Risk levelMedium

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

The Jekill & Hyde Company bv operates a niche business specializing in electronically adjustable motorcycle exhaust systems, targeting motorcycle enthusiasts primarily in the Netherlands. Their website offers a brand selector configurator tool, emphasizing product customization, performance, quality, and legal compliance. The company positions itself as a quality-focused manufacturer with a direct-to-consumer sales model. Technically, the website employs a modern JavaScript stack including jQuery, Select2, Hammer.js, and integrates marketing and analytics tools such as Klaviyo, Google Tag Manager, and Facebook Pixel. Cookie consent is managed via Cookiebot with TCF v2.2 compliance, indicating attention to privacy regulations. However, no explicit privacy or terms of service pages were found in the provided content. Security posture shows some strengths like CSRF token usage and HTTPS implied by external scripts, but lacks visible security headers and explicit security policies. WHOIS data is missing, which is unusual and reduces domain trustworthiness, though the website content and contact information appear legitimate. Overall, the site is professionally designed, mobile optimized, and provides clear contact details, but could improve transparency and security 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. 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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 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

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 targets a specialized segment within the motorcycle aftermarket industry, focusing on electronically adjustable exhaust systems. Their competitive advantage lies in product customization and legal compliance, appealing to performance-conscious riders. The business model appears to be direct sales supported by digital marketing and analytics tools. The presence of multiple tracking and marketing platforms suggests an active customer acquisition strategy. The lack of WHOIS data and privacy policy pages may indicate areas for operational improvement. No partner or subsidiary domains were identified, suggesting a standalone operation. The company is small-sized and based in the Netherlands, with a clear physical address and contact information enhancing credibility.

Security posture

The website demonstrates moderate security maturity. HTTPS is implied but not explicitly confirmed in the data. The use of CSRF tokens in AJAX requests and cookie consent mechanisms are positive indicators. However, the absence of security headers such as Content-Security-Policy, HSTS, and X-Frame-Options is a notable gap. No vulnerability disclosures or incident response contacts are provided, limiting transparency in security management. The missing WHOIS data raises questions about domain registration transparency. Overall, the security posture is functional but could be significantly improved by implementing standard security headers, publishing privacy and security policies, and providing incident response information.

Recommendations

  1. Implement and verify comprehensive HTTP security headers including CSP, HSTS, X-Frame-Options, and X-XSS-Protection.
  2. Publish a clear and comprehensive privacy policy and terms of service pages accessible from the website.
  3. Ensure SSL/TLS configuration is strong and visible to users (e.g., via HTTPS and security seals).
  4. Add incident response and vulnerability disclosure information to improve transparency and trust.
  5. Review domain registration details and ensure WHOIS information is accurate and publicly available to enhance legitimacy.

Technical notes

Notes

The website uses a modern JavaScript-based front-end stack with libraries such as jQuery, Select2, Hammer.js, and Lottie for animations. Marketing and analytics integrations include Klaviyo, Google Tag Manager, Facebook Pixel, and Mailchimp, indicating a mature digital marketing setup. Cookie consent is managed via Cookiebot with compliance to IAB TCF v2.2 standards. The site is mobile optimized and uses structured data (JSON-LD) for local business information, aiding SEO. Performance is moderate with asynchronous loading of scripts. No CMS or hosting provider information was detected. Security headers are missing, representing a technical risk. The site could benefit from improved accessibility features and enhanced SEO metadata completeness.
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.
