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

DMT GROUP is a well-established global engineering services and consulting company with a history dating back to 1737. It operates primarily in the energy, infrastructure, mining, and engineering sectors, offering a broad range of services including engineering, consulting, geotechnics, exploration, and critical infrastructure protection. The company is part of the TÜV NORD GROUP, which enhances its market credibility and access to resources. The website reflects a professional and comprehensive digital presence with clear business information, structured data, and rich content targeting industrial clients worldwide. Technically, the website is built on TYPO3 CMS and uses common web technologies such as Apache server, Google Analytics, and LinkedIn Insight Tag for analytics and marketing. However, the site lacks a valid SSL certificate and does not support HTTPS, which is a critical security shortfall. The absence of modern TLS protocols and security headers further weakens its security posture. Performance is rated slow due to missing SSL and possibly other optimizations. Privacy compliance is partial, with a privacy policy present but no visible cookie consent mechanism. Security-wise, the site has configured SPF and DMARC records for email security and shows no signs of common vulnerabilities like Heartbleed or POODLE. However, the lack of HTTPS and security headers significantly reduces the overall security score. There is no explicit incident response or vulnerability disclosure information available on the site. Overall, the website is professional and content-rich but requires urgent improvements in security infrastructure, especially SSL/TLS implementation, to protect user data and enhance trust. Privacy compliance could also be improved by adding cookie consent mechanisms. Strategic recommendations include implementing HTTPS, enhancing security headers, and improving privacy transparency.

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. 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
    • 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';…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

    • 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

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

DMT GROUP holds a strong market position as a global engineering and consulting firm with a legacy of over 280 years. Its affiliation with TÜV NORD GROUP provides additional credibility and access to a broad network. The company targets industrial sectors such as energy, mining, and infrastructure, offering specialized services that include engineering, consulting, geotechnics, and exploration. The business model focuses on delivering sustainable value through innovation and digitalization. The website content and structured data indicate a focus on global clients and multiple service lines, supported by a network of 13 companies across 30 locations. The presence of innovation projects and certifications suggests active engagement in industry advancements. Partnerships and subsidiaries are evident, enhancing service breadth and market reach.

Security posture

The current security posture of the website is weak due to the absence of a valid SSL certificate and lack of HTTPS support, which is a critical vulnerability for any modern website. No TLS protocols are enabled, and security headers are minimal, lacking important protections such as HSTS, Content-Security-Policy, and X-Frame-Options. Although email security is strengthened by SPF and DMARC records, the website itself exposes users to risks of data interception and man-in-the-middle attacks. No incident response or vulnerability disclosure policies are visible, indicating limited preparedness for security incidents. The use of Google Analytics and LinkedIn tracking scripts without a cookie consent mechanism raises privacy compliance concerns. Immediate remediation is required to implement HTTPS, enable modern TLS protocols, and enhance security headers to protect users and maintain trust.

Recommendations

  1. Implement a valid SSL/TLS certificate and enable HTTPS across the entire website immediately.
  2. Enable modern TLS protocols (TLS 1.2 and TLS 1.3) and disable obsolete protocols.
  3. Configure HTTP security headers including HSTS with includeSubDomains and preload, Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Introduce a cookie consent mechanism to comply with GDPR and enhance privacy transparency.
  5. Publish a clear security policy and vulnerability disclosure program to improve incident response readiness and user trust.

Technical notes

Notes

The website is hosted on an Apache server and built using TYPO3 CMS, a mature and widely used content management system. It uses common JavaScript libraries such as jQuery and Slick Carousel for UI components. Analytics and marketing tools include Google Analytics and LinkedIn Insight Tag. The site is multilingual with English and German options. Performance is currently slow, likely due to lack of HTTPS and possible unoptimized assets. The site is mobile optimized with good accessibility and SEO practices, including structured data in JSON-LD format for organization and breadcrumb schema. DNS records are properly configured with SPF, DMARC, and MX records pointing to trusted mail servers. However, the lack of SSL/TLS and modern security configurations represents a significant technical risk that could impact business operations and user trust.
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.
