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

6 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

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Google Ads

      What to do: Document all third-party data sharing in your privacy policy

  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 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

Concular operates in the real estate and sustainability sectors, focusing on circular economy principles in construction. Their business model revolves around consulting, education, and digital solutions that facilitate circular building practices. The company collaborates with notable partners such as Strabag, Deutsche Bahn, and Siemens, enhancing its credibility and market reach. The presence of multiple related domains and digital tools suggests an ecosystem approach to circular construction. The website content and structure indicate a medium-sized enterprise with a clear focus on innovation and sustainability. Growth indicators include active content updates, educational offerings, and integration of digital lifecycle assessment tools. The partnership ecosystem and professional branding position Concular as a key player in the German circular construction market.

Security posture

The website demonstrates a solid security posture with HTTPS enforced and Cloudflare Bot Management protecting against automated threats. Google reCAPTCHA is implemented to mitigate spam on forms. The cookie consent mechanism is detailed and GDPR-compliant, enhancing privacy protection. However, the absence of a publicly available security policy, incident response plan, or vulnerability disclosure reduces transparency and may impact trust for security-conscious users. No vulnerabilities or exposed sensitive data were detected in the HTML content. Security headers appear to be standard but not explicitly enumerated. Overall, the security maturity is good but could be improved by publishing formal security documentation and enhancing accessibility compliance.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service pages accessible from the website footer or main navigation.
  2. Add a dedicated security policy and incident response information to improve transparency and trust.
  3. Implement and publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Enhance website accessibility features to meet WCAG standards for broader compliance.
  5. Regularly audit and update third-party scripts and plugins to mitigate potential security risks.

Technical notes

Notes

The website is built on WordPress 6.8.2 with a modern tech stack including jQuery, HubSpot integrations, and CookieYes for consent management. Hosting and DNS are managed via Cloudflare, providing performance and security benefits. SEO is enhanced using Rank Math plugin and structured data (JSON-LD) is extensively used for organization, webpage, and article metadata. Performance is moderate with lazy loading and DNS prefetch optimizations. Mobile optimization is good with responsive design and accessible navigation. Technical risks are minimal but depend on maintaining plugin and script updates. The site could benefit from improved accessibility and explicit security headers 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.
