Risk levelLow

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

Modrý dveře is a small hospitality business operating a restaurant in České Budějovice, Czech Republic, specializing in grilled food and tank beer. The website presents a professional and well-structured digital presence with clear business information, reservation capabilities, and active social media links. The technical infrastructure is based on WordPress with modern libraries and tracking tools such as Google Analytics and Tag Manager. Privacy and cookie policies are implemented with user consent mechanisms, indicating a basic level of GDPR compliance. Security posture is good with HTTPS enforced, but lacks advanced security headers and explicit security policies. The absence of WHOIS data limits domain trust verification, suggesting the need for further domain legitimacy checks. Overall, the website is functional, trustworthy, and suitable for its business purpose.

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

2 findings rated critical or high. Fix these first.

  1. 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.

    • High

      No DMARC record found

      DMARC provides email authentication and reporting

      What to do: Add DMARC record: "v=DMARC1; p=none; rua=mailto:dmarc@yourdomain.com"

  2. 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 company Cultura, s.r.o. operates the Modrý dveře restaurant, targeting local customers and visitors interested in quality Czech beer and grilled cuisine. The business model focuses on dine-in services with an emphasis on unique grilling techniques and fresh ingredients. The website supports customer engagement through online reservations and newsletter subscriptions. The partnership with www.cecovka.cz indicates a local network of hospitality businesses. The digital presence is optimized for SEO and mobile users, supporting growth and customer retention. No direct revenue streams beyond restaurant services are evident from the website content.

Security posture

The website demonstrates a moderate to good security posture with HTTPS enabled and cookie consent implemented. However, no advanced security headers were detected, and there is no visible security policy or incident response contact information. The forms collect personal data securely via HTTPS but lack visible anti-CSRF tokens or CAPTCHA mechanisms. No vulnerability disclosures or security.txt files are present, which could improve transparency and security culture. The use of third-party scripts like Google Analytics introduces moderate tracking but is common in hospitality websites. Overall, the security posture is adequate but could benefit from enhancements in headers, policies, and incident response readiness.

Recommendations

  1. Implement security headers such as Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to enhance protection against common web attacks.
  2. Publish a dedicated security policy page and provide incident response contact information to improve transparency and trust.
  3. Add a security.txt file to facilitate responsible vulnerability disclosure and improve security culture.
  4. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.
  5. Enhance accessibility features to comply with standards and improve user experience for all visitors.

Technical notes

Notes

The website is built on WordPress CMS with a modern theme and uses jQuery and FancyApps UI for UI components. Google Fonts and CDN services are used for performance optimization. The site loads asynchronously Google Analytics and Tag Manager scripts for tracking. The presence of Yoast SEO plugin indicates attention to SEO best practices. The site is mobile optimized with responsive design and viewport meta tags. Performance is moderate with some large images but overall good structure. No hosting provider information is directly available. The site uses cookie-bar for consent management. Technical debt appears low, but security header implementation is missing. The site could improve accessibility and performance by optimizing images and adding ARIA attributes.
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.
