REHAU · Manufacturing · N/a

Medium risk. 5 critical or high findings in GDPR outside view and SSL/TLS.

Security score

55/100

Risk levelMedium

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

The website for rehau.com is currently inaccessible due to a security access denial page served by Akamai's WAF, preventing retrieval of any meaningful content or metadata. REHAU is a known global enterprise specializing in polymer-based manufacturing solutions, primarily serving the construction, automotive, and industrial sectors. The domain and DNS records are consistent with a legitimate, established business. However, the SSL certificate is invalid or missing, resulting in no HTTPS availability, which is a critical security issue. Security headers are present but their effectiveness is undermined by the lack of valid SSL. Due to the blocked content, no privacy, cookie, or contact information is available for analysis. Overall, the site’s security posture is weak due to SSL issues, and the user experience is non-existent because of the access denial. Strategic recommendations include obtaining a valid SSL certificate, enabling modern TLS protocols, and ensuring the WAF configuration allows legitimate user access.

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

5 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

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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.

    • 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

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

REHAU operates as an important entity in the manufacturing sector, focusing on polymer solutions for various industries. The business model is B2B with a global footprint. The domain age and WHOIS data support the legitimacy and maturity of the company. No direct business content or marketing information is accessible on the website due to the WAF block, limiting insights into revenue streams or partnerships. The DNS TXT records indicate integrations with major platforms such as Salesforce, Microsoft, and Adobe, suggesting a mature IT ecosystem.

Security posture

The security posture is currently poor due to the absence of a valid SSL certificate and disabled TLS protocols, which are critical for secure communications. While security headers like Content Security Policy, Referrer Policy, and Permissions Policy are configured, their benefits are negated by the lack of HTTPS. The presence of a WAF indicates an effort to protect the site, but the current configuration results in legitimate user access being blocked. No vulnerabilities such as Heartbleed or POODLE were detected, but the invalid SSL is a critical issue. Incident response and security policy information are not publicly available.

Recommendations

  1. Obtain and deploy a valid SSL/TLS certificate immediately to enable HTTPS and secure user connections.
  2. Enable support for modern TLS protocols (TLS 1.2 and TLS 1.3) to improve security and compatibility.
  3. Review and adjust WAF rules to prevent blocking legitimate users and ensure proper access to website content.
  4. Publish clear privacy, cookie, and terms of service policies to improve compliance and user trust.
  5. Implement and publicize incident response and vulnerability disclosure policies to enhance security posture and transparency.
Technical notes

Notes

The website is hosted behind Akamai, a reputable CDN and security provider. DNS records are well configured with multiple authoritative name servers and MX records for email. However, the SSL configuration is invalid, with no supported TLS versions detected, which is a critical technical deficiency. No CMS or frameworks could be detected due to lack of accessible content. Performance metrics are unavailable due to the access denial. The site uses security headers effectively but cannot leverage them fully without valid HTTPS. The technical infrastructure shows potential but requires remediation of SSL and access issues to improve operational reliability and security.
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.
