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

HengTian Network Technology Co.,Limited (Hong Kong) operates the website www.htstack.com, providing cloud computing and server rental services primarily targeting customers in Hong Kong, Japan, and the USA. The company emphasizes high-performance overseas servers, including cloud servers, physical servers, and DDoS-protected servers, leveraging Tier1 network providers and CN2 GIA acceleration for optimal connectivity. The business model focuses on server rental and hosting with additional services such as domain registration and agent distribution. The website content is professionally presented in Chinese, targeting business and individual customers seeking overseas hosting solutions. Technically, the website employs modern web technologies including Vue.js and Element UI frameworks, with analytics integrations from Baidu and 51.la. The infrastructure claims use of KVM+OVS virtualization and BGP multi-line networks. Performance is moderate with basic mobile optimization and accessibility features. SEO practices are good with proper meta tags and structured data. However, some security best practices such as HTTP security headers and cookie consent mechanisms are missing. Security posture is moderate; HTTPS is implied but no explicit security headers were detected. No exposed sensitive data or vulnerable libraries were found in the HTML content. Incident response contact is provided via noc@htstack.com, but no formal security policy or vulnerability disclosure is published. Privacy compliance is partial with a privacy policy present but no cookie consent mechanism. Overall, the website is professional and trustworthy in appearance but the absence of WHOIS domain registration data raises concerns about domain legitimacy and registration history. The business claims 17 years of experience, but domain WHOIS data is missing, which should be further investigated. Strategic improvements in security headers, privacy compliance, and domain registration transparency are recommended.

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

5 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 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. 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

    • 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

  3. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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 regional leader in overseas cloud and physical server hosting with a focus on Hong Kong and Asia-Pacific markets. Its competitive advantage lies in deep integration with Tier1 network providers and CN2 GIA acceleration, offering low latency and high stability. The business model is service-oriented, providing rental and hosting with customization options. Revenue streams likely include monthly server rentals, high-defense server packages, and value-added services like domain registration and reseller programs. The target customers are businesses requiring reliable overseas hosting, including e-commerce, digital marketing, and IT service providers. The partnership ecosystem includes major telecom and data center providers, enhancing service reliability. Growth indicators include new product launches and expansion plans to additional data center locations. The company maintains a professional online presence with clear service offerings and customer support channels.

Security posture

The security maturity level is moderate. The website uses HTTPS and does not expose sensitive data in its HTML. However, it lacks important HTTP security headers such as Content Security Policy, HSTS, and X-Frame-Options, which are critical for mitigating common web attacks. No formal security policy or vulnerability disclosure program is published, limiting transparency. Incident response contact is available, indicating some readiness for security events. Privacy compliance is partial, with a privacy policy present but no cookie consent mechanism, which may pose GDPR compliance risks. The use of third-party analytics and chat services introduces potential privacy and security considerations. Overall, the security culture appears basic but could be significantly improved with formal policies, enhanced technical controls, and compliance mechanisms.

Recommendations

  1. Implement comprehensive HTTP security headers including CSP, HSTS, X-Frame-Options, and X-XSS-Protection to enhance web security.
  2. Deploy a cookie consent banner and mechanism to improve privacy compliance and user transparency.
  3. Publish a detailed security policy and vulnerability disclosure program to build trust and facilitate responsible reporting.
  4. Improve mobile responsiveness and accessibility to enhance user experience across devices.
  5. Conduct regular security audits of third-party scripts and integrations to minimize vulnerabilities.

Technical notes

Notes

The website is built on a modern JavaScript stack using Vue.js and Element UI, providing a dynamic and interactive user interface. It integrates analytics from Baidu and 51.la and includes QQ chat for customer support. The infrastructure claims use of KVM+OVS virtualization and BGP multi-line networks with CN2 GIA acceleration, indicating a robust backend for hosting services. Performance is moderate with some room for improvement in mobile optimization and accessibility. The site uses canonical URLs and structured data (JSON-LD) for SEO. However, the absence of HTTP security headers and cookie consent mechanisms indicates technical debt in security and privacy compliance. The WHOIS data absence suggests potential risks in domain management or transparency. Overall, the technical implementation supports the business model but requires enhancements in security and compliance to reduce operational risks.
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.
