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

ISIC.cz is a Czech Republic-based organization focused on issuing internationally recognized student and youth discount cards such as ISIC, ISIC Scholar, Teacher ISIC, IYTC, and AliveID. Established since 2000, the website reflects a mature business with a clear target audience of students and young people in the Czech Republic. The site uses modern web technologies including jQuery, Swiper, Select2, Leaflet, and integrates multiple tracking and advertising services managed through Cookiebot and Google Tag Manager. The technical infrastructure is hosted on Amazon AWS, ensuring reliable performance and scalability. Security posture is solid with HTTPS enforced and a comprehensive cookie consent mechanism, though there is room for improvement in security headers and explicit privacy and terms documentation. Overall, the site is professional, trustworthy, and compliant with cookie consent regulations but lacks visible contact and security policy information.

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

3 findings rated critical or high. Fix these first.

  1. 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 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';…

  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

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 business operates in the education sector, providing essential student identification and discount services. Its market position is strong given the domain age and consistent branding. Revenue streams likely include card issuance fees and partnerships with merchants offering discounts. The company leverages a partner ecosystem including e-commerce and online platform domains. Growth indicators include modern web infrastructure and extensive use of analytics and marketing tools. However, the absence of visible contact and legal documents may limit trust for some users.

Security posture

The website demonstrates a moderate to good security maturity level with HTTPS and cookie consent compliance. However, the lack of security headers and absence of a security.txt or incident response contact reduces its security transparency. No vulnerabilities or exposed sensitive data were detected in the provided content. Compliance with GDPR is partially indicated by cookie consent but lacks explicit privacy policy documentation. Incident response readiness and security culture indicators are not visible, suggesting areas for enhancement.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service accessible from the homepage.
  2. Implement standard security headers such as Content-Security-Policy, X-Frame-Options, and X-XSS-Protection.
  3. Add a security.txt file to facilitate vulnerability disclosure and incident reporting.
  4. Provide clear contact information including company emails and phone numbers for customer and security inquiries.
  5. Regularly audit third-party scripts and tracking services to minimize privacy risks and improve compliance.

Technical notes

Notes

The website uses a modern and diverse technology stack including jQuery, Swiper, Select2, and Leaflet for interactive UI and mapping features. Hosting on AWS provides robust infrastructure support. Performance is moderate with deferred loading of scripts and use of CDN-hosted libraries. SEO is well addressed with meta tags and Open Graph data. Accessibility is basic but could be improved. The site is mobile optimized and uses Google Fonts for typography. Technical risks include reliance on multiple third-party tracking and advertising services which require ongoing privacy management.
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.
