Risk levelMedium

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

The website 'OpenID Connect Playground' serves as a developer-focused tool designed to facilitate testing and understanding of OpenID Connect protocol calls. It provides step-by-step insights into the authentication process, targeting developers and technical audiences interested in identity management and OAuth2-based authentication flows. The site leverages external trusted libraries such as jQuery and Auth0's styleguide, indicating a modern and developer-friendly technical infrastructure. The presence of a cookie consent banner demonstrates some level of privacy compliance, although explicit privacy and terms of service policies are not found in the provided content. Security posture is moderate with HTTPS enabled but lacking visible security headers or vulnerability disclosures. The domain WHOIS data is unavailable, raising concerns about domain registration legitimacy, though the website content appears professional and consistent with its stated purpose.

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

The website operates as a niche developer tool within the technology sector, specifically focusing on identity and access management protocols. Its business model appears to be providing a free educational and testing platform for developers working with OpenID Connect. The site is likely maintained by or affiliated with Auth0, as indicated by branding and social media links, positioning it within a broader ecosystem of authentication services. The lack of explicit business registration or contact details limits the ability to assess revenue streams or partnerships fully. However, the use of Auth0 branding and external domains suggests a relationship with established identity management providers, enhancing its credibility within the developer community.

Security posture

The website demonstrates a basic to moderate security posture. HTTPS is enforced, ensuring encrypted communication. The implementation of a cookie consent mechanism aligns with privacy regulations. However, the absence of security headers such as Content Security Policy, HSTS, or X-Frame-Options reduces defense-in-depth. No vulnerability disclosure or security.txt file is present, limiting transparency for security researchers. The lack of contact information for incident response further weakens security readiness. No exposed sensitive data or vulnerable libraries were detected in the provided content. Overall, while the site is secure enough for its purpose, improvements in security best practices and compliance documentation are recommended.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, and X-Frame-Options to enhance protection against common web attacks.
  2. Publish clear and accessible privacy policy and terms of service documents to improve legal compliance and user trust.
  3. Provide explicit contact information for security incidents and consider adding a vulnerability disclosure or security.txt file.
  4. Verify and publish domain registration details to improve legitimacy and trustworthiness.
  5. Enhance accessibility features and SEO optimization to improve user experience and discoverability.

Technical notes

Notes

The website uses a combination of jQuery 2.2.4, Auth0 styleguide CSS, and Animate.css for UI/UX enhancements. It loads resources from reputable CDNs including cdn.auth0.com, cdnjs.cloudflare.com, and code.jquery.com. The cookie consent is managed via OneTrust scripts, indicating attention to privacy compliance. The site is mobile responsive with good navigation clarity and professional design. No CMS or hosting provider information was detected. Performance is moderate, with no explicit indicators of slow loading or technical debt. The technical stack is appropriate for a developer playground but could benefit from modernization and enhanced security configurations.
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.
