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

U Tonka is a small hospitality business operating a restaurant and bar in Vizovice, Czech Republic. The website presents a clear overview of their food and beverage offerings, accommodation services, and event catering. The business targets local residents and visitors interested in traditional Czech cuisine and regional specialties. The site is professionally designed with good navigation and content relevance, though it lacks comprehensive privacy and cookie policies. Technically, the site uses basic web technologies and Google Analytics for tracking but lacks advanced security headers and visible HTTPS confirmation in the provided data. The absence of WHOIS data reduces domain trustworthiness, but the website content and contact phone number support legitimacy. Overall, the site is functional and informative but would benefit from improved security and privacy compliance.

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

10 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. 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.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  3. 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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';…

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 business operates in the hospitality sector with a focus on restaurant dining and accommodation. It leverages local cultural and culinary traditions to attract customers. The acceptance of multiple meal vouchers indicates integration with local payment systems. Partnerships with local businesses and a web design company suggest a small but connected operation. The business model is service-oriented with revenue streams from food, beverages, lodging, and event catering. Growth potential may be limited by local market size but supported by cultural tourism in Vizovice.

Security posture

The website demonstrates a basic security posture with no visible forms collecting sensitive data and no exposed credentials. However, the lack of HTTPS confirmation, security headers, and privacy policies indicates gaps in security best practices and compliance. The use of Google Analytics introduces moderate user tracking without clear privacy disclosures. Incident response and vulnerability disclosure mechanisms are absent. Overall, the security maturity is low to moderate, suitable for a small local business but requiring improvements to meet modern standards.

Recommendations

  1. Implement HTTPS with a valid SSL certificate and verify secure configuration.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Publish clear privacy and cookie policies to improve GDPR compliance and user trust.
  4. Provide a company contact email address for general and security-related inquiries.
  5. Consider adding a vulnerability disclosure or security contact page to enhance transparency.

Technical notes

Notes

The website uses standard HTML, CSS, and JavaScript with Google Analytics for tracking. It is built on the WEB realizer CMS platform provided by Syntax Media. The site has a moderate performance profile with basic mobile optimization and accessibility features. SEO is supported by meta tags and structured navigation. There is no evidence of modern JavaScript frameworks or advanced backend technologies. Hosting provider details are not available. The technical stack is sufficient for a small hospitality business but could be modernized for improved performance and security.
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.
