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

2 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

  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

Sellfy operates in the e-commerce sector, targeting creators and online businesses seeking simplified store management without technical complexity. Its competitive advantages include a broad feature set covering multiple product types, integrated marketing tools like upselling and affiliate programs, and transparent pricing with no transaction fees on certain plans. Revenue streams likely include subscription fees and possibly transaction fees. The company maintains active social media channels and leverages third-party marketing tools to expand reach. The business model is SaaS-based, focusing on recurring revenue from subscriptions. The platform's ecosystem includes integrations with payment processors like PayPal and Stripe, though no direct partner domains were identified. Sellfy's strategic focus on ease of use and comprehensive features positions it well against competitors like Shopify and Gumroad.

Security posture

The website exhibits a mature security posture with HTTPS enforced and multiple security headers implemented, reducing common web vulnerabilities. Cookie consent is managed via Cookiebot, indicating attention to privacy compliance. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of a dedicated security policy page, incident response contacts, and vulnerability disclosure mechanisms suggests room for improvement in transparency and readiness. The lack of a security.txt file or explicit security contact emails may hinder rapid incident reporting and response. Overall, the security posture is good but could be enhanced by publishing formal security documentation and contact channels.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and controls.
  2. Provide explicit incident response contact information, such as security@ or abuse@ email addresses.
  3. Implement a vulnerability disclosure policy and publish a security.txt file to facilitate responsible reporting.
  4. Add direct company contact emails and phone numbers on the main website to improve trust and communication.
  5. Regularly review and audit third-party scripts and dependencies to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built using Webflow CMS and hosted on Webflow's platform with Cloudflare DNS services, leveraging modern web technologies including jQuery, Lottie animations, Google Tag Manager, and Cookiebot for analytics and privacy management. The site demonstrates fast loading times, excellent mobile responsiveness, and good accessibility features such as focus outlines and semantic HTML. SEO is supported through proper meta tags, Open Graph data, and structured JSON-LD schema for organization information. The technical implementation is robust with no visible errors or broken elements. Opportunities exist to enhance security transparency and incident response readiness, but the current infrastructure supports a reliable and performant 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.
