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

3 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. 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 in the technology sector, focusing on web application deployment and hosting. Their competitive advantage lies in offering a composable web platform with flexible serverless infrastructure and a global edge network, appealing to developers and enterprises. Revenue streams likely include subscription plans and enterprise services. The company targets developers, teams, and enterprises requiring scalable and performant web hosting. Growth indicators include a large user base (7M+ developers, 35M+ projects deployed) and high uptime SLA. Partnerships with major technology frameworks and integrations with marketing and analytics tools suggest a robust ecosystem. The company maintains a strong brand presence with consistent messaging and trust signals such as customer stories and security commitments.

Security posture

Netlify exhibits a high level of security maturity with enforced HTTPS, comprehensive security headers, and secure data collection practices. The use of OneTrust for cookie consent and HubSpot for secure forms indicates attention to privacy and data protection. No vulnerabilities or exposed sensitive data were identified in the analyzed content. The presence of an abuse reporting email and a dedicated security page suggests incident response readiness. However, the absence of a publicly visible security.txt file and explicit data protection officer contact information indicates areas for improvement. Overall, the security culture appears strong, with ongoing use of best practices and compliance measures.

Recommendations

  1. Publish a security.txt file to facilitate vulnerability disclosures and improve transparency.
  2. Enhance public documentation of incident response procedures to build trust and readiness.
  3. Regularly audit and update third-party scripts and dependencies to mitigate potential vulnerabilities.
  4. Provide clear contact information for the Data Protection Officer to strengthen GDPR compliance.
  5. Continue investing in user privacy and consent management to maintain high privacy 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.
