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

5 findings rated critical or high. Fix these first.

  1. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection
    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection
  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 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';…
  3. 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 · found on this site
  • 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

ibau GmbH holds a strong position in the German construction information market, offering key services like tender notifications and decision maker targeting. Their business model relies on subscription services for construction professionals and companies. The company leverages partnerships, such as with share-it.datenportal-muensterland.de, to enhance data offerings. The website reflects a medium-sized enterprise with consistent branding and trust signals including privacy compliance and cookie consent. Revenue streams likely include subscription fees and advertising partnerships. The target customer segment is construction industry professionals and businesses seeking procurement opportunities. The company demonstrates digital maturity through integration of marketing and analytics tools, though there is room for improvement in publishing security and incident response policies.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and a comprehensive cookie consent mechanism that aligns with GDPR requirements. No exposed sensitive data or vulnerable libraries were detected in the provided content. However, the absence of a published security policy, incident response plan, or vulnerability disclosure program indicates gaps in transparency and readiness. The use of third-party services like HubSpot and Typeform introduces dependencies that require ongoing security management. Security headers were not explicitly detected in the provided data, suggesting an opportunity to enhance HTTP security headers. Overall, the site is secure for users but could improve in formalizing and publishing security governance and incident response information.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and frameworks.
  2. Implement and publicize an incident response plan and contact channels for security issues.
  3. Add and enforce HTTP security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Establish a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  5. Enhance transparency by providing direct company contact emails and phone numbers for support and security.

Technical notes

Notes

The website uses a modern JavaScript-based front end with asynchronous loading of scripts including Google Tag Manager and Cookiebot for consent management. Fonts are preloaded for performance optimization. The site includes accessibility features such as WCAG toggle styles and cookie consent dialogs with ARIA roles. The CMS is not explicitly identified, but the presence of HubSpot forms and Typeform integrations indicates a hybrid marketing and data collection infrastructure. Performance is moderate with some deferred script loading. Mobile optimization and SEO meta tags are well implemented. Hosting provider and server details are not disclosed. Technical risks include reliance on multiple third-party services and lack of visible security headers. Opportunities exist to improve technical documentation 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.
