Synapse Développement is a French technology company specializing in AI consulting, deployment, and training services. With over 20 years of experience, they position themselves as pioneers in AI solutions tailored to business needs, focusing on knowledge capital valorization. Their website showcases multiple AI-driven products and services such as Dearbot, Cordial, Semantics, and AI training programs, targeting enterprises seeking to leverage AI for operational performance improvements. The company uses a modern WordPress-based infrastructure with Elementor and Yoast SEO plugins, supported by OVH hosting. The site is well-structured, mobile-optimized, and integrates Google Analytics and Tag Manager for tracking. Security posture is solid with HTTPS enabled, but lacks some security headers and visible privacy/cookie policies, indicating room for compliance improvements. No contact emails or phone numbers are explicitly listed, relying on contact forms for communication. Overall, the domain registration data is consistent and legitimate, supporting the company's credibility. Strategic recommendations include enhancing privacy compliance, adding security headers, and publishing incident response and vulnerability disclosure information.

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

7 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

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  3. 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

Synapse operates in the AI technology sector, offering bespoke AI solutions and training primarily to business clients. Their market positioning as a pioneer with 20 years of experience provides a competitive advantage. The business model is B2B consulting and software-as-a-service with a focus on AI integration and knowledge management. Revenue streams likely include consulting fees, software licenses, and training programs. The target customer segment includes enterprises seeking AI transformation. The company maintains a professional online presence with case studies and resources to support client acquisition and retention. Partnerships or subsidiaries are not explicitly identified. The company leverages modern web technologies and SEO to maintain visibility and engagement.

Security posture

The website demonstrates a good security baseline with HTTPS enforced and no visible sensitive data exposure. However, the absence of key security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces defense-in-depth. No vulnerability disclosure or incident response information is provided, which is a gap in security transparency. The use of third-party scripts like Google Analytics and Tag Manager is standard but requires ongoing monitoring for vulnerabilities. The lack of explicit privacy and cookie policies may expose the company to compliance risks under GDPR. Overall, the security posture is moderate with clear areas for improvement to enhance trust and compliance.

Recommendations

  1. Publish comprehensive privacy and cookie policies with clear GDPR compliance statements.
  2. Implement security headers including CSP, HSTS, and X-Frame-Options to strengthen security posture.
  3. Add explicit contact information including company emails and phone numbers to improve trust and accessibility.
  4. Establish and publish a vulnerability disclosure policy and incident response contact to enhance security transparency.
  5. Conduct regular security audits of third-party scripts and update them to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built on WordPress with Elementor page builder and Yoast SEO plugin, indicating a modern and flexible CMS environment. It uses Google Tag Manager and Google Analytics for tracking, and Splide.js for carousel functionality. Hosting is provided by OVH, a reputable provider. The site is mobile-optimized and uses responsive design principles. Performance is moderate, with lazy loading for images and asynchronous script loading. Accessibility features are basic but present. SEO is well addressed with meta tags, Open Graph, and JSON-LD structured data. Technical risks include missing security headers and potential compliance gaps due to absent privacy and cookie policies. The infrastructure is solid but could benefit from enhanced security and privacy controls.
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.
