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

Grubhub is a large, well-established online food ordering and delivery platform founded in 2002 and currently owned by Just Eat Takeaway.com. The company operates primarily in the United States, offering services that connect consumers with over 30,000 restaurants across more than 500 cities. The analyzed page is an error page indicating that Grubhub's food delivery service is not available in the visitor's country, limiting content visibility and interaction. Technically, the website uses AngularJS as its front-end framework and hosts static assets on Amazon S3 and Cloudinary, indicating a modern cloud-based infrastructure. DNS is managed by NS1, but DNSSEC is not enabled, which is a potential security improvement area. The page lacks visible security headers and privacy or cookie policies, which are critical for compliance and user trust. From a security perspective, the domain is legitimate and long-standing with no privacy protection on WHOIS, indicating transparency. However, the absence of security headers, privacy policies, and cookie consent mechanisms reduces the overall security posture and privacy compliance. No WAF or security challenge was detected, and the content is safe for general audiences with no adult or explicit material. Overall, the website's current page analyzed is limited in content due to geographic restrictions, impacting content quality and user experience scores. Strategic improvements in privacy compliance, security headers, and accessibility would enhance trust and compliance. The domain registration data supports a high legitimacy score, but the technical and content limitations reduce the overall AI score to a moderate level.

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 leading position in the US food delivery market, leveraging a large network of restaurants and a user-friendly online platform. Its business model focuses on facilitating food ordering and delivery services, generating revenue through commissions and delivery fees. The company targets general consumers seeking convenient food delivery and takeout options. Grubhub's parent company, Just Eat Takeaway.com, supports its market reach and operational scale. The platform's partnership ecosystem includes numerous restaurants but no explicit partner domains were identified in the analyzed content. Growth indicators include extensive city coverage and a large restaurant base. The company benefits from brand recognition and consistent branding across its digital assets.

Security posture

The security maturity level is moderate with a legitimate domain and no privacy protection, which supports transparency. However, the lack of DNSSEC, security headers, and publicly available security or incident response policies indicates gaps in security best practices. No vulnerabilities or exposed sensitive data were detected in the analyzed content, but the absence of privacy and cookie policies suggests compliance gaps with GDPR and other regulations. Incident response readiness cannot be assessed due to missing information. Overall, the security culture appears to require enhancement through formalized policies and technical controls.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Implement and publish comprehensive privacy and cookie policies with user consent mechanisms to ensure GDPR compliance.
  3. Add standard security headers such as Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and X-Content-Type-Options.
  4. Publish a security policy and incident response contact information to improve transparency and readiness.
  5. Enhance website accessibility and SEO optimizations to improve user experience and search engine visibility.

Technical notes

Notes

The website uses AngularJS framework and hosts static assets on Amazon S3 and Cloudinary, indicating a cloud-based infrastructure optimized for scalability. DNS is managed by NS1, a reputable DNS provider, but DNSSEC is not enabled, which is a security shortfall. The page analyzed is an error page with minimal content, limiting performance and SEO evaluation. No CMS was detected. The site shows basic mobile optimization and accessibility features. The lack of security headers and privacy policies indicates technical debt in security and compliance areas. Overall, the technical implementation is functional but could benefit from modernization and enhanced security controls.
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.
