Security score

77/100

Risk levelLow

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

NCC is a large Nordic construction and infrastructure company focused on delivering residential buildings, commercial premises, and infrastructure projects. The website presents a professional image with clear branding and a focus on collaboration and innovation in the construction sector. The company targets customers and partners in Denmark and the broader Nordic region. Technically, the website uses modern web technologies including JavaScript, Microsoft Application Insights for telemetry, and Cookiebot for cookie consent management. The site is mobile-optimized and includes SEO best practices, though some security headers are missing. Security posture is strong with HTTPS enforced and telemetry in place, but transparency could be improved by publishing explicit privacy policies, terms of service, and security policies. Overall, the site is trustworthy and well-maintained with extensive analytics and marketing tools used in compliance with GDPR via consent mechanisms.

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 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

NCC operates in the real estate and construction sectors, providing essential infrastructure and building services. The company leverages digital tools for analytics and marketing, indicating a mature digital presence. The use of multiple third-party services such as Google Analytics, Hotjar, and Meta Platforms for advertising suggests a focus on data-driven marketing and customer insights. The absence of explicit contact information on the main page may indicate reliance on partner or subsidiary sites for direct customer engagement. The company appears to maintain a consistent brand and has a strong market position in Denmark. No suspicious domains or partners were identified, reinforcing the legitimacy of the business.

Security posture

The website enforces HTTPS and uses Microsoft Application Insights for telemetry, which is a positive security indicator. Cookie consent is managed via Cookiebot, ensuring compliance with GDPR cookie regulations. However, the absence of explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options is a gap that could expose the site to certain web-based attacks. No vulnerabilities or exposed sensitive data were detected in the provided content. There is no visible security policy or incident response contact information, which could be improved to enhance trust and readiness. Overall, the security posture is good but could be strengthened by adding missing headers and transparency documents.

Recommendations

  1. Implement and publish a comprehensive privacy policy and terms of service pages accessible from the main navigation or footer.
  2. Add essential security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  3. Provide clear contact information including company emails and phone numbers for customer support and security incident reporting.
  4. Establish and publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  5. Enhance transparency by publishing a security policy and data protection officer contact details to comply with GDPR and build user trust.

Technical notes

Notes

The website uses a modern tech stack with JavaScript, Microsoft Application Insights, and Cookiebot for consent management. Google Fonts are used for typography. The site is mobile-optimized and includes SEO-friendly meta tags and Open Graph data for social media sharing. Performance is moderate with asynchronous loading of scripts. No CMS was explicitly detected from the provided content. Hosting provider details are not evident. The site uses HTTPS exclusively, indicating good baseline security. There is room for improvement in security headers and explicit documentation of policies. The technical implementation supports a professional and user-friendly experience but could benefit from enhanced security and compliance 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.
