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

光年号 is a Chinese telecommunications platform specializing in providing global cloud phone numbers via real overseas SIM cards. The platform targets cross-border e-commerce businesses, foreign trade companies, individual developers, and teams needing stable, long-term overseas phone numbers with API integration and SMS forwarding capabilities. The website is professionally designed with clear navigation and good mobile optimization, leveraging modern technologies such as Bootstrap and jQuery, and integrates Baidu Analytics and Google Tag Manager for user tracking. However, the domain WHOIS data shows inconsistencies with a future creation date, which raises some concerns about the domain's legitimacy and longevity. Security posture is moderate with HTTPS implied but lacks DNSSEC and security headers. Privacy compliance is basic with a privacy policy present but no cookie consent mechanism. Contact information is limited to an email address with no phone or physical address provided.

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

6 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 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 Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • 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

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 positions itself as a specialized provider of overseas real SIM card cloud phone numbers, emphasizing authenticity and long-term usability to avoid account bans. Its business model revolves around online sales and management of SIM cards with value-added services like SMS API and team account management. The platform serves niche markets such as cross-border e-commerce and virtual industries, supported by a network of partner domains and customer testimonials. The company appears small in size and relatively new, founded around 2025. The partnership ecosystem includes multiple related domains focused on email marketing and independent site building, indicating a broader digital services network.

Security posture

The website demonstrates a moderate security maturity level with HTTPS usage but lacks advanced DNS security (DNSSEC) and security headers, which are important for protecting against common web attacks. No explicit security policies or incident response contacts are provided, which could hinder rapid response to security incidents. The absence of cookie consent mechanisms indicates potential non-compliance with GDPR and similar privacy regulations. No vulnerabilities or exposed sensitive data were detected in the HTML content, but reliance on third-party scripts like Baidu Analytics and Google Tag Manager requires ongoing monitoring for security risks.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement standard security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web vulnerabilities.
  3. Add a cookie consent banner and improve privacy compliance to align with GDPR and other regulations.
  4. Publish clear security and incident response policies including dedicated contact channels for security issues.
  5. Provide additional verified contact information such as phone numbers and physical addresses to improve business credibility and trust.

  3. No privacy or cookie consent banners detected, potential GDPR compliance gap.
  4. No explicit security policies or incident response information found.
  5. WHOIS data shows domain created in future date, inconsistent with website content dates.
  6. No phone numbers or physical addresses explicitly provided.
  7. Contact email kefu@qianke.ltd found but domain differs from main domain.
  8. Multiple external partner domains linked in footer and partner section.
  9. Use of Baidu Analytics and Google Tag Manager for tracking.
  10. No WAF or blocking detected; full content accessible.
Technical notes

Notes

The website uses a modern front-end stack including Bootstrap for responsive design, jQuery for DOM manipulation, and Feather Icons for UI elements. It loads external scripts for analytics and tag management from Google and Baidu, indicating a dual approach to user tracking. Hosting is managed by Chengdu West Dimension Digital Technology Co., Ltd., but DNSSEC is not enabled, which is a technical gap. Performance is moderate with no major issues detected, and mobile optimization is good. The site lacks a CMS indication, suggesting a custom or static site approach. Accessibility features are basic, and SEO is supported by proper meta tags and structured content. Technical debt appears low but could be improved by adding security headers and privacy mechanisms.
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.
