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

bunny.net is a technology company specializing in content delivery services, edge storage, and optimization solutions designed to accelerate web presence globally. Established in 1999, the company positions itself as a global edge platform catering primarily to web developers and businesses requiring scalable CDN and edge services. The website is built using modern technologies such as React with Gatsby and Tailwind CSS, reflecting a contemporary digital infrastructure with good performance and mobile optimization. However, the site lacks explicit privacy, cookie, and terms of service policies, which are critical for compliance and user trust. Security posture is moderate with no visible security headers or incident response information, and DNSSEC is not enabled, indicating areas for improvement. Overall, the domain registration data supports the legitimacy and maturity of the business, but enhancements in privacy and security disclosures are recommended.

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 competitive CDN and edge computing market, offering next-generation content delivery and optimization services. Its long domain age and consistent branding suggest a stable market presence. The business model focuses on technology service provision with a target audience of developers and enterprises seeking performance improvements for their web assets. The company leverages social media channels for outreach but does not publicly disclose detailed business registration or certification information on the website. There is no evidence of affiliate programs or advertising networks, indicating a direct service model. Strategic partnerships or subsidiaries are not identified in the provided data.

Security posture

The website demonstrates a basic security posture with HTTPS implied but no explicit security headers detected in the provided data. The absence of DNSSEC and security.txt files, as well as lack of incident response contacts, suggests limited transparency in security operations. No vulnerabilities or exposed sensitive data were identified in the content analyzed. The lack of privacy and cookie policies also indicates potential compliance gaps with GDPR and other privacy regulations. Overall, the security maturity appears moderate but could benefit from adopting best practices such as publishing security policies, enabling DNSSEC, and implementing comprehensive security headers.

Recommendations

  1. Implement and publicly link comprehensive privacy and cookie policies with clear GDPR compliance statements.
  2. Enable DNSSEC on the domain to enhance DNS security.
  3. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to improve protection against common web attacks.
  4. Publish an incident response policy and provide dedicated security contact channels (e.g., security@ or abuse@ emails).
  5. Conduct a security audit to identify and remediate any potential vulnerabilities and improve overall security posture.

Technical notes

Notes

The website is built on a modern React framework (Gatsby) with Tailwind CSS for styling and Font Awesome for icons, indicating a contemporary and maintainable tech stack. The site appears to be well-optimized for performance and mobile responsiveness. Hosting and domain registration are managed by reputable providers. However, the lack of CMS and limited metadata beyond basic SEO tags suggest a focused, possibly custom-built platform. No analytics or tracking scripts were explicitly detected in the provided content, which may reflect a privacy-conscious approach or incomplete data capture. Technical debt appears low, but improvements in security configurations and privacy compliance are recommended to align with industry standards.
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.
