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

Bouwen met Staal operates the Conserveringsinformatiesysteem, a specialized digital information portal focused on the design and assessment of steel constructions for durability, particularly addressing corrosion protection in infrastructure projects such as bascule bridges. The website serves a niche audience of engineers and construction professionals by providing curated, phase-based technical content supported by industry partners. The business model centers on knowledge sharing and industry collaboration rather than direct commercial sales. Technically, the website employs legacy technologies including Prototype.js and Adobe GoLive for content management, with JavaScript-based UI elements such as slideshows and lightbox galleries. While HTTPS is used, there is a lack of modern security headers and cookie consent mechanisms, indicating room for improvement in security and privacy compliance. The site performance is moderate with basic mobile optimization and accessibility features. From a security perspective, the site shows basic best practices such as HTTPS and form POST methods but lacks advanced protections like CSP or HSTS headers. No privacy or cookie policies are published, which is a compliance gap under GDPR. Contact information is clearly provided, enhancing business credibility. No WAF or blocking mechanisms were detected, allowing full content access. Overall, the website is a moderately professional and trustworthy resource within its niche but would benefit from enhanced security measures, privacy compliance, and modernization of its technical stack to improve user trust and regulatory adherence.

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

11 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

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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. 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';…

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

The website positions itself as a niche information system for steel construction durability, targeting professionals in infrastructure and manufacturing sectors. Its competitive advantage lies in curated, phase-based technical content supported by reputable industry partners. The business model is informational and collaborative, relying on partnerships rather than direct sales. The presence of multiple industry logos and professional production credits indicates a strong partnership ecosystem. Growth potential exists through expanding content coverage and improving digital maturity. The company maintains clear contact channels and a professional web presence, though modernization and compliance improvements are needed.

Security posture

The current security posture is basic with HTTPS enabled but lacking critical security headers such as Content Security Policy, HSTS, and X-Frame-Options. No incident response or vulnerability disclosure policies are published, and no security certifications are indicated. The absence of privacy and cookie policies represents a compliance risk under GDPR. Tracking is minimal via MonkeyStats, reducing privacy concerns but also indicating limited analytics sophistication. Overall, the site is functional but would benefit from implementing modern security best practices, formalizing incident response, and enhancing privacy compliance to reduce risk and improve trust.

Recommendations

  1. Implement comprehensive privacy and cookie policies with a consent mechanism to ensure GDPR compliance.
  2. Add security headers including Content Security Policy, HSTS, X-Frame-Options, and X-XSS-Protection to enhance security posture.
  3. Modernize the technology stack to replace legacy libraries and improve mobile responsiveness and accessibility.
  4. Publish an incident response policy and provide dedicated security contact channels to improve security readiness.
  5. Enhance analytics and monitoring capabilities while maintaining user privacy to better understand user behavior and site performance.

Technical notes

Notes

The website uses legacy JavaScript libraries such as Prototype.js and Adobe GoLive for content management, indicating an older technology stack. The site includes JavaScript-based UI components like slideshows and lightbox galleries. The base URL uses HTTPS, but no advanced security headers are detected in the HTML content. The site lacks a modern CMS and appears to be custom or static. Performance is moderate with basic SEO meta tags but limited mobile optimization and accessibility features. There is opportunity to modernize the stack, improve responsiveness, and implement security best practices to reduce technical debt and improve user experience.
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.
