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

Sulzer Ltd is a globally recognized leader in fluid engineering, specializing in the manufacturing and servicing of pumps, agitators, mixers, separation, and purification technologies. The company serves essential industries such as energy, manufacturing, and process industries, positioning itself as a key player in enabling sustainable and efficient industrial operations worldwide. Their website reflects a mature enterprise with comprehensive product and service offerings, strong branding, and a clear focus on sustainability and innovation. Technically, the website employs a modern technology stack including Apache server, Vue.js framework, and integrates multiple third-party analytics and marketing tools such as Google Analytics, Pardot, and Hotjar. The site is hosted with Azure DNS and demonstrates good SEO and mobile optimization practices. However, performance metrics are not explicitly available. From a security perspective, while the site implements several important security headers and content security policies, it critically lacks a valid SSL/TLS certificate and does not support HTTPS, which severely undermines its security posture. This exposes users to potential risks and reduces trustworthiness. Privacy compliance is well addressed with clear privacy and cookie policies and consent mechanisms, aligning with GDPR requirements. Overall, the website is professional and credible but requires urgent remediation of its SSL/TLS configuration to ensure secure communications and improve its security score. Strategic recommendations include immediate SSL certificate installation, enabling modern TLS protocols, and enhancing security header configurations to protect users and maintain 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

5 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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

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

Sulzer Ltd operates as an essential industrial company with a focus on energy and manufacturing sectors. Its business model revolves around providing high-quality fluid engineering products and services to industrial clients globally. The company maintains a strong market position as a global leader with a diversified portfolio including pumps, mechanical seals, agitators, compressors, and process plants. Revenue streams likely derive from product sales, maintenance services, spare parts, and digital solutions. The website indicates a mature enterprise with a well-established brand, supported by investor relations and sustainability initiatives. The company leverages partnerships and digital marketing tools to enhance customer engagement and market reach. Growth indicators include ongoing innovation, sustainability commitments, and extensive training programs.

Security posture

The current security maturity level of Sulzer's website is low due to the absence of a valid SSL certificate and lack of HTTPS support, which is a critical vulnerability. While security headers such as XSS protection, content security policy, and HSTS directives are present, the lack of TLS protocols and certificate transparency compliance significantly weakens the security posture. There are no visible signs of exposed sensitive data or vulnerable libraries, and forms appear to be protected with reCAPTCHA. However, the missing HTTPS undermines data protection and user trust. Compliance gaps exist primarily in transport layer security. Incident response and security policy information are not publicly available, indicating potential gaps in transparency and readiness. Overall, the site requires urgent security improvements to meet industry best practices and regulatory requirements.

Recommendations

  1. Install and maintain a valid SSL/TLS certificate to enable HTTPS across the entire site.
  2. Enable TLS 1.2 or higher protocols and disable deprecated SSL/TLS versions.
  3. Activate HSTS with includeSubDomains and preload flags to enforce secure connections.
  4. Implement OCSP stapling to improve certificate revocation checking and reduce latency.
  5. Review and update security headers and Content Security Policy to minimize risks from inline scripts and unsafe eval usage.
  6. Publish a clear security policy and incident response contact information to enhance transparency and trust.
Technical notes

Notes

The website is hosted on an Apache 2.4.9 Unix server with DNS managed by Azure DNS services. It uses modern front-end technologies including Vue.js and integrates multiple third-party services such as Google Tag Manager, Google Analytics, Pardot marketing automation, and OneTrust for cookie consent management. The site is well structured with comprehensive navigation and multilingual support. Performance data is unavailable, but the presence of deferred JavaScript and CSS bundling suggests optimization efforts. Accessibility and SEO are addressed with proper meta tags, canonical links, and language alternates. However, the lack of HTTPS and valid SSL certificate is a significant technical risk. The site uses extensive external resources and tracking scripts, which may impact privacy and performance if not managed carefully.
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.
