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

The website https://particuliers.sg.fr/ represents Société Générale's retail banking and insurance services, targeting individual customers primarily in France. It serves as a portal for account access and product discovery, reflecting the merger of Société Générale and Crédit du Nord banks. The site exhibits professional branding, consistent messaging, and promotes official mobile applications, indicating a mature digital presence. Technically, the site uses a custom Société Générale JavaScript framework with modern asynchronous features and standard web technologies. Security measures include HTTPS and frame busting scripts, though explicit security headers could be further confirmed. The absence of WHOIS data reduces domain trust slightly but does not detract from the site's legitimacy given the strong brand presence. Privacy and cookie policies were not detected in the analyzed content, suggesting an area for improvement in compliance transparency. Overall, the site is well-structured, secure, and trustworthy for its banking audience.

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.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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: Facebook, Twitter, LinkedIn, YouTube

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

  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

Société Générale is a leading French financial institution with a significant retail banking footprint. The website targets individual customers, offering banking and insurance products. The business model focuses on comprehensive financial services, leveraging digital channels for customer engagement. The site reflects the integration of Crédit du Nord, expanding market reach. The company benefits from strong brand recognition and a broad service portfolio. Marketing and analytics tools like Tag Commander are used for customer insights and campaign tracking. The absence of direct contact details on the homepage suggests reliance on secure authenticated channels for customer support. The site’s digital maturity is moderate to high, with opportunities to enhance privacy disclosures and accessibility.

Security posture

The website demonstrates a solid security posture with HTTPS enforced and frame protection scripts in place. No sensitive data exposure or vulnerable libraries were detected in the analyzed content. Security headers are implied but not explicitly confirmed, indicating potential for improvement. The site uses standard security best practices suitable for a banking institution. No vulnerabilities or malware indicators were found. However, the lack of explicit privacy and cookie policies may pose compliance risks under GDPR. Incident response and security policy information are not publicly visible, which is common for banking sites but could be enhanced for transparency. Overall, the security maturity is good with room for enhanced header implementation and compliance documentation.

Recommendations

  1. Publish clear and accessible privacy and cookie policies to improve GDPR compliance and user trust.
  2. Explicitly implement and verify security headers such as Content-Security-Policy, X-Content-Type-Options, and Referrer-Policy.
  3. Provide visible contact information for security incidents and data protection officer to enhance transparency.
  4. Conduct regular audits of third-party scripts and tracking tools to mitigate supply chain risks.
  5. Enhance accessibility features to meet WCAG standards and improve user experience for all customers.

Technical notes

Notes

The website employs a custom JavaScript framework developed by Société Générale, incorporating asynchronous loading, event tracking, and modular script management. It uses modern JavaScript features supported by regenerator-runtime for async/await compatibility. The site is mobile-optimized with responsive design elements and includes smart banners for app promotion. Performance is moderate, with potential improvements in load times by optimizing script delivery. SEO is supported by proper meta tags and Open Graph data. No major CMS or third-party frameworks like React or Angular were detected, indicating a bespoke platform. Hosting details are not explicit but likely managed by Société Générale or a trusted provider. Overall, the technical infrastructure is robust but could benefit from modernization and enhanced accessibility.
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.
