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

Supadu is a specialized technology company providing websites, eCommerce, and digital marketing solutions tailored for book publishers and university presses. Positioned as a market leader, Supadu offers a suite of services including customizable website themes, Smart Buy eCommerce buttons, metadata automation via their Supafolio API, and marketing tools designed to enhance discoverability and sales. The company is part of the Firebrand Group, indicating a stable corporate backing. Technically, the website is built on the Webflow platform, leveraging modern web technologies such as Google Analytics, Google Tag Manager, and Lottie animations for enhanced user experience. The site is fast, mobile-optimized, and well-structured, providing excellent content quality and navigation clarity. However, some security best practices like security headers and cookie consent mechanisms are not visibly implemented. From a security perspective, the site uses HTTPS and does not expose sensitive data in its HTML content. The absence of WHOIS data is a notable anomaly but does not detract significantly from the site's legitimacy given the professional presentation and trust signals. No critical vulnerabilities or malware indicators were found. Overall, Supadu presents a low-risk profile with strong business credibility and technical maturity. Strategic improvements in privacy compliance and security headers would further enhance their security posture and regulatory adherence.

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. 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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  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 Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

Supadu operates in the niche market of digital solutions for publishers, focusing on enhancing online presence and sales capabilities for book publishers and university presses. Their competitive advantage lies in their specialized Smart Buy buttons and metadata automation tools, which streamline eCommerce and marketing efforts. The business model is B2B SaaS and services, targeting medium to large publishing entities globally. The company demonstrates growth through a broad customer base of over 280 clients and partnerships within the publishing ecosystem. Their affiliation with the Firebrand Group provides additional market credibility and resource access. Supadu's strategic focus on integration, automation, and marketing tools positions them well for continued expansion in the publishing technology sector.

Security posture

Supadu's security posture is solid with HTTPS enforced and no visible exposure of sensitive data. The website lacks some advanced security headers which could mitigate risks such as clickjacking and cross-site scripting. There is no public vulnerability disclosure or incident response information, which could be improved to enhance transparency and readiness. Privacy compliance is partial; while a privacy policy is present and GDPR compliant, cookie consent mechanisms are missing. No signs of malware, phishing, or other security threats were detected. Overall, the security maturity is good but could benefit from formalized policies and enhanced technical controls.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  2. Add a cookie consent banner to comply fully with GDPR and other privacy regulations.
  3. Publish a vulnerability disclosure policy or security.txt file to improve transparency and incident response readiness.
  4. Provide clear incident response contact channels such as security@ or abuse@ email addresses.
  5. Consider publishing terms of service to clarify user and client obligations and rights.

Technical notes

Notes

The website is built on the Webflow CMS platform, utilizing modern front-end technologies including Lottie animations and Google services for analytics and tag management. The site is well-optimized for performance and mobile responsiveness, with clean HTML and CSS. Hosting is via Webflow's CDN, ensuring fast content delivery. The use of multiple Google Analytics and Tag Manager IDs suggests detailed tracking and marketing analytics. There is no evidence of legacy or vulnerable libraries. The site could improve by adding accessibility features and security headers. Overall, the technical infrastructure is modern, scalable, and well-maintained.
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.
