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

6 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. 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

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3

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, offering comprehensive solutions tailored to schools' administrative and communication needs. Their business model combines SaaS and on-premise deployments, catering to diverse school IT environments. The company benefits from strong partnerships with EU and national education bodies, enhancing credibility and funding opportunities. Testimonials from multiple schools highlight user satisfaction and system adaptability. The company targets schools, teachers, students, and parents, focusing on ease of use and legislative compliance. Growth indicators include a large user base and continuous product updates aligned with educational regulations.

Security posture

The website demonstrates a moderate security maturity level with HTTPS usage and a detailed cookie consent mechanism supporting GDPR compliance. However, the absence of explicit security headers (such as CSP, HSTS, X-Frame-Options) and lack of published security or incident response policies represent gaps. No vulnerabilities or exposed sensitive data were detected in the HTML content. The site does not provide a security.txt or vulnerability disclosure channel, limiting transparency for security researchers. Overall, the security posture is adequate for a public-facing informational site but could be improved to meet higher standards expected for handling sensitive educational data.

Recommendations

  1. Implement and enforce security headers including Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options.
  2. Publish a clear security policy and incident response contact information on the website.
  3. Add a terms of service page to clarify user rights and obligations.
  4. Consider creating and publishing a security.txt file to facilitate vulnerability reporting.
  5. Regularly audit and update third-party libraries to mitigate potential vulnerabilities.

Technical notes

Notes

The website uses a robust and modern technology stack with popular libraries such as jQuery, Bootstrap, and DataTables, ensuring responsive design and interactive features. Hosting on Microsoft Azure DNS indicates reliable infrastructure. Performance is moderate, with potential for optimization. The site is mobile-friendly and SEO-optimized with proper meta tags and Open Graph data. No CMS was detected, suggesting a custom-built solution tailored to the business needs. Accessibility is basic and could be enhanced to improve usability for all users. Overall, the technical implementation supports the business goals effectively but could benefit from performance tuning and accessibility improvements.
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.
