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

big. bechtold-gruppe is a well-established German family-owned service provider specializing in integrated facility, engineering, and security services. Founded in 1981 and employing over 3,000 people, the company offers a broad portfolio including engineering services, facility management, security services, and smart services. Their market position is strong within Germany, targeting businesses and organizations requiring comprehensive building-related services. The website reflects a professional and consistent brand image with clear navigation and detailed service descriptions. Technically, the website is built on WordPress with Elementor, leveraging modern web technologies and privacy-conscious analytics tools like Matomo. The site is mobile-optimized, accessible, and SEO-friendly, indicating a mature digital presence. Security posture is good with HTTPS enforced and no obvious vulnerabilities, though some security headers could be improved. Privacy compliance is well addressed with clear privacy and cookie policies and GDPR adherence. However, the WHOIS data for the domain is missing, which raises concerns about domain registration transparency and legitimacy. This discrepancy between the professional website and missing domain registration data suggests a need for further verification. Overall, the site presents a low risk but would benefit from improved domain registration transparency and enhanced security headers. Strategic recommendations include implementing comprehensive security headers, publishing a security policy and incident response contacts, and verifying domain registration details to enhance trust.

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

5 findings rated critical or high. Fix these first.

  1. 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 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';…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • 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

  3. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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 the facility management and security services sector, offering integrated solutions that combine engineering, facility, and security services under a family-owned business model. Their competitive advantage lies in the synergetic integration of services and a strong regional presence in Germany. Revenue streams likely include long-term service contracts with commercial, public, and industrial clients. The target customer segments are businesses and institutions requiring building-related services. The company maintains an active partnership ecosystem, including a dedicated job portal domain. Growth indicators include a large employee base and diversified service offerings. Strategic observations suggest a focus on digital maturity and customer trust through transparency and comprehensive service portfolios.

Security posture

The website demonstrates a good security maturity level with HTTPS enabled and use of privacy-respecting analytics. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options indicates room for improvement. There is no visible security policy or incident response information, which could impact incident readiness and user trust. Compliance with GDPR is evident through privacy and cookie policies. Overall, the security culture appears professional but could be enhanced by formalizing security policies and improving HTTP header configurations.

Recommendations

  1. Implement and enforce security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  2. Publish a clear security policy and incident response contact information on the website to improve transparency and readiness.
  3. Verify and update domain WHOIS registration details to ensure transparency and enhance domain legitimacy trust.
  4. Regularly audit and update WordPress core, themes, and plugins to prevent vulnerabilities.
  5. Enhance user trust by adding certifications or trust badges related to security and compliance.

Key observations

  1. Website is fully accessible with no blocking or WAF challenges.
  2. Content is comprehensive, professional, and business-focused.
  3. Strong presence of social media and contact information.
  4. Use of modern CMS and analytics tools with privacy considerations.
  5. WHOIS data missing, which reduces trust in domain registration transparency.
Technical notes

Notes

The website is built on WordPress CMS with the Elementor page builder, indicating a modern and flexible infrastructure. It uses jQuery and integrates Matomo and Facebook Pixel for analytics and marketing. The site is mobile-optimized and accessible, with good SEO practices including meta tags and structured data (JSON-LD). Performance is moderate, likely influenced by rich media content such as large images and carousels. Hosting provider details are not explicit. Technical risks include potential outdated plugins or themes if not maintained, and missing security headers. Opportunities exist to improve performance via image optimization and caching strategies.
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.
