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

Trombi.com is a French online platform dedicated to helping users reconnect with former school friends, access a large archive of class photos, and organize class reunions. The website targets alumni and former students primarily in France, offering free registration and a searchable database of over 13 million users. The business operates in the education sector with a social networking focus, leveraging advertising as a primary revenue stream. The site is professionally designed with consistent branding and provides comprehensive privacy and cookie policies compliant with GDPR regulations. Technically, Trombi.com uses a moderate technology stack including jQuery, Bootstrap, and Google Tag Manager, with some older frameworks but overall functional and moderately optimized for performance and SEO. Security posture is adequate with HTTPS usage and privacy consent mechanisms, though security headers and explicit incident response information are lacking. The absence of WHOIS data for the domain introduces some uncertainty about domain registration legitimacy, but the active and professional website presence supports a moderate trust level. Overall, Trombi.com presents a solid business offering with room for technical and security improvements.

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. 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';…

  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 platform holds a strong position in the French alumni social networking niche, with a large user base and extensive class photo archives. Its business model relies on advertising and user engagement through reunion organization features. The presence of related StayFriends domains in multiple European countries suggests a broader partnership or group affiliation, enhancing market reach. The company, Trombi Acquisition Sarl, appears to be a medium-sized entity focused on education and social networking. The lack of direct contact information on the site may limit user trust and support accessibility. Growth opportunities include expanding mobile optimization and enhancing security transparency. The advertising ecosystem is integrated but could benefit from improved transparency and user control.

Security posture

Trombi.com demonstrates a moderate security maturity level with HTTPS enforced and GDPR-compliant privacy and cookie policies. The use of third-party ad and tracking scripts introduces potential privacy risks, mitigated by consent management tools. However, the absence of key security headers such as Content Security Policy, HSTS, and X-Frame-Options reduces defense-in-depth. No visible vulnerabilities or exposed sensitive data were detected in the HTML content. The lack of published security policies or incident response contacts indicates a gap in security governance and transparency. Overall, the site is reasonably secure for its business type but should enhance security headers, incident response readiness, and third-party script auditing to improve resilience and user trust.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, and X-Frame-Options to strengthen browser security.
  2. Publish explicit security policy and incident response contact information to improve transparency and user confidence.
  3. Enhance mobile optimization and accessibility features to improve user experience across devices.
  4. Regularly audit and update third-party scripts to mitigate risks from advertising and tracking services.
  5. Verify and publish domain registration details to resolve WHOIS inconsistencies and reinforce legitimacy.

Technical notes

Notes

The website employs a moderately modern technology stack with jQuery 3.7.1, Bootstrap 3.3.1, and Font Awesome 4.7.0. Google Tag Manager is used for analytics and marketing, alongside Ströer ad network scripts and privacy management SDKs. The site is served over HTTPS with canonical URLs indicating secure access. Performance is moderate with room for improvement in mobile responsiveness and accessibility. No CMS is explicitly detected, suggesting a custom or proprietary platform. The site structure and meta tags support good SEO practices. Technical debt is indicated by older Bootstrap and Font Awesome versions. Hosting provider details are not discernible from the HTML content. Overall, the technical infrastructure supports the business needs but could benefit from modernization and enhanced security configurations.
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.
