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

Bucher Denwel, spol. s r.o. is a Czech-based company specializing in innovative brewing technologies and engineering solutions for industries such as brewing, pharmaceuticals, chemicals, and energy. The company offers turnkey projects, specialized equipment, and process analytical technologies, positioning itself as a medium-sized B2B industrial technology provider with a professional online presence and ISO certification. The website is well-structured, professionally designed, and targets industrial clients seeking advanced process solutions. Technically, the site uses legacy JavaScript libraries and a CMS called WebArchitect, with moderate performance and basic mobile optimization. Security posture is moderate with cookie consent implemented but lacks modern security headers and updated libraries. WHOIS data is missing, which reduces domain trustworthiness, but the website content and branding indicate a legitimate business. Overall, the site scores well on content quality and business credibility but should improve technical and security aspects.

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

7 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

    • High

      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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

    • High

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 operates in specialized industrial sectors including brewing, pharmaceuticals, chemicals, and energy, offering engineering and manufacturing services. Its market positioning is that of an established technology provider with international reach, supported by ISO certification and professional marketing efforts. The business model is B2B focused, targeting industrial clients requiring customized process solutions. The website indicates active marketing through SEO and social media channels, but lacks direct contact details on the homepage. Growth indicators include recent news about acquisitions and participation in major industry conferences. Partnerships with web development and marketing firms are evident. The company maintains a consistent brand image and professional content, supporting a medium-sized enterprise profile.

Security posture

The website employs HTTPS and a cookie consent mechanism with opt-in, indicating awareness of privacy compliance. However, it lacks visible security headers such as Content Security Policy, HSTS, or X-Frame-Options, which are recommended for enhanced protection. The use of an outdated jQuery version (1.6) presents potential vulnerabilities. No incident response or security contact information is publicly available, and no vulnerability disclosure or security.txt files were found. The absence of WHOIS data raises concerns about domain registration legitimacy. Overall, the security maturity is moderate but could be significantly improved by updating libraries, implementing security headers, and publishing clear security policies.

Recommendations

  1. Update JavaScript libraries, especially jQuery, to the latest secure versions to mitigate known vulnerabilities.
  2. Implement and configure essential security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options.
  3. Publish explicit security policies and incident response contact information to improve transparency and readiness.
  4. Verify and update WHOIS domain registration information to enhance trust and legitimacy.
  5. Improve mobile responsiveness and accessibility to enhance user experience and compliance.

Technical notes

Notes

The website is built using the WebArchitect CMS platform and includes JavaScript libraries such as jQuery 1.6 and SWFObject, along with Google Maps API v3.9. The site uses multiple CSS stylesheets for layout and print media. Performance is moderate with some legacy technologies that could be modernized. The site includes a cookie consent banner with opt-in functionality, indicating some privacy compliance. SEO is supported by meta tags and structured navigation menus. Accessibility features are basic, including skip links. The site lacks modern security headers and uses outdated JavaScript libraries, which pose technical risks. Hosting provider details are not disclosed. Overall, the technical infrastructure is functional but would benefit from modernization and security hardening.
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.
