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

Cabinet Brun Cessac is a Paris-based law firm established in 1991 specializing in real estate, energy, urban planning, environment, and commercial leases. The firm serves a professional clientele including property developers, local authorities, and institutional clients, offering multidisciplinary legal expertise throughout project development and financing phases. The website reflects a professional and consistent brand image with clear presentation of services and team, targeting French-speaking markets with some international reach in North and West Africa. Technically, the site is built on WordPress with Elementor and Yoast SEO, providing good SEO and mobile optimization but lacking some advanced security headers and cookie consent mechanisms. Security posture is solid with HTTPS and domain transfer protection but could be improved by enabling DNSSEC and publishing security policies. Overall, the site is trustworthy and professional with room for enhanced privacy compliance and security 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

7 findings rated critical or high. Fix these first.

  1. 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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';…

  2. 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

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 firm occupies a niche in legal services for real estate and energy sectors, leveraging a multidisciplinary approach and longstanding market presence. Its business model is service-based, targeting developers, public entities, and private clients involved in complex projects. The firm’s competitive advantage lies in its combined expertise in public and private law, and its network of international partners. The website supports business credibility through detailed service descriptions and team information but lacks explicit certifications or client testimonials. Growth potential is indicated by emphasis on recruitment and international partnerships. The firm maintains a focused digital presence without aggressive marketing or tracking tools, reflecting a professional and privacy-conscious approach.

Security posture

The website employs HTTPS with a valid SSL certificate and domain transfer lock, indicating good baseline security. However, the absence of DNSSEC and security headers such as Content Security Policy, X-Frame-Options, and HSTS reduces defense-in-depth. No visible vulnerabilities or exposed sensitive data were detected. The lack of a published security policy or incident response contact limits transparency and preparedness communication. Privacy compliance is partial, with a privacy policy located on a legal mentions page but no cookie consent mechanism. Overall, the security posture is moderate but could be significantly improved by implementing recommended headers, enabling DNSSEC, and publishing comprehensive security and privacy policies.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement standard security headers including Content Security Policy, HSTS, X-Frame-Options, and X-Content-Type-Options.
  3. Add a dedicated cookie consent banner and detailed cookie policy to comply with GDPR and ePrivacy regulations.
  4. Publish a clear security policy and incident response contact information to improve transparency and trust.
  5. Regularly audit and update third-party plugins and themes to mitigate vulnerabilities and maintain performance.

Technical notes

Notes

The website is built on a modern WordPress CMS platform using Elementor page builder and Yoast SEO plugin, ensuring good SEO and responsive design. The site loads with moderate performance, likely due to caching and minification plugins. Accessibility features are basic but present. No heavy analytics or tracking scripts were detected, indicating minimal user tracking. The site uses multiple CSS and JS minified cache files hosted on its own domain. Hosting provider is not explicitly identified but domain registrar is Gandi SAS, a reputable provider. The site structure is clear with well-defined sections and semantic HTML. Technical debt appears low but security enhancements are recommended.
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.
