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

DuoPlus PTE. LTD. operates a professional cloud phone platform specializing in anti-detection Android virtual devices designed for multi-account social media management, particularly targeting TikTok operators and e-commerce marketers globally. The company positions itself as a niche leader with innovative technology such as the world’s first Android 15 cloud phone, offering features like global GPS and SIM simulation, one-click device reskinning, and team sharing capabilities. Their business model is SaaS-based, focusing on enabling users to manage multiple social media accounts securely and efficiently from a single interface. Technically, the website employs modern web technologies including Bootstrap 5, Popper.js, Google Tag Manager, and Facebook Pixel, ensuring a responsive and accessible user experience across devices. The site is well-optimized for SEO and performance, with comprehensive privacy and cookie policies in place. However, the absence of WHOIS registration data raises concerns about domain legitimacy, despite the professional presentation and active social media presence. From a security perspective, the site enforces HTTPS and implements cookie consent mechanisms but lacks visible HTTP security headers and published security policies or incident response plans. No vulnerabilities or exposed sensitive data were detected in the HTML content. The overall security posture is good but could be improved by adding security.txt and formal incident response disclosures. Overall, DuoPlus presents a credible and professional service offering with strong technical infrastructure and marketing presence. The primary risk lies in the missing WHOIS domain registration data, which should be investigated to confirm legitimacy. Strategic recommendations include enhancing security transparency, improving domain registration visibility, and continuing to build trust through certifications and incident response readiness.

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.

Priority findings

4 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. 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.

    • High

      No SPF record found

      SPF helps prevent email spoofing

      What to do: Add SPF record: "v=spf1 include:_spf.yourmailprovider.com ~all"

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

DuoPlus targets a specialized market segment of social media marketers and TikTok operators requiring multi-account management solutions with anti-detection capabilities. Their competitive advantage lies in deploying real ARM-based Android 15 cloud phones with global GPS and SIM simulation, differentiating them from typical emulator-based solutions. Revenue streams likely include subscription fees for cloud phone usage and affiliate marketing programs. The company maintains a strong partnership ecosystem with related service providers such as AdsPower and Salesmartly, enhancing their product offering and market reach. Growth indicators include active social media engagement, multilingual site support, and customer testimonials highlighting productivity gains. Strategic observations suggest focusing on expanding global partnerships and enhancing security compliance to solidify market position.

Security posture

The website demonstrates a moderate to good security maturity level with enforced HTTPS and cookie consent mechanisms. No critical vulnerabilities or exposed sensitive data were found in the site content. However, the lack of HTTP security headers such as Content Security Policy, HSTS, and X-Frame-Options reduces the overall security robustness. There is no publicly available security policy or incident response information, which limits transparency and preparedness perception. GDPR compliance is indicated through privacy and cookie policies. The missing WHOIS registration data is a significant trust concern and could indicate domain privacy or registration issues. Overall, the security posture is adequate for the business type but requires improvements in security headers and incident response disclosures to enhance trust and compliance.

Recommendations

  1. Implement and publish HTTP security headers including Content Security Policy, HSTS, and X-Frame-Options to strengthen site security.
  2. Publish a security policy and incident response plan on the website to improve transparency and preparedness.
  3. Add a security.txt file to facilitate vulnerability disclosure and improve security communication.
  4. Investigate and resolve the missing WHOIS registration data to enhance domain legitimacy and trustworthiness.
  5. Continue to build trust through obtaining relevant certifications and displaying them prominently on the site.

Technical notes

Notes

The website is built using modern web technologies such as Bootstrap 5 and Popper.js, ensuring responsive design and good user experience across devices. Integration with Google Tag Manager and Facebook Pixel enables effective analytics and marketing tracking. The site uses multiple external resources hosted on reputable CDNs, contributing to performance and reliability. Cookie consent and privacy policies are implemented with clear user interaction. No CMS was detected, suggesting a custom or static site architecture. Performance is moderate with room for optimization. Accessibility features are present, and SEO practices are good with proper meta tags and Open Graph data. Technical risks include lack of security headers and potential domain registration issues that could impact business continuity and trust.
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.
