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

Potrefená Husa Zlín is a local restaurant in Zlín, Czech Republic, specializing in traditional Czech beer culture and quality dining experiences. The website presents a professional and user-friendly interface with clear contact details and online reservation options, targeting local customers including families and couples. The business operates primarily in the hospitality sector with a focus on food and beverage services. Technically, the website is built on WordPress with common plugins and libraries, offering moderate performance and good mobile optimization. Security posture is adequate with HTTPS enabled but lacks advanced security headers and privacy compliance features. The absence of WHOIS data for the domain reduces trustworthiness from a domain registration perspective. Overall, the site is functional and professional but would benefit from enhanced privacy policies and security practices.

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

12 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

  2. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

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 · found on this site
  • 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 positions itself as a traditional yet welcoming venue emphasizing Czech beer culture and quality food. Its business model includes dine-in services with online reservation capabilities. The website content and structure suggest a small-sized local business with consistent branding and moderate market presence. Partnerships with local design and IT service providers are evident. The lack of detailed company registration or certification information limits deeper business intelligence insights. The target market is local residents and visitors seeking authentic dining experiences in Zlín.

Security posture

The website uses HTTPS, which is a fundamental security measure. However, no security headers such as Content-Security-Policy or X-Frame-Options were detected, which could improve protection against common web attacks. There is no visible privacy or cookie policy, indicating potential GDPR compliance gaps. No incident response or vulnerability disclosure information is provided. The site does not appear to use extensive tracking or analytics, reducing privacy risks but also limiting data-driven security insights. Overall, the security posture is basic and could be improved with standard best practices and compliance documentation.

Recommendations

  1. Implement and publish a comprehensive privacy policy and cookie consent mechanism to improve GDPR compliance.
  2. Add security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance web security.
  3. Obtain and maintain accurate WHOIS domain registration data to improve domain trustworthiness.
  4. Include incident response and vulnerability disclosure information to demonstrate security maturity.
  5. Regularly update WordPress core, themes, and plugins to mitigate vulnerabilities and maintain performance.

Key observations

  1. Website is a professionally designed WordPress site for a local restaurant in Zlín, Czech Republic.
  2. No WHOIS data available, which is unusual and reduces domain trust.
  3. No privacy or cookie policies found, which is a compliance gap.
  4. Contact information is clearly provided including phone, email, and physical address.
  5. No security headers detected in the provided data; HTTPS is used.
  6. No evidence of tracking or analytics services detected in the HTML content.
  7. No forms with personal data collection found except Contact Form 7 plugin scripts, but no visible form fields on homepage.
  8. No social media links explicitly found in the HTML content.
  9. Content is safe but includes alcohol-related services, so rated as 'questionable' for mature audience.
Technical notes

Notes

The website is built on WordPress 6.8.2 with a child theme of GeneratePress and uses several popular plugins including Contact Form 7, Simple Lightbox, Popup Maker, and Owl Carousel. It loads Google Fonts and jQuery libraries from trusted CDNs. The site is mobile responsive and uses modern CSS variables and grid layouts. Performance is moderate with no explicit performance optimization scripts detected. Accessibility features are basic, with skip links and some ARIA attributes present. SEO optimization is basic with meta tags and canonical links but lacks advanced structured data or Open Graph metadata. Hosting provider details are not discernible from the HTML 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.
