Subscribe on Android is a specialized web service operated by Blubrry Podcasting that facilitates easy podcast subscription for Android users through One Click subscribe links. The service aims to bridge the gap between Android podcast apps and the seamless subscription experience enjoyed by iOS users. The website promotes multiple Android podcast apps and provides resources for developers and podcasters to implement the subscription protocol. Technically, the site uses modern web technologies including Materialize CSS and jQuery, and integrates Google Analytics for user tracking. The site is mobile-optimized and presents a professional user experience with clear navigation and relevant content. Security-wise, the site uses HTTPS but lacks explicit security headers and a cookie consent mechanism, which are areas for improvement. The absence of WHOIS data for the domain is a concern for domain legitimacy, although the affiliation with Blubrry Podcasting provides some trust assurance. Overall, the site is functional and serves a niche audience effectively but could enhance its security posture and privacy compliance.

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
4 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 18 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
Business profile
The business operates within the media and technology sectors, focusing on podcasting services for Android users. It leverages the reputation and infrastructure of Blubrry Podcasting to provide value-added services such as One Click subscription links and developer resources. The business model is primarily service-oriented, offering free tools to increase podcast subscriptions on Android devices while promoting Blubrry's hosting and related services. The target audience includes Android podcast listeners, app developers, and podcasters. The company maintains partnerships with various podcast apps and related services, enhancing its ecosystem. Growth potential lies in expanding adoption of the One Click protocol among Android apps and podcasters. The lack of direct contact information and incomplete WHOIS data may limit trust from new users or partners.
Security posture
The website demonstrates a moderate security posture with HTTPS enabled, which is mandatory for secure communications. However, it lacks visible security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options, which are recommended to mitigate common web vulnerabilities. No security.txt or vulnerability disclosure policy is present, reducing transparency for security researchers. The absence of a cookie consent mechanism indicates partial non-compliance with privacy regulations like GDPR. No contact information for incident response or data protection officers is provided. Overall, while no critical vulnerabilities are apparent, the site would benefit from enhanced security controls and privacy compliance measures to strengthen its security maturity and user trust.
Recommendations
Implement comprehensive security headers including CSP, HSTS, and X-Frame-Options to improve protection against common web attacks.
Add a cookie consent banner or mechanism to comply with GDPR and other privacy regulations.
Publish a security.txt file and provide clear contact information for security incidents and data protection inquiries.
Enhance accessibility features to improve usability for all users, including those with disabilities.
Investigate and resolve the lack of WHOIS data to improve domain legitimacy and trustworthiness.

Technical notes
Notes
The website is built using Materialize CSS framework and jQuery library, providing a responsive and modern user interface. Google Analytics and Google Tag Manager are used for tracking user interactions. The site loads external fonts from Google Fonts and hosts images and assets on Blubrry's CDN. The HTML structure is valid and includes appropriate meta tags for SEO and social media sharing (Open Graph and Twitter Cards). Performance is moderate with no obvious blocking scripts. However, the site lacks advanced accessibility features and security headers. The absence of a detected CMS suggests a custom or static site implementation. Hosting provider details are not discernible from the content. Overall, the technical implementation is solid but could be improved with enhanced security and privacy features.
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.
