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

Open Subscription Platforms (OSP) is a small technology-focused informational website founded in 2020 that advocates for independent subscription businesses to own and control their customer and payment data. The site provides detailed comparisons of open versus closed subscription platforms, emphasizing data portability and business independence. It targets content creators and small businesses seeking subscription solutions. Technically, the site is built using the Hugo static site generator, hosted with Cloudflare DNS services, and employs modern web standards with good mobile optimization and SEO practices. Security posture is moderate; HTTPS is enforced, but no explicit security headers or policies are published. Privacy compliance is lacking due to absence of privacy and cookie policies. Overall, the site is professional and trustworthy but would benefit from enhanced compliance and security 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

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

OSP positions itself as a niche advocate and resource for open subscription platforms, differentiating from closed platforms that lock in customer data. Its business model is informational and community-driven, likely supported by partnerships or affiliate links to subscription platforms. The target audience includes independent creators and small businesses. The platform ecosystem includes major players like Substack, Ghost, and WooCommerce. The site demonstrates consistent branding and clear mission focus. Growth potential lies in expanding educational content and formalizing partnerships. The lack of direct contact emails or phone numbers suggests a lean operation focused on content delivery rather than direct sales.

Security posture

The website enforces HTTPS and avoids exposing sensitive data, which are positive security practices. However, it lacks published privacy policies, cookie consent mechanisms, security policies, and incident response contacts, which are critical for GDPR compliance and user trust. No security headers were detected in the HTML content, indicating room for improvement in defense-in-depth. The use of third-party services like Plausible Analytics and Campaign Monitor is privacy-conscious but requires clear disclosure. Overall, the security maturity is moderate but incomplete, with compliance gaps that should be addressed to reduce risk and improve user confidence.

Recommendations

  1. Publish a comprehensive privacy policy detailing data collection, usage, and user rights.
  2. Implement a cookie policy and consent mechanism to comply with GDPR and other privacy regulations.
  3. Add security headers such as Content Security Policy (CSP), Strict-Transport-Security (HSTS), and X-Frame-Options.
  4. Provide clear incident response and security contact information to enhance transparency and trust.
  5. Regularly review third-party integrations for security and privacy compliance and disclose them clearly.

Technical notes

Notes

The website uses Hugo 0.79.0, a modern static site generator, ensuring fast performance and good SEO. Hosting and DNS are managed via Cloudflare, providing reliability and potential CDN benefits. The site includes structured data (JSON-LD) and Open Graph tags for rich social media sharing. External links are primarily to reputable subscription platforms. The site uses minimal JavaScript, mainly for analytics (Plausible) and form handling (Campaign Monitor). Mobile optimization and accessibility are good, with responsive images and semantic HTML. No CMS vulnerabilities or outdated libraries were detected. Technical risks are low, but the absence of security headers and privacy compliance features represent areas for modernization.
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.
