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

Supabase is a technology company providing a comprehensive Postgres development platform that enables developers and businesses to build scalable applications with integrated backend services such as authentication, realtime data, edge functions, storage, and vector embeddings. The platform is positioned as a leading open-source alternative in the backend-as-a-service market, with a strong developer focus and growing adoption by notable companies. Technically, the website is built on modern frameworks like Next.js and React, hosted with Cloudflare DNS, and demonstrates excellent performance and mobile optimization. Security posture is good with HTTPS enforced and domain protections in place, though there is room for improvement in publishing explicit security policies and enabling DNSSEC. Privacy compliance is currently weak due to the absence of visible privacy and cookie policies. Overall, the website is professional, trustworthy, and technically mature, but should enhance transparency around privacy and security to improve compliance and user trust.

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 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 Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  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 Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

Supabase operates in the technology sector, targeting developers and enterprises seeking backend infrastructure solutions. Its business model is platform-as-a-service, monetizing through project hosting and enterprise features. The company has established a strong market position with a growing ecosystem and partnerships, evidenced by its GitHub popularity and customer logos. The platform's modular services cater to a wide range of application needs, supporting rapid development and scalability. Supabase's growth is supported by a clear value proposition of simplifying backend complexity with open-source tools. Strategic observations include the need to formalize compliance documentation and incident response capabilities to support enterprise adoption.

Security posture

The security posture of Supabase's website is solid with HTTPS enabled and domain registration protections such as clientDeleteProhibited and clientTransferProhibited statuses. However, the lack of DNSSEC implementation is a minor gap. No explicit security policies, incident response contacts, or vulnerability disclosure programs are published, which limits transparency and may impact trust for security-conscious users. The site uses internal analytics scripts but does not expose sensitive data or show signs of vulnerabilities in the HTML content. To improve, Supabase should publish security and incident response policies, enable DNSSEC, and provide clear channels for reporting security issues. These steps would enhance compliance with standards like GDPR and NIS2 and strengthen overall security culture.

Recommendations

  1. Enable DNSSEC to enhance DNS security and prevent spoofing.
  2. Publish comprehensive privacy and cookie policies with explicit consent mechanisms.
  3. Develop and publish a formal security policy and incident response plan accessible on the website.
  4. Implement a vulnerability disclosure program and provide a security.txt file for responsible reporting.
  5. Add clear contact information for security incidents and data protection officer details if applicable.

Technical notes

Notes

The website leverages a modern technology stack including React and Next.js, ensuring fast performance and excellent mobile responsiveness. Hosting and DNS are managed via Cloudflare, providing robust infrastructure support. The site includes rich SVG graphics and preloads assets for performance optimization. SEO is well addressed with appropriate meta tags and Open Graph data. Accessibility features are present but could be further enhanced with explicit ARIA roles and labels. No CMS is detected, indicating a custom or static site generation approach. The technical implementation is strong with minimal technical debt visible, though adding security headers and formalizing privacy and security documentation would improve the technical maturity and compliance posture.
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.
