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

The website daiyy.com operates as a platform primarily focused on providing VPN acceleration and network security software downloads, targeting a general audience interested in improving their internet speed and security. The site is presented in Chinese and offers various software titles for Android and Apple platforms, emphasizing network data encryption and protection. However, the business information is minimal, with no clear company identity or contact details provided, limiting trust and credibility. Technically, the site is built on the ThinkPHP framework and utilizes common web technologies such as jQuery and Unslider for UI components. It employs Matomo for analytics, indicating some level of user tracking. The site shows moderate performance and basic mobile optimization but lacks advanced SEO and accessibility features. No explicit hosting provider or CMS beyond the framework is identified. From a security perspective, the website lacks critical security headers, does not enforce HTTPS visibly, and fails to provide privacy or cookie policies, which are essential for GDPR compliance and user trust. There is no incident response or vulnerability disclosure information, and no security certifications are presented. These gaps represent significant risks in terms of compliance and user data protection. Overall, the site scores low to moderate on content quality, technical implementation, security posture, and privacy compliance. The absence of contact information and trust indicators further reduces its business credibility. Strategic improvements in security, transparency, and compliance are recommended to enhance user trust and regulatory adherence.

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. 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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  3. 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';…

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, specifically focusing on VPN and network acceleration software distribution. Its business model appears to be centered on providing free or promotional downloads of VPN-related applications, targeting users seeking enhanced network security and speed. The site links to numerous related domains, suggesting a partnership ecosystem within the VPN acceleration niche. However, the lack of clear company information, contact details, and certifications indicates a small-scale operation with limited market positioning and professional branding. Revenue streams are not explicit but may include affiliate marketing or software promotion. Growth indicators and strategic partnerships are not clearly documented.

Security posture

The current security posture of the website is weak. The absence of HTTPS enforcement and security headers exposes users to potential risks such as man-in-the-middle attacks and clickjacking. The lack of privacy and cookie policies indicates non-compliance with GDPR and other data protection regulations. No incident response or vulnerability disclosure mechanisms are in place, which could delay mitigation of security incidents. The use of outdated libraries like jQuery 1.11.1 may introduce vulnerabilities. Overall, the site demonstrates minimal security best practices, increasing the risk of data breaches and regulatory penalties.

Recommendations

  1. Implement HTTPS with HSTS to secure all communications.
  2. Add essential security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Publish comprehensive privacy and cookie policies aligned with GDPR requirements.
  4. Provide clear contact information including security incident response channels.
  5. Conduct a security audit to update libraries and fix potential vulnerabilities.

Technical notes

Notes

The website is built on the ThinkPHP framework with a custom CMS, using jQuery 1.11.1 and Unslider for front-end interactions. It integrates Matomo analytics for user tracking. The site shows moderate loading performance and basic mobile responsiveness. SEO optimization is minimal with basic meta tags but no advanced structured data or Open Graph tags. Accessibility features are limited. The hosting provider is not identified, and no CDN usage is evident. The technical stack is somewhat outdated, particularly the jQuery version, which may pose security risks. Modernization opportunities include upgrading libraries, improving SEO, and enhancing accessibility.
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.
