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

3 findings rated critical or high. Fix these first.

  1. 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';…

  2. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

Memberful is positioned as a leading SaaS provider in the membership and subscription software market, targeting creators and publishers seeking to build and monetize their communities. Its business model centers on subscription management and recurring revenue facilitation. The company benefits from its parent company Patreon, enhancing credibility and market reach. The platform's integration capabilities and API support enable custom development and seamless workflows. Customer testimonials and trust badges reinforce its reputation. The absence of direct contact emails or phone numbers on the site suggests a focus on digital-first support channels such as Intercom chat. The partnership ecosystem includes Stripe for payments and CookieYes for compliance, indicating strategic alliances that support operational excellence.

Security posture

Memberful demonstrates a mature security posture with HTTPS enforced site-wide, domain transfer lock, and Cloudflare bot management. Cookie consent is managed with a comprehensive and user-friendly mechanism, supporting GDPR compliance. However, the lack of DNSSEC implementation is a minor gap in DNS security. The site does not publish a security.txt file or explicit incident response contact emails, which could hinder vulnerability reporting and incident management. No exposed sensitive data or vulnerable libraries were detected in the HTML content. Overall, the security practices align well with industry standards for SaaS platforms, but improvements in transparency and DNS security are recommended.

Recommendations

  1. Enable DNSSEC to enhance DNS security and prevent spoofing.
  2. Publish a security.txt file to facilitate responsible vulnerability disclosure.
  3. Add explicit incident response contact information (e.g., security@ or abuse@ emails).
  4. Consider providing direct company contact emails or phone numbers for support and sales.
  5. Regularly review and update cookie consent and privacy policies to maintain compliance.

Technical notes

Notes

The website is built on a modern technology stack including Alpine.js for frontend interactivity, Swiper.js for carousels, and Tailwind CSS for styling. Hosting and DNS are managed via Cloudflare, providing performance and security benefits. Analytics are implemented using Google Analytics and Plausible, balancing detailed insights with privacy considerations. The site is mobile-optimized and accessible, with good SEO practices evident in meta tags and structured navigation. No common CMS was detected, indicating a custom-built platform tailored to Memberful's specific needs. Performance is fast with asynchronous loading of scripts and optimized assets. The technical infrastructure supports scalability and a high-quality user experience.
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.
