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

REHAU New Ventures is the corporate venturing unit of the REHAU Group, focused on driving innovation by collaborating with startups, investing in promising ventures, and co-creating new businesses beyond the core manufacturing operations. The website presents a professional and well-structured digital presence with clear messaging about their mission, heritage, and leadership team. The company targets startups, investors, and corporate partners, positioning itself as a strategic innovation hub within a medium-sized manufacturing group headquartered in Germany. Technically, the website leverages modern web technologies including Webflow CMS, jQuery, Swiper.js, and integrates Google Tag Manager and a consent management platform, ensuring good performance, mobile optimization, and privacy compliance. Security posture is solid with HTTPS enforced and cookie consent implemented, though there is room for improvement in security headers and incident response transparency. The absence of WHOIS data for the domain raises concerns about domain registration legitimacy, which should be investigated further to ensure trustworthiness. Overall, the site scores well on content quality, technical implementation, and privacy compliance, but business credibility is slightly impacted by the domain registration anomaly.

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.

    • 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. 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

      SSL Certificate Expires Soon

      SSL certificate expires in 18 days

      What to do: Renew SSL certificate before expiration

      • NIS2 21(2)(h)
      • IR 2024/2690 9.2(c): Implementing Regulation (EU) 2024/2690, Annex point 9.2(c): Cryptography

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

The company operates as an essential entity within the manufacturing and technology sectors, leveraging corporate venturing to foster innovation and growth. Its business model combines venture clienting, venture capital investments, and venture building to capture new market opportunities and disrupt traditional industries. The presence of leadership testimonials and active social media profiles on LinkedIn and YouTube enhance credibility and market positioning. The company benefits from its heritage dating back to 1948 under the REHAU Group umbrella, though the New Ventures unit's founding date is not explicitly stated. The website's integration with HubSpot for marketing and consent management tools indicates a mature digital marketing strategy. The lack of phone contact details may limit direct customer engagement but is compensated by email and social media channels. Strategic partnerships and related domains like newventures.io suggest an ecosystem approach to innovation.

Security posture

The website demonstrates a good security baseline with HTTPS enabled and a consent management platform for GDPR compliance. However, no explicit security headers such as Content Security Policy (CSP), X-Frame-Options, or HSTS were detected, which could enhance protection against common web attacks. There is no visible security.txt or vulnerability disclosure page, and no dedicated incident response contact information was found, which are best practices for corporate sites. The absence of WHOIS data for the domain is a notable risk factor, potentially indicating privacy protection or registration issues that could affect trust. No vulnerabilities or exposed sensitive data were identified in the HTML content. Overall, the security posture is good but could be improved with additional transparency and technical controls.

Recommendations

  1. Implement and verify HTTP security headers including CSP, HSTS, and X-Frame-Options to strengthen web security.
  2. Publish a security.txt file and/or vulnerability disclosure policy to facilitate responsible reporting of security issues.
  3. Add explicit incident response contact information (e.g., security@ or abuse@ email addresses) on the website.
  4. Investigate and resolve the missing WHOIS data to ensure domain registration legitimacy and enhance trust.
  5. Continue maintaining GDPR compliance and improve transparency around data retention policies.

Technical notes

Notes

The website is built on the Webflow platform, utilizing jQuery 3.5.1 and Swiper.js for interactive elements. Google Tag Manager is used for analytics and marketing tag management, alongside HubSpot forms for lead capture and a consent management platform for cookie compliance. The site is hosted on Webflow's CDN, providing fast loading times and excellent mobile optimization. Accessibility features are present but could be further enhanced. SEO is well addressed with proper meta tags and Open Graph data. The technical stack is modern and well-maintained, with no visible technical debt or deprecated libraries. Opportunities exist to improve security headers and incident response mechanisms to reduce risk.
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.
