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

The British Library is the UK's national library, serving as a comprehensive repository of over 170 million items including books, newspapers, maps, sound recordings, patents, and stamps. It provides public access through reading rooms, exhibitions, events, and business support services, positioning itself as a key cultural and educational institution in the UK. The website reflects this stature with professional design, clear navigation, and extensive content tailored to researchers, students, businesses, and the general public. Technically, the website is built on modern web technologies including Next.js and React, ensuring fast performance, mobile responsiveness, and good accessibility. The use of Google Tag Manager and CookieControl indicates a mature approach to analytics and privacy compliance. The site is well-optimized for SEO and user experience. From a security perspective, the site enforces HTTPS and implements cookie consent mechanisms, but lacks explicit security headers and a published security policy page. No vulnerabilities or exposed sensitive data were detected. The WHOIS data is unavailable due to domain naming rules for UK domains, but the official nature of the British Library and consistent branding strongly support legitimacy. Overall, the British Library website demonstrates a high level of professionalism, security, and compliance, with minor recommendations to enhance security headers and transparency around vulnerability disclosures.

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.

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

The British Library operates as a large government and non-profit entity, focusing on preserving and providing access to the UK's published heritage. Its market position is unique as the national library, offering services to a broad audience including researchers, educators, businesses, and the public. Revenue streams include charitable donations, venue hire, and business support programs. The organization maintains a strong partnership ecosystem evident from related domains and social media presence. Growth indicators include ongoing digital transformation projects and public engagement through events and exhibitions. The website supports these operations with clear service offerings and contact channels.

Security posture

The British Library website exhibits a mature security posture with enforced HTTPS, cookie consent, and no visible vulnerabilities or sensitive data leaks. However, the absence of explicit security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options represents an area for improvement. The site also lacks a dedicated security policy or vulnerability disclosure page, which could enhance transparency and incident response readiness. The public disclosure of a recent cyber-attack and ongoing recovery efforts indicates an active incident response culture. Overall, the security posture is good but could be strengthened with additional controls and published policies.

Recommendations

  1. Implement and enforce security headers including CSP, HSTS, and X-Frame-Options to mitigate common web vulnerabilities.
  2. Publish a dedicated security policy page outlining security frameworks, controls, and incident response procedures.
  3. Establish and publicize a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  4. Enhance incident response contact information with dedicated security email addresses for faster communication.
  5. Continue monitoring and updating third-party libraries and scripts to prevent vulnerabilities and maintain compliance.

Technical notes

Notes

The website leverages a modern JavaScript framework (Next.js) and React for frontend rendering, enabling server-side rendering and optimized performance. Integration with Google Tag Manager facilitates analytics and marketing tracking, while CookieControl manages user consent for cookies, supporting GDPR compliance. The site uses SVG graphics for scalable visuals and is optimized for mobile devices with responsive design. Performance is fast with preloading of key assets. No CMS is explicitly detected, suggesting a custom or proprietary content management approach. Hosting details are not explicit but likely managed by a professional provider given the site's scale and security posture. Opportunities exist to improve security headers and formalize security documentation.
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.
