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

UD在线工具箱 is a Chinese-language online platform offering a comprehensive suite of free utility tools including encryption, encoding, image processing, PDF handling, and various lifestyle and webmaster tools. The website targets general internet users seeking convenient online utilities. Technically, the site is built on the Z-Blog CMS platform, utilizing jQuery and the layui framework, and is served over HTTPS with moderate performance and good mobile optimization. Security posture is adequate with HTTPS enforced, but lacks advanced security headers and formal privacy or cookie policies. The absence of WHOIS data raises questions about domain registration legitimacy, although the site content is accessible and appears legitimate. Overall, the platform provides valuable free tools but would benefit from improved transparency and security practices.

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

4 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. 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 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 website operates as a free online tools provider in the technology sector, focusing on utility tools for a Chinese-speaking audience. It offers a broad range of services from encryption to lifestyle calculators, positioning itself as a general utility platform rather than a niche specialist. The business model appears to be ad-supported or tracking-based, with third-party analytics scripts detected. No clear business registration or contact information is provided, limiting trust signals. The platform's market position is that of a small-scale, general-purpose online tools provider with consistent branding and good content quality.

Security posture

The site enforces HTTPS and uses modern JavaScript libraries, indicating a baseline security maturity. However, it lacks critical security headers such as Content-Security-Policy and X-Frame-Options, which could improve protection against common web attacks. No sensitive data exposure or vulnerable libraries were detected. The absence of privacy and cookie policies, as well as incident response contacts, indicates gaps in compliance and security governance. The site would benefit from implementing formal security policies, improving header configurations, and providing clear contact channels for security incidents.

Recommendations

  1. Implement and publish a comprehensive privacy policy and cookie consent mechanism to improve compliance and user trust.
  2. Add security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to enhance security posture.
  3. Provide clear contact information and establish an incident response process to handle security issues effectively.
  4. Regularly audit and update third-party scripts and libraries to mitigate vulnerabilities.
  5. Consider registering the domain with transparent WHOIS information to improve legitimacy and trust.

Technical notes

Notes

The website is built on the Z-Blog CMS platform with jQuery 2.2.4 and the layui UI framework. It uses HTTPS and serves content with a responsive design optimized for mobile devices. Performance is moderate, with no major errors or broken elements detected. SEO is supported by appropriate meta tags and keywords. The site includes third-party tracking scripts from aizhantj.com. There is room for improvement in accessibility and security header implementation. The technical infrastructure is adequate for a small-scale online tools platform but could be modernized and hardened for better security and compliance.
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.
