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. 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"

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

  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
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

Bilthouse operates in the finance and real estate sectors, focusing on mortgage and private loan brokerage with a digital and personal hybrid business model. The company targets individuals and businesses in Germany seeking property financing solutions. Its market position is strong as a leading provider with a large employee base and significant transaction volume. The group structure includes multiple subsidiary brands and a fintech CRM platform, indicating a diversified service offering and integrated technology approach. The management team is experienced with strong industry backgrounds, enhancing credibility. The website's external links and partner domains confirm the ecosystem of related brands and services. No direct contact details are publicly displayed, which may be a strategic choice for lead generation via forms or other channels.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and domain transfer lock enabled. The use of Usercentrics for cookie consent and Google Tag Manager with default denied consent settings shows attention to privacy and compliance. However, the absence of DNSSEC and explicit security headers suggests room for improvement. No vulnerability disclosure or incident response information is provided, which could be enhanced to improve transparency and trust. No exposed sensitive data or vulnerable libraries were detected in the provided content. Overall, the security posture is good but could be strengthened with additional technical controls and published policies.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement standard security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Publish a clear security policy and incident response contact information on the website.
  4. Add a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Consider adding visible company contact information to improve user trust and support.

Technical notes

Notes

The website is built on HubSpot CMS, leveraging Bootstrap 5.2 and jQuery 3.6.1 for frontend UI components, and Swiper for interactive elements. It uses Usercentrics for GDPR-compliant cookie consent management and Google Tag Manager for analytics and marketing tags. The site is mobile optimized with responsive design and includes proper meta tags for SEO and social sharing (Open Graph and Twitter cards). Performance is moderate, likely influenced by external scripts and HubSpot platform overhead. Accessibility is basic but could be improved with more ARIA attributes and semantic HTML. The domain is registered with a reputable German registrar and has a long history consistent with the business age.
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.
