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

Bilfinger SE is an established international industrial services provider specializing in maintenance, expansion, and operation of industrial plants primarily in the energy, chemicals, pharma, and oil & gas sectors. The company operates across Europe, North America, and the Middle East, offering a comprehensive service portfolio including consulting, engineering, manufacturing, assembly, maintenance, and digital applications. The website reflects a mature digital presence built on TYPO3 CMS with a professional design and multilingual support targeting industrial clients globally. Technically, the site uses Apache and PHP 7.4 with various JavaScript libraries and integrates Matomo for analytics and Consentmanager.net for cookie consent management. Security posture is moderate; while security headers and a content security policy are present, the SSL/TLS configuration is currently invalid or missing, which is a critical issue. No WAF or blocking mechanisms are detected, and the site is fully accessible. The domain registration data is consistent with the business claims, showing a long-established domain without privacy protection, supporting legitimacy. Overall, the site is professional and trustworthy but requires urgent SSL/TLS remediation to improve security 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

4 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 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. 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

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

Bilfinger SE holds a strong market position as a full-service industrial services provider with a focus on process industries. Their business model integrates consulting, engineering, and operational services, targeting large industrial clients in energy and manufacturing sectors. The company demonstrates growth and sustainability focus, evidenced by certifications like EcoVadis Gold Medal and inclusion in the STOXX Europe 600 Index. The website supports investor relations, career opportunities, and sustainability initiatives, indicating a mature corporate structure. Partnerships with Salesforce, equity data providers, and compliance platforms enhance their ecosystem. The multilingual and regional site structure supports global reach and localization.

Security posture

The website implements several security best practices including HSTS, X-Frame-Options, X-Content-Type-Options, and a comprehensive Content-Security-Policy. However, the absence of a valid SSL certificate and disabled TLS protocols represent critical vulnerabilities that undermine secure communications and user trust. No known vulnerabilities such as Heartbleed or POODLE are detected. Forms include CAPTCHA and privacy consent, supporting secure data collection. Incident response and security policy information are not publicly found, which could be improved for transparency. Overall, the security posture is moderate but requires immediate SSL/TLS fixes to avoid potential risks.

Recommendations

  1. Install and maintain a valid SSL/TLS certificate to enable HTTPS and secure user connections.
  2. Enable modern TLS protocols (TLS 1.2 and TLS 1.3) and configure strong cipher suites to enhance encryption.
  3. Implement OCSP stapling and session resumption to improve security and performance.
  4. Review and tighten Content-Security-Policy to minimize use of unsafe-inline and unsafe-eval directives.
  5. Publish clear security policies and incident response contacts to improve transparency and trust.
Technical notes

Notes

The website is built on TYPO3 CMS with Apache and PHP 7.4 backend. It uses a variety of JavaScript libraries including jQuery, jQuery UI, Slick, Fancybox, and Mmenu for UI components and interactivity. Matomo analytics is used for user tracking with consent management via Consentmanager.net. DNS is hosted on Microsoft Azure DNS servers, indicating enterprise-grade hosting. The site is mobile optimized with responsive design and good SEO practices including meta tags and Open Graph data. Performance metrics are not provided but the site uses modern frontend assets and lazy loading for images. Technical debt is moderate due to outdated PHP version and missing SSL certificate. Opportunities exist to modernize TLS configuration and improve accessibility features.
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.
