69/100

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

OpenTable is a leading online restaurant reservation platform serving primarily Canadian diners through its opentable.ca domain. The website offers 24/7 restaurant booking services and provides restaurant management software solutions, private dining options, and marketing tools for restaurateurs. The platform is well-established with a strong market position and international presence, as evidenced by multiple localized versions and extensive location-based content. Technically, the site employs modern web technologies including React, Apollo GraphQL, and integrates analytics tools such as Mixpanel and Google Tag Manager. The website is mobile-optimized and SEO-friendly, providing a professional user experience. Security-wise, OpenTable enforces HTTPS, uses standard security headers, and includes CSRF tokens, indicating a mature security posture. Privacy compliance is robust with clear privacy and cookie policies and GDPR adherence. However, WHOIS data for the domain is not publicly available, likely due to privacy protection, which is justified for a commercial platform of this scale. Overall, OpenTable.ca is a trustworthy, professionally maintained website with strong business credibility and technical maturity.

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 operates in the hospitality sector, focusing on restaurant reservations and management software. Its business model revolves around facilitating diner bookings and providing SaaS solutions to restaurants. The platform targets Canadian diners and restaurateurs but maintains a global footprint with multiple international domains. Revenue streams likely include subscription fees from restaurants, booking commissions, and marketing services. The company leverages partnerships and maintains a broad ecosystem of related domains for development and press. The website's comprehensive content and strong branding reinforce its market leadership and customer trust.

Security posture

The website demonstrates a solid security posture with HTTPS enforcement, presence of key security headers, and no visible vulnerabilities or exposed sensitive data. The inclusion of CSRF tokens and cookie consent mechanisms further enhance security and privacy compliance. However, the absence of explicit security policy pages and incident response contacts suggests areas for improvement in transparency and readiness. No critical vulnerabilities or compliance gaps were detected in the analyzed content.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and compliance frameworks.
  2. Provide clear incident response contact information to improve transparency and trust.
  3. Enhance accessibility features to meet higher standards and improve user inclusivity.
  4. Regularly audit and update third-party scripts and analytics tools to mitigate potential vulnerabilities.
  5. Maintain and monitor WHOIS registration details to ensure domain legitimacy and prevent privacy-related concerns.

Technical notes

Notes

The website is built on a modern tech stack featuring React and Apollo GraphQL, enabling dynamic and responsive user interfaces. It integrates multiple third-party services for analytics, geolocation, and cookie management, indicating a mature digital infrastructure. Performance is moderate with good mobile optimization and SEO practices. The site uses modular CSS and preconnect/dns-prefetch hints to optimize resource loading. No CMS was explicitly detected, suggesting a custom or proprietary platform. Hosting details are not disclosed but the presence of CDN domains indicates use of content delivery networks for performance and reliability.
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.
