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

YM 接码平台 Service Platform is a newly launched global SMS receiving service platform established in 2024. It offers a wide range of virtual and real phone numbers for SMS verification across multiple countries and popular applications, targeting individuals and businesses needing to bypass SMS verification without using personal phone numbers. The platform emphasizes affordability, high success rates, and API integration for rapid verification code retrieval. Technically, the website employs modern frontend technologies such as jQuery, Bootstrap, and AOS animations, hosted with Cloudflare DNS services, ensuring good performance and mobile optimization. However, the absence of DNSSEC and security headers indicates room for improvement in security hardening. The security posture is moderate with HTTPS enforced and domain transfer protection enabled. Privacy and cookie policies are missing, which impacts compliance and user trust. Contact options are limited to Telegram and a contact form, with no direct company emails or phone numbers published. Overall, the platform presents a functional and professional service with moderate trustworthiness but requires enhancements in privacy compliance and security 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

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 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

    • 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 operates in the technology sector, providing SMS receiving services globally with a focus on affordability and coverage. Its business model revolves around renting phone numbers and offering API access for automated verification code retrieval. The platform targets users needing temporary phone numbers for account registrations on social networks and other websites. Partnerships with proxy and cloud phone service providers indicate a strategic ecosystem to support its offerings. The domain is very new, consistent with a startup phase, and the website content is professionally presented in Chinese with some English elements, targeting a primarily Chinese-speaking audience. The lack of detailed company registration or legal information limits full business credibility assessment. Advertising and affiliate links suggest additional revenue streams. Growth potential exists given the global demand for such services, but trust and compliance improvements are recommended.

Security posture

The website enforces HTTPS and uses domain transfer protection, which are positive security indicators. However, the lack of DNSSEC and missing security headers such as Content Security Policy, HSTS, and X-Frame-Options reduce the overall security posture. No explicit security policies or incident response contacts are published, which is a compliance gap. The use of third-party scripts like Google Tag Manager introduces moderate tracking but no evident vulnerabilities. No exposed sensitive data or credentials were found in the HTML content. The platform should implement DNSSEC, security headers, and publish security and privacy policies to enhance trust and compliance. Incident response readiness is unclear due to missing contact channels for security issues.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and integrity.
  2. Implement standard security headers (CSP, HSTS, X-Frame-Options) to protect against common web attacks.
  3. Publish comprehensive privacy and cookie policies to comply with GDPR and other regulations.
  4. Add explicit security policy and incident response contact information to improve transparency and readiness.
  5. Regularly audit and update third-party scripts and dependencies to mitigate vulnerabilities.

Technical notes

Notes

The website uses a modern and popular frontend technology stack including jQuery, Bootstrap, AOS animations, Slick carousel, and Fancybox for UI components and effects. It is hosted behind Cloudflare DNS, which provides performance and security benefits. The site is mobile optimized with responsive design and good SEO meta tags. Performance is enhanced by use of SSD caching technology as claimed in content. However, no CMS or backend technology is explicitly detected. The site lacks DNSSEC and security headers, which are technical risks. The presence of Google Tag Manager indicates analytics integration but also requires privacy considerations. Overall, the technical implementation is solid for a small-scale service platform but can be improved in security and privacy aspects.
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.
