The site is mobile-optimized and SEO-friendly, though accessibility could be improved. Security-wise, the site uses HTTPS and implements a detailed cookie consent mechanism compliant with GDPR, but lacks explicit security headers and published security policies. No critical vulnerabilities or suspicious content were detected.

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

  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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  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 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';…

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

BAKALÁŘI software s.r.o. holds a dominant position in the Czech educational software market, with over 60% penetration among schools. Their competitive advantage lies in a comprehensive, modular system tailored to school administrative needs, continuous updates aligned with legislative changes, and flexible deployment options. Revenue streams likely include software licensing, cloud services, and technical support. The target customers are primarily Czech schools, teachers, students, and parents. The company benefits from a strong partnership ecosystem, including EU funding programs and integration with global databases. Strategic observations highlight a focus on user-driven development, extensive customer support, and a growing mobile application presence.

Security posture

The website exhibits a moderate to good security maturity level. It enforces HTTPS and provides a robust cookie consent mechanism with detailed user controls, indicating GDPR compliance. However, the absence of explicit security headers (e.g., CSP, HSTS) and lack of published security or incident response policies represent gaps. No vulnerabilities or exposed sensitive data were found in the HTML content. The site does not provide a vulnerability disclosure policy or security.txt file, which could enhance transparency and incident handling readiness. Overall, the security culture appears adequate but could benefit from formalizing policies and improving technical defenses.

Recommendations

  1. Implement HTTP security headers such as Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a clear security policy and incident response contact information on the website.
  3. Introduce a vulnerability disclosure program or security.txt file to facilitate responsible reporting.
  4. Enhance website accessibility to meet WCAG standards for broader user inclusivity.
  5. Regularly audit and update third-party libraries to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built on a solid technical foundation using widely adopted libraries and frameworks like jQuery, Bootstrap, and Font Awesome. Hosting on Microsoft Azure DNS suggests reliable infrastructure. Performance is moderate with room for optimization. The site is mobile responsive and SEO optimized with proper meta tags and Open Graph data. However, accessibility features are basic and could be improved. The absence of a known CMS indicates a custom or proprietary solution. Technical risks include potential outdated libraries and missing security headers, which should be addressed to maintain operational security and compliance.
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.
