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

2 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.

    • 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. 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
  • 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's business model centers on B2B SaaS, content publishing, and professional training services targeting corporate clients and professionals. Their diversified portfolio includes software tools, databases, magazines, books, and online training across multiple sectors including HR, tax consulting, legal, finance, sustainability, and real estate. The company leverages partnerships and subsidiaries such as Advolux and Rudolf AI to expand offerings. Their digital ecosystem is well-integrated with e-commerce and account management portals. Haufe's market presence is supported by consistent branding, customer testimonials, and active social media engagement, indicating a stable and growth-oriented business with a focus on innovation and customer support.

Security posture

The website enforces HTTPS and integrates a consent management platform (Usercentrics) to comply with GDPR cookie regulations. Security best practices include secure forms and no visible exposure of sensitive data. However, the absence of explicit security headers like Content-Security-Policy and lack of published security policies or incident response contacts suggest room for improvement in transparency and defense-in-depth. No vulnerabilities or suspicious scripts were detected in the provided content. The security score is good but could be enhanced by publishing a vulnerability disclosure policy and implementing additional HTTP security headers.

Recommendations

  1. Implement and publish a formal security policy and incident response contact information on the website.
  2. Add explicit HTTP security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection.
  3. Publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  4. Regularly audit third-party scripts and dependencies for vulnerabilities and update them promptly.
  5. Enhance transparency around data retention policies and provide clearer user information on analytics data usage.

Technical notes

Notes

The website is built on the Webflow CMS platform, utilizing modern JavaScript libraries including jQuery 3.5.1 and Slick Slider for UI components. Usercentrics is used for GDPR-compliant consent management, and Google Tag Manager facilitates analytics and marketing tags. The site is hosted on Webflow's infrastructure with CDN support for static assets, ensuring fast load times and good performance. Mobile responsiveness and accessibility are well addressed. The technical implementation is modern and robust, with opportunities to improve security headers and formalize security documentation.
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.
