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

9 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

Efficacity operates as an essential entity in the energy and urban sustainability sectors, leveraging partnerships with major French institutions and private companies. Its business model focuses on R&D-driven software and consulting services aimed at accelerating carbon neutrality goals for urban territories. The company benefits from strong government backing and a wide partner ecosystem, enhancing its market position. The website reflects a mature digital presence with multilingual support and comprehensive service offerings. Growth indicators include a large partner base and membership in the French Institutes of Technology association.

Security posture

The website demonstrates a good security maturity level with HTTPS enforced and domain transfer protection. However, the lack of DNSSEC and advanced security headers indicates room for enhancement. No vulnerabilities or exposed sensitive data were detected in the HTML content. The absence of a public vulnerability disclosure or incident response policy may limit transparency in security management. Privacy compliance gaps, such as missing privacy and cookie policies, could expose the organization to regulatory risks under GDPR. Overall, the security posture is adequate but would benefit from formalized policies and technical hardening.

Recommendations

  1. Implement and publish a comprehensive privacy policy and cookie consent mechanism to improve GDPR compliance.
  2. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  3. Add security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to harden the website against common attacks.
  4. Publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  5. Enhance accessibility features to improve inclusivity and compliance with accessibility standards.

Technical notes

Notes

The website is built on a modern WordPress CMS with Elementor page builder, leveraging popular plugins for SEO (All in One SEO, Yoast SEO), multilingual support (WPML), and analytics (MonsterInsights with Google Analytics). The tech stack includes jQuery and Owl Carousel for UI components. Hosting is provided by Scaleway SAS, a reputable cloud provider. Performance is moderate with good mobile optimization. SEO is well addressed with structured data (JSON-LD), Open Graph tags, and meta descriptions. Some technical debt is noted in missing DNSSEC and security headers. Overall, the infrastructure supports a professional and scalable web presence.
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.
