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

Essilor is a global leader in the healthcare sector specializing in prescription lenses and vision care products. The company offers a wide range of innovative lenses designed to correct, protect, and enhance vision, targeting consumers seeking high-quality vision solutions. Their website demonstrates a strong market position with comprehensive product offerings, digital tools for lens personalization, and a store locator for partnered opticians. Technically, the site is built on modern frameworks such as React and Next.js, hosted likely on Microsoft Azure, and optimized for fast performance and excellent mobile experience. Security posture is strong with robust HTTP security headers and a valid SSL certificate, although the absence of enabled TLS protocols and DNS security features are notable gaps. Privacy policies and terms of service are present and comprehensive, but cookie consent mechanisms and vulnerability disclosure policies are lacking. Overall, the website reflects a mature digital presence with room for security enhancements and improved transparency in user consent.

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.

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

Essilor operates in the healthcare industry focusing on vision correction and protection. Their business model revolves around manufacturing and retailing advanced prescription lenses and related vision care products. The company targets consumers globally who require vision correction solutions, leveraging innovation such as AI-powered lenses. Their competitive advantage lies in their market leadership, product innovation, and extensive optician partnerships. Revenue streams likely include direct sales through opticians and digital tools for lens customization. The company maintains a strong brand presence supported by consistent branding and trust indicators such as secure website practices and social media engagement. Growth is supported by continuous product innovation and digital transformation initiatives.

Security posture

The website demonstrates a high level of security maturity with strict transport security, XSS protection, content security policies, and frame options configured to prevent common web attacks. The SSL certificate is valid and issued by a reputable authority. However, the lack of enabled TLS protocols is a critical issue that could impact secure communications. DNSSEC and CAA records are not implemented, which reduces domain security. There is no visible incident response or vulnerability disclosure information, which could hinder timely security issue reporting. Privacy compliance is strong with GDPR-aligned policies, but cookie consent mechanisms are absent. Overall, the security posture is robust but requires improvements in protocol support and transparency.

Recommendations

  1. Enable TLS 1.2 and TLS 1.3 protocols to ensure secure encrypted communications.
  2. Implement DNSSEC and CAA DNS records to enhance domain security and certificate issuance control.
  3. Add a cookie policy with explicit user consent mechanisms to comply with privacy regulations.
  4. Publish a security.txt file or dedicated vulnerability disclosure page to facilitate responsible reporting.
  5. Enhance contact information visibility including security contact emails for incident response.
Technical notes

Notes

The website is built using React and Next.js frameworks, indicating a modern and scalable front-end architecture. The use of server-side rendering improves SEO and performance. Hosting appears to be on Microsoft Azure, supported by DNS and mail exchange records. Performance metrics indicate fast load times and excellent mobile optimization. Accessibility and SEO are well addressed through proper metadata, Open Graph tags, and structured content. However, the absence of enabled TLS protocols is a technical risk. The site uses a custom CMS for content management and integrates marketing tools such as Brevo. Overall, the technical infrastructure is modern and robust with minor security protocol gaps.
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.
