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

Wintershall Dea GmbH is a leading independent gas and oil company in Europe, with a strong market position in the energy sector. The company focuses on exploration and production of gas and oil, targeting investors, partners, and customers within the energy industry. The website reflects a professional corporate presence with comprehensive content about the company's history, management, and responsibility. The digital infrastructure is built on Drupal CMS, enhanced with Matomo analytics for user tracking under GDPR-compliant cookie consent mechanisms. The site is mobile-optimized and accessible, with clear navigation and consistent branding. From a security perspective, the website enforces HTTPS and employs cookie consent categories, but lacks explicit security headers and published security policies or incident response contacts. No vulnerabilities or exposed sensitive data were detected in the HTML content. The site integrates multiple marketing and tracking tools including LinkedIn Insight, Google Ads, Meta Pixel, and Twitter tracking, all gated behind user consent. Overall, the security posture is solid but could be improved by adding formal security policies and headers. The domain registration details align well with the company's identity, showing consistency and legitimacy. No WAF or blocking mechanisms interfere with content access, allowing full analysis. The website demonstrates a high level of professionalism and trustworthiness, suitable for its corporate audience and business model.

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

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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. 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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

  3. 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 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';…

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

  • Email security: did not complete in this scan.
  • 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

Wintershall Dea operates as a major player in the European energy market, specializing in gas and oil exploration and production. The company leverages a business model focused on upstream energy services, targeting industrial clients and energy markets. Its competitive advantage lies in its independent status and established legacy, as reflected in the detailed historical content. The website supports business intelligence by providing transparent corporate governance information and compliance details, which enhance investor confidence. The marketing ecosystem includes social media channels and advanced analytics, indicating a mature digital marketing strategy. Growth indicators include recent news about asset transfers and ongoing corporate responsibility initiatives. The absence of direct contact emails or phone numbers on the homepage suggests a controlled communication channel, likely via contact forms or dedicated pages.

Security posture

The website demonstrates a moderate to good security maturity level. HTTPS is enforced, and cookie consent mechanisms comply with GDPR requirements, including detailed categories for strictly necessary, analytics, YouTube, and marketing cookies. The use of Matomo analytics with anonymized IP addresses shows privacy-conscious tracking. However, the absence of explicit security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces the overall security hardening. No vulnerability disclosure or incident response information is published, which could hinder timely reporting and handling of security issues. No exposed credentials or sensitive data were found, and no vulnerable libraries were detected in the HTML content. The security culture appears to be present but could be enhanced with formal policies and transparency.

Recommendations

  1. Implement and publish explicit security headers including CSP, HSTS, and X-Frame-Options to improve browser security.
  2. Create and publish a formal security policy and incident response page with clear contact channels for security issues.
  3. Develop and maintain a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Add visible and verified company contact emails and phone numbers for customer and security communications.
  5. Regularly audit third-party scripts and tracking tools to minimize privacy risks and ensure compliance.

Technical notes

Notes

The website is built on Drupal CMS, a robust and widely used content management system suitable for enterprise-level corporate sites. The use of SVG graphics and responsive images indicates modern front-end practices. Matomo analytics is used as a privacy-friendly alternative to Google Analytics, integrated with a comprehensive cookie consent mechanism. The site loads multiple JavaScript libraries for analytics and marketing tags, including LinkedIn, Google Tag Manager, Meta Pixel, and Twitter tracking. Performance is moderate, with some optimization possible in script loading and image delivery. Mobile optimization is excellent, with adaptive images and responsive design. Accessibility features such as skip links and ARIA roles are present, enhancing usability for assistive technologies. SEO is supported by proper meta tags and Open Graph data. Hosting provider details are not explicitly found in the HTML content.
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.
