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

Städtereinigung Gerke GmbH is a well-established regional service provider specializing in municipal and industrial waste management and sanitation services in Tönisvorst, Willich, and surrounding areas in Germany. With over 60 years of history, the company offers a broad range of services including hazardous waste disposal, sanitary rentals, and container rentals through an online shop. The website reflects a professional and consistent brand image targeting local businesses, municipalities, and citizens. Technically, the site is built on modern frameworks such as Next.js and React, hosted on Vodafone infrastructure, and incorporates consent management and analytics tools like Usercentrics and Google Tag Manager. Security posture is solid with HTTPS and basic security best practices, though explicit security headers and incident response policies are not published. Overall, the site is accessible, well-structured, and compliant with GDPR, but could improve transparency on security and incident response. Strategic recommendations include enhancing security headers, publishing a security policy, and adding vulnerability disclosure mechanisms.

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

6 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 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

  2. 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

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 holds a strong regional market position as a trusted partner for municipal waste and sanitation services, leveraging decades of experience. Its business model focuses on providing tailored waste disposal solutions for commercial and industrial clients, alongside citizen services such as recycling centers and container rentals. The partnership ecosystem includes related domains for electronic waste notification and container sales, indicating integrated service offerings. The website supports growth through an online container shop and career portal, signaling operational maturity and customer engagement. The absence of direct email contacts suggests a preference for controlled communication channels, possibly to reduce spam and improve service quality.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, use of a reputable consent management platform, and no visible exposure of sensitive data or vulnerable libraries. However, the lack of explicit security headers like X-Frame-Options and a published security policy or incident response contacts indicates room for improvement. No vulnerability disclosure or security.txt file is present, which could hinder responsible vulnerability reporting. The site’s security score is good but not excellent, reflecting solid baseline protections but missing advanced transparency and communication features. The company should consider formalizing its security policies and incident response readiness to enhance trust and compliance.

Recommendations

  1. Implement and verify comprehensive security headers including X-Frame-Options, X-Content-Type-Options, and Referrer-Policy.
  2. Publish a clear security policy and incident response contact information on the website.
  3. Add a security.txt file to facilitate vulnerability disclosure and responsible reporting.
  4. Regularly audit and update third-party libraries to prevent vulnerabilities.
  5. Enhance accessibility features and provide more detailed contact information including physical address and email contacts.

Technical notes

Notes

The website is built using modern web technologies such as React and Next.js, ensuring good performance and mobile responsiveness. Hosting is provided by Vodafone IP, indicating reliable infrastructure. The integration of Usercentrics for consent management and Google Tag Manager for analytics reflects compliance with privacy regulations and data-driven marketing. The site’s SEO is well-optimized with appropriate meta tags and Open Graph data. However, accessibility is rated basic, suggesting potential improvements in ARIA roles and keyboard navigation. Performance is moderate, likely due to rich media content such as videos and images. Overall, the technical implementation supports a professional user experience but could benefit from enhanced accessibility and security header configurations.
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.
