytics indicates some level of user tracking, but no cookie consent mechanism was found, which may pose GDPR compliance risks. No known vulnerabilities or outdated libraries were detected. Overall, the security posture is adequate for an academic portal but could be improved with enhanced headers, explicit policies, and privacy controls.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  2. Deploy a cookie consent banner and mechanism to ensure GDPR compliance and inform users about tracking.
  3. Publish a clear security policy and incident response contact information to improve transparency and readiness.
  4. Regularly audit and update third-party scripts and libraries to prevent vulnerabilities.
  5. Verify and publish domain registration details to enhance trust and legitimacy perception.

Technical notes

Notes

The website is built on a modern technology stack featuring HTML5, CSS3, JavaScript with jQuery, and Bootstrap framework for responsive design. It uses Modernizr for feature detection and Matomo for analytics tracking. The site is mobile-optimized with good navigation and accessibility, though some accessibility improvements could be made. Performance is moderate, with no major issues detected. The absence of a CMS or hosting provider information limits deeper infrastructure analysis. The site uses HTTPS with a presumably strong SSL configuration. Technical debt appears low, but the lack of security headers and cookie consent mechanisms indicates areas for modernization and compliance enhancement.
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.
