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

The website www.kerastase.com/hair-salon-locator serves as a professional hair salon locator for the Kérastase brand, a premium hair care line under the L'Oréal Group. It targets consumers seeking expert hair diagnosis and tailored hair and scalp care routines. The site leverages modern web technologies including Vue.js and Google Maps API to provide an interactive and user-friendly experience. The presence of OneTrust cookie consent indicates attention to privacy compliance, although no explicit privacy policy or terms of service were found on the analyzed page. Security posture is moderate with HTTPS implied but lacking visible security headers and vulnerability disclosures. WHOIS data for the domain is unavailable, which raises some concerns about domain registration legitimacy, but the branding and content align with the known Kérastase brand, suggesting authenticity. Overall, the site is professionally designed, mobile-optimized, and provides relevant services to its target audience.

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

2 findings rated critical or high. Fix these first.

  1. 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

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  2. 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 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';…

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

Kérastase operates in the retail sector focusing on premium hair care products and professional salon services. The business model includes product sales and providing consumers with access to authorized salons via the locator tool. The website supports brand positioning as a leader in luxury hair care. The lack of visible direct contact information on this page suggests customer engagement may be handled elsewhere or through partner salons. The integration of Google Analytics and Tag Manager supports marketing and user behavior analysis. The absence of WHOIS data is unusual for a large brand and may indicate domain privacy or a proxy registration. No affiliate or partner domains were identified from this page.

Security posture

The website uses HTTPS and includes a cookie consent mechanism, indicating baseline security and privacy awareness. However, no security headers such as Content-Security-Policy or X-Frame-Options were detected, and no vulnerability disclosure or security.txt files were found. The site uses third-party scripts including Google Analytics and OneTrust, which should be regularly audited for security. The absence of visible contact information for incident response or data protection officers limits transparency. Overall, the security posture is moderate but could be improved with enhanced headers, explicit policies, and vulnerability disclosure mechanisms.

Recommendations

  1. Implement and publish a comprehensive privacy policy and terms of service accessible from all pages.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to enhance protection.
  3. Publish a security.txt file and provide clear incident response contact information to improve transparency and trust.
  4. Verify and update WHOIS domain registration information to ensure consistency and legitimacy.
  5. Regularly audit third-party scripts and tracking tools to minimize security risks and ensure privacy compliance.

Technical notes

Notes

The website is built using Vue.js 2.7.16, leveraging Google Maps API for salon location services. It uses OneTrust for cookie consent management and Google Analytics and Tag Manager for analytics and marketing. The site appears mobile-optimized with responsive design elements. Performance is moderate, with no explicit CMS detected. The technical implementation is modern but could benefit from improved accessibility features and enhanced security configurations. Hosting provider details are not evident from the provided data.
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.
