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

1 finding rated critical or high. Fix these first.

  1. 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

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

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

  • Security headers: did not complete in this scan.
  • 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 holds a strong market position in the hospitality sector as a trusted online reservation service with a large user base. Its business model revolves around providing seamless booking experiences for diners and offering software solutions to restaurateurs. The company maintains a broad partnership ecosystem, including international domains and localized services. The platform supports multiple languages and regions, indicating a global operational footprint. Revenue streams likely include subscription fees from restaurants, marketing services, and possibly transaction fees. The presence of affiliate and advertising partnerships suggests diversified monetization. The company’s strategic focus on user experience, technology integration, and compliance positions it well for continued growth in the competitive online hospitality market.

Security posture

The website exhibits a mature security posture with HTTPS enforced and multiple security headers implemented, reducing risks of common web attacks. The use of CSRF tokens and absence of exposed sensitive data in the HTML indicate good security hygiene. However, the lack of a publicly available security policy or incident response contact limits transparency and may hinder rapid incident reporting. No vulnerabilities or outdated libraries were detected in the analyzed content. GDPR compliance is evident, but further enhancements such as a vulnerability disclosure program and explicit data protection officer contact would strengthen the security framework. Overall, the site is secure but could improve communication and readiness for security incidents.

Recommendations

  1. Publish a dedicated security policy page including incident response procedures and contact information.
  2. Implement and publicize a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  3. Add explicit contact details for a Data Protection Officer or privacy contact to enhance GDPR compliance.
  4. Enhance accessibility features to meet higher standards and improve user inclusivity.
  5. Regularly audit third-party scripts and dependencies to mitigate risks from external libraries.

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 analytics platforms like Mixpanel and Google Tag Manager supports data-driven marketing and user behavior analysis. The use of Google Maps APIs enhances location-based services. Performance is moderate, with preconnect and dns-prefetch hints optimizing resource loading. The site is mobile-optimized and SEO-friendly with comprehensive meta tags and structured data. No CMS was explicitly detected, suggesting a custom or proprietary platform. Hosting details are not disclosed but the infrastructure supports global content delivery. Technical risks are minimal, though ongoing maintenance of third-party integrations is recommended to avoid technical debt.
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.
