Bostik is a global leader in adhesive technologies serving diverse sectors such as construction, automotive, aerospace, packaging, and DIY markets.

The website reflects a mature enterprise with a strong market position and a focus on sustainability and innovation. Technically, the site employs modern analytics and consent management tools, is built on the Jahia CMS platform, and is hosted with Cloudflare, ensuring good performance and security. Security posture is strong with HTTPS, security headers, and privacy compliance evident, although explicit incident response and vulnerability disclosure information are not found.

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. 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';…
  2. 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

  3. 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 SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

Bostik operates in the manufacturing sector, focusing on adhesive solutions for industrial, construction, and consumer markets. Its business model combines B2B and B2C approaches, leveraging innovation and sustainability as competitive advantages. The company benefits from its parent company Arkema's global presence and resources. The website's multilingual support and extensive product and market information indicate a broad target audience and a well-established global footprint. The presence of training and academy resources suggests investment in customer education and support. The company maintains active social media channels and publishes corporate news, enhancing transparency and engagement.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, comprehensive security headers, and consent management for privacy compliance. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of explicit incident response contact details and vulnerability disclosure policies represents an area for improvement. The site aligns with GDPR compliance through privacy and cookie policies. Overall, the security measures are robust for a corporate website, minimizing risk exposure and supporting trustworthiness.

Recommendations

  1. Publish explicit incident response and security contact information to improve transparency and readiness.
  2. Implement and publicize a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  3. Enhance visibility of security certifications or compliance frameworks to strengthen trust signals.
  4. Regularly review and update third-party scripts and tracking tools to minimize privacy risks.
  5. Continue investment in accessibility and mobile optimization to improve user experience and compliance.

Technical notes

Notes

The website is built on the Jahia CMS platform and uses a modern technology stack including Google Tag Manager, Piwik PRO analytics, Day.js for date handling, Kameleoon for personalization, and Didomi for consent management. Hosting is via Cloudflare, providing CDN and security benefits. The site shows good mobile optimization, accessibility features, and SEO best practices. Performance is moderate, with asynchronous loading of scripts and optimized assets. The technical infrastructure supports a professional and scalable digital presence, though continuous monitoring of third-party dependencies is advised to mitigate potential risks.
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.
