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

Tatiao.com is a Chinese-language online platform offering a comprehensive suite of free utility tools spanning education, finance, life services, mathematics, and webmaster utilities. Established in 2009, it targets a broad general audience seeking practical and interesting online tools to assist with work and study. The website maintains a consistent brand presence and provides a well-structured, mobile-optimized user experience with good navigation and relevant content. Technically, the site uses jQuery, Baidu Analytics, and icon fonts, hosted by Alibaba Cloud, reflecting a moderate level of digital maturity. However, it lacks modern security headers and DNSSEC, and does not publish privacy or cookie policies, indicating gaps in privacy compliance and security best practices. Contact information is minimal, limited to a QQ number and a search form, with no explicit email or phone contacts. Overall, the site is safe for general audiences and does not contain adult or questionable content.

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

10 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. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MSSQL

      Port 1433 (MSSQL) is publicly accessible - MSSQL - Database server

      What to do: Immediately restrict access to MSSQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection
    • Critical

      Critical Service Exposed: RDP

      Port 3389 (RDP) is publicly accessible - RDP - Remote Desktop, prime ransomware target

      What to do: Immediately restrict access to RDP using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  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"

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 · found on this site
  • 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

Tatiao.com operates as a niche provider of free online utility tools primarily for Chinese users. Its business model appears to be content and tool aggregation without direct monetization visible on the homepage. The extensive friendly links network suggests partnerships with related utility and service sites, enhancing its ecosystem. The site's longevity since 2009 and consistent content updates indicate stable operations. However, the lack of formal privacy and security policies may limit trust from more security-conscious users. The platform's focus on education and practical tools positions it well within the Chinese online utility market, but it faces competition from larger multi-tool platforms. Growth opportunities could include enhanced user engagement, monetization strategies, and improved compliance.

Security posture

The website employs HTTPS and is hosted on Alibaba Cloud, which provides a baseline of security. However, the absence of DNSSEC and security headers such as Content-Security-Policy, X-Frame-Options, and HSTS reduces its defense against common web attacks. No privacy or incident response policies are published, and no vulnerability disclosure mechanisms are evident. The use of Baidu Analytics introduces moderate user tracking without clear privacy disclosures, potentially impacting GDPR compliance. Forms on the site are minimal and do not appear to collect sensitive personal data, reducing immediate risk. Overall, the security posture is moderate but could be significantly improved by implementing standard security headers, publishing privacy and cookie policies, and establishing incident response contacts.

Recommendations

  1. Implement comprehensive privacy and cookie policies to improve transparency and compliance.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and HSTS to enhance protection against web attacks.
  3. Enable DNSSEC for the domain to improve DNS security.
  4. Publish incident response and vulnerability disclosure information to build trust and readiness.
  5. Enhance contact information availability with official email addresses and phone numbers for support and security reporting.

Technical notes

Notes

The website uses a traditional tech stack with jQuery 3.3.1 and Baidu Analytics for tracking. It relies on static CSS and JavaScript files hosted on its domain, with icon fonts for UI elements. The site is mobile optimized and has good SEO metadata including keywords and description tags. No CMS or advanced frameworks are detected, suggesting a custom or lightweight platform. Hosting is provided by Alibaba Cloud, a reputable provider. Performance is moderate, with no explicit indicators of slow loading but also no advanced optimization techniques observed. Accessibility features are basic, and no ARIA or other accessibility tags are evident. The site could benefit from modernization including improved accessibility and performance optimizations.
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.
