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

Netlify is a leading technology platform specializing in modern web development and deployment, offering a composable web architecture that enables developers and teams to build, deploy, and scale frontend applications efficiently. The platform supports a wide range of frontend stacks and provides serverless infrastructure, edge functions, and collaborative tools to accelerate development workflows. With millions of users, Netlify holds a strong market position in the Jamstack ecosystem. The website demonstrates a mature technical infrastructure leveraging modern frameworks such as Astro and Preact, integrated with advanced analytics and marketing tools including Google Analytics, Segment, and HubSpot. The site is hosted on Netlify's own platform, ensuring optimized performance, mobile responsiveness, and accessibility. The presence of comprehensive privacy and cookie policies with consent management reflects a commitment to regulatory compliance. From a security perspective, the site enforces HTTPS, employs robust security headers, and integrates CAPTCHA mechanisms to protect user interactions. No critical vulnerabilities or exposed sensitive data were detected. However, the absence of publicly available WHOIS data suggests privacy protection, which is justified for this business type. Overall, the security posture is strong, though the site could enhance transparency by publishing incident response contacts and a security.txt file. The overall risk assessment is low, with the website exhibiting high professionalism, trustworthiness, and compliance. Strategic recommendations include maintaining up-to-date dependencies, enhancing incident response visibility, and improving data retention disclosures to further strengthen security and privacy 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 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

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 targeting developers and teams building modern web applications. Its competitive advantages include a comprehensive suite of deployment and serverless tools, a global edge network, and seamless Git integration. Revenue streams likely derive from subscription plans and enterprise offerings. The target customer segments are developers, agencies, and enterprises seeking scalable and performant web hosting solutions. Growth indicators include a large user base and partnerships with major technology providers. The company maintains a strong partnership ecosystem evident from integrations and developer resources. Operationally, Netlify emphasizes developer experience, collaboration, and scalability, positioning itself as a leader in the Jamstack and modern web deployment market.

Security posture

Netlify's security maturity is high, with enforced HTTPS, comprehensive security headers, and integration of CAPTCHA for bot mitigation. The site demonstrates adherence to privacy regulations with clear policies and consent mechanisms. No immediate vulnerabilities or misconfigurations were identified in the website content. However, the lack of publicly available incident response information and vulnerability disclosure channels represents a minor compliance gap. Data protection practices appear robust, but transparency could be improved by publishing a security.txt file and incident response contacts. The security culture is reflected in the use of modern frameworks and continuous integration/deployment practices, supporting rapid patching and updates.

Recommendations

  1. Publish a security.txt file to facilitate vulnerability disclosures.
  2. Provide clear incident response contact information on the website.
  3. Regularly audit and update third-party libraries to mitigate vulnerabilities.
  4. Enhance transparency on data retention and privacy practices.
  5. Maintain and monitor security headers and HTTPS configurations continuously.

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.
