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

COWI is an international consultancy specializing in engineering, architecture, energy, and environmental services. The company positions itself as a leader in co-creating sustainable and aesthetically pleasing solutions that enhance quality of life. The website reflects a mature digital presence with professional design, clear messaging, and a focus on sustainability. The technical infrastructure includes modern web technologies and third-party integrations such as Google Tag Manager and Cookiebot for consent management. The site is mobile-optimized and accessible, with good SEO practices evident in metadata and structured content. Security posture is moderate; HTTPS is used, and cookie consent is implemented, but explicit security headers and policies are not evident. The absence of WHOIS data is a notable gap, reducing domain trustworthiness despite the professional website. Overall, the site demonstrates a solid business and technical foundation but would benefit from enhanced transparency and security disclosures.

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

3 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 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. 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.

    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

COWI operates in the consultancy sector with a focus on engineering, architecture, energy, and environmental solutions. Its market positioning emphasizes sustainability and quality of life improvements, targeting customers requiring expert consultancy services in these sectors. The business model is service-oriented, leveraging expertise to deliver tailored solutions. The website content and branding are consistent and professional, supporting a large enterprise profile. The company uses multiple advertising and tracking services, indicating active marketing and analytics strategies. However, the lack of publicly available WHOIS data and contact information may hinder trust for some stakeholders. No evidence of parent or subsidiary companies was found in the provided data.

Security posture

The website employs HTTPS and a comprehensive cookie consent mechanism, demonstrating awareness of privacy and security compliance. However, no explicit security headers (e.g., CSP, X-Frame-Options) were detected in the provided data, and no security or incident response policies are published. The extensive use of third-party tracking and advertising services increases the attack surface and privacy risks, though these are managed via consent. The absence of WHOIS data and lack of direct contact channels for security incidents are weaknesses. Overall, the security posture is moderate but could be improved by publishing security policies, implementing additional HTTP security headers, and providing incident response contacts.

Recommendations

  1. Implement and verify HTTP security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a clear security policy and incident response contact information to improve transparency and readiness.
  3. Add a terms of service page to provide legal clarity and completeness.
  4. Review and minimize third-party tracking where possible to reduce privacy risks and improve user trust.
  5. Investigate and resolve the missing WHOIS data issue to enhance domain trustworthiness and compliance.

Technical notes

Notes

The website uses modern web technologies including JavaScript modules, CSS, and asynchronous script loading for performance optimization. Google Tag Manager and Cookiebot are integrated for analytics and consent management. The site is mobile responsive and accessible, with good SEO metadata and Open Graph tags for social sharing. No CMS or hosting provider details were identified from the provided data. Performance appears moderate based on script usage and content complexity. There is an opportunity to improve technical security by adding missing HTTP headers and publishing security-related documentation.
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.
