0–100, higher is better. How it is calculated

H&Z Unternehmensberatung AG is a well-established management consulting firm based in Munich, Germany, with a strong focus on strategy, procurement, transformation, sustainability, innovation, and technology. Founded in 1997, the company operates globally with over 600 consultants across 14 offices and is part of the larger H&Z Group and The Transformation Alliance. The website is professionally designed, content-rich, and targets leading organizations seeking strategic consulting services. Technically, the site uses modern frameworks such as Next.js and is hosted on Vercel, with cookie consent managed by Usercentrics and analytics via Google Tag Manager. However, the security posture is weakened by an invalid SSL certificate and lack of modern TLS protocol support, which poses risks to user trust and data security. Privacy compliance is partial, with cookie consent present but no visible privacy or terms of service policies. Overall, the site demonstrates high business credibility but requires urgent security improvements to align with best practices.

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

9 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

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

  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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

  3. 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"

    • 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

H&Z holds a strong market position as a trusted strategic consulting partner with a comprehensive service portfolio addressing key business challenges in strategy, procurement, transformation, and sustainability. Their business model revolves around delivering measurable impact through expert consulting and implementation support. The company leverages a broad partnership ecosystem including The Transformation Alliance and sustainability initiatives like SUSTAINX and Railsponsible. Growth indicators include a large consultant base and multiple offices worldwide. The website content and structured data reinforce the company's legitimacy and professional branding, appealing to enterprise clients in diverse industries. Their digital presence integrates modern technologies but lacks some security and privacy policy transparency, which could be improved to enhance client trust.

Security posture

The website's security posture is currently suboptimal due to an invalid SSL certificate and absence of enabled TLS protocols, which are critical for secure HTTPS communication. While security headers such as HSTS are present, the lack of OCSP stapling and session resumption reduces security and performance. No vulnerabilities like Heartbleed or POODLE were detected, but the missing valid certificate is a critical issue that undermines user trust and data protection. There is no evidence of a formal security policy or incident response contact channels. Privacy compliance is partial, with cookie consent implemented but no explicit privacy policy or terms of service found. Overall, the site requires immediate remediation of SSL issues and enhanced privacy documentation to meet industry standards and regulatory requirements.

Recommendations

  1. Obtain and deploy a valid SSL/TLS certificate to enable secure HTTPS connections.
  2. Enable modern TLS protocols (TLS 1.2 and TLS 1.3) and disable deprecated versions.
  3. Implement OCSP stapling and session resumption to improve certificate validation and performance.
  4. Publish comprehensive privacy policy and terms of service documents accessible from the website.
  5. Establish and disclose a security policy and incident response contact information to enhance transparency and trust.

Technical notes

Notes

The website is built using Next.js framework and hosted on Vercel, indicating a modern and scalable infrastructure. It uses Usercentrics for cookie consent management and Google Tag Manager for analytics and tracking. The site is mobile responsive with good SEO optimization and accessibility basics. However, the SSL configuration is invalid, and no TLS protocols are enabled, which is a significant technical risk. Performance data is unavailable, but the use of Vercel and Next.js suggests potential for fast loading times. The site uses structured data (JSON-LD) for organization and webpage metadata, enhancing search engine understanding. Overall, the technical stack is modern but requires urgent security upgrades to ensure safe user interactions.
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.
