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

Legrand is a global specialist in electrical and digital building infrastructures, offering a wide range of products and solutions tailored for various countries and global markets. The company positions itself as a leader in its industry, targeting both B2B and B2C customers seeking advanced electrical infrastructure solutions. The website reflects a professional and consistent brand image with good content quality and clear navigation, although some key contact information is not directly visible on the landing page. Technically, the website is built on Drupal 10 and leverages modern technologies such as Google Tag Manager and tarteaucitron.js for cookie consent management, hosted via Amazon CloudFront CDN. While the site shows basic mobile optimization and accessibility features, performance data is unavailable. SEO optimization is basic but present through meta tags and Open Graph data. From a security perspective, the site implements several important HTTP security headers and a content security policy. However, the lack of a valid SSL certificate and absence of TLS protocols severely undermine the security posture, exposing users to risks and reducing trust. No vulnerabilities like Heartbleed or POODLE were detected, but the SSL misconfiguration is a critical issue. Overall, the website demonstrates moderate digital maturity and business credibility but requires urgent remediation of SSL issues to improve security and user trust. Privacy compliance is good with clear cookie consent mechanisms and GDPR-aligned policies. Strategic improvements in security infrastructure and enhanced contact transparency would strengthen the company's online presence and risk posture.

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. 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 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

Legrand operates as an essential entity within the energy sector, specializing in electrical and digital building infrastructures. Its business model focuses on providing comprehensive infrastructure solutions globally, supported by country-specific websites and global solution portals. The company benefits from a strong market position as a global specialist, leveraging a consistent brand and professional content to engage a broad target audience. The use of Drupal CMS and integration with major analytics and marketing tools indicates a mature digital ecosystem. However, the absence of visible contact information and terms of service on the landing page suggests areas for improved customer engagement and transparency. The WHOIS data confirms the domain's legitimacy and alignment with the company's identity, supporting trustworthiness in the market.

Security posture

The website's security posture is mixed. It benefits from well-configured security headers including CSP, X-Frame-Options, and HSTS directives. The presence of a cookie consent mechanism and GDPR compliance indicators further enhance privacy protections. However, the critical failure to deploy a valid SSL certificate and enable TLS protocols severely compromises secure communications, exposing users to potential interception and undermining trust. No major vulnerabilities or malware indicators were found, but the lack of HTTPS is a critical security gap. Incident response and security policy information are not publicly available, indicating limited transparency in security governance. Overall, the site requires immediate SSL remediation and ongoing security monitoring to meet enterprise security standards.

Recommendations

  1. Urgently fix the SSL certificate to enable valid HTTPS and TLS 1.2+ protocols.
  2. Implement strong cipher suites and enable OCSP stapling and session resumption for improved SSL performance and security.
  3. Publish clear contact information including security incident response contacts and update terms of service.
  4. Enhance privacy compliance by providing explicit data retention policies and a dedicated data protection officer contact.
  5. Regularly audit and update security headers and content security policies to mitigate emerging threats.
Technical notes

Notes

The website is built on Drupal 10 CMS, leveraging modern JavaScript libraries and hosted on Amazon CloudFront CDN, indicating a robust and scalable infrastructure. It uses Google Tag Manager and tarteaucitron.js for analytics and cookie consent management, reflecting compliance with privacy regulations. The site includes preconnect hints for performance optimization and uses Google Fonts for typography. However, performance metrics are unavailable, and mobile optimization is basic. The invalid SSL certificate and lack of TLS support represent significant technical debt and risk. The site’s SEO is basic but includes Open Graph metadata for social sharing. Accessibility features are minimal but present. Overall, the technical stack is modern but requires urgent security improvements and performance monitoring.
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.
