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

No critical or high findings. These medium findings are worth fixing next.

  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.

    • Medium

      Missing Permissions-Policy header

      Controls browser features and APIs

      What to do: Implement a Permissions-Policy to restrict feature access

      • OWASP Secure Headers: OWASP Secure Headers Project recommends Permissions-Policy: accelerometer=(), autoplay=(), camera=(), cross-origin-isolated=(),…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Medium

      Privacy policy may not be GDPR compliant

      Privacy policy lacks explicit GDPR compliance elements

      What to do: Update privacy policy to explicitly address GDPR requirements and user rights

  3. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Medium

      No DKIM record found

      DKIM adds cryptographic signatures to emails

      What to do: Configure DKIM with your email provider

    • Medium

      No MTA-STS Policy

      MTA-STS enforces TLS for email delivery

      What to do: Implement MTA-STS to prevent downgrade attacks

  4. 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.

    • Medium

      SSL Certificate Expires Within 90 Days

      SSL certificate expires in 41 days

      What to do: Plan SSL certificate renewal

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

OpenTable France benefits from the global brand's market leadership in online restaurant reservations, targeting consumers seeking convenient dining experiences. Its business model centers on facilitating bookings while offering restaurants software solutions for reservation management and marketing. The presence of multiple international localized domains indicates a broad partnership ecosystem and strategic global footprint. Revenue streams likely include subscription fees from restaurants and commissions on bookings. The platform's integration with major analytics and marketing tools suggests a data-driven approach to customer engagement and growth. While direct contact details are limited, the site provides extensive legal and privacy documentation, reinforcing professionalism and regulatory adherence.

Security posture

The website exhibits a solid security foundation with HTTPS encryption, Content Security Policy implementation, and CSRF token usage. Cookie consent is actively managed via OneTrust, indicating GDPR compliance efforts. However, the absence of publicly available security policies, incident response plans, or vulnerability disclosure programs represents a gap in transparency and preparedness communication. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The security score is high but could be improved by publishing explicit security governance documents and establishing clear channels for security incident reporting.

Recommendations

  1. Publish a dedicated security policy and incident response page to enhance transparency and user trust.
  2. Implement and publicize a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  3. Provide contact information for a Data Protection Officer or security team to comply with GDPR and improve accountability.
  4. Enhance website accessibility features to meet higher standards and improve inclusivity.
  5. Regularly audit third-party scripts and dependencies to mitigate supply chain risks and maintain security hygiene.

Technical notes

Notes

The website is built on a modern technology stack featuring React and Apollo GraphQL, enabling dynamic and responsive user experiences. Integration with Stripe facilitates secure payment processing, while analytics tools like Mixpanel and Google Tag Manager support data-driven marketing and performance monitoring. The site demonstrates good SEO practices with comprehensive meta tags, Open Graph data, and JSON-LD structured data for organization. Performance is moderate, with preconnect and dns-prefetch hints optimizing resource loading. Accessibility is basic but could be improved. Hosting details are not explicitly identified, but the use of CDN domains suggests a distributed content delivery approach. Overall, the technical infrastructure supports scalability and reliability for a large enterprise hospitality platform.
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.
