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.

    • 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.

    • 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
    • High

      SSL Certificate Expires Soon

      SSL certificate expires in 28 days

      What to do: Renew SSL certificate before expiration

      • NIS2 21(2)(h)
      • IR 2024/2690 9.2(c): Implementing Regulation (EU) 2024/2690, Annex point 9.2(c): Cryptography
      • NIST SC-17: NIST SP 800-53 Rev. 5 SC-17: Public Key Infrastructure Certificates

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

Business profile

Sparteo operates in the AdTech sector, targeting publishers and ad networks with a B2B SaaS model. Their competitive advantage lies in AI-powered advertising technologies and a comprehensive suite of solutions covering monetization, consent management, and media formats including video and audio. The company has a medium-sized footprint with multiple subsidiaries and partnerships, and is recognized by industry awards and certifications. Their market positioning is strong in France and Europe, with offices in key cities and a focus on sustainable and privacy-compliant advertising. The business model emphasizes alignment with publisher success and regulatory compliance, which is a critical factor in the evolving digital advertising landscape.

Security posture

The website demonstrates a good security maturity level with HTTPS and reCAPTCHA integration. Consent management is handled by FastCMP, indicating attention to privacy regulations such as GDPR. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of explicit HTTP security headers like Content-Security-Policy or X-Frame-Options suggests room for improvement. There is no public incident response or vulnerability disclosure information, which could be enhanced to improve security transparency. Overall, the security posture is solid but could benefit from additional best practices and public security policies.

Recommendations

  1. Implement and verify HTTP security headers such as CSP, HSTS, and X-Frame-Options to enhance protection against common web attacks.
  2. Publish a security.txt file to provide clear vulnerability disclosure and incident response contact information.
  3. Enhance transparency on data retention policies and update privacy documentation accordingly.
  4. Regularly audit third-party scripts and dependencies to ensure no vulnerable libraries are included.
  5. Consider adding explicit security and incident response policies on the website to build trust with customers and partners.

Technical notes

Notes

The website is built using Webflow CMS, leveraging modern front-end technologies including Swiper.js for sliders and Matomo for analytics. Google reCAPTCHA is used for bot protection. Hosting appears to be via AWS Cloudfront CDN, ensuring fast content delivery. The site is mobile-optimized with responsive design and good accessibility features. SEO is supported by proper meta tags and Open Graph data. The technical implementation is modern and performant, with no broken elements detected. Opportunities exist to improve security headers and provide more detailed technical documentation for security and privacy.
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.
