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

Ostravská univerzita is a large public university based in Ostrava, Czech Republic, providing a wide range of higher education programs, research activities, and community services. The website serves multiple audiences including prospective students, current students, academic staff, alumni, and partners. It features comprehensive information about faculties, research projects, international cooperation, and student support services. The university holds the HR Award certification, indicating a commitment to human resources excellence. Technically, the website uses a traditional tech stack including jQuery and jQuery UI, with additional libraries like Lightbox and FontAwesome. The site is mobile responsive and well-structured with good SEO practices. Security is reasonably well implemented with HTTPS and some security headers, although there is room for improvement by adding more headers and updating older libraries. The security posture is solid with no visible vulnerabilities or exposed sensitive data. Privacy compliance is strong, with clear GDPR and cookie policies and a consent mechanism. Contact information is prominently displayed, enhancing business credibility. However, the absence of WHOIS data reduces transparency and trust slightly. Overall, the website is professional, trustworthy, and well-maintained, supporting the university's mission and services effectively. Strategic recommendations include enhancing security headers, updating JavaScript libraries, and publishing explicit security policies and incident response procedures.

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. 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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

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

Ostravská univerzita occupies a significant position in the regional higher education market in the Czech Republic. Its competitive advantages include a broad portfolio of faculties, active research projects, international partnerships, and comprehensive student services. The business model is focused on education, research, and community engagement, with revenue streams likely from government funding, tuition fees, research grants, and continuing education programs. The university targets students, researchers, academic staff, and external partners. Growth indicators include active strategic projects and international cooperation. The partnership ecosystem includes multiple faculties and research institutes under the osu.cz domain, as well as external academic and technology partners.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, Content Security Policy to upgrade insecure requests, and cookie consent mechanisms. No exposed credentials or sensitive data were found. The use of an older jQuery version (1.12.2) is a minor vulnerability risk and should be updated. Security headers like X-Frame-Options and HSTS are missing and recommended for implementation. There is no visible security or incident response policy published, which is a gap in compliance and readiness. Overall, the site is secure but could improve by adopting additional best practices and transparency in security governance.

Recommendations

  1. Implement additional security headers such as X-Frame-Options, X-Content-Type-Options, Referrer-Policy, and HSTS.
  2. Update JavaScript libraries, especially jQuery, to the latest stable versions to mitigate known vulnerabilities.
  3. Publish a clear security policy and incident response plan on the website to enhance transparency and preparedness.
  4. Improve accessibility features to meet higher compliance standards and enhance user experience for all users.
  5. Regularly audit and monitor website security and privacy compliance to maintain high standards and trust.

Technical notes

Notes

The website uses a classic web technology stack with jQuery 1.12.2 and jQuery UI 1.11.4, Lightbox for image display, and FontAwesome for icons. The site is structured with responsive CSS stylesheets targeting different screen sizes, indicating good mobile optimization. SEO is supported by meta tags, Open Graph tags, and canonical links. Performance is moderate, with no obvious heavy scripts or slow-loading elements. The site lacks a modern CMS indication and could benefit from modernization to improve maintainability and security. Hosting provider details are not evident from the content. Overall, the technical infrastructure supports the university's needs but has opportunities for modernization and security enhancements.
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.
