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

Transistor Inc. operates a mature and well-established podcast hosting and analytics platform, founded in 2017. The company offers a subscription-based SaaS model targeting podcasters, podcast networks, and organizations seeking advanced podcast hosting features such as unlimited shows per account, private podcasting, dynamic ad insertion, and AI transcription. Their market position is strong, supported by positive customer testimonials, awards, and a professional web presence. Technically, the website uses modern JavaScript frameworks and integrates analytics and chat services, hosted likely on AWS infrastructure. However, a critical security gap exists due to the absence of a valid SSL certificate and HTTPS configuration, which undermines user trust and data security. Privacy compliance is partially met with a clear privacy policy but lacks a cookie consent mechanism despite tracking scripts. Overall, the business credibility and website quality are high, but security improvements are urgently needed.

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

  2. GDPR outside view

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

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, Twitter, LinkedIn, YouTube

      What to do: Document all third-party data sharing in your privacy policy

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

Transistor.fm is positioned as a premium podcast hosting solution with competitive advantages including unlimited podcast hosting on a single plan, advanced analytics, and private podcast capabilities. Their business model relies on tiered subscription plans with add-ons, appealing to a broad range of podcasters from individuals to enterprises. The company maintains a strong partnership and social media ecosystem, enhancing brand visibility and customer engagement. The presence of detailed pricing, testimonials, and awards indicates a mature marketing strategy. The lack of direct contact emails or phone numbers on the public site suggests a focus on digital engagement through dashboards and forms.

Security posture

The website's security posture is currently weak due to the lack of a valid SSL certificate and disabled TLS protocols, exposing users to potential data interception risks. No HTTP security headers were detected, and critical best practices such as HSTS and OCSP stapling are not implemented. While no known vulnerabilities like Heartbleed or POODLE were found, the absence of HTTPS is a critical issue that significantly lowers the security score. Incident response and security policies are not publicly disclosed, which may impact compliance and trust. The site uses secure third-party services for chat and analytics, but the overall security framework requires immediate enhancement to protect user data and maintain compliance.

Recommendations

  1. Immediately install and maintain a valid SSL/TLS certificate to enable HTTPS across the entire site.
  2. Enable modern TLS protocols (TLS 1.2 and TLS 1.3) and disable deprecated protocols.
  3. Implement HTTP security headers including HSTS with includeSubDomains and preload directives.
  4. Enable OCSP stapling and session resumption to improve security and performance.
  5. Add a cookie consent banner/mechanism to comply with GDPR and privacy best practices.
  6. Publish clear security and incident response policies accessible to users.
  7. Regularly audit third-party scripts and dependencies for vulnerabilities.
  8. Enhance transparency by providing direct contact information for support and security incidents.
  9. Continue leveraging structured data and SEO best practices to maintain strong market presence.
  10. Consider obtaining and displaying relevant security certifications to boost trust.
Technical notes

Notes

The website is built with modern front-end technologies including Alpine.js and uses various third-party services such as Google Tag Manager, Fathom Analytics, and Crisp Chat for analytics and customer support. Hosting appears to be on AWS infrastructure, indicated by DNS nameservers. The site has moderate load time and good mobile optimization with responsive design. SEO is enhanced by comprehensive meta tags and JSON-LD structured data including FAQ and Organization schemas. However, the invalid SSL certificate and lack of HTTPS significantly undermine the technical robustness. Performance is moderate with room for improvement in resource optimization and security hardening. Accessibility features are present but could be further enhanced. Overall, the technical infrastructure supports a professional and scalable podcast hosting platform but requires urgent security upgrades.
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.
