75/100

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

Vinný sklep U Mostu is a small hospitality business based in Ostrava, Czech Republic, specializing in wine sales and tastings. The website presents a local wine shop and bar offering a wide selection of wines from Moravia and international sources, including services such as wine menus, degustations, and reservations. The business targets mature wine consumers and local visitors seeking quality wine experiences. Technically, the website uses a variety of JavaScript libraries and plugins, including jQuery, Bootstrap modal, and Nivo Slider, hosted on Banan.cz with a CMS platform called Web Bez starosti. The site is moderately optimized for mobile and accessibility but lacks advanced SEO and structured data. Security posture is adequate with HTTPS and cookie consent but lacks security headers and detailed policies. WHOIS data is unavailable due to privacy protection, which is typical for small businesses and does not raise immediate concerns. Overall, the website is functional, trustworthy, and serves its business purpose effectively.

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

  • Security headers: did not complete in this scan.
  • GDPR outside view: did not complete in this scan.
  • 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 focusing on wine retail and tasting services. It leverages a local market presence in Ostrava with a diverse wine portfolio sourced domestically and internationally. The business model combines direct sales with experiential offerings like wine tastings and events. Contact channels are clearly provided, including email and phone, and social media engagement is maintained via Facebook. The website's partnership with Banan.cz for hosting and design indicates reliance on specialized local service providers. Growth potential may be limited by the small scale and local focus but benefits from a niche market position. No evidence of complex partnerships or subsidiaries was found.

Security posture

The website demonstrates a basic to moderate security posture. HTTPS is enforced, and a cookie consent mechanism is implemented, indicating awareness of privacy regulations. However, the absence of security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options reduces protection against common web attacks. No incident response or security policy information is provided, which limits transparency and preparedness. No vulnerabilities or exposed sensitive data were detected in the HTML content. The use of third-party libraries requires ongoing maintenance to mitigate risks. Overall, the security posture is adequate for a small hospitality business but could be improved to enhance resilience and compliance.

Recommendations

  1. Implement HTTP security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen defense against common web attacks.
  2. Enhance mobile responsiveness and accessibility to improve user experience across devices and for users with disabilities.
  3. Publish a detailed privacy policy and security policy page to increase transparency and demonstrate compliance with GDPR and other regulations.
  4. Establish an incident response contact or security email to facilitate vulnerability reporting and improve security posture.
  5. Regularly update all third-party libraries and plugins to mitigate risks from known vulnerabilities.

Technical notes

Notes

The website is built on a CMS platform called Web Bez starosti, hosted by Banan.cz, and uses a combination of JavaScript libraries including jQuery, Bootstrap modal, Nivo Slider, and nanogallery2 for UI components and galleries. Google Fonts and Material Design Icons are used for typography and icons. The site loads multiple external scripts and stylesheets, some asynchronously, which helps performance. The HTML structure is valid and includes meta tags for viewport and Open Graph for social sharing. However, no JSON-LD structured data is present, limiting SEO potential. Mobile optimization is basic with responsive classes but could be improved. Accessibility features are minimal. Performance is moderate with room for optimization. No CMS-specific security plugins or frameworks were detected.
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.
