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. 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 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

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.

Add-on

Leaked records that mention bwk.de, from OffSeq Breach.

No leaked records found

Breach holds no records for bwk.de right now. New leaks arrive continuously, so monitoring on Breach alerts you if that changes.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

BWK operates in the finance sector, focusing on private equity investments in the German Mittelstand. Its business model revolves around providing capital through majority, minority, and silent partnerships, supporting growth, succession, and management buy-ins/outs. The company has a medium-sized footprint with a long operational history since 1990. Testimonials and partner logos on the site reinforce its market credibility and stable relationships. The absence of social media links suggests a focus on direct business relationships rather than broad digital marketing. Google Analytics usage indicates moderate user tracking for business insights. The company’s strategic positioning as a market leader in its niche is supported by clear communication of its services and investment philosophy.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and cookie consent implemented according to GDPR principles. Email obfuscation reduces spam risks. However, the absence of security headers such as Content-Security-Policy and lack of published security policies or incident response contacts indicate areas for enhancement. No vulnerabilities or exposed sensitive data were detected in the HTML content. The use of Google Analytics is configured with IP anonymization, supporting privacy compliance. Overall, the security posture is good but could benefit from formalized policies and improved header configurations to mitigate advanced threats.

Recommendations

  1. Implement standard security headers including Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to enhance browser security.
  2. Publish a clear security policy and incident response contact information to improve transparency and readiness.
  3. Add a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  4. Enhance accessibility features to improve compliance and user experience for all users.
  5. Expand SEO optimization with richer meta tags and structured data to improve search engine visibility.

Technical notes

Notes

The website is built on TYPO3 CMS, leveraging Bootstrap 4 and jQuery for responsive and interactive frontend design. The use of Flexslider provides dynamic content presentation. The site loads moderate resources and is mobile optimized with a clear navigation structure. No major technical debt or deprecated libraries were detected. Cookie consent is managed via a dedicated extension, supporting GDPR compliance. Performance is moderate, with potential for optimization in resource loading and caching. The hosting provider is not explicitly identified from the data. Overall, the technical infrastructure is solid and supports the business needs effectively.
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.
