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

SIDO LYON operates as a leading European event and showroom specializing in IoT, Artificial Intelligence, Robotics, and Extended Reality technologies. The website presents a professional and well-structured platform targeting industry professionals and companies interested in these advanced technology sectors. The business model centers around organizing and showcasing innovative technology solutions, positioning itself as a key player in the European technology event market. Technically, the website is built on WordPress CMS, leveraging popular plugins such as Contact Form 7 and Yoast SEO, alongside marketing and analytics tools including Google Tag Manager, Google Ads, and LiveChat. The site demonstrates good mobile optimization and SEO practices, with GDPR compliance implemented via the Didomi consent management platform. Performance is moderate, with room for improvement in accessibility and security headers. From a security perspective, the site enforces HTTPS with strong SSL configuration and integrates GDPR consent mechanisms. However, the absence of explicit security headers and lack of published security policies or incident response contacts indicate areas for enhancement. The missing WHOIS data for the domain raises concerns about domain registration legitimacy, although the active and professional website presence suggests a legitimate business operation. Overall, SIDO LYON presents a credible and professional digital presence with solid business positioning in the technology event sector. Strategic improvements in security transparency, domain registration verification, and contact information disclosure would further strengthen trust and compliance.

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

6 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 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 Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Twitter, LinkedIn, YouTube

      What to do: Document all third-party data sharing in your privacy policy

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

SIDO LYON holds a prominent position as a technology event organizer focusing on IoT, AI, Robotics, and XR sectors. Its competitive advantage lies in being the largest European showroom for these technologies, attracting a professional audience. The business model is event-driven, generating revenue through exhibitions and partnerships. The target customers are technology companies and professionals seeking exposure and networking opportunities. The website's integration of marketing tools and GDPR compliance reflects a mature digital strategy. Partnerships and ecosystem details are not explicitly found, suggesting potential for growth in strategic alliances. The company's operations appear medium-sized with consistent branding and good content quality.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and GDPR consent management in place. However, the absence of key security headers such as Content Security Policy, HSTS, and X-Frame-Options reduces the overall security posture. No vulnerabilities or exposed sensitive data were detected in the provided content. Compliance with GDPR is evident, but incident response readiness and security policy transparency are lacking. The missing WHOIS data for the domain is a notable risk factor, potentially impacting trustworthiness. Overall, the security culture appears functional but could benefit from enhanced policies and technical controls.

Recommendations

  1. Implement and publish a comprehensive security policy and incident response contact information on the website.
  2. Add essential security headers including Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options to improve protection against common web attacks.
  3. Verify and update domain WHOIS information to ensure transparency and legitimacy of domain registration.
  4. Disclose clear company contact emails and phone numbers to enhance business credibility and user trust.
  5. Establish a vulnerability disclosure program or security.txt file to facilitate responsible reporting of security issues.

Technical notes

Notes

The website is built on a WordPress platform using standard plugins for forms, SEO, and consent management. It employs jQuery and integrates Google Tag Manager and Google Ads for analytics and marketing. The presence of LiveChat indicates active customer engagement. Performance is moderate with good mobile responsiveness. Accessibility features are basic and could be improved. The site uses HTTPS with a strong SSL configuration but lacks some modern security headers. The technical stack is typical for a medium-sized event website, with opportunities to modernize and enhance security and accessibility.
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.
