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

The website www.co2-ampelshop.de is an e-commerce platform operated by come2print eK, specializing in CO2 measuring devices targeted primarily at schools, kindergartens, and municipal institutions in Germany. The business has been established since at least 2013 and positions itself as a niche provider in the education sector for indoor air quality monitoring solutions. The site offers clear product information, legal pages, and customer contact options, reflecting a professional and focused business model. Technically, the website is built on WordPress with WooCommerce, utilizing common plugins such as Rank Math SEO and Contact Form 7. The site is moderately optimized for performance and mobile use, with good SEO practices including structured data. Hosting is provided via rzone.de, and the site uses HTTPS, though lacks advanced security headers and cookie consent mechanisms. From a security perspective, the site demonstrates basic best practices such as HTTPS and nonce tokens in forms but lacks published security policies, incident response contacts, and cookie consent banners, which are important for GDPR compliance. No critical vulnerabilities or malicious content were detected. The WHOIS data aligns well with the business claims, indicating legitimacy and consistency. Overall, the website presents a trustworthy and professional front for a small specialized e-commerce business. Improvements in security headers, privacy compliance (cookie consent), and incident response transparency would enhance the security posture and regulatory compliance.

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 Cookie Policy found

      GDPR requires clear information about cookie usage

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

  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 Strict-Transport-Security header

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

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 come2print eK operates co2-ampelshop.de as a specialized retailer for CO2 measuring devices aimed at educational and municipal sectors. The business model is direct e-commerce sales with a focus on niche products that support health and safety in schools and kindergartens. The market positioning is strong within this niche in Germany, supported by clear product offerings and customer support. The partnership with kommunalbedarf24.de indicates a broader ecosystem in municipal supplies. Revenue streams are primarily product sales, with potential for growth in related safety and monitoring equipment. The website content and structure support a professional image, targeting institutional buyers rather than consumers. The company maintains clear legal and contact information, enhancing credibility.

Security posture

The website has a basic security posture with HTTPS enabled and secure form handling via nonce tokens. However, it lacks important security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security, which are recommended to mitigate common web attacks. There is no visible security or incident response policy, nor dedicated contact channels for security issues. Cookie consent mechanisms are absent, which is a compliance gap under GDPR. No known vulnerabilities or exposed sensitive data were found in the HTML content. Overall, the security maturity is moderate but could be significantly improved by implementing recommended headers, publishing security policies, and adding cookie consent.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  2. Add a GDPR-compliant cookie consent banner and mechanism to inform users and obtain consent.
  3. Publish a clear security policy and incident response contact information on the website.
  4. Regularly audit and update all WordPress plugins and themes to minimize vulnerability risks.
  5. Enhance accessibility features to improve compliance and user experience for all visitors.

Technical notes

Notes

The website is built on a WordPress CMS platform with WooCommerce for e-commerce functionality. It uses common JavaScript libraries such as jQuery and Flickity for UI components like sliders. SEO is enhanced with the Rank Math plugin and structured data in JSON-LD format is properly implemented for organization and webpage metadata. Hosting is via rzone.de, indicated by the nameservers. The site is mobile responsive and has a moderate performance profile. There is some technical debt in the absence of security headers and cookie consent mechanisms. The site uses standard WordPress themes and plugins, which require ongoing maintenance to ensure security and performance.
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.
