Subscribe on Android is a specialized web service created by Blubrry Podcasting to facilitate easy podcast subscriptions on Android devices through a One Click subscribe protocol. The service targets Android podcast listeners and app developers, aiming to replicate the seamless subscription experience found on iOS. The website offers resources for developers and podcasters to implement this protocol and promotes various Android podcast apps with direct links to their Google Play Store pages. Technically, the site uses modern web technologies including Materialize CSS, jQuery, and Google Analytics, and is mobile optimized with responsive design. Security-wise, the site enforces HTTPS but lacks several important security headers and does not provide explicit security or incident response policies. Privacy compliance is partial, with a privacy policy present but no cookie consent mechanism. Overall, the site is credible due to its affiliation with Blubrry Podcasting but could improve in security and privacy transparency.

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.
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"
This scan found 21 issues across 6 checks. Monitoring re-runs those checks daily, emails you when something material changes and records each fix, so you can show progress.

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.

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.
Business context
Business profile
The website operates as a niche service within the podcasting ecosystem, enhancing Android user experience by simplifying podcast subscriptions. Its business model is primarily service-oriented, supporting Blubrry's broader podcast hosting and analytics offerings. The site leverages partnerships with multiple Android podcast apps and related services, creating an ecosystem that benefits both listeners and developers. The absence of direct contact information suggests a focus on self-service and automated interactions. The company’s market position is that of a trusted facilitator within the podcasting technology sector, with growth potential tied to Android podcast app adoption of their protocol.
Security posture
The security posture of the website is moderate. HTTPS is correctly implemented ensuring encrypted communications. However, the absence of key security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options reduces protection against common web attacks. No vulnerabilities or exposed sensitive data were detected in the HTML content. The site lacks published security policies or incident response contacts, which limits transparency and preparedness perception. Privacy compliance is incomplete due to missing cookie consent mechanisms despite the use of Google Analytics. Overall, the site demonstrates basic security hygiene but requires enhancements to meet higher security and compliance standards.
Recommendations
Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web vulnerabilities.
Add a cookie consent banner or mechanism to comply with GDPR and other privacy regulations.
Publish a dedicated security policy and incident response contact information to improve transparency and trust.
Consider creating a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
Regularly audit third-party scripts and libraries to ensure no vulnerable components are included.

Technical notes
Notes
The website is built using a modern front-end stack with Materialize CSS framework and jQuery for interactivity. It uses Google Fonts for typography and Google Analytics for visitor tracking. The site is mobile responsive and well-structured with proper meta tags for SEO and social sharing (Open Graph and Twitter Cards). Performance appears moderate with no obvious blocking scripts. The site does not use a CMS or complex backend technologies visible from the HTML. Hosting provider details are not explicit. Technical debt is low, but improvements in accessibility and security headers would enhance robustness and 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.
