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

SGL Carbon is a global technology leader specializing in carbon-based materials and solutions, serving key industries such as sustainable mobility, energy, semiconductor technology, and chemical manufacturing. The company operates worldwide with a strong presence in Europe, North America, and Asia, employing approximately 4,700 people and generating significant revenue. The website reflects a mature and professional business with comprehensive content, clear branding, and a focus on sustainability and innovation. Technically, the site is built on TYPO3 CMS and integrates modern marketing and analytics tools, but suffers from a critical lack of HTTPS and valid SSL certificates, severely impacting security posture. Privacy compliance is well addressed with cookie consent mechanisms and detailed policies. Overall, the site is trustworthy and professional but requires urgent security improvements to protect users and data.

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 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

  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 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

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

SGL Carbon holds a strong market position as a leading manufacturer of specialty graphite, carbon fibers, and composite materials. Their business model focuses on B2B industrial clients in energy, transport, and manufacturing sectors, providing high-tech materials and process technologies. The company emphasizes sustainability and corporate responsibility, supported by transparent investor relations and compliance frameworks. Their digital presence is consistent with their corporate identity and supports their global operations. The absence of direct contact emails and phone numbers on the homepage suggests a controlled communication strategy, likely directing inquiries through dedicated contact forms and service pages.

Security posture

The website demonstrates good security header implementation and content security policies, but the absence of a valid SSL certificate and HTTPS support is a critical vulnerability. This exposes users to potential data interception and undermines trust. No advanced security policies or incident response information is publicly available, and no vulnerability disclosure or security.txt files are found. The site uses modern analytics and consent management tools, indicating awareness of privacy requirements, but the lack of secure transport is a major compliance and security gap. Immediate remediation of SSL/TLS issues is essential to improve the security posture.

Recommendations

  1. Obtain and deploy a valid SSL/TLS certificate to enable HTTPS across the entire site.
  2. Enable and enforce modern TLS protocols (TLS 1.2 and TLS 1.3) and disable insecure protocols.
  3. Implement HTTP Strict Transport Security (HSTS) with includeSubDomains and preload directives.
  4. Publish a security policy and incident response contact information to enhance transparency.
  5. Add a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  6. Improve accessibility features and performance metrics to enhance user experience.
  7. Consider publishing direct contact emails or phone numbers for security and incident reporting.
Technical notes

Notes

The website is powered by TYPO3 CMS, a robust and widely used enterprise content management system. It uses jQuery and integrates Google Tag Manager, Google Analytics, Hotjar, and Usercentrics CMP for marketing, analytics, and consent management. Hosting is via Amazon CloudFront CDN, ensuring global content delivery. The site employs lazy loading for images and responsive design for mobile optimization. However, the lack of HTTPS and SSL/TLS support is a significant technical deficiency. Performance data is unavailable, but the use of modern tools suggests moderate to good performance. SEO is supported by meta tags, Open Graph, and JSON-LD structured data. Overall, the technical infrastructure is solid but requires urgent security upgrades.
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.
