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

Probabl is a technology company founded in 2023 in France, focusing on open source commons for AI, machine learning, and data science. The company leverages the expertise of scikit-learn co-founders and core developers to provide collaboration tools, training platforms, and enterprise AI support services. Their market position is niche but credible due to strong ties with the scikit-learn community and open source ecosystem. Technically, the website is built on Webflow with HubSpot integration for forms and analytics, hosted on Scaleway infrastructure. The site is well-designed, mobile-optimized, and provides a good user experience with clear navigation and relevant content. Security posture is adequate with HTTPS and domain transfer protection, but lacks DNSSEC and explicit security headers. Privacy compliance is basic with a privacy policy present but no cookie consent mechanism. Contact information is limited to forms without direct emails or phone numbers. Overall, the website is professional and trustworthy but could improve in security and privacy transparency.

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. 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 Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • High

      Third-party services without privacy policy

      Detected services: LinkedIn, YouTube, Google APIs

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

  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

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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.

Dark web exposure

Add-on

Leaked records that mention probabl.ai, from OffSeq Breach.

No leaked records found

Breach holds no records for probabl.ai right now. New leaks arrive continuously, so monitoring on Breach alerts you if that changes.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

Probabl operates in the technology sector, targeting data scientists, AI practitioners, and enterprises requiring AI solutions. Their business model combines open source commons with professional services and training. The company benefits from its association with scikit-learn founders, enhancing its competitive advantage and market credibility. The presence of multiple subdomains for partnerships, papers, and recruitment indicates a growing ecosystem. Marketing relies on HubSpot tools and social media channels including LinkedIn, Discord, YouTube, and Bluesky. The company is small-sized and relatively new, with a focus on innovation and community engagement.

Security posture

The security maturity level is moderate. The website enforces HTTPS and has domain status clientTransferProhibited, which protects against unauthorized domain transfers. However, DNSSEC is not enabled, and no explicit security headers (such as CSP, HSTS, or X-Frame-Options) were detected in the HTML content. There is no published security policy or incident response information, and no vulnerability disclosure or security.txt file was found. Forms are secured via HubSpot, but no direct contact for security incidents is provided. Privacy compliance is partial, lacking cookie consent mechanisms. Overall, the security posture is adequate for a small technology company but could be enhanced to meet higher compliance and security standards.

Recommendations

  1. Enable DNSSEC to improve domain security and prevent DNS spoofing.
  2. Implement and publish a comprehensive security policy and incident response plan.
  3. Add standard security headers (CSP, HSTS, X-Frame-Options) to enhance web security.
  4. Introduce a cookie consent banner to comply with GDPR and improve privacy transparency.
  5. Provide direct contact information for security incidents, such as a security@ or abuse@ email address.

Technical notes

Notes

The website uses modern web technologies including Webflow CMS, HubSpot for forms and analytics, Google Fonts, and jQuery. Hosting is provided by Scaleway, indicated by the DNS name servers. Performance is moderate with good mobile optimization and basic accessibility features. SEO is supported by proper meta tags and Open Graph data. The site integrates interactive elements and animations via Lottie and Reo.js. Technical debt appears low, but improvements can be made in security headers and privacy mechanisms. The infrastructure is suitable for a small to medium-sized technology company with room for scaling and modernization.
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.
