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

Netlify is a leading technology platform that enables developers and businesses to build, deploy, and manage modern web applications with ease. Their platform integrates AI tools and code deployment capabilities, offering instant deployment and a comprehensive suite of services including deploy previews, agent runners, serverless functions, storage, and an edge network. Positioned strongly in the Jamstack ecosystem, Netlify targets developers and enterprises seeking scalable and efficient web hosting solutions. Technically, Netlify employs a modern tech stack featuring Astro and Preact frameworks, alongside robust analytics and marketing integrations such as Google Analytics, Segment, Amplitude, and HubSpot. The website demonstrates excellent performance, mobile optimization, and accessibility, reflecting a mature digital infrastructure. Hosting is provided by Netlify itself, ensuring tight integration and optimized delivery. From a security perspective, the site enforces HTTPS with strong SSL configurations and implements security headers and reCAPTCHA Enterprise for bot mitigation. Privacy compliance is well addressed with clear privacy and cookie policies and consent management via OneTrust. However, explicit security policies and incident response information are not publicly available, representing an area for improvement. Overall, the website and platform present a high level of professionalism, security, and compliance, with minor gaps in transparency around security incident handling and vulnerability disclosure. The absence of public WHOIS data is consistent with privacy protection practices common in the tech industry and does not detract from the site's legitimacy.

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

5 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 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

  3. 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

  4. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • High

      Potential Subdomain Takeover

      Subdomain api.netlify.com points to unregistered service net-nf-server-api-lb-tl-cmh-prod-1233169176.us-east-2.elb.amazonaws.com

      What to do: Remove or fix CNAME record to prevent subdomain takeover

      • WSTG-CONF-10
      • NIS2 21(2)(i)
      • IR 2024/2690 12.4: Implementing Regulation (EU) 2024/2690, Annex point 12.4: Asset inventory

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

Netlify operates as a Platform as a Service (PaaS) provider specializing in modern web application deployment and hosting. Their market positioning is strong within the Jamstack and developer platform space, offering competitive advantages through AI integration and instant deployment features. Revenue streams likely include subscription plans and enterprise services. The target customer segments include individual developers, startups, and large enterprises requiring scalable web infrastructure. The company maintains a robust partnership ecosystem, including integrations with popular frameworks and developer tools. Growth indicators are positive, supported by extensive documentation, developer guides, and community engagement. Strategic observations highlight Netlify's focus on innovation, developer experience, and expanding AI capabilities within their platform.

Security posture

Netlify demonstrates a mature security posture with enforced HTTPS, comprehensive security headers, and bot mitigation via Google reCAPTCHA Enterprise. Privacy compliance is supported by detailed privacy and cookie policies and consent management mechanisms. The site avoids exposing sensitive data and employs secure forms. However, the lack of a published security policy, incident response plan, and vulnerability disclosure program limits transparency and may impact trust for security-conscious clients. No vulnerabilities or outdated libraries were detected in the analyzed content. Overall, the security maturity is high but could be enhanced by publishing formal security documentation and providing direct security contact channels.

Recommendations

  1. Publish a dedicated security policy and incident response information on the website to improve transparency.
  2. Implement and publicize a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  3. Provide direct security contact emails (e.g., security@netlify.com) for incident reporting and inquiries.
  4. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.
  5. Enhance data retention and privacy transparency by detailing retention periods and user data handling practices.

Opportunities exist to further modernize by consolidating third-party scripts and enhancing security documentation.
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.
