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

suo.im is a Chinese-based URL shortening service operated by 深圳爱瑞电子科技有限公司. The website offers free short link generation with features such as batch URL shortening and stable, fast redirection optimized for social media platforms like WeChat and Weibo. The service targets general users including marketers and social media promoters, positioning itself as a reliable and free tool in the Chinese market. The domain registration and ICP record confirm the legitimacy and stable operation of the business. Technically, the site uses common JavaScript libraries including jQuery and Baidu Analytics for tracking. The site is mobile optimized and provides a good user experience with clear navigation and professional design. However, it lacks published privacy, cookie, and terms of service policies, which impacts privacy compliance and user trust. Security posture is moderate with no visible security headers or incident response information, but no critical vulnerabilities were detected. Overall, the site is functional and trustworthy but would benefit from enhanced privacy and security documentation.

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

8 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. 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 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';…

  3. 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 company operates in the technology sector providing URL shortening services primarily to Chinese users. Its business model is freemium with optional user login for batch management and customization. The site promotes partner platforms for custom domain short links, indicating a partnership ecosystem. The company is small-sized with a clear ICP registration and stable domain ownership. The lack of direct contact information and formal policies suggests room for growth in business credibility and compliance. The service is positioned as a reliable free tool with potential for monetization through premium features or partnerships.

Security posture

The website demonstrates a basic security posture with HTTPS usage and no exposed sensitive data. However, it lacks common security headers such as Content Security Policy, HSTS, and X-Frame-Options. There is no visible incident response or vulnerability disclosure information, which limits transparency and readiness for security incidents. The use of Baidu Analytics indicates moderate user tracking without explicit cookie consent mechanisms, raising privacy compliance concerns. No critical vulnerabilities or malware indicators were found. Overall, security maturity is moderate but could be improved by implementing security best practices and publishing relevant policies.

Recommendations

  1. Publish comprehensive privacy and cookie policies to improve privacy compliance and user trust.
  2. Implement standard security headers (CSP, HSTS, X-Frame-Options) to enhance security posture.
  3. Provide clear contact information and incident response channels for security and abuse reporting.
  4. Add cookie consent mechanisms to comply with privacy regulations and inform users about tracking.
  5. Enhance accessibility features and conduct regular security audits to maintain a secure environment.

Technical notes

Notes

The website uses a standard technology stack with jQuery and related JavaScript libraries for UI and QR code generation. Baidu Analytics is integrated for user tracking. The site is mobile responsive and uses meta viewport tags appropriately. The HTML structure is valid and SEO optimized with relevant meta descriptions and keywords in Chinese. No CMS or hosting provider details are explicitly detected. Performance is moderate with no obvious issues. The site could benefit from improved accessibility and security header implementation. Overall, the technical infrastructure supports the business needs but has room for modernization and enhanced security.
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.
