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

Xfinity operates in a highly competitive telecommunications market, leveraging Comcast's extensive infrastructure and brand recognition. The business model focuses on bundled service offerings targeting residential and business customers. The website's clear navigation and comprehensive service descriptions support customer acquisition and retention. Partnerships with Comcast business services and integration of OAuth authentication indicate a robust ecosystem. The presence of promotional offers and detailed product information suggests active marketing and customer engagement strategies.

Security posture

The website employs strong security measures including HTTPS, security headers, and secure authentication flows. No vulnerabilities or exposed sensitive data were detected in the analyzed content. However, the absence of a public security policy or incident response information limits transparency. No security.txt or vulnerability disclosure program was found, which could be improved to enhance security culture and trust. Privacy compliance is well addressed with clear policies and consent mechanisms. Incident response readiness and DPO contact details are not explicitly provided.

Recommendations

  1. Publish a dedicated security policy and incident response page to improve transparency.
  2. Implement and publicize a vulnerability disclosure program or security.txt file.
  3. Provide clear contact information for the Data Protection Officer to enhance GDPR compliance.
  4. Regularly review and update third-party scripts and libraries to mitigate potential vulnerabilities.
  5. Enhance user education on privacy and security practices through accessible website content.

Technical notes

Notes

The website is built on a modern technology stack featuring React and Sitecore CMS, supported by various proprietary APIs and OAuth 2.0 for authentication. Performance is optimized with preloading of scripts and responsive design for mobile devices. SEO best practices are implemented with comprehensive meta tags and Open Graph data. Accessibility features are present but could be further enhanced. Hosting appears to be managed by Comcast's infrastructure or major CDN providers, ensuring reliability and scalability. Opportunities exist to improve technical documentation and security transparency.
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.
