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

6 findings rated critical or high. Fix these first.

  1. GDPR outside view

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

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

  2. 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

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

  3. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  4. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

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

  • 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

Quandoo's market positioning as a global restaurant booking platform is supported by its extensive network of partner restaurants and localized country sites. The business model focuses on facilitating reservations and enhancing dining experiences through technology. Revenue streams likely include commissions from restaurants and value-added services. The company benefits from its parent company Recruit Holdings, a large conglomerate, which adds credibility and resources. The platform targets mobile and web users seeking convenient restaurant bookings, with a strong presence in Europe and Asia-Pacific. Strategic partnerships with payment processors and marketing platforms enhance operational capabilities. The company's use of structured data and multi-language support indicates a focus on SEO and international growth. Trust signals such as privacy policies, cookie consent, and social media presence reinforce its market reputation.

Security posture

The website exhibits a solid security foundation with HTTPS enforced site-wide, protecting data in transit. The use of OneTrust for cookie consent ensures compliance with privacy regulations and user control over tracking. Integration with Sentry and Datadog indicates proactive monitoring and error tracking. No visible security vulnerabilities or exposed credentials were found in the HTML content. However, the absence of explicit security headers like Content-Security-Policy or X-Frame-Options in the provided data suggests room for improvement. No public incident response or security policy pages were detected, which could enhance transparency and preparedness. Overall, the security posture is good but could benefit from more visible security best practices and disclosure.

Recommendations

  1. Publish a dedicated security policy and incident response page to improve transparency and user trust.
  2. Implement and verify security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Consider publishing a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Enhance accessibility features to improve compliance and user experience for all users.
  5. Regularly audit third-party scripts and libraries to ensure no vulnerabilities or privacy issues arise.

Technical notes

Notes

The website is built on a modern React-based frontend architecture, utilizing chunked JavaScript for performance optimization. It integrates multiple third-party services including Google Tag Manager, OneTrust for cookie management, Adyen for payment processing, and Datadog for monitoring. The site is hosted on a CDN with multiple preconnect hints to optimize resource loading. Mobile optimization is good with responsive design and viewport settings. SEO is enhanced through extensive use of JSON-LD structured data and meta tags. Performance appears moderate, with asynchronous loading of scripts and fonts. No CMS was explicitly detected, suggesting a custom or headless architecture. Technical risks are minimal but monitoring of third-party dependencies is advised to mitigate supply chain risks.
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.
