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

Plansee SE is a globally recognized manufacturer specializing in refractory metals such as molybdenum, tungsten, and tantalum, serving high-tech industries including electronics, aerospace, and energy. With a century of experience and multiple production sites worldwide, Plansee positions itself as a leader in high-performance materials and sustainable manufacturing solutions. The website reflects a mature digital presence built on Adobe Experience Manager and Next.js, leveraging Akamai CDN and Google Tag Manager for performance and analytics. However, the current lack of a valid SSL certificate and disabled TLS protocols represent critical security vulnerabilities that undermine user trust and data protection. Despite these issues, the site maintains comprehensive privacy and cookie policies aligned with GDPR, and showcases certifications like EcoVadis Gold and ASML Sustainability Excellence Award, reinforcing its market credibility. Strategic improvements in SSL/TLS deployment and enhanced security configurations are recommended to elevate the overall security posture and user confidence.

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

Plansee operates in the manufacturing sector with a focus on refractory metals for industrial applications. Its business model is B2B, targeting sectors such as electronics, mobility, manufacturing technology, medical technology, energy, and aerospace. The company benefits from a strong brand legacy dating back to 1921 and maintains a global footprint with 12 production sites. Revenue streams likely include product sales, custom manufacturing solutions, and sustainability consulting. The company actively engages in sustainability initiatives and digital transformation, evidenced by its customer platform 'My Plansee' and sustainability reports. Partnerships and certifications enhance its competitive advantage. The website content and structure support a professional and trustworthy image, appealing to industrial clients and partners.

Security posture

The website demonstrates partial adherence to security best practices with several security headers implemented, including X-XSS-Protection, X-Content-Type-Options, and Content-Security-Policy. However, the absence of a valid SSL certificate and disabled TLS protocols are critical flaws that expose users to potential data interception and trust issues. HSTS is configured but not enabled, and advanced SSL features like OCSP stapling and session resumption are missing. No incident response or vulnerability disclosure information is found, indicating potential gaps in security transparency. The site does not expose sensitive data or vulnerable libraries, but the SSL/TLS deficiencies significantly reduce the overall security posture. Immediate remediation of SSL/TLS issues is essential to protect user data and maintain compliance.

Recommendations

  1. Obtain and deploy a valid SSL/TLS certificate to enable HTTPS and secure communications.
  2. Enable TLS 1.2 or higher protocols and disable insecure protocols to strengthen encryption.
  3. Activate and configure HSTS with includeSubDomains and preload options to prevent protocol downgrade attacks.
  4. Implement OCSP stapling and session resumption to improve SSL performance and security.
  5. Publish a vulnerability disclosure policy and incident response contact information to enhance security transparency and readiness.
Technical notes

Notes

The website is built using modern web technologies including React with Next.js framework and Adobe Experience Manager CMS. It uses Akamai CDN for content delivery and Google Tag Manager for analytics and marketing. The site is well-structured with multilingual support and optimized for mobile devices. However, performance metrics are not available, and SSL/TLS configuration is currently invalid, which is a significant technical risk. The site uses standard security headers but lacks advanced SSL features. The technical stack is robust but requires urgent security upgrades to align with best practices and ensure safe user interactions.
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.
