Security score

Risk levelHigh

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

ReSound Brazil, operated under the global GN Hearing A/S brand, specializes in manufacturing and retailing advanced hearing aids and wireless accessories. The website targets Brazilian consumers and hearing professionals, offering product information, support, and professional services. The company is well-established with a history dating back to 1943 and maintains a strong market position in the healthcare sector. Technically, the website employs modern web technologies including Google Tag Manager and Cookiebot for analytics and consent management, hosted likely on Microsoft Azure infrastructure. However, a critical security gap exists due to the absence of a valid SSL certificate and HTTPS support, exposing users to potential risks. Privacy and cookie policies are comprehensive and GDPR compliant, enhancing user trust. Overall, the site is professional and user-friendly but requires urgent security improvements to protect user data and maintain credibility.

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

6 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  2. 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

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

  3. 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

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 company operates in the healthcare sector focusing on hearing solutions, serving both end consumers and professionals. Its business model includes product sales, support services, and professional partnerships. The website reflects a mature brand with consistent branding and trust signals such as testimonials and awards. The parent company GN Hearing A/S is a reputable Danish firm, reinforcing legitimacy. The digital presence is supported by multiple language options and regional targeting, indicating a global strategy with localized execution. The absence of direct contact emails or phone numbers on the main page suggests a preference for contact via forms or professional channels. The company leverages social media for engagement and brand awareness.

Security posture

The current security posture is weak due to the lack of HTTPS and valid SSL certificates, which is a critical vulnerability. While some security headers like Content Security Policy and HttpOnly cookies are implemented, the absence of TLS protocols and HSTS reduces protection against common web threats. No explicit security or incident response policies are found on the site, indicating potential gaps in compliance and readiness. The use of Cookiebot and privacy policies shows awareness of privacy regulations, but technical security must be prioritized to safeguard user data and maintain trust.

Recommendations

  1. Immediately install and configure a valid SSL/TLS certificate to enable HTTPS across the entire site.
  2. Enable modern TLS protocols (TLS 1.2 or 1.3) and disable insecure protocols.
  3. Implement HTTP Strict Transport Security (HSTS) with includeSubDomains and preload directives.
  4. Add or improve security headers such as X-Content-Type-Options, X-Frame-Options, and Referrer-Policy.
  5. Publish explicit security and incident response policies to enhance transparency and compliance.
  6. Regularly audit and update third-party scripts and libraries to avoid vulnerabilities.
  7. Enhance accessibility features and mobile optimization for better user experience.
  8. Consider adding direct verified contact emails and phone numbers for improved customer support.

Notes

The website uses a modern front-end with responsive images and SVG icons, supported by Google Tag Manager and Cookiebot for analytics and consent management. The CMS appears to be Sitecore based on asset paths and URL structure. Hosting is likely on Microsoft Azure, inferred from IP address and MX records. Performance data is unavailable, but the site includes asynchronous loading of CSS and JavaScript. Accessibility is basic with some ARIA roles and skip links. SEO is supported by canonical tags and meta descriptions. However, the lack of HTTPS and TLS protocols is a major technical risk. The site could benefit from performance optimization and enhanced accessibility compliance.
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.
