ZEM Prague is a small, avant-garde Czech cuisine restaurant located near Wenceslas Square in Prague, blending traditional Czech culinary elements with Japanese Izakaya influences. The business targets food lovers and tourists seeking a unique dining experience. The website is professionally designed using WordPress and Elementor, featuring modern technologies such as WooCommerce for reservations and Mailchimp for newsletter subscriptions. SEO and mobile optimization are well implemented, enhancing user experience and discoverability. Security posture is adequate with HTTPS enabled and clientTransferProhibited domain status, but could be improved by enabling DNSSEC and adding security headers and policies.

Overall, the website and domain registration details align well with the business profile, indicating a trustworthy and credible online presence.

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. 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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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';…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • 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

  3. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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 restaurant operates in the hospitality sector with a niche market position focusing on innovative Czech bistronomy. Its business model includes à la carte dining, business lunches, brunches, event hosting, and gift vouchers. The company leverages partnerships with hospitality platforms such as Hyatt and hotel-info.co for menu and booking integrations. The website's content and marketing tools indicate a focus on customer engagement through newsletters and online reservations. The domain age and registration details are consistent with the business founding date, supporting credibility. No subsidiaries or parent companies are identified, suggesting an independent operation.

Security posture

The website employs HTTPS and has a clientTransferProhibited domain status, which protects against unauthorized domain transfers. However, DNSSEC is not enabled, and advanced HTTP security headers are not detected, which could expose the site to certain DNS and web-based attacks. No security.txt or vulnerability disclosure policies are present, limiting transparency for security researchers. The cookie consent banner complies with GDPR, indicating awareness of privacy regulations. No incident response or security contact information is provided, which is a gap in security readiness. Overall, the security posture is moderate but can be enhanced with additional measures.

Recommendations

  1. Enable DNSSEC to secure DNS queries and prevent spoofing.
  2. Implement and publish a security.txt file to facilitate vulnerability reporting.
  3. Add HTTP security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Provide explicit incident response contact information on the website.
  5. Maintain and regularly update privacy and security policies to ensure ongoing compliance and trust.

Technical notes

Notes

The website is built on WordPress CMS with Elementor page builder and WooCommerce for e-commerce capabilities. It integrates third-party services including Google Tag Manager for analytics, Mailchimp for email marketing, and YouTube for video content. The site uses modern fonts and responsive design techniques, ensuring good mobile optimization. Performance is moderate, with some heavy images and video backgrounds that may impact load times. SEO is enhanced by Yoast SEO plugin and structured data in JSON-LD format. Accessibility is basic but could be improved with more ARIA roles and semantic markup. Hosting is via GoDaddy registrar, with no explicit hosting provider identified. Overall, the technical infrastructure is solid but has room for optimization and security hardening.
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.
