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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

  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

Renderbus operates a cloud-based rendering service business model, targeting professional CG artists, studios, and educational users. Its competitive advantages include a large-scale rendering cluster with over 30,000 nodes, certifications such as ISO 27001 and TPN, and a comprehensive ecosystem including client software, cloud management systems, and community engagement platforms. The company leverages partnerships and subdomains to extend its service offerings. Revenue streams likely include pay-per-use rendering, subscription plans, and educational discounts. The platform's market presence is strong in China, with active marketing campaigns and user engagement through contests and community forums.

Security posture

The website demonstrates a solid security posture with HTTPS enforcement, multiple security headers, and certifications indicating compliance with recognized security standards. However, the absence of visible contact information for security incidents, lack of a published vulnerability disclosure policy or security.txt file, and missing explicit cookie consent mechanisms indicate areas for improvement. The WHOIS data is not publicly available, which may raise concerns about transparency but does not necessarily imply malicious intent. Overall, the platform appears secure but could enhance trust by improving transparency and compliance documentation.

Recommendations

  1. Implement and prominently display a cookie consent banner to comply with privacy regulations.
  2. Publish clear privacy policy and terms of service pages accessible from the main navigation.
  3. Provide explicit contact information for security incidents and general inquiries to improve transparency.
  4. Establish a vulnerability disclosure program and publish a security.txt file to encourage responsible reporting.
  5. Verify and update WHOIS registration details to improve domain trustworthiness and legitimacy.

Notes

Renderbus employs a modern web technology stack centered on React and Gatsby, enabling fast, responsive, and SEO-friendly web pages. The site uses SVG graphics extensively for icons and branding, and integrates multiple analytics and tracking services including Baidu Analytics, Microsoft Clarity, and 360 Analytics. The platform supports both PC and mobile devices with excellent optimization and accessibility features. No significant technical debt or performance bottlenecks were detected in the HTML content. Hosting provider details are not explicitly identified but the site uses CDN and analytics services typical of professional deployments.
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.
