Risk levelMedium

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

The website www.stepfun.com presents itself as '阶跃AI', an AI-powered personal efficiency assistant offering services such as knowledge acquisition, information querying, language learning, creative writing, and code generation. However, the domain WHOIS data is missing, indicating the domain may be unregistered or expired, which raises concerns about the legitimacy and stability of the website. The content is minimal and currently blocked based on geographic location, redirecting users to StepFunAI, which limits the ability to fully assess the business and technical infrastructure. Technically, the site uses modern frameworks like React and Next.js, but lacks visible security headers, privacy policies, or contact information, which are critical for trust and compliance. The security posture is weak due to missing HTTPS verification and absence of security best practices. Overall, the site appears to be in an early or restricted state, with significant gaps in compliance and transparency.

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

7 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 Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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

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 business targets general users seeking AI assistance for productivity and learning tasks. The key services focus on AI-driven knowledge and creative support. Market positioning and business model details are not discernible due to limited content and lack of corporate information. No partnerships or subsidiaries are identified. The absence of WHOIS data and contact details limits confidence in business credibility. The company appears to be a small technology entity focused on AI applications, but further validation is needed.

Security posture

The security maturity level is low. The site lacks visible HTTPS confirmation, security headers, and privacy or cookie policies. No incident response or vulnerability disclosure information is available. Tracking scripts are present without clear privacy compliance. The geo-block page suggests some access control but does not compensate for the lack of foundational security measures. The missing WHOIS data further complicates trust assessment. The site is vulnerable to trust and compliance issues without improvements.

Recommendations

  1. Implement and enforce HTTPS with a valid SSL certificate to secure user connections.
  2. Publish comprehensive privacy and cookie policies to comply with GDPR and other regulations.
  3. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Provide clear contact information including security and incident response contacts.
  5. Conduct regular security audits and vulnerability assessments to identify and mitigate risks.
Site observations

Automated reading of the public site. Ratings are indicative.

Generic detected. The page at /unavailable-in-region indicates content is blocked based on geographic location. The WHOIS query returned no match, suggesting the domain may not be registered or is protected. The page content is minimal and shows a redirect prompt to StepFunAI, indicating a geo-block or access restriction. These observations may be incomplete. For a fuller analysis, contact guard@offseq.com.

Technical notes

Notes

The website is built using modern JavaScript frameworks React and Next.js, indicating a contemporary technical stack. The site includes multiple asynchronously loaded JavaScript chunks and uses external scripts from static.stepfun.com and volccdn.com for tracking and analytics. Performance appears moderate with mobile optimization rated good. However, the absence of CMS identification and hosting provider details limits infrastructure insights. The site lacks visible SEO enhancements beyond basic meta tags and Open Graph data. Accessibility features are basic, and no advanced technical SEO or security configurations are evident.
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.
