Risk levelMedium

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

The website '黑洞加速-黑洞加速度器永久免费-黑洞vp(永久免费)加速器下载' offers free VPN and acceleration software primarily targeting Chinese-speaking users. It provides downloadable acceleration tools and recommendations but lacks formal business identity or contact information. The site appears to be a small-scale operation focused on software distribution and promotion within the technology sector. Technically, the site uses older JavaScript libraries and basic UI frameworks, with moderate performance and good mobile optimization. However, it lacks modern security headers and visible HTTPS enforcement, which impacts its security posture negatively. Privacy and cookie policies are absent, indicating low compliance maturity. No contact or incident response information is provided, reducing transparency and trust. The site links extensively to partner acceleration service domains, suggesting a networked ecosystem. Overall, the site is safe for general audiences with no adult content detected.

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

8 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

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 website operates in the technology sector, focusing on VPN and network acceleration software distribution. Its business model revolves around free software downloads and recommendations, targeting general users seeking improved network performance. The lack of clear business information, contact details, and compliance documentation suggests a low level of formalization and trustworthiness. The extensive network of partner domains indicates a collaborative ecosystem within the acceleration service niche. Revenue streams and growth indicators are not evident from the content. The site’s competitive advantage may lie in offering free acceleration tools, but the absence of professional trust signals limits its market position.

Security posture

The website demonstrates a low security maturity level. There is no evidence of HTTPS enforcement or security headers such as Content-Security-Policy or X-Frame-Options. No privacy or cookie policies are published, and no incident response or security contact information is available. The use of outdated JavaScript libraries may expose the site to vulnerabilities. No forms are present to assess input security. The site’s security score is low, and it is recommended to implement HTTPS, security headers, and publish privacy and incident response policies to improve security posture and compliance.

Recommendations

  1. Implement HTTPS with strong TLS configuration and enforce it site-wide.
  2. Add essential security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Publish comprehensive privacy and cookie policies with GDPR compliance considerations.
  4. Provide clear contact information including security and incident response contacts.
  5. Update JavaScript libraries to modern, secure versions and audit for vulnerabilities.

Technical notes

Notes

The website uses a basic technology stack including jQuery 1.11.1, unslider, and rem.js scripts. It integrates Matomo analytics and Baidu link submission scripts. The site is moderately performant with good mobile optimization but lacks advanced frameworks or CMS indications. The HTML structure is valid but basic, with no advanced accessibility features detected. SEO optimization is minimal with basic meta tags. Hosting provider and SSL configuration details are not visible from the HTML content. The site could benefit from modernization and improved technical infrastructure to enhance performance and security.
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.
