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

Yunlogin.com is a professional technology company specializing in fingerprint browser solutions designed for cross-border e-commerce and multi-account management. The company offers a suite of services including anti-tracking browser environments, RPA automation, private deployment, and global IP proxy resources. Their market position is strong within the niche of e-commerce and social media marketing tools, supported by a substantial user base and multiple partner integrations. The website is well-structured, multilingual, and supports multiple platforms, reflecting a mature digital infrastructure. Security posture is solid with HTTPS and no obvious vulnerabilities, though improvements in security headers and privacy compliance are recommended. The absence of WHOIS data is a notable concern for domain legitimacy but is somewhat mitigated by the presence of official business registration and certifications. Overall, the site presents a trustworthy and professional front for its business operations.

NIS2 Art. 21(2)

  1. (a) Risk analysis and security policies: Not visible from outside

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

  • 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 company targets a specialized market segment focused on e-commerce sellers, social media marketers, and agencies requiring multi-account management and anti-fraud solutions. Their business model combines SaaS offerings with customizable private deployments, enabling scalability and flexibility. The presence of numerous testimonials and partner logos indicates a well-established ecosystem and strong customer trust. The company leverages advanced technologies such as browser fingerprinting and RPA to differentiate itself competitively. Growth indicators include a large number of active enterprise users and continuous product updates. Strategic partnerships with major e-commerce platforms enhance their market reach and credibility.

Security posture

The website demonstrates a good security baseline with enforced HTTPS and no exposed sensitive data. However, the lack of explicit security headers such as Content-Security-Policy and absence of published incident response or security policies indicate room for improvement. No vulnerabilities or malware were detected in the content. Privacy compliance is partial, with privacy and terms of service pages present but no cookie consent mechanism. The company should enhance transparency around security practices and incident handling to strengthen trust and compliance with regulations like GDPR and NIS2.

Recommendations

  1. Implement comprehensive HTTP security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Add a clear cookie consent banner and detailed cookie policy to improve GDPR compliance.
  3. Publish a dedicated security policy and incident response contact information to enhance transparency.
  4. Conduct regular security audits and vulnerability assessments to proactively identify and mitigate risks.
  5. Improve WHOIS data transparency or clarify domain registration details to increase trustworthiness.

Technical notes

Notes

The website uses a modern JavaScript stack with libraries such as jQuery, Swiper.js, and Quill.js for UI and content management. It integrates multiple analytics and tracking services including Google Analytics, Microsoft Clarity, CNZZ, and 360 Union. The platform supports multiple operating systems and devices, including Windows, Mac (Intel and M chips), Linux, iOS, Android, and WeChat Mini Programs, indicating a broad technical reach. Performance is moderate with good mobile optimization and SEO practices. However, the absence of detected CMS suggests a custom-built solution, which may require dedicated maintenance. The site could benefit from enhanced accessibility features and further performance optimization.
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.
