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

Hotel Kleis is a small hospitality business located in the Czech Republic, uniquely positioned within the historic Cvikov Brewery site. The hotel offers modern accommodation and event hosting services, targeting corporate clients, families, and groups seeking a distinctive mountain and brewery experience. The website is professionally designed with multilingual support and clear navigation, reflecting a mature digital presence. Technically, the site uses modern web technologies and is hosted by a reputable Czech provider, Websupport. Security posture is adequate with HTTPS enabled, but lacks advanced security headers and published security policies. Privacy compliance is partial, with a cookie consent mechanism present but no privacy or terms of service pages. Overall, the business appears legitimate and well-positioned in its niche, though improvements in compliance and security transparency are recommended.

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

9 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

      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

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 operates in the hospitality sector with a niche focus on brewery-related tourism and accommodation. Its business model integrates lodging with brewery and restaurant services, creating a unique value proposition. The market positioning is specialized, appealing to both leisure and corporate segments. The presence of partner domains related to the brewery and restaurant indicates a collaborative ecosystem. The business is small-sized, founded around 2018, with no visible parent or subsidiary companies. Growth potential lies in leveraging the unique brewery environment and expanding service packages. The website content and social media presence support brand consistency and customer engagement.

Security posture

The website demonstrates a basic to moderate security maturity level. HTTPS is enforced, ensuring encrypted communications. However, the absence of key security headers such as Content-Security-Policy and X-Frame-Options reduces protection against common web attacks. No incident response or vulnerability disclosure information is published, indicating limited transparency in security management. Privacy compliance is partial, with cookie consent implemented but lacking comprehensive privacy policies. No forms are present on the main page, reducing immediate attack surface, but reservation and contact forms on other pages should be reviewed for security. Overall, the security posture is adequate for a small hospitality business but could be enhanced to meet higher compliance standards and customer trust expectations.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service to improve compliance and user trust.
  2. Implement and configure security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options.
  3. Establish and publish an incident response policy or security contact to enhance transparency and readiness.
  4. Conduct a security review of all forms on the website to ensure secure data handling and input validation.
  5. Enhance SEO and accessibility features to improve website reach and usability.

Technical notes

Notes

The website uses modern HTML5, CSS, and JavaScript technologies, including the Splide.js library for carousel functionality and lazy loading for images to optimize performance. The hosting is provided by Websupport, a known Czech hosting provider, which supports reliability. The site is mobile optimized with responsive design and supports multiple languages (Czech, English, German). However, no CMS or major frameworks are explicitly detected, suggesting a custom or lightweight solution. Performance is moderate with room for improvement in SEO metadata completeness and accessibility compliance. No analytics or tracking scripts were detected in the provided HTML, indicating minimal user tracking. Overall, the technical infrastructure is solid for a small hospitality website but could benefit from enhanced SEO and accessibility improvements.
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.
