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

Hidden Hearing UK is a well-established healthcare provider specializing in hearing tests and hearing aids across the United Kingdom. The company operates over 280 clinics and offers a range of services including free hearing tests, hearing aid sales, ear wax removal, and hearing aid maintenance. The website reflects a professional healthcare brand with consistent branding and a strong customer rating, positioning it as a trusted player in the UK hearing healthcare market. The parent company is likely Demant A/S, a known global hearing healthcare group, as indicated by asset URLs and branding. Technically, the website employs a modern technology stack including Google Tag Manager, Visual Website Optimizer, and Experian address validation services. It uses Azure CDN for hosting and demonstrates good mobile optimization, accessibility, and SEO practices. The site includes comprehensive cookie consent mechanisms and privacy compliance features, reflecting a mature digital infrastructure. From a security perspective, the site enforces HTTPS and uses cookie consent banners with granular controls. While explicit security headers were not fully visible in the provided data, the overall security posture is strong with no visible vulnerabilities or exposed sensitive data. However, the WHOIS lookup failed due to querying an invalid subdomain (www prefix), limiting domain registration data availability. Despite this, the domain appears legitimate based on website content and branding. Overall, Hidden Hearing UK presents a secure, compliant, and professionally managed online presence suitable for its healthcare service offerings. Strategic recommendations include enhancing security header implementation, publishing a formal security policy, and maintaining regular audits of third-party scripts to sustain security and compliance.

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

2 findings 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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  2. 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 Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

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

Hidden Hearing UK operates in the healthcare sector, focusing on audiology and hearing aid services. Its extensive clinic network and high customer ratings indicate a strong market position in the UK. The business model centers on retail and service provision of hearing healthcare products and tests. The company leverages partnerships with international brands such as Audika and HearingLife, expanding its reach and service offerings. Revenue streams likely include hearing aid sales, service appointments, and ancillary hearing care products. The website's integration of advanced analytics and marketing tools suggests a data-driven approach to customer engagement and growth. The presence of multiple regional domains indicates a strategic geographic segmentation. Overall, the company demonstrates operational maturity and a clear focus on customer service excellence.

Security posture

The website exhibits a mature security posture with mandatory HTTPS enforcement and a comprehensive cookie consent mechanism supporting GDPR compliance. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. The use of third-party analytics and marketing scripts is managed with opt-out options, enhancing privacy compliance. However, explicit security headers such as Content-Security-Policy and X-Frame-Options were not confirmed in the provided data and should be verified. The absence of a published security policy or incident response contact is a gap that could be addressed to improve transparency and readiness. Overall, the site balances usability and security effectively but could benefit from formalizing security documentation and enhancing header configurations.

Recommendations

  1. Implement and verify comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a clear security policy and incident response contact information on the website.
  3. Conduct regular security audits of third-party scripts and dependencies to mitigate supply chain risks.
  4. Maintain and enhance cookie consent mechanisms to ensure ongoing GDPR and privacy regulation compliance.
  5. Develop a long-term security strategy incorporating employee training and continuous monitoring to strengthen security culture.

Technical notes

Notes

The website is built on a modern technology stack with ASP.NET backend (implied), Azure CDN hosting, and uses multiple analytics and marketing tools such as Google Tag Manager, Visual Website Optimizer, and ClickDimensions. The site is mobile-optimized with good accessibility and SEO practices. Performance is moderate, with potential for improvement by optimizing third-party script loading. The use of Experian's address validation API indicates attention to data quality in forms. No CMS was explicitly detected, suggesting a custom or proprietary platform. Overall, the technical infrastructure supports a robust and scalable online presence but could benefit from performance tuning and enhanced security header implementation.
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.
