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

Open Subscription Platforms is a niche informational and advocacy website focused on promoting open subscription platforms that empower independent businesses to own and control their subscription and payment data. The platform provides detailed comparisons between open and closed subscription services, highlighting the importance of data portability and customer ownership. The website targets independent content creators, small businesses, and subscription entrepreneurs seeking transparency and control over their customer data. Technically, the site is built using the Hugo static site generator, hosted and registered via Cloudflare, and employs Plausible Analytics for privacy-conscious visitor tracking. The site is performant, mobile-optimized, and well-structured, though it lacks explicit privacy and cookie policies, which are important for compliance. Security posture is generally good with HTTPS enforced and secure form handling, but the absence of security headers and incident response information are areas for improvement. Overall, the website is trustworthy and professional, serving as a valuable resource for its target 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

8 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 website positions itself as an advocate for open subscription platforms, differentiating itself by focusing on data ownership and portability in the subscription economy. It leverages partnerships with well-known platforms like Substack, Ghost, and WooCommerce, providing curated information to help businesses choose subscription services that do not lock them in. The business model is informational and community-driven, supported by newsletter subscriptions. The site’s growth potential lies in expanding its advocacy and possibly offering more tools or integrations. The partnership ecosystem includes major payment processors like Stripe, enhancing credibility. The platform’s competitive advantage is its clear stance on data ownership and transparency in a market often criticized for vendor lock-in.

Security posture

The website demonstrates a moderate to good security maturity level. HTTPS is enforced, and no sensitive data is exposed in the HTML. The use of secure forms for email subscription indicates attention to data protection. However, the lack of explicit security headers such as Content-Security-Policy, X-Frame-Options, and others reduces the overall security posture. There is no visible incident response or vulnerability disclosure information, which could be a gap in readiness for security incidents. Compliance with GDPR is not clearly demonstrated due to missing privacy and cookie policies. Overall, the site is secure for its informational purpose but would benefit from enhanced security controls and compliance documentation.

Recommendations

  1. Implement and publish a comprehensive privacy policy and cookie policy with GDPR compliance details.
  2. Add explicit security headers (Content-Security-Policy, X-Frame-Options, Referrer-Policy) to enhance security posture.
  3. Provide clear terms of service and incident response contact information to improve transparency and trust.
  4. Consider adding direct contact information such as a company email address for support and security issues.
  5. Regularly review and update security practices and compliance documentation to maintain high trust and legal adherence.

Technical notes

Notes

The website is built on a modern static site generator (Hugo), which contributes to fast loading times and good performance. Hosting and DNS are managed by Cloudflare, providing robust infrastructure and security benefits. The site uses Plausible Analytics, a privacy-focused analytics tool, and integrates Campaign Monitor for email subscriptions. The HTML is well-structured with appropriate meta tags, Open Graph, and JSON-LD structured data, supporting SEO and social media sharing. Mobile optimization is good, though accessibility features are basic and could be improved. The absence of some security headers and compliance policies indicates areas for technical enhancement. Overall, the technical implementation is solid with room for modernization in security and compliance aspects.
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.
