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

4 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. 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

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

Smulders holds a strong market position in manufacturing and EPC services for heavy steel structures, particularly in offshore wind energy. Its competitive advantage lies in its multidisciplinary approach and integration capabilities. The business model focuses on large-scale industrial projects with a B2B target audience including energy companies and infrastructure developers. The company shows growth potential through ongoing projects and a broad geographic footprint. Partnerships with Eiffage and subsidiaries like Iemants enhance operational capacity. The recruitment subdomain indicates active talent acquisition supporting expansion. The company maintains a professional digital presence with social media engagement and transparent policies, reinforcing credibility.

Security posture

The website demonstrates a mature security posture with HTTPS, domain transfer protection, and cookie consent management. However, it lacks a publicly available security policy and incident response contacts, which are important for transparency and trust. No vulnerabilities or exposed sensitive data were detected in the HTML content. The absence of DNSSEC is a minor security gap. Use of third-party analytics is balanced with privacy settings denying ad personalization and analytics storage by default. Overall, the security maturity is good but could be improved by publishing formal security documentation and enhancing HTTP security headers.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Provide clear incident response contact information such as security@ or abuse@ email addresses.
  3. Implement additional HTTP security headers like Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options.
  4. Enable DNSSEC to improve domain name system security.
  5. Regularly review and audit third-party scripts and analytics tools for security and privacy compliance.

Technical notes

Notes

The website is built with modern JavaScript and uses Google Tag Manager and Matomo for analytics, indicating a balanced approach to data collection and privacy. Fonts are loaded via Adobe Typekit, and video content uses the Plyr player. Hosting is provided by Hosting Concepts B.V. with a stable domain registration dating back to 2002. The site is mobile optimized and SEO friendly with proper meta tags and Open Graph data. Performance is moderate, with potential for improvement in loading speed. No CMS was explicitly detected, suggesting a custom or proprietary platform. Accessibility is basic but could be enhanced. Overall, the technical infrastructure supports a professional corporate web presence with room for modernization and security hardening.
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.
