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. 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. 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

LEON operates in the hospitality and retail sectors, targeting health-conscious and fast food consumers. Their business model combines restaurant dining with retail product sales, including cookbooks and gift cards. The company leverages partnerships with Amazon and PayPal for e-commerce and payment processing. The brand has a consistent and professional online presence, with strong social media engagement. Growth indicators include product diversification and digital presence expansion. The company maintains transparency in corporate social responsibility with links to Modern Slavery and Gender Pay Gap reports. Strategic observations suggest a focus on sustainability, health trends, and convenience to maintain competitive advantage.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, comprehensive security headers, and no exposed sensitive data. However, there is a lack of publicly available security policies or incident response procedures, which could be improved to enhance trust and readiness. No vulnerability disclosures or security.txt files were found, and no direct security contact emails are provided. The use of third-party scripts is standard but should be regularly audited. Compliance with GDPR is evident through privacy and cookie policies with consent mechanisms. Overall, the security posture is solid but could benefit from enhanced transparency and incident readiness documentation.

Recommendations

  1. Publish a dedicated security policy and incident response page to improve transparency and readiness.
  2. Implement a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  3. Add explicit contact information for security incidents, such as security@ or abuse@ email addresses.
  4. Adjust robots meta tags to allow SEO indexing on key pages including the homepage to improve search visibility.
  5. Regularly audit third-party scripts and dependencies to mitigate potential vulnerabilities.

Technical notes

Notes

The website uses a modern technology stack including Next.js and React, ensuring fast loading times and excellent mobile responsiveness. The CMS is Sanity, which supports structured content management. Performance is optimized with deferred and async loading of scripts, preloading fonts, and use of CDN resources. Accessibility is good with semantic HTML and ARIA roles. SEO is partially limited due to noindex meta tags on the homepage, which should be reviewed. Hosting details are not explicit but likely use modern cloud hosting suitable for Next.js applications. Overall, the technical infrastructure is robust, scalable, and aligned with current best practices.
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.
