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

3 findings rated critical or high. Fix these first.

  1. 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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  2. GDPR outside view

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

    • 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

  3. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • High

      Domain Expires Soon

      Domain expires in 14 days

      What to do: Renew domain registration before expiration

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

Haufe Group leverages its long-standing expertise in legal and business content to develop AI-powered tools like CoPilot Tax and CoPilot HR, targeting professional users who require reliable, personalized information. The business model centers on B2B SaaS and content services enhanced by AI, maintaining a competitive edge through continuous innovation and quality assurance. The company fosters interdisciplinary collaboration between legal experts and machine learning engineers, ensuring high-quality AI outputs. The partnership ecosystem includes its parent domain haufe.de, reinforcing brand consistency and market position in Germany's technology sector.

Security posture

The website exhibits a good security maturity level with enforced HTTPS, use of CAPTCHA to prevent automated abuse, and careful control of data access via robots.txt. However, the absence of explicit security headers such as Content Security Policy and HSTS is a minor gap. No vulnerabilities or exposed sensitive data were detected in the HTML content. The site lacks a published security policy or incident response contact, which could enhance transparency and readiness. Data protection practices align with GDPR, using dedicated LLM instances and clear editorial oversight of AI-generated content. Overall, the security posture is strong but could benefit from formalized disclosure and header enhancements.

Recommendations

  1. Implement and enforce security headers like CSP, HSTS, and X-Frame-Options to strengthen defense-in-depth.
  2. Publish a dedicated security policy and incident response contact information to improve transparency and trust.
  3. Consider adding a security.txt file to facilitate vulnerability reporting and responsible disclosure.
  4. Enhance data retention and privacy disclosures to align with best practices and user expectations.
  5. Maintain continuous monitoring and evaluation of AI outputs to uphold quality and compliance standards.

It integrates third-party services such as FriendlyCaptcha for bot protection and Google Tag Manager for analytics. The site is well-optimized for performance and mobile responsiveness, with clean semantic HTML and proper meta tags for SEO.

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.
