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

3 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

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

Sparteo operates in the technology and media sectors, focusing on B2B services for publishers and advertising networks. Their business model revolves around providing SaaS platforms and technology solutions that optimize advertising revenue while ensuring regulatory compliance. The company has a medium-sized footprint with multiple subsidiary brands such as Actirise, FastCMP, Meetscale, Viously, and Voxeus, each targeting specific niches within the advertising ecosystem. Sparteo's competitive advantage lies in its AI-driven optimization, carbon-neutral infrastructure, and comprehensive compliance tools. The company actively promotes transparency and trust through certifications and industry awards. Their partnership ecosystem includes several specialized platforms, enhancing their market reach and service diversity. Growth indicators include recent news articles highlighting product enhancements and market achievements.

Security posture

Sparteo exhibits a strong security posture with HTTPS enabled site-wide, implementation of security headers like Content-Security-Policy and Strict-Transport-Security, and integration of Google reCAPTCHA to protect forms. The use of FastCMP for consent management indicates a commitment to privacy compliance and regulatory adherence. No exposed sensitive data or vulnerable libraries were detected in the website content. However, the absence of a dedicated security policy page and incident response contact information suggests areas for improvement in transparency and readiness. There is no evidence of a vulnerability disclosure program or security.txt file, which could enhance the company's security culture and external communication. Overall, Sparteo maintains a secure environment appropriate for its business operations but could benefit from formalizing some security governance aspects.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and compliance.
  2. Provide clear incident response contact channels such as security@ or abuse@ email addresses.
  3. Implement a vulnerability disclosure program and publish a security.txt file.
  4. Enhance accessibility features to improve inclusivity and compliance with standards.
  5. Regularly review and audit third-party scripts and dependencies for vulnerabilities.

Technical notes

Notes

The website is built on the Webflow platform, utilizing modern front-end technologies and libraries such as Swiper.js for sliders and Matomo for analytics. The site is well-optimized for performance and mobile responsiveness, with clean, semantic HTML and CSS. The use of FastCMP indicates an advanced approach to consent management and privacy compliance. Hosting is provided by Webflow, ensuring reliable uptime and scalability. The technical stack supports a professional and user-friendly experience, though opportunities exist to enhance accessibility and formalize security documentation. The integration of multiple partner platforms is seamless, reflecting a mature technical infrastructure capable of supporting complex AdTech services.
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.
