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 X-Frame-Options header

      Prevents clickjacking attacks

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

  2. GDPR outside view

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

    • 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

  4. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • High

      Domain Expires Soon

      Domain expires in 27 days

      What to do: Renew domain registration before expiration

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

EE operates in the telecommunications sector as an essential enterprise entity, serving a broad UK market with mobile and broadband services. Its business model focuses on providing network access and technology deals, leveraging its market position as a top-rated UK mobile network. The company benefits from a well-established brand and digital presence, supported by official social media channels and structured data that reinforce legitimacy. Revenue streams likely include mobile subscriptions, broadband services, and device sales. The absence of privacy and security policy disclosures suggests potential compliance gaps, but the overall digital ecosystem is robust with advanced analytics and marketing tools. EE's partnership ecosystem includes major analytics and consent providers, enhancing marketing effectiveness and regulatory compliance. The company demonstrates growth indicators through modern technology adoption and extensive service offerings.

Security posture

The website exhibits a good security posture with mandatory HTTPS encryption and integration of consent management platforms, reflecting GDPR awareness. However, the lack of visible security headers, published security policies, incident response contacts, and vulnerability disclosure mechanisms indicates room for improvement in transparency and readiness. No vulnerabilities or exposed sensitive data were detected in the provided content. The use of reputable analytics and monitoring services suggests ongoing security monitoring. To elevate security maturity, EE should consider publishing a security policy, incident response procedures, and a vulnerability disclosure program to foster trust and demonstrate proactive security management. Compliance with GDPR is implied but not explicitly documented on the site.

Recommendations

  1. Publish a comprehensive privacy policy and cookie policy accessible from the homepage.
  2. Implement and disclose a formal security policy and incident response contact information.
  3. Establish a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  4. Add security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  5. Enhance transparency around data retention policies and user privacy controls.

Technical notes

Notes

EE's website is built on a modern technology stack including React with Next.js framework, Adobe Launch for tag management, Google Tag Manager, and OneTrust for consent management. The site demonstrates fast loading times, mobile optimization, and good SEO practices with proper meta tags and structured data. Hosting details are not explicitly identified but domain registration is managed by CSC Corporate Domains, Inc. The site uses multiple external scripts for analytics and marketing, which are industry standard. Accessibility features appear to be implemented adequately. Opportunities exist to improve technical security by adding missing HTTP security headers and publishing security-related documentation. Overall, the technical infrastructure supports a high-quality user experience and robust business operations.
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.
