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 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.

Breach exposure

Leaked credentials and lookalike domains from OffSeq Breach. The counts are free; the detailed lists are paid add-ons.

Dark web exposure

Add-on

Leaked records that mention sqd.ai, from OffSeq Breach.

No leaked records found

Breach holds no records for sqd.ai right now. New leaks arrive continuously, so monitoring on Breach alerts you if that changes.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

Subsquid's market positioning leverages its decentralized network model and comprehensive SDK toolkit to differentiate itself in the blockchain indexing space. The business model focuses on enabling data access at scale for AI and Web3 applications, with revenue likely generated from network participation and cloud services. The target audience includes blockchain developers and AI integrators. The company demonstrates growth potential through its ecosystem partnerships and active developer support. However, the absence of explicit business contact details and privacy policies may limit trust for some stakeholders.

Security posture

The website employs HTTPS with good SSL configuration and integrates cookie consent mechanisms, indicating a baseline security posture. However, the lack of explicit security headers such as Content-Security-Policy and absence of published security policies or incident response plans suggest room for improvement. No vulnerabilities or exposed sensitive data were detected in the HTML content. The security score is good but could be enhanced by formalizing security governance documentation and improving transparency around data protection practices.

Recommendations

  1. Publish a comprehensive privacy policy page to improve privacy compliance and user trust.
  2. Add a terms of service page to clarify user rights and obligations.
  3. Provide clear and verified contact information including support and security contacts.
  4. Implement and declare a security incident response and vulnerability disclosure policy.
  5. Enhance security headers such as Content-Security-Policy to mitigate risks.

Technical notes

Notes

The website is built on Webflow CMS with modern JavaScript libraries including Three.js for animations, ApexCharts for data visualization, and Swiper.js for UI components. Analytics are implemented via Google Tag Manager, PostHog, and Plausible, indicating a mature approach to user behavior tracking. The site is mobile optimized, fast loading, and well structured for SEO. Hosting is managed by Webflow, providing reliable infrastructure. Technical debt appears minimal, but the site could benefit from additional accessibility features and explicit security headers.
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.
