The National Online Self Exclusion Scheme Limited · Government · United Kingdom
Low risk. 2 critical or high findings in Security headers and SSL/TLS.
GAMSTOP operates as a national self-exclusion scheme in Great Britain, providing a free service that enables individuals to restrict their online gambling activities across licensed operators. The organization is identified as The National Online Self Exclusion Scheme Limited, a registered entity in the UK. The website serves as the primary portal for registration, account management, and information dissemination, targeting individuals seeking to control gambling behavior. The service is positioned as a trusted and socially responsible initiative within the gambling regulatory framework. Technically, the website employs modern web technologies including JavaScript, Google Fonts, and Google Analytics for user experience and analytics. The site is mobile-optimized, accessible, and uses HTTPS to secure communications. While no advanced frameworks or CMS were detected, the site demonstrates good technical implementation and SEO practices. Cookie consent mechanisms and privacy policies are clearly presented, supporting GDPR compliance. From a security perspective, the site enforces HTTPS and uses CSRF tokens in scripts, but lacks explicit security headers and published security policies or incident response contacts. No vulnerabilities or exposed sensitive data were detected in the provided content. The WHOIS query on the subdomain 'www.gamstop.co.uk' failed due to domain naming rules, but this does not impact the legitimacy of the main domain 'gamstop.co.uk', which is well-established. Overall, GAMSTOP's website presents a secure, professional, and trustworthy platform for its critical social service. Strategic improvements include enhancing security headers, publishing a security policy, and adding vulnerability disclosure information to further strengthen trust and compliance.
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.

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.
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.
