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

BT Group plc is a leading UK telecommunications company offering a wide range of services including broadband, TV packages, mobile deals, and landline services. The website targets UK families, communities, and businesses, positioning itself as a comprehensive provider of digital connectivity and entertainment solutions. The company's market position is strong, supported by consistent branding and a professional online presence. Technically, the website leverages modern web technologies such as Next.js, Adobe Experience Manager, and integrates advanced analytics and consent management tools like Adobe Analytics, Dynatrace, and OneTrust. The site is mobile-optimized, accessible, and SEO-friendly, reflecting a mature digital infrastructure. From a security perspective, the website enforces HTTPS, employs security headers, and uses reCAPTCHA v3 to protect forms. Consent management is robust, indicating compliance with GDPR. However, explicit security policies and incident response contacts are not publicly available, representing an area for improvement. Overall, the website is trustworthy, professionally maintained, and compliant with privacy regulations. The absence of WHOIS data is unusual but does not detract from the site's legitimacy given the brand recognition and content quality.

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

1 finding rated critical or high. Fix these first.

  1. 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.

      Server supports weak protocols: TLSv1.1

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

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

BT Group operates primarily in the telecommunications sector, serving a broad customer base across the UK. Its business model revolves around providing connectivity and entertainment services, including broadband, TV, mobile, and landline. The company benefits from strong brand recognition and partnerships with entities like EE and TNT Sports, enhancing its service offerings. Revenue streams likely include subscription services, device sales, and content partnerships. The website reflects a strategic focus on customer experience and digital engagement, with clear navigation and comprehensive service information. Growth indicators include integration of advanced analytics and consent tools, signaling investment in data-driven marketing and compliance. The partnership ecosystem is robust, linking to related domains that complement BT's core offerings.

Security posture

The website demonstrates a solid security posture with HTTPS enforcement, modern security headers, and anti-bot measures via reCAPTCHA v3. Consent management through OneTrust indicates adherence to privacy laws such as GDPR. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the lack of a publicly available security policy or incident response contact information limits transparency and may hinder rapid response to security incidents. The absence of a vulnerability disclosure program or security.txt file suggests opportunities to enhance security culture and stakeholder trust. Overall, the security maturity is good but could be improved by publishing more explicit security governance documentation.

Recommendations

  1. Publish a dedicated security policy page detailing security practices and frameworks.
  2. Establish and publicize an incident response contact channel, such as security@bt.com or abuse@bt.com.
  3. Implement and maintain a vulnerability disclosure program with a security.txt file.
  4. Regularly audit and update third-party scripts and libraries to mitigate vulnerabilities.
  5. Enhance transparency on data retention and processing policies to strengthen privacy compliance.

Technical notes

Notes

The website is built on a modern technology stack including React with Next.js for server-side rendering, Adobe Experience Manager as the CMS, and integrates advanced analytics and consent management tools. Performance is moderate with good mobile optimization and accessibility features. The use of multiple external scripts for analytics and consent is well managed but requires ongoing monitoring for security and privacy compliance. The site structure and metadata are well implemented, supporting SEO and user experience. Hosting details are not explicitly identified but the presence of VeriSign and Adobe services suggests enterprise-grade infrastructure. Opportunities exist to improve hosting transparency and optimize performance further.
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.
