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

The website '刀客在线工具' is a Chinese-language online platform offering a broad range of free practical and educational tools, including dictionaries, calculators, translation services, and various lookup utilities. It targets Chinese-speaking users seeking convenient online resources for learning and daily life. The business model appears to be providing free access to these tools without evident monetization or advertising. Technically, the site uses jQuery and the Layui framework, with a responsive design suitable for both desktop and mobile users. However, there is no evidence of HTTPS or advanced security measures in the provided data, and no privacy or cookie policies are present, which may affect user trust and compliance with data protection regulations. The WHOIS data is missing or unavailable, which raises concerns about domain registration transparency and legitimacy. Overall, the site is content-rich and functional but lacks critical security and compliance features.

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

6 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 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 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

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 platform occupies a niche in the Chinese online educational and utility tool market, offering a comprehensive suite of tools that cater to students, educators, and general users interested in language, culture, and practical calculations. The absence of clear business registration or contact information limits the ability to assess its corporate structure or revenue streams. The site links to many well-known external domains for search and media but does not appear to have formal partnerships or subsidiaries. Growth potential exists given the breadth of tools, but trust and compliance improvements are necessary to enhance credibility and user confidence.

Security posture

The security posture of the website is weak based on the available data. There is no indication of HTTPS usage or security headers, no privacy or cookie policies, and no incident response or security contact information. The lack of WHOIS transparency further reduces trust. No known vulnerabilities or malicious content were detected in the content, but the absence of modern security practices and compliance documentation is a significant gap. The site should prioritize implementing SSL/TLS, security headers, and privacy compliance to improve its security maturity and reduce risk exposure.

Recommendations

  1. Implement HTTPS with a valid SSL certificate to secure user connections and improve trust.
  2. Publish comprehensive privacy and cookie policies to comply with GDPR and other data protection regulations.
  3. Add clear contact information including business address, phone number, and email for support and security incidents.
  4. Introduce security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  5. Regularly audit and update third-party libraries and frameworks to mitigate vulnerabilities and improve performance.

Technical notes

Notes

The website uses a traditional web stack with jQuery and Layui for UI components, along with Font Awesome for icons. The site is structured with clear navigation and a responsive design, supporting both desktop and mobile devices. Performance appears moderate, with lazy loading of images and efficient layout. However, there is no evidence of a modern CMS or advanced backend technologies. The absence of HTTPS and security headers is a technical risk. SEO is supported by meta tags and structured content, but accessibility features are basic. Hosting provider and infrastructure details are not available from the data.
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.
