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.

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

    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

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 company targets gastronomy enthusiasts, families, and corporate clients seeking team-building activities. Its business model revolves around service delivery via cooking courses and event hosting, supplemented by gift voucher sales. The domain age and registration data align with the business timeline, reinforcing credibility. Partnerships with local restaurants and related e-shops indicate a collaborative ecosystem. The website content and calendar demonstrate active engagement and a broad course offering, signaling growth and market presence.

Security posture

The site employs HTTPS with a good SSL configuration and uses Google reCAPTCHA v3 to protect forms. Cookie consent is implemented with opt-in, supporting GDPR compliance. However, explicit security headers like Content-Security-Policy and X-Frame-Options are not evident, which could enhance protection against common web attacks. No incident response or security policy information is published, which is a gap in transparency. Lazy loading image errors may affect user experience and should be addressed. Overall, the security posture is moderate to good but can be improved with additional headers and policies.

Recommendations

  1. Implement and enforce security headers such as CSP, X-Frame-Options, and X-Content-Type-Options.
  2. Fix broken lazy loading images to improve user experience and reduce potential security risks.
  3. Publish a clear security policy and incident response contact information to enhance transparency.
  4. Regularly update WordPress core and plugins to mitigate vulnerabilities.
  5. Consider a security audit to identify and remediate any hidden vulnerabilities.

Notes

The website is built on WordPress with WooCommerce, leveraging popular plugins like Yoast SEO, WP Rocket for caching and performance, and Complianz for GDPR compliance. It uses FullCalendar for event scheduling and integrates Google Fonts, Google Tag Manager, Facebook Pixel, and Microsoft Clarity for analytics and marketing. The site shows good mobile optimization and SEO practices. Hosting is via a Czech registrar with nameservers at websupport.sk, indicating local hosting. Performance is moderate with some lazy loading issues. Accessibility is basic but could be enhanced. Overall, the technical infrastructure is modern and suitable for the business needs.
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.
