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

4 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 Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  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 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

BHW Bausparkasse AG holds a strong market position in the German finance sector, focusing on building savings and home financing. Its business model revolves around providing tailored financial products such as Bauspar contracts, modernization loans, and climate-friendly financing options. The company leverages partnerships with Deutsche Bank and Postbank to extend its service reach and customer base. Revenue streams likely include interest income from loans and fees associated with savings contracts. The target customers are private individuals planning to build, buy, modernize, or save for real estate. The website content and navigation reflect a customer-centric approach with extensive product information and digital services like myBHW online banking. The partnership ecosystem and comprehensive service offerings indicate a strategic focus on integrated financial solutions and digital transformation.

Security posture

The current security posture of BHW Bausparkasse AG's website is solid but has room for enhancement. The use of TLS 1.2 with a strong cipher suite ensures encrypted communications, and SPF and DMARC records help protect against email spoofing. However, the absence of HSTS, OCSP stapling, and TLS 1.3 support limits the site's resilience against certain attacks and performance optimizations. The lack of session resumption mechanisms may impact user experience and security. No explicit security policy or incident response information is publicly available, which could be a gap in transparency and readiness. The cookie consent mechanism and GDPR-compliant privacy policy demonstrate good data protection practices. Overall, the security score is moderate, with recommendations to adopt modern TLS features and improve security header configurations to strengthen the security posture.

Recommendations

  1. Enable HTTP Strict Transport Security (HSTS) with includeSubDomains and preload to enforce HTTPS and prevent downgrade attacks.
  2. Implement OCSP stapling to improve SSL certificate revocation checking and reduce latency.
  3. Upgrade server configuration to support TLS 1.3 for enhanced security and performance benefits.
  4. Enable session resumption via session tickets or cache to improve user experience and reduce handshake overhead.
  5. Publish a security policy and incident response contact information to increase transparency and preparedness.
Technical notes

Notes

The website is built on Adobe Experience Manager, a robust enterprise CMS, indicating a mature technical infrastructure. It uses Webtrekk for analytics and tracking, with a cookie consent mechanism to comply with privacy regulations. The site employs SVG icons and modular JavaScript components for UI interactivity. Performance is moderate with a page load time of approximately 3.7 seconds and a page size of about 52 KB, which is acceptable but could be optimized further. Mobile optimization is good, with responsive design and accessible navigation. SEO practices are well implemented with meta tags, Open Graph data, and canonical links. Hosting appears to be managed by Deutsche Bank or related infrastructure, ensuring enterprise-grade reliability. Technical risks include outdated TLS protocol support and missing advanced security headers, which should be addressed to reduce potential vulnerabilities.
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.
