67/100

0–100, higher is better. How it is calculated

OpenTable Mexico operates as a leading online restaurant reservation platform, providing consumers in Mexico with the ability to discover and book tables at top restaurants 24/7. The website is part of the global OpenTable brand, offering services such as restaurant reservations, management software, marketing, private dining, and event booking. The platform targets Mexican diners seeking convenient and reliable restaurant booking experiences. Technically, the website employs modern web technologies including React, Apollo GraphQL, and integrates analytics tools like Mixpanel and Google Tag Manager. It demonstrates good SEO, accessibility, and mobile optimization practices. Security-wise, the site enforces HTTPS, uses standard security headers, and includes CSRF tokens, reflecting a mature security posture. However, it lacks publicly available security policies and incident response contacts, which could be improved to enhance trust. Overall, the site is professional, trustworthy, and well-positioned in the hospitality sector in Mexico.

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

3 findings 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

  2. GDPR outside view

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

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, LinkedIn, YouTube, Google APIs

      What to do: Document all third-party data sharing in your privacy policy

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 Mexico holds a strong market position as a trusted restaurant reservation service, leveraging its global brand recognition. Its business model revolves around providing an online platform for diners and restaurants, generating revenue through reservation services and restaurant management solutions. The target audience includes Mexican consumers and restaurateurs seeking efficient booking and marketing tools. The company maintains a broad partnership ecosystem with restaurants across major Mexican cities and integrates with various marketing and analytics platforms. Growth indicators include extensive location-based offerings and multilingual support. Strategic observations suggest opportunities in expanding direct contact channels and enhancing security transparency to further solidify market trust.

Security posture

The website exhibits a solid security foundation with HTTPS enforcement, comprehensive security headers, and protection against common web vulnerabilities such as CSRF. No exposed sensitive data or vulnerable libraries were detected in the analyzed content. However, the absence of a dedicated security policy page, incident response information, and vulnerability disclosure mechanisms indicates gaps in transparency and readiness. Compliance with GDPR is supported by the presence of privacy and cookie policies with consent mechanisms. The security culture appears mature but could benefit from enhanced communication of security practices and incident handling procedures to users and partners.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Provide clear incident response contact information such as security@ or abuse@ email addresses.
  3. Implement and publicly disclose a vulnerability disclosure policy or security.txt file.
  4. Enhance visibility of company contact information to improve user trust and support.
  5. Regularly review and audit third-party scripts and analytics tools for security compliance.

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 and marketing tools like Mixpanel, Google Tag Manager, and Adjust supports data-driven decision making. The site uses CSS Modules for styling and includes structured data (JSON-LD) for SEO enhancement. Performance is moderate with good mobile optimization and accessibility features. There is no detected CMS, suggesting a custom or proprietary platform. Hosting details are not explicitly disclosed. Technical risks are minimal but ongoing monitoring of third-party dependencies is advised to mitigate potential vulnerabilities.
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.
