69/100

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

OpenTable Ireland operates as a leading online restaurant reservation platform, enabling users to discover and book tables at restaurants across Ireland. The website is professionally designed, featuring comprehensive content and a strong brand presence. It targets consumers seeking convenient restaurant booking services and offers additional solutions for restaurateurs including management software and private dining options. Technically, the site leverages modern web technologies such as React and Apollo GraphQL, with integrations for payment processing via Stripe and user analytics through Mixpanel. Security measures include HTTPS enforcement, standard security headers, and cookie consent mechanisms, reflecting a mature security posture. However, the absence of WHOIS data limits full domain trust verification. Overall, the site presents a low-risk profile with strong business credibility and technical implementation.

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 Ireland holds a significant market position within the hospitality sector as a trusted restaurant reservation service. Its business model centers on connecting diners with restaurants through an online platform, generating revenue likely from restaurant partnerships and software services. The company maintains a broad partnership ecosystem and a global footprint, as indicated by multiple international domain links. The target audience includes Irish consumers and restaurateurs seeking efficient booking and management solutions. The website's content quality and branding consistency support strong customer trust and engagement. Growth indicators include active marketing and social media presence, as well as continuous feature enhancements such as private dining and event booking capabilities.

Security posture

The website demonstrates a solid security posture with HTTPS enabled and multiple security headers in place, including Strict-Transport-Security and X-Frame-Options. The presence of CSRF tokens and cookie consent mechanisms further enhance protection against common web threats. No exposed sensitive data or vulnerable libraries were detected in the analyzed content. While the Content-Security-Policy header appears partial, it is recommended to implement a comprehensive CSP to mitigate cross-site scripting risks. The site lacks explicit incident response or security policy disclosures, which could be improved to enhance transparency and readiness. Overall, the security maturity is good, supporting safe user interactions and data protection compliance.

Recommendations

  1. Implement a full and strict Content-Security-Policy header to strengthen defense against XSS attacks.
  2. Enhance accessibility features to meet higher compliance standards and improve user experience for all users.
  3. Publish explicit security policies and incident response procedures to increase transparency and user trust.
  4. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.
  5. Consider providing clear and verified contact information for support and security incident reporting.

Technical notes

Notes

The website is built on a modern technology stack including React for frontend rendering and Apollo GraphQL for data management, indicating a contemporary and scalable architecture. Payment processing is integrated via Stripe, ensuring secure transactions. The site uses OneTrust for cookie consent management, supporting GDPR compliance. Performance is moderate with preconnect and dns-prefetch optimizations for key external resources. SEO is well addressed with meta tags, Open Graph, and JSON-LD structured data. Accessibility is basic and could be improved. Hosting details are not explicitly identified from the content. Overall, the technical infrastructure supports a robust and user-friendly online booking experience with opportunities for further optimization and modernization.
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.
