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 Australia holds a significant position in the hospitality industry as a digital intermediary for restaurant reservations. Its competitive advantage lies in its extensive restaurant network, user-friendly booking system, and integration of restaurant management solutions. Revenue streams likely include commissions from bookings and subscription fees for restaurant software services. The target customer segments include everyday diners, event planners, and restaurateurs seeking efficient reservation management. The company maintains a broad partnership ecosystem, linking with various restaurant venues and leveraging affiliate programs. Strategic observations highlight a focus on expanding location-based services and enhancing user engagement through personalized experiences and loyalty programs.

Security posture

The website exhibits a mature security posture with enforced HTTPS, comprehensive security headers, and secure form handling practices. No exposed sensitive data or vulnerable libraries were detected in the analyzed content. However, the absence of a publicly available security policy, incident response plan, or vulnerability disclosure program represents a compliance gap. Data protection practices appear aligned with GDPR through privacy and cookie policies, but explicit details on data retention and incident response readiness are lacking. The security culture is implied to be strong given the platform's scale and brand reputation, though transparency could be improved by publishing dedicated security resources and contacts.

Recommendations

  1. Publish a dedicated security policy and incident response information page to enhance transparency.
  2. Implement and publicize a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  3. Provide clear security contact channels such as security@ or abuse@ email addresses.
  4. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.
  5. Enhance accessibility features to improve compliance and user experience for all users.

Technical notes

Notes

The website is built on a modern technology stack featuring React and Apollo GraphQL, enabling dynamic and responsive user interfaces. Integration with analytics and marketing tools such as Mixpanel, Google Tag Manager, and Adjust supports data-driven decision-making and targeted advertising. The site demonstrates fast loading times, mobile optimization, and strong SEO practices including canonical and hreflang tags for internationalization. No CMS was explicitly detected, suggesting a custom or proprietary platform. Hosting details are not disclosed, but performance indicators suggest a reliable infrastructure. Opportunities exist to further modernize by enhancing accessibility and publishing more detailed technical documentation for transparency.
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.
