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

Clubhouse is a social media platform specializing in group voice notes and social audio networking, operated by Alpha Exploration Co. The website presents a modern, well-branded interface targeting a general audience interested in voice communication with friends. The platform holds a notable market position as a recognized social audio app. Technically, the site employs modern web technologies including Google Analytics, Google Tag Manager, and Sentry for error monitoring, indicating a mature digital infrastructure. The site is mobile-optimized and SEO-friendly, though accessibility features are basic. Security posture is solid with HTTPS enforced and no exposed sensitive data, but lacks explicit security headers and a cookie consent mechanism, which are recommended for enhanced compliance and protection. WHOIS data is unavailable, which reduces domain trustworthiness, but the overall business credibility remains high due to consistent branding and presence of privacy and terms policies. Strategic improvements in security headers, cookie consent, and incident response disclosures would strengthen the security and compliance profile.

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

5 findings rated critical or high. Fix these first.

  1. 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 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';…

  2. GDPR outside view

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

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • 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

  3. 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.

    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

Clubhouse operates in the technology sector as a social media platform focused on voice communication. Its business model revolves around providing a social audio experience to a broad user base, leveraging mobile applications and web presence. The company, Alpha Exploration Co., maintains a strong brand identity and active social media channels. Revenue streams likely include app usage and potential partnerships or advertising. The absence of detailed WHOIS data suggests privacy protection or recent domain registration, common in tech startups. The company maintains privacy and terms policies, indicating regulatory awareness. The ecosystem includes integrations with major analytics and marketing tools, supporting growth and user engagement. No direct contact information is publicly available, which is typical for large tech platforms. Overall, Clubhouse demonstrates a competitive position in the social media market with a focus on innovative voice-based interaction.

Security posture

The website enforces HTTPS and uses Sentry for error monitoring, reflecting a proactive approach to security and stability. However, the absence of explicit security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options represents a gap in defense-in-depth strategies. No vulnerability disclosure or security.txt files were found, limiting transparency for security researchers. The lack of a cookie consent mechanism may impact GDPR compliance. No contact channels for incident response or security reporting are provided. Overall, the security posture is moderate with room for improvement in headers, compliance mechanisms, and incident response readiness. No critical vulnerabilities or exposed sensitive data were detected in the provided content.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, and X-Frame-Options to enhance protection against common web attacks.
  2. Add a cookie consent banner and detailed cookie policy to improve GDPR compliance and user transparency.
  3. Publish a security policy and provide clear incident response contact information to facilitate vulnerability reporting and improve trust.
  4. Consider adding a vulnerability disclosure program or security.txt file to encourage responsible security research.
  5. Enhance accessibility features to improve usability for all users and comply with accessibility standards.

Technical notes

Notes

The website uses a modern technology stack with JavaScript frameworks, Google Tag Manager, Google Analytics, and Sentry for monitoring. The CSS Paint API is utilized for advanced styling effects. The site is mobile-optimized and includes responsive design elements. Performance is moderate with asynchronous loading of analytics scripts. No CMS or hosting provider information is directly detectable from the HTML. The site structure is clear with proper meta tags for SEO and social media sharing. Technical debt appears low, but improvements in accessibility and security headers are recommended to reduce risks and enhance user experience.
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.
