Risk levelLow

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

Arcadis N.V. is a leading global design and consultancy firm specializing in natural and built assets, operating in over 30 countries with a workforce exceeding 34,000 professionals. The company focuses on infrastructure, sustainability, energy, transportation, and real estate sectors, delivering services that modernize critical infrastructure and provide asset advisory. The website reflects a mature digital presence with professional design, comprehensive content, and clear navigation tailored to business and government clients. Technically, the site leverages modern frameworks such as React, integrates Azure Application Insights for telemetry, and employs Google Tag Manager and Cookiebot for analytics and consent management, indicating a high level of digital maturity. Security posture is strong with HTTPS enforcement, security headers, and no visible vulnerabilities, though the absence of a public vulnerability disclosure policy and incident response contacts suggests room for improvement. Overall, the site is trustworthy and professional, though the lack of WHOIS data transparency slightly reduces domain trustworthiness. Strategic recommendations include enhancing transparency on security incident response and maintaining up-to-date third-party components.

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

2 findings rated critical or high. Fix these first.

  1. 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 Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

  2. 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 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

Arcadis holds a strong market position as a global consultancy in infrastructure and environmental sectors, with a business model centered on professional services and sustainability advisory. Revenue streams likely derive from large-scale infrastructure projects, asset management, and consulting services. The target audience includes governments, large enterprises, and infrastructure operators. The company demonstrates growth through partnerships and a broad geographic footprint. The website's content and structure support a high level of professionalism and trust, with clear investor information and governance disclosures. The use of advanced analytics and consent management tools reflects a commitment to data privacy and regulatory compliance.

Security posture

The website exhibits a mature security posture with enforced HTTPS, comprehensive security headers, and no exposed sensitive data. Use of Azure Application Insights and Google Tag Manager is well integrated with consent management via Cookiebot, supporting GDPR compliance. However, the absence of a public vulnerability disclosure program and incident response contact details limits transparency in security incident handling. No critical vulnerabilities or security misconfigurations were detected in the content. The domain WHOIS data is unavailable, which is a minor concern for domain trust but does not impact the website's operational security. Overall, the security maturity is high but could benefit from enhanced transparency and formalized disclosure policies.

Recommendations

  1. Implement and publish a formal vulnerability disclosure policy to encourage responsible reporting.
  2. Provide clear incident response contact information, such as a security@ or abuse@ email address.
  3. Regularly audit and update third-party libraries and scripts to mitigate potential vulnerabilities.
  4. Enhance transparency around data protection officer contact details to improve GDPR compliance.
  5. Maintain continuous monitoring of security headers and SSL/TLS configurations to ensure best practices.

Technical notes

Notes

The website is built on a modern technology stack including React for frontend rendering, Azure Application Insights for telemetry, and Google Tag Manager for analytics. Hosting appears to be on Microsoft Azure, providing robust infrastructure support. The site is mobile-optimized with responsive design and accessibility features. SEO is well implemented with proper meta tags and Open Graph data. The use of Episerver CMS is implied, supporting content management needs. Performance is fast with deferred script loading and optimized media assets. Technical risks are minimal, though ongoing maintenance of third-party scripts and libraries is essential to avoid vulnerabilities. Overall, the technical infrastructure supports a scalable, secure, and user-friendly digital presence.
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.
