The National Archives · Government · United Kingdom
Medium risk. 3 critical or high findings in Security headers and SSL/TLS.
The National Archives is the official UK government archive and publisher for England and Wales, providing access to over 1,000 years of historical records. It serves a broad audience including researchers, educators, government officials, and the general public. The organization offers archival preservation, public access to collections, educational resources, exhibitions, and professional guidance. The website reflects a strong market position as the authoritative source for UK government records, supported by consistent branding and a professional digital presence. Technically, the website is built on WordPress with a modern SEO plugin (Yoast) and uses Google Tag Manager for analytics. The site is mobile-optimized, accessible, and well-structured, though some technologies like jQuery are outdated. Performance is moderate, and SEO practices are excellent. Privacy and cookie policies are comprehensive and GDPR compliant, with clear consent mechanisms. Security posture is good with HTTPS enforced and no visible sensitive data exposure. However, the absence of security headers and use of an older jQuery version present moderate risks. No formal security or incident response policies are published, and no vulnerability disclosure mechanism is evident. The domain WHOIS data is unavailable, likely due to .gov.uk registry privacy, but the domain and website content strongly indicate legitimacy and trustworthiness. Overall, the website is professional, secure, and compliant, with minor technical and security improvements recommended to enhance resilience and transparency.
Scanned
NIS2 Art. 21(2)
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.
3 findings rated critical or high. Fix these first.
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.
Prevents clickjacking attacks
What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"
Controls resources the browser is allowed to load
What to do: Implement a Content-Security-Policy appropriate for your application
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

Each check with its score, findings and the evidence it collected.
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.

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.
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.

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.
Automated reading of the public site. Ratings are indicative.
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.
