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. 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

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

  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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

  3. 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"

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

Nordnet holds a solid position in the French ISP market, offering diversified services beyond basic internet access, including mobile and TV packages and cybersecurity products. The business model leverages partnerships (e.g., with Orange network for mobile) and provides value-added services like digital press access via Cafeyn. The website content and structure reflect a customer-centric approach with eligibility testing and clear product segmentation. The absence of direct contact emails or phone numbers suggests a focus on digital self-service and support via partner sites. The company appears medium-sized with consistent branding and a professional online presence.

Security posture

The website demonstrates a good baseline security posture with HTTPS and cookie consent mechanisms in place. However, the absence of explicit security policies, incident response contacts, and vulnerability disclosure mechanisms indicates room for improvement in transparency and readiness. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. The use of third-party scripts is standard but should be regularly audited. Security headers are not explicitly detected, which could enhance protection against common web attacks. Overall, the security maturity is moderate but could be strengthened with published policies and enhanced technical controls.

Recommendations

  1. Implement and publish a dedicated security policy and incident response contact information on the website.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to improve protection.
  3. Introduce a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  4. Enhance accessibility features to meet compliance standards and improve user experience for all users.
  5. Regularly review and update third-party scripts and consent management tools to mitigate potential risks.

Technical notes

Notes

The website uses a modern JavaScript stack including jQuery and asynchronous loading of scripts for performance optimization. Google Tag Manager is used for analytics, and Didomi manages GDPR consent, indicating compliance and user privacy focus. The site is mobile-optimized with responsive images and adaptive layouts. SEO is supported by comprehensive meta tags and Open Graph data. However, no CMS or hosting provider details are explicitly detected. Performance is moderate, with room for improvement in loading speed and accessibility. The technical implementation is solid but could benefit from enhanced security headers and more explicit technical documentation.
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.
