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

The website webauthn.me is a technical demonstration and educational platform focused on Web Authentication (WebAuthn) standards, enabling users to register credentials and authenticate using biometrics and hardware authenticators. It is operated by Auth0 Inc., a reputable identity management company founded in 2013 and now a subsidiary of Okta, Inc. The site targets developers and security professionals interested in modern authentication technologies and provides interactive tutorials, debugging tools, and informational content. The business model centers on promoting Auth0's identity platform through educational resources and demos. From a technical perspective, the website employs modern web technologies including HTML5, CSS3, JavaScript, Google Fonts, and integrates third-party services such as OneTrust for cookie consent and Google Tag Manager for analytics. The site is well-optimized for performance, mobile responsiveness, accessibility, and SEO. Hosting appears to be managed by Auth0 or associated CDN providers, ensuring fast and reliable delivery. Security posture is strong with HTTPS enforced, no exposed sensitive data, and secure input forms. However, explicit security headers are not detected, and no dedicated security or incident response policies are published on the site. Cookie consent mechanisms are implemented in compliance with GDPR. No vulnerabilities or suspicious content were identified. Overall, the website is trustworthy, professionally maintained, and serves as a valuable resource for WebAuthn technology. Strategic recommendations include enhancing security headers, publishing a security policy and incident response contacts, and adding a vulnerability disclosure program to further strengthen security and 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. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  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.

Technical appendix

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

Business context

Business profile

Auth0 Inc. leverages webauthn.me as a niche educational platform to showcase Web Authentication standards and promote its identity management solutions. The company holds a strong market position in the identity and access management sector, supported by its parent company Okta, Inc. The website's business model is primarily informational and promotional, targeting developers and security professionals. The partnership ecosystem includes Okta and various technology providers. Growth indicators include active GitHub engagement and integration with modern web technologies. The site reflects a focused strategy to educate and drive adoption of WebAuthn, enhancing Auth0's competitive advantage in secure authentication.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, secure handling of user inputs, and GDPR-compliant cookie consent. No critical vulnerabilities or exposed sensitive data were found. However, the absence of explicit security headers such as Content-Security-Policy and lack of published security policies or incident response contacts indicate areas for improvement. The site does not currently provide a vulnerability disclosure program or security.txt file, which could enhance transparency and incident management readiness. Overall, the security culture appears professional but could benefit from formalized documentation and additional technical controls.

Recommendations

  1. Implement and enforce security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  2. Publish a dedicated security policy page outlining security practices and compliance commitments.
  3. Establish and publicize an incident response contact channel and vulnerability disclosure program.
  4. Enhance transparency by adding a security.txt file at the root domain.
  5. Regularly audit third-party scripts and tracking tools to minimize privacy risks and improve user trust.

Technical notes

Notes

The website is built using standard modern web technologies with clean HTML5 and CSS3 markup, and JavaScript for interactivity. It uses Google Fonts for typography and integrates OneTrust for cookie consent management, ensuring GDPR compliance. Google Tag Manager is used for analytics and marketing tracking. Hosting is likely via Auth0's infrastructure or associated CDNs, providing fast load times and high availability. The site is mobile-optimized and accessible, with good SEO metadata including Open Graph and JSON-LD structured data. No CMS or heavy frameworks detected, indicating a lightweight and maintainable codebase. Opportunities exist to improve security headers and formalize security documentation to reduce technical risks.
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.
