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

Contentserver24, operated by atrego GmbH, is a specialized provider of web content and digital solutions tailored for the energy sector, particularly fuel and mineral oil traders. The company offers a comprehensive suite of services including online shops, newsletters, daily pricing updates, and website development, positioning itself as a niche B2B service provider in Germany. The website reflects a professional and consistent brand image with clear navigation and relevant content for its target audience. Technically, the website employs modern frameworks such as Bootstrap 5 and jQuery, integrates Google Analytics with IP anonymization, and uses reCAPTCHA for form security. The site is mobile-optimized and demonstrates good SEO practices. However, some security headers are missing, and no explicit security or incident response policies are published, indicating room for improvement in security posture. The security evaluation shows a good baseline with HTTPS enforced and anti-spam measures in place, but lacks advanced security headers and formal incident response contacts. Privacy compliance is strong, with a clear GDPR-compliant privacy policy and cookie consent mechanism. WHOIS data is minimal, limiting full trust verification, but the website's professional presentation and business consistency support legitimacy. Overall, Contentserver24 presents a trustworthy and professional digital presence with solid technical foundations and privacy compliance, suitable for its specialized market. Strategic enhancements in security policies and domain transparency would further strengthen its risk profile.

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

8 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

      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 X-Frame-Options header

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

Contentserver24 operates in the energy sector, focusing on digital content solutions for fuel and mineral oil traders. Its competitive advantage lies in industry-specific modules and a comprehensive service offering that includes app development, social media management, and SEO. The business model is B2B, targeting energy traders who require up-to-date web content without investing internal resources. Revenue streams likely include subscription or licensing fees for content modules and custom development projects. The company maintains partnerships with related service providers, enhancing its ecosystem. Growth indicators include a long-standing presence since 2001 and a diversified service portfolio. Strategic observations suggest a focus on niche specialization and digital transformation support for energy businesses.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and use of Google Analytics with IP anonymization, indicating privacy awareness. Forms incorporate reCAPTCHA and honeypot fields to mitigate spam. However, the absence of key security headers such as Content Security Policy, HSTS, and X-Frame-Options reduces defense-in-depth. No published security policy or incident response contacts limit transparency and readiness. GDPR compliance is evident, but no vulnerability disclosure or security.txt files are present. No visible vulnerabilities or exposed sensitive data were detected. Overall, the security posture is adequate for the business type but would benefit from enhanced header implementation, formalized security policies, and incident response mechanisms.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, X-Frame-Options, and X-XSS-Protection to strengthen browser security.
  2. Publish a clear security policy and incident response contact information to improve transparency and preparedness.
  3. Regularly audit and update third-party libraries and dependencies to mitigate potential vulnerabilities.
  4. Enhance website accessibility features to improve compliance and user experience for all users.
  5. Consider establishing a vulnerability disclosure program or security.txt file to encourage responsible reporting.

Technical notes

Notes

The website is built on a custom CMS (Contentserver24 CMS) utilizing Bootstrap 5 for responsive design and jQuery for client-side scripting. Google Analytics is integrated with IP anonymization for privacy. The site loads external CSS and JS resources from both the main domain and subdomains (my.contentserver24.de, secure.contentserver24.de). Performance is moderate with asynchronous script loading and deferred analytics. Mobile optimization is good with responsive layouts and viewport meta tags. SEO is supported by canonical links, meta descriptions, and keywords. Accessibility is basic with room for improvement in ARIA roles and keyboard navigation. Hosting provider details are not explicitly identified. Overall, the technical infrastructure is modern and functional but could benefit from enhanced accessibility and security header implementation.
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.
