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

Sub Club Podcast by RevenueCat is a specialized podcast platform focused on educating and informing app developers and subscription-based businesses about the nuances of building and growing app businesses. The site hosts multiple podcast episodes featuring interviews with industry experts, providing valuable insights into subscription app strategies. The business model revolves around content delivery via podcasting, targeting a niche audience of app entrepreneurs and developers. The website is professionally designed, with consistent branding and a clear focus on its target audience. Technically, the site leverages modern web technologies including Angular framework, Podcastpage.io CMS, and optimized media delivery via Gumlet and Transistor.fm. Hosting and domain registration are stable and reputable, with HTTPS enforced and no blocking mechanisms detected. However, the site lacks explicit privacy, cookie, and security policies, which are important for compliance and user trust. Security posture is generally good with no obvious vulnerabilities, but improvements can be made by enabling DNSSEC and adding security headers. Overall, the site is trustworthy, safe for general audiences, and professionally maintained, but could benefit from enhanced privacy and security disclosures.

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

9 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  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 X-Frame-Options header

      Prevents clickjacking attacks

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

    • 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';…

  3. 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

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 Sub Club Podcast positions itself as a thought leader in the subscription app business niche, leveraging expert interviews to provide actionable insights. Its partnership with RevenueCat, a known entity in app subscription management, adds credibility. The podcast format allows for scalable content delivery and audience engagement. The site integrates social media channels like Twitter and YouTube to expand reach. The business model is content-driven with potential monetization through sponsorships or partnerships. The absence of direct contact emails or phone numbers suggests a focus on digital engagement via forms and social media. The domain's long registration history supports a mature presence in the market. The use of third-party platforms like Podcastpage.io and Transistor.fm indicates reliance on specialized podcast hosting and CMS solutions, optimizing operational efficiency.

Security posture

The website enforces HTTPS, ensuring encrypted communication. DNS is managed via Google Domains name servers, but DNSSEC is not enabled, which is a recommended security enhancement. No security headers were detected in the HTML content, suggesting room for improvement in mitigating common web vulnerabilities. The site does not expose sensitive data or use vulnerable libraries based on the analysis. However, the lack of published security policies, incident response contacts, or vulnerability disclosure mechanisms indicates limited transparency in security governance. The presence of tracking scripts like 6sense implies user data collection, but no cookie consent mechanism was found, which may raise compliance concerns. Overall, the security posture is adequate but could be strengthened by implementing best practices in headers, policies, and user privacy controls.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement and publish comprehensive privacy and cookie policies with user consent mechanisms to comply with GDPR and other regulations.
  3. Add security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to improve web security.
  4. Publish an incident response policy and provide clear contact channels for security issues to build trust and readiness.
  5. Consider adding a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.

Technical notes

Notes

The website is built using Angular 20.1.0 framework and hosted on Podcastpage.io, a specialized podcast website builder platform. It uses MediaElement.js for audio playback, optimized image delivery via Gumlet, and Google Fonts for typography. The site loads multiple JavaScript chunks asynchronously, indicating modular and modern frontend architecture. DNS is managed by Google Domains with name servers pointing to Google Cloud DNS. The domain is registered with Squarespace Domains II LLC, indicating use of a reputable registrar. Performance is moderate with good mobile optimization and basic accessibility features. SEO is supported by proper meta tags, Open Graph, and JSON-LD structured data. The site lacks some advanced accessibility and privacy features but overall demonstrates a modern and maintainable technical infrastructure.
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.
