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

Boluoyun.com is a Chinese cloud hosting and VPS service provider specializing in Hong Kong, US, and domestic cloud servers. The company, Shanghai YunChun Network Technology Co., Ltd., founded in 2014, offers a range of cloud hosting products including VPS, cloud servers, CDN, and server rental services. The website targets general customers seeking reliable cloud hosting solutions with a focus on the Chinese and Hong Kong markets. The business positions itself as a professional and known service provider with 24/7 technical support and multiple trust indicators such as ICP licensing and customer case studies. Technically, the website uses basic HTML, CSS, and JavaScript without modern frameworks or CMS detected. The site is moderately performant but lacks advanced mobile optimization and accessibility features. SEO is basic with meta keywords and description but no structured data or Open Graph tags. The site uses Baidu Analytics for user tracking but lacks privacy and cookie policies, indicating poor privacy compliance. From a security perspective, the domain is registered with a reputable registrar and has a long registration period with clientTransferProhibited status, indicating domain security. However, the website lacks DNSSEC, HTTPS enforcement details, and security headers, which lowers its security posture. No incident response or vulnerability disclosure information is provided, and no forms are present to assess input security. Overall, the website is functional and moderately credible but requires improvements in security best practices, privacy compliance, and technical modernization to enhance trust and user experience. Strategic recommendations include enabling DNSSEC, enforcing HTTPS with HSTS, publishing privacy and cookie policies, adding security headers, and implementing vulnerability disclosure mechanisms.

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

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

Boluoyun.com operates in the cloud hosting sector, focusing on VPS and cloud servers primarily in Hong Kong, US, and China. Its business model revolves around direct sales of cloud hosting products with self-service management portals. The company leverages its ICP license and customer testimonials to build trust. Revenue streams likely come from monthly subscriptions of VPS and dedicated servers. The target customers include small to medium enterprises and individual entrepreneurs needing cloud infrastructure. The company maintains a moderate market position with a medium-sized operation founded in 2014. Partnerships with known Chinese tech and hosting communities are evident through external links. Growth indicators include a range of product offerings and 24/7 support. The company could benefit from expanding digital marketing and compliance transparency to strengthen market presence.

Security posture

The current security maturity of boluoyun.com is moderate but with notable gaps. The domain registration is stable and secure with clientTransferProhibited status, but DNSSEC is not enabled, which is a missed opportunity for DNS security. The website lacks HTTPS enforcement details and security headers such as Content Security Policy, X-Frame-Options, and X-XSS-Protection, exposing it to potential web-based attacks. No privacy or cookie policies are published, indicating compliance gaps with GDPR and other privacy regulations. Incident response and vulnerability disclosure mechanisms are absent, reducing readiness for security incidents. The use of Baidu Analytics introduces moderate user tracking without clear privacy controls. Overall, the site needs to adopt modern security best practices and compliance measures to reduce risk and improve user trust.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Implement HTTPS with HSTS to ensure secure communication and protect user data.
  3. Add essential security headers such as Content Security Policy, X-Frame-Options, and X-XSS-Protection.
  4. Publish comprehensive privacy and cookie policies to comply with GDPR and enhance transparency.
  5. Establish a vulnerability disclosure policy and incident response contact information to improve security posture and trust.

Technical notes

Notes

The website is built with basic HTML, CSS, and JavaScript without modern frameworks or CMS detected. It uses a gb2312 charset indicating legacy encoding for Simplified Chinese. The site lacks mobile optimization and accessibility features, which could impact user experience on diverse devices. SEO is basic with meta keywords and description but no structured data or Open Graph tags, limiting search engine visibility. Performance appears moderate but could be improved with modern web technologies and optimization. The hosting provider is not explicitly identified, but domain WHOIS indicates registration with Bizcn.com, Inc. The site uses Baidu Analytics for tracking but lacks advanced marketing or retargeting tools. Overall, the technical infrastructure is functional but dated, with opportunities for modernization and improved security integration.
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.
