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

The website www.ceresit-coloursofnature.cz serves as a digital platform for Henkel's Ceresit brand, focusing on facade colors and plasters inspired by nature. It provides users with interactive tools such as facade designers, color tests, and photo-based color finders to personalize their home exteriors. The site targets homeowners, architects, and designers seeking aesthetic and functional facade solutions. The business model centers on product marketing and customer engagement through digital experiences, reinforcing Henkel's market position in the construction and building materials sector. Technically, the website employs modern web technologies including HTML5, CSS3, JavaScript, and integrates Google Analytics and Tag Manager for analytics, alongside OneTrust for cookie consent management. The site is mobile-optimized, accessible, and demonstrates good SEO practices. Performance is moderate with room for optimization. Security posture is solid with HTTPS enforced and cookie consent mechanisms in place, though security headers could be enhanced. From a security and compliance perspective, the site includes comprehensive privacy and cookie policies, indicating GDPR compliance. However, no explicit security policy, incident response contacts, or vulnerability disclosure mechanisms were found. WHOIS data is unavailable, likely due to privacy protection, which is common for corporate websites. No suspicious content or vulnerabilities were detected. Overall, the website presents a professional, trustworthy, and user-friendly experience aligned with Henkel's brand standards. Strategic recommendations include enhancing security headers, publishing security policies, and providing direct contact information for security incidents to improve transparency and trust.

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. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

    • High

      No SPF record found

      SPF helps prevent email spoofing

      What to do: Add SPF record: "v=spf1 include:_spf.yourmailprovider.com ~all"

  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.

Business context

Business profile

Henkel's Ceresit brand leverages this website to strengthen its market presence in facade materials by offering a rich palette of colors and design tools. The platform supports customer engagement and brand loyalty through interactive features and inspirational content. The absence of direct contact emails or phone numbers suggests a focus on digital self-service and brand-controlled communication channels. The website's integration with Henkel's main domain and consistent branding underscores a strong corporate identity. Growth opportunities include expanding multilingual support and integrating e-commerce capabilities. The partnership ecosystem is limited to Henkel's corporate structure, with no external affiliates detected.

Security posture

The website demonstrates a mature security posture with enforced HTTPS and a robust cookie consent framework compliant with GDPR. The absence of security headers such as Content-Security-Policy and X-Frame-Options represents an area for improvement. No exposed sensitive data or vulnerable libraries were identified. The lack of a published security policy or incident response contact reduces transparency and may impact user trust. No vulnerability disclosure or security.txt files were found, limiting external security collaboration. Overall, the site is secure for general users but could enhance its security culture and incident readiness.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a clear security policy and incident response contact information on the website.
  3. Introduce a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  4. Enhance transparency by providing direct contact emails or phone numbers for security and privacy inquiries.
  5. Optimize website performance and accessibility further to improve user experience and SEO.

Technical notes

Notes

The website is built with standard modern web technologies and integrates third-party analytics and cookie management tools effectively. It is mobile-responsive and accessible, with a clean and professional design. The use of Google Tag Manager and Analytics indicates a data-driven approach to user engagement. However, the site lacks some advanced security headers and detailed technical metadata such as structured data (JSON-LD) or Open Graph tags, which could improve SEO and social media integration. Hosting details are not explicitly identified. Performance is moderate, suggesting potential for optimization in loading times and resource management.
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.
