Security report for aco.shop

ACO · E-commerce · Germany

Low risk. 3 critical or high findings in Security headers and SSL/TLS.

Security score

80/100

Risk levelLow

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

ACO operates a professional e-commerce platform specializing in construction and drainage products targeted at both private and commercial customers in Germany. The website is built on Magento, leveraging modern web technologies such as RequireJS and jQuery, and integrates performance and analytics tools like New Relic and Google Tag Manager. The site demonstrates good technical maturity with HTTPS enforcement, security headers, and GDPR-compliant cookie consent mechanisms. However, the absence of detailed WHOIS registrant information and direct contact details on the homepage slightly detracts from overall trustworthiness. Security posture is solid with no evident vulnerabilities or exposed sensitive data. Strategic recommendations include enhancing transparency by publishing a security policy, incident response contacts, and improving accessibility features to further strengthen compliance and user 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

3 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 Strict-Transport-Security header

      Forces HTTPS connections

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

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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. 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

ACO is positioned as a significant player in the construction and drainage product market, offering a wide range of products through its online shop. The business model focuses on direct e-commerce sales supported by detailed product categorization and customer service links. The company targets both private homeowners and commercial construction sectors, indicating a broad market reach. The website's integration with marketing and analytics tools suggests active digital marketing efforts. The lack of visible contact information on the homepage may indicate a preference for online self-service or contact via other channels. The company maintains GDPR compliance and transparent cookie management, aligning with European data protection standards.

Security posture

The website exhibits a mature security posture with HTTPS enforced and multiple security headers implemented, reducing risks from common web attacks. The presence of a cookie consent banner and privacy policy indicates compliance with GDPR. No security.txt or vulnerability disclosure policy was found, which could improve transparency and incident handling. The absence of direct incident response contacts or security policy pages is a gap in the security maturity. No vulnerable or outdated libraries were detected in the scripts loaded. Overall, the site follows best practices but could enhance its security culture by publishing more explicit security governance information.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and compliance.
  2. Implement a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  3. Provide clear incident response contact information, such as a security@ or abuse@ email address.
  4. Enhance website accessibility to meet higher standards for users with disabilities.
  5. Regularly audit and update third-party libraries and dependencies to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built on the Magento e-commerce platform, utilizing RequireJS for module loading and jQuery for DOM manipulation. It integrates New Relic Browser monitoring for performance and error tracking, and Google Tag Manager for analytics and marketing tags. The site uses a consent management platform (consentmanager.net) to handle GDPR cookie compliance. The HTML structure is well-formed with appropriate meta tags for SEO and viewport settings for mobile responsiveness. Performance is moderate with multiple CSS and JS assets loaded asynchronously. The site is mobile-optimized and includes accessibility features, though these could be improved. No critical technical debt or deprecated technologies were identified, indicating a modern and maintainable infrastructure.
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.
