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

Vysoká škola Sting, o.p.s. is a private higher education institution based in the Czech Republic specializing in accounting, taxation, and financial management education. The website presents a professional and comprehensive digital presence with detailed program offerings, news, testimonials, and partner collaborations. The institution targets students and professionals seeking practical and career-oriented education in finance and economics. The site is built on Drupal 11, employs modern web technologies, and is mobile-optimized with good accessibility and SEO practices. Privacy and cookie policies are implemented with GDPR compliance, and the site uses Google Tag Manager for analytics with user consent mechanisms in place. However, the WHOIS data for the domain is missing, which raises concerns about domain registration transparency and legitimacy. Despite this, the website content and branding are consistent and trustworthy, supported by certifications and regional awards.

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

    • 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

  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 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 institution holds a strong market position as a private university with the longest tradition in Brno and expanding presence in Prague. Its business model focuses on providing bachelor and professional education with a practical approach, supported by partnerships with firms and a network of related educational entities such as Newton University. The website highlights multiple collaborations and certifications, indicating a well-established ecosystem. Revenue streams likely include tuition fees and professional courses. The target customer segment includes Czech and international students interested in finance and accounting careers. Growth indicators include recent news about relocation and events. The partnership ecosystem is robust, involving accounting firms, business accelerators, and technology parks.

Security posture

The website enforces HTTPS and implements cookie consent mechanisms, reflecting a baseline security posture. However, no explicit security headers were detected in the HTML source, which could be improved to enhance protection against common web attacks. There is no visible incident response or vulnerability disclosure information, which is a gap in security transparency. The absence of WHOIS data is a notable concern for domain legitimacy and trust. No vulnerabilities or exposed sensitive data were found in the content. Overall, the security posture is moderate but could benefit from enhanced headers, published security policies, and domain registration transparency.

Recommendations

  1. Implement and enforce security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to improve web security.
  2. Publish a security.txt file or a dedicated vulnerability disclosure policy to facilitate responsible reporting of security issues.
  3. Verify and update WHOIS domain registration information to ensure transparency and trustworthiness.
  4. Regularly audit third-party scripts and dependencies to mitigate risks from vulnerable libraries.
  5. Enhance incident response readiness by providing clear contact channels for security incidents and abuse reports.

Technical notes

Notes

The website is built on Drupal 11, a modern and widely used CMS, supported by jQuery and Swiper.js for UI components. Google Tag Manager is used for analytics and marketing tags, with consent-based activation. The site is mobile-optimized and accessible, with good SEO metadata including Open Graph and Twitter cards. Performance is moderate, with optimized images and responsive design. No hosting provider details were identified from the content. The technical stack is modern and appropriate for an educational institution, though improvements in security headers and domain registration transparency are recommended to reduce technical risks.
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.
