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

Grubhub is a large, established online food ordering and delivery platform primarily serving the United States market. Founded in 2002 and now part of Just Eat Takeaway.com, it connects consumers with over 30,000 restaurants across more than 500 cities. The business model focuses on facilitating convenient food delivery and takeout services. The website content provided is an error page indicating that the service is not available in the user's country, limiting content accessibility and analysis. Technically, the website uses AngularJS and hosts static assets on Amazon S3, with images served via Cloudinary. DNS is managed by NS1, but DNSSEC is not enabled. The site lacks visible security headers and privacy or cookie policies on the analyzed page. Analytics usage is minimal, with a custom Dashi Analytics tag detected. Mobile optimization and accessibility appear basic, and SEO metadata is present but limited due to the error page content. From a security perspective, the domain is well-established and registered consistently with the business history. However, the lack of DNSSEC and security headers, as well as absence of privacy and cookie policies, represent gaps in security and compliance posture. The site enforces geographic restrictions resulting in a 503 error page for unsupported regions, which impacts content availability and user experience. Overall, the website shows a moderate business credibility score but low content quality and privacy compliance due to the blocked content and missing policies. Strategic improvements in security headers, DNSSEC, privacy disclosures, and broader content availability would enhance trust and compliance.

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. 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';…

  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

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

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

Grubhub holds a strong position in the US food delivery market as a major platform connecting consumers with local restaurants. Its business model generates revenue through commissions on orders and delivery fees. The company targets urban consumers seeking convenient food delivery and takeout options. Being part of Just Eat Takeaway.com expands its global reach and resources. The platform's extensive restaurant network and city coverage provide competitive advantages. However, geographic restrictions limit service availability internationally. The partnership ecosystem includes hosting and DNS providers but no explicit partner domains were identified in the content. Growth indicators include a large restaurant base and city presence. The website's minimal content on the analyzed page limits deeper insights into marketing or affiliate programs.

Security posture

The security maturity level appears moderate but with notable gaps. The domain is long-established and registered without privacy protection, indicating transparency. However, the absence of DNSSEC and security headers such as Content-Security-Policy or X-Frame-Options reduces defense-in-depth. No privacy or cookie policies were found, which is a compliance concern under GDPR and other regulations. Incident response and vulnerability disclosure information are not present. The site uses HTTPS (implied by the URL) but no explicit SSL configuration details were provided. The geographic blocking via a 503 error page is a form of access control but may impact user trust. Overall, the security posture would benefit from enhanced header implementation, published policies, and incident response readiness.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Publish clear privacy and cookie policies with GDPR compliance statements and consent mechanisms.
  4. Add visible contact information and incident response channels such as security@ or abuse@ emails.
  5. Improve mobile optimization and accessibility to enhance user experience and SEO.

Technical notes

Notes

The website uses AngularJS framework and hosts static assets on Amazon S3 with images served via Cloudinary. DNS is managed by NS1 but lacks DNSSEC. The HTML content is minimal and represents an error page with HTTP status 503 indicating geographic service restriction. No CMS or advanced platforms were detected. Performance is moderate given static asset hosting but limited content. SEO metadata is present but limited by error page content. Accessibility and mobile optimization are basic. No modern JavaScript frameworks beyond AngularJS were detected. No security headers or advanced security configurations were visible in the provided data. Overall, the technical infrastructure is functional but could be modernized and hardened for better security and user experience.
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.
