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

  2. Security headers

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 institute holds a strong market position as one of the largest holders of language licenses in Slovakia, accredited by the Ministry of Education. Its business model focuses on language education services, including individual and corporate courses, exam preparation, and authorized testing centers. The presence of partner logos and subdomains for e-records indicates a mature partnership ecosystem. The target audience is broad, covering youth and adults, with growth potential in corporate training. The website content and structure support a professional educational service with clear trust signals.

Security posture

The website employs HTTPS with a valid SSL configuration and secure login forms using nonces, indicating good baseline security practices. However, the absence of security headers such as Content-Security-Policy and X-Frame-Options reduces the overall security posture. No vulnerabilities or exposed sensitive data were detected in the HTML content. The lack of a dedicated security policy or incident response contact limits transparency and readiness for security incidents. GDPR compliance is partial, with a privacy policy present but no cookie consent mechanism. Overall, the security maturity is moderate with room for improvement.

Recommendations

  1. Implement standard security headers (CSP, X-Frame-Options, X-XSS-Protection) to enhance protection against common web attacks.
  2. Add a cookie consent banner/mechanism to comply fully with GDPR requirements.
  3. Publish a security policy and incident response contact information to improve transparency and preparedness.
  4. Regularly audit and update WordPress plugins and themes to mitigate vulnerabilities.
  5. Enhance accessibility features and SEO optimization for better user experience and search ranking.

Technical notes

Notes

The website is built on a WordPress CMS platform using the Flatsome theme and WooCommerce for e-commerce capabilities. It leverages jQuery and jQuery UI libraries, along with plugins such as Easy Accordion, Contact Form 7, and Back In Stock Notifier. The site uses Google Fonts and CDN services for performance optimization. The technical implementation is modern but could benefit from improved accessibility and SEO practices. Performance is moderate, with prefetching and deferred script loading observed. Hosting provider details are not explicitly identified from the content.
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.
