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

SIS Marchés is a French specialist software provider focused on public procurement management, operating as a subsidiary of the Ach@t Solutions group. The company offers a modular, collaborative software suite designed to streamline and secure public purchasing processes for buyers and suppliers. Their market position is strong within the French public sector, supported by over 450 clients and a broad user base. The website reflects a professional and consistent brand image, targeting public sector buyers and private suppliers with a comprehensive digital solution portfolio. Technically, the site is built on Drupal 8 with modern frontend libraries and integrates multiple marketing and analytics tools, indicating a mature digital infrastructure. Security posture is good with HTTPS enforced and cookie consent implemented, though explicit security headers and policies are lacking. The absence of WHOIS data for the domain is a notable concern, reducing trust in domain legitimacy despite the professional business presence. Overall, the website and business appear credible and well-established, but domain registration transparency should be improved.

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

5 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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

      Third-party services without privacy policy

      Detected services: Google Analytics, Twitter, LinkedIn, Google APIs

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

  3. 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.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

The company operates in the government and technology sectors, providing essential software solutions for public procurement. Their business model revolves around software licensing and service provision to public entities and suppliers. The parent group, Ach@t Solutions, is a growing entity with multiple subsidiaries, indicating a diversified portfolio and strong market presence. The website highlights client trust and references, reinforcing market credibility. Growth indicators include a significant user base and investment in R&D. Partnerships and subsidiary domains are well integrated, supporting a cohesive ecosystem. The company targets public sector organizations and suppliers, focusing on compliance, collaboration, and digital transformation.

Security posture

The website demonstrates a moderate to good security maturity level with HTTPS enforced and cookie consent mechanisms aligned with GDPR. However, the lack of visible security headers such as Content Security Policy, HSTS, and X-Frame-Options reduces the overall security posture. No explicit security policies, incident response contacts, or vulnerability disclosure information are published, which are best practices for transparency and readiness. The use of multiple third-party tracking scripts introduces potential privacy and security risks that should be regularly audited. No obvious vulnerabilities or exposed sensitive data were detected in the HTML content. The missing WHOIS data for the domain is a risk factor for trust and domain legitimacy.

Recommendations

  1. Implement and publish a comprehensive security policy and incident response contact information on the website.
  2. Add and enforce security headers such as Content Security Policy, HSTS, X-Frame-Options, and X-Content-Type-Options to enhance protection.
  3. Publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting and transparency.
  4. Regularly audit and minimize third-party tracking scripts to reduce privacy risks and improve compliance.
  5. Investigate and resolve the missing WHOIS data issue to improve domain registration transparency and trustworthiness.

Technical notes

Notes

The website is built on Drupal 8 CMS, leveraging jQuery, Bootstrap 3.4.1, and FontAwesome 5 for frontend functionality and styling. It integrates Google Tag Manager, Google Analytics, Facebook SDK, and Twitter widgets for marketing and analytics purposes. The site is mobile optimized with responsive design and includes accessibility features, though these could be enhanced. Performance is moderate, with no major issues detected. The technical stack is modern but could benefit from updated Bootstrap and jQuery versions for improved security and performance. The hosting provider is not explicitly identified. Overall, the technical implementation supports a professional and functional user experience but has room for modernization and security hardening.
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.
