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

The website ip138.com is a well-established Chinese online platform providing a variety of data lookup services including IP address location, mobile phone number attribution, postal code and area code queries, and ID card verification. Founded in 2004 and operated by 厦门市漫游科技有限公司, it serves a broad general audience primarily in China. The site offers a comprehensive suite of tools and informational services, positioning itself as a trusted resource in the technology and data query sector. The business model appears to be based on free access to information, likely monetized through advertising and affiliate partnerships. Technically, the site uses standard web technologies including HTML5, CSS, and JavaScript, with integration of Baidu analytics and link submission scripts for traffic monitoring and SEO. The domain is hosted by a reputable registrar and uses HTTPS, ensuring secure communications. The site is mobile-optimized and provides a good user experience with clear navigation and a consistent brand presence. However, there is room for improvement in accessibility and the implementation of modern security headers. From a security perspective, the site enforces HTTPS but lacks DNSSEC and explicit security headers such as Content-Security-Policy or X-Frame-Options. No privacy or cookie policies are present, which is a compliance gap especially under GDPR-like regulations. There is no visible incident response or vulnerability disclosure information. The site does not appear to be blocked by any WAF or security challenge, and no adult or questionable content is detected, making it safe for general audiences. Overall, ip138.com is a credible and functional information service platform with a solid business foundation and moderate technical maturity. Strategic improvements in privacy compliance, security headers, and transparency around security policies would enhance its trustworthiness and compliance posture.

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

9 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 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';…

  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

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

ip138.com holds a strong market position in China as a comprehensive data query platform, leveraging a broad ecosystem of related services and partner domains. Its competitive advantage lies in the diversity of its offerings, from IP and phone number lookups to financial and blockchain data tools. The business model is likely ad-supported with potential affiliate revenue streams. The target customers are general internet users seeking quick and reliable data queries. The company shows growth indicators through multiple service expansions and partnerships. The partnership ecosystem includes specialized data providers and tool developers, enhancing the platform's value proposition. Operationally, the company maintains a consistent brand and content quality, supporting sustained user engagement.

Security posture

The security posture of ip138.com is moderate. HTTPS is properly implemented, ensuring encrypted data transmission. However, the absence of DNSSEC and security headers reduces protection against DNS spoofing and clickjacking attacks. The lack of published security policies and incident response contacts indicates limited transparency and preparedness for security incidents. No vulnerabilities or exposed sensitive data were detected in the analyzed content, but the use of third-party scripts (Baidu analytics) requires ongoing monitoring. Compliance gaps exist due to missing privacy and cookie policies, which could pose regulatory risks. Overall, the site should prioritize enhancing security headers, implementing DNSSEC, and publishing clear security and privacy documentation.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Implement essential security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Publish comprehensive privacy and cookie policies with explicit user consent mechanisms.
  4. Establish and disclose a security policy and incident response contact information to improve transparency and trust.
  5. Regularly audit and update third-party scripts to mitigate potential vulnerabilities.

Technical notes

Notes

The website uses a traditional web technology stack with HTML5, CSS, and JavaScript. It integrates Baidu analytics and link submission scripts for SEO and traffic analysis. The site is mobile-optimized with responsive design CSS. Hosting is provided via a reputable registrar, DOMAIN NAME NETWORK PTY LTD. Performance is moderate with no evident critical technical debt, but accessibility features are basic and could be improved. SEO is supported by proper meta tags and canonical links. There is no detected CMS, suggesting a custom or static site architecture. The site could benefit from modern framework adoption and enhanced accessibility compliance to improve user experience and maintainability.
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.
