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

bunny.net is a technology company specializing in providing a global edge platform that offers next-generation Content Delivery Network (CDN), edge storage, and optimization services. Established in 1999, the company positions itself as a scalable solution for accelerating web presence worldwide. The website reflects a modern technical infrastructure leveraging React and Gatsby frameworks, with a focus on performance and mobile optimization. However, the site lacks explicit privacy, cookie, and security policies, which are critical for compliance and user trust. Security posture is moderate with room for improvement, especially in enabling DNSSEC and publishing security headers. Overall, bunny.net presents a credible and professional business with a strong market presence in the technology sector but should enhance its privacy and security transparency to align with best practices.

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

4 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 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"

    • 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. 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

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

bunny.net operates in the technology sector, targeting web developers and businesses requiring CDN and edge computing services. Its business model revolves around providing scalable, high-performance content delivery and optimization solutions globally. The company benefits from a long-established domain and consistent branding. Social media presence on Facebook and Twitter supports marketing and customer engagement. The lack of detailed business contact information and compliance documentation on the website suggests potential areas for growth in transparency and customer trust. No direct partnerships or subsidiaries were identified from the provided data.

Security posture

The security maturity of bunny.net is moderate. The domain is protected against unauthorized transfers with clientTransferProhibited status but lacks DNSSEC, which could enhance DNS security. The website does not explicitly publish security headers or incident response policies, and no vulnerability disclosure or security.txt files were found. No forms or input fields were detected, reducing immediate risk from input-based vulnerabilities. The absence of privacy and cookie policies indicates compliance gaps, particularly concerning GDPR. The overall security score reflects these gaps, recommending improvements in security transparency and technical controls.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Publish comprehensive privacy and cookie policies with clear GDPR compliance statements.
  3. Implement and display security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  4. Establish and publicize an incident response and vulnerability disclosure policy, including a security.txt file.
  5. Enhance contact information availability, including dedicated security and support email addresses, to improve trust and communication.

Technical notes

Notes

The website is built using modern web technologies including React and Gatsby, supported by Tailwind CSS for styling and Font Awesome for icons. The site demonstrates good mobile optimization and fast performance characteristics. Hosting is managed by Hosting Concepts B.V. d/b/a Registrar.eu, a reputable provider. SEO is supported by well-structured meta tags and Open Graph data. No CMS was detected, indicating a custom or static site generation approach. The technical stack is modern and well-implemented, but the lack of security headers and DNSSEC indicates some technical security debt. Overall, the infrastructure supports a scalable and performant platform but should address security enhancements to mitigate risks.
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.
