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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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 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

  • Email security: did not complete in this scan.
  • DNS health: did not complete in this scan.
  • Network security: did not complete in this scan.
  • 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

Web3Auth operates a SaaS business model providing authentication SDKs and wallet services to Web3 developers and enterprises. Its competitive advantages include advanced cryptographic security features, ease of integration via Plug N Play SDKs, and customization options through the Core Kit. The recent acquisition by Consensys enhances its credibility and market reach. Revenue streams likely include subscription fees for SDK usage and wallet services. The company targets blockchain developers, dApp creators, and enterprises seeking secure user onboarding solutions. The website's partnership ecosystem includes Consensys and service providers like Calendly and Dover for sales and recruitment. Growth indicators include active documentation, demos, and a trust center. Strategic observations suggest continued focus on expanding wallet services and enhancing security features to maintain market leadership.

Security posture

Web3Auth exhibits a strong security posture with HTTPS enforced site-wide, comprehensive security headers, and no exposed sensitive data in the HTML content. The use of Multi-Party Computation and Account Abstraction in their product offerings indicates a high level of cryptographic security expertise. However, the absence of DNSSEC and a publicly available security.txt or explicit incident response contacts are areas for improvement. Privacy policies and cookie consent mechanisms are implemented, supporting GDPR compliance. No vulnerabilities or outdated libraries were detected in the site content. Overall, the security maturity is high, suitable for a company handling sensitive cryptographic key management and authentication services.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Publish a security.txt file to facilitate responsible vulnerability disclosure.
  3. Provide explicit incident response contact information (e.g., security@ or abuse@ emails).
  4. Consider obtaining and displaying relevant security certifications (e.g., ISO 27001) to boost trust.
  5. Regularly audit third-party scripts and dependencies to mitigate supply chain risks.

Technical notes

Notes

The website is built using Webflow CMS, leveraging modern front-end technologies such as Lottie for animations and Slick Carousel for UI components. Google Tag Manager is used for analytics and marketing integrations, and fonts are loaded from Google Fonts. Hosting is inferred to be on Amazon AWS based on DNS servers. The site demonstrates fast loading times, excellent mobile responsiveness, and good accessibility features. Meta tags and Open Graph data are well implemented for SEO and social sharing. No technical debt or deprecated technologies were observed. Opportunities exist to further enhance security by enabling DNSSEC and improving incident response transparency.
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.
