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

Endress+Hauser AG is a global leader in industrial measurement instrumentation and automation solutions, serving diverse sectors including energy, chemical, life sciences, water treatment, and oil & gas. The company offers a comprehensive portfolio of products and services, including flow, level, liquid analysis, optical analysis, pressure, and temperature measurement devices, alongside software and system products. Their website reflects a mature digital presence with extensive product information, customer support, and training resources, targeting industrial process engineers and related professionals worldwide. Technically, the website employs modern web technologies such as JavaScript, CSS, JSON-LD structured data, and utilizes Tealium for analytics and tag management. The site is hosted on reliable infrastructure, likely Amazon AWS, and demonstrates good mobile optimization, accessibility, and SEO practices. However, performance metrics indicate slow loading times, which may impact user experience. From a security perspective, the site has critical deficiencies: it lacks a valid SSL certificate and does not enable HTTPS or modern TLS protocols, severely impacting its security posture. While some security headers are present, the absence of proper SSL/TLS configuration is a major risk. Privacy and cookie policies are well implemented with consent mechanisms, and contact information is clearly provided, enhancing trust. Overall, the site is professionally designed and content-rich but requires urgent security improvements to protect user data and maintain trust. Strategic recommendations include immediate SSL certificate installation, enabling HTTPS and modern TLS versions, and enhancing security headers and session management. These steps will significantly improve the site's security score 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

7 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

  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"

    • 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

  • 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

Endress+Hauser AG operates as an essential entity in the industrial automation and measurement sector, with a strong presence in energy, manufacturing, chemical, life sciences, water & wastewater, oil & gas, and mining industries. The company leverages a B2B business model, providing high-quality instrumentation and software solutions to industrial clients globally. Their market position as a global leader is supported by a broad product portfolio, extensive service offerings, and a strong brand presence. The website highlights their commitment to sustainability and innovation, targeting industrial process engineers and decision-makers. Subsidiaries such as Endress+Hauser SICK, Analytik Jena, and Innovative Sensor Technology expand their market reach and technological capabilities. The company maintains a professional digital ecosystem with integrated customer portals and training programs, indicating a mature and customer-focused operation.

Security posture

The current security posture of the website is weak due to the absence of a valid SSL certificate and lack of HTTPS enforcement, exposing users to potential data interception and man-in-the-middle attacks. Although some security headers like X-Content-Type-Options and Strict-Transport-Security are present, their effectiveness is nullified without proper SSL/TLS configuration. No known vulnerabilities such as Heartbleed or POODLE are detected, but the lack of modern TLS protocols and session resumption mechanisms indicates outdated security practices. Privacy policies and cookie consent mechanisms are well implemented, showing compliance with GDPR requirements. The site lacks explicit incident response or vulnerability disclosure information, which could be improved to enhance security transparency and readiness.

Recommendations

  1. Install and maintain a valid SSL/TLS certificate to enable HTTPS across the entire site.
  2. Enable modern TLS protocols (TLS 1.2 and TLS 1.3) and disable deprecated protocols.
  3. Configure HSTS header with includeSubDomains and preload options to enforce HTTPS.
  4. Implement OCSP stapling and session resumption to improve security and performance.
  5. Publish a vulnerability disclosure policy and incident response contact information to enhance security transparency.

Technical notes

Notes

The website uses a modern tech stack including JavaScript, CSS, JSON-LD for structured data, and Tealium for analytics and tag management. It appears to be built with GWT (Google Web Toolkit) and hosted on Amazon AWS infrastructure. The site is mobile-optimized and accessible with good SEO practices. However, performance is slow, possibly due to large resource sizes or server response times. The absence of a valid SSL certificate and disabled TLS protocols represent significant technical risks. The site includes comprehensive navigation, product catalogs, and customer portals, indicating a complex and mature technical environment. Opportunities exist to improve performance, security, and user experience through optimization and modernization efforts.
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.
