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

AT&T is a leading telecommunications company in the United States, offering wireless, internet, and bundled services to consumers and businesses. The website reflects a mature digital presence with a focus on customer support, product offerings like the latest iPhone models, and account management. The company maintains a strong market position as a large enterprise with consistent branding and comprehensive service information. Technically, the site uses modern web technologies including React, Adobe Target for marketing, and Dynatrace for performance monitoring, ensuring a fast and mobile-optimized user experience. Security posture is strong with HTTPS enforcement and multiple security headers, though explicit security policies and incident response contacts are not publicly detailed. Privacy compliance is well addressed with clear privacy and cookie policies and consent mechanisms. Overall, the site is professional, trustworthy, and well-maintained, though WHOIS data is unavailable likely due to privacy protections. Strategic recommendations include publishing explicit security and incident response policies and adding vulnerability disclosure information to enhance transparency and trust.

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

4 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 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 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

  3. 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.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

AT&T operates in the telecommunications sector as a large enterprise with a broad customer base in the US. Its business model centers on providing wireless phone service, internet connectivity, and bundled packages. The company leverages partnerships with major social media platforms for brand presence and marketing. Revenue streams are primarily from consumer and business subscriptions. The website's structured data and contact information indicate a well-established corporate entity with a focus on customer service and digital engagement. Growth indicators include promotion of new devices and internet plans. The partnership ecosystem includes major platforms like LinkedIn, YouTube, Facebook, and Twitter, enhancing brand reach and customer interaction.

Security posture

The website demonstrates a strong security posture with HTTPS enforced and multiple security headers such as Content-Security-Policy and Strict-Transport-Security. No vulnerabilities or exposed sensitive data were detected in the HTML content. However, the absence of a dedicated security policy page and incident response contact information is a gap in transparency and readiness communication. There is no publicly available vulnerability disclosure program or security.txt file, which could improve the company's security culture and external reporting mechanisms. Privacy policies and cookie consent mechanisms are comprehensive and GDPR compliant, indicating good data protection practices. Overall, the security maturity is high but could benefit from enhanced public security governance documentation.

Recommendations

  1. Publish a dedicated security policy page outlining security frameworks and practices.
  2. Provide clear incident response contact channels such as security@ or abuse@ emails.
  3. Implement and publicize a vulnerability disclosure program or security.txt file.
  4. Regularly audit and update third-party scripts and marketing tags to mitigate risks.
  5. Enhance transparency on certifications and compliance to build further trust.

Technical notes

Notes

The website is built with modern web technologies including React and integrates marketing and analytics tools such as Adobe Target and Google Tag Manager. Dynatrace Real User Monitoring is used for performance tracking. The site is mobile-optimized with responsive design and accessibility features. Performance is fast with proper meta tags and SEO optimizations. No CMS was explicitly detected, suggesting a custom or proprietary platform. Hosting provider details are not disclosed. The technical infrastructure supports a high-quality user experience with robust analytics and marketing integration, though continuous monitoring of third-party scripts is recommended to avoid security 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.
