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's business model revolves around facilitating online restaurant reservations and providing restaurant management software, targeting both consumers and businesses in the hospitality sector. The company leverages a global network with localized domains and extensive partnerships. Revenue streams likely include subscription fees from restaurants, commissions on bookings, and marketing services. The platform's competitive advantage lies in its real-time booking technology, extensive restaurant network, and integrated marketing tools. The presence of multiple international domains and localized content indicates a strong global footprint. Strategic partnerships and affiliate programs, such as app download campaigns via Adjust, support user acquisition and retention. The company maintains a consistent brand image and offers comprehensive services that cater to diverse customer segments, from casual diners to private dining clients.

Security posture

The website exhibits a mature security posture with HTTPS enforced site-wide, use of security headers including Content Security Policy with nonce, and CSRF token implementation. Cookie consent is managed via OneTrust, aligning with GDPR requirements. 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 gap in transparency and readiness communication. The site would benefit from publishing these documents to enhance trust and demonstrate proactive security management. Overall, the security measures in place mitigate common web threats effectively, supporting a secure user experience.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and controls.
  2. Implement and publicize a vulnerability disclosure program or security.txt file.
  3. Provide clear contact information for security incidents, such as a security@ or abuse@ email.
  4. Include Data Protection Officer contact details to improve GDPR transparency.
  5. Regularly review and update security headers and conduct vulnerability assessments.

Technical notes

Notes

The website is built on a modern technology stack featuring React for frontend rendering and Apollo GraphQL for data management. Integration with Google Analytics 4 and Mixpanel provides robust analytics capabilities. Hosting via Akamai CDN ensures high performance and availability. The site is mobile-optimized with responsive design and accessibility considerations. SEO is enhanced through comprehensive meta tags, Open Graph data, and JSON-LD structured data. The use of OneTrust for cookie consent demonstrates compliance with privacy regulations. Technical debt appears minimal with modular JavaScript and CSS. Opportunities exist to further modernize by expanding accessibility features and publishing technical documentation related to security and privacy. Overall, the technical infrastructure supports a scalable and user-friendly 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.
