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

WhistleOut is a well-established online platform specializing in the comparison of phone and internet plans, providing consumers in the United States with expert guides, reviews, and news to help them make informed decisions. The website is professionally designed, mobile-optimized, and rich in relevant content, positioning it as a trusted resource in the telecommunications comparison market. Technically, the site employs a modern technology stack including Google Analytics, Google Tag Manager, Crazy Egg, Mouseflow, and Microsoft Application Insights, indicating a mature digital infrastructure focused on user analytics and experience optimization. Security-wise, the site enforces HTTPS, implements multiple security headers, and uses a consent management platform for privacy compliance, though it lacks explicit public security policies or incident response information. The absence of WHOIS registration data reduces transparency but does not detract significantly from the site's legitimacy given its professional presentation and clear affiliate disclosures. Overall, WhistleOut demonstrates a strong digital presence with good security posture and privacy compliance, suitable for its consumer audience.

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

3 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 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. 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 Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1
    • 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

WhistleOut operates primarily as an affiliate marketing business within the telecommunications sector, targeting US consumers seeking to compare mobile and internet plans. Its competitive advantage lies in comprehensive, expert-driven content and a broad provider database, enabling transparent and up-to-date comparisons. Revenue is generated through referral fees from telecom providers, as disclosed on the site. The platform maintains partnerships with multiple carriers and internet providers, as evidenced by sponsored links and promoted products. Growth indicators include frequent content updates, interactive tools like plan wizards, and integration of advanced analytics. The company maintains consistent branding and trust signals such as media mentions and affiliate disclosures, reinforcing its market position as a reliable comparison service.

Security posture

The website exhibits a mature security posture with enforced HTTPS, robust security headers including Content Security Policy, and a cookie consent mechanism aligned with GDPR requirements. However, it lacks publicly available security policies, incident response procedures, and vulnerability disclosure mechanisms, which are important for transparency and user trust. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The extensive use of third-party analytics and tracking scripts is managed through consent, but the user tracking level is extensive, which may raise privacy considerations. Overall, the security maturity is good but could be improved by publishing explicit security documentation and providing clear security contact channels.

Recommendations

  1. Publish a dedicated security policy and incident response page to enhance transparency and user trust.
  2. Implement and publicize a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  3. Provide clear company contact information, including security and abuse contacts, to improve communication channels.
  4. Review and minimize third-party tracking where possible to reduce privacy risks and improve compliance.
  5. Regularly audit and update third-party scripts and dependencies to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built with modern JavaScript frameworks and leverages multiple analytics and tracking tools to monitor user behavior and optimize performance. It uses Google Tag Manager and Google Analytics for data collection, Crazy Egg and Mouseflow for heatmaps and session recordings, and Microsoft Application Insights for telemetry. The site is mobile-optimized with responsive design and includes accessibility features. Performance is moderate, with room for improvement in load times possibly due to multiple third-party scripts. No CMS or hosting provider was explicitly identified from the HTML content. The technical infrastructure supports a rich user experience with interactive elements such as plan selection wizards and dynamic content carousels. Opportunities exist to streamline scripts and enhance performance further.
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.
