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

Tatiao.com is a Chinese-language online platform offering a comprehensive collection of free, practical, and interesting online tools spanning education, finance, life services, mathematics, and webmaster utilities. The website targets a general audience seeking utility tools for work and study, positioning itself as a niche provider of diverse online calculators, dictionaries, converters, and reference tools. The business model appears to be based on free access, likely monetized through advertising and partnerships. Technically, the website is hosted by Alibaba Cloud and uses HTTPS with a moderate performance profile. It employs jQuery and Baidu Analytics for functionality and user tracking. The site is mobile-optimized and has a clear navigation structure, though it lacks advanced SEO and accessibility features. No CMS or major frameworks are detected, indicating a custom or lightweight implementation. From a security perspective, the site uses HTTPS but lacks DNSSEC and important security headers, which reduces its security posture. There is no visible privacy, cookie, or terms of service policy, indicating compliance gaps with privacy regulations such as GDPR. No incident response or vulnerability disclosure information is provided. The domain registration is consistent and long-standing, registered with a reputable registrar, Alibaba Cloud, supporting legitimacy. Overall, the website is functional and provides valuable tools but requires improvements in privacy compliance, security hardening, and transparency to enhance trust and regulatory adherence. Strategic recommendations include implementing privacy and cookie policies with consent mechanisms, enabling DNSSEC, adding security headers, and providing clear contact and incident response information.

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

9 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 small-sized online utility tool provider in the education and finance sectors, offering a broad range of free online calculators, dictionaries, and converters primarily for Chinese users. Its competitive advantage lies in the breadth and diversity of tools available in one platform, catering to students, professionals, and webmasters. The business model is likely ad-supported, with partnerships evident from extensive external linking. The domain's age and stable registration indicate a mature presence. However, the lack of explicit business contact details and compliance documentation may limit trust and growth potential. The partnership ecosystem includes various related utility and design service sites, enhancing its service offering and reach.

Security posture

The website demonstrates a basic security posture with HTTPS enabled, ensuring encrypted communication. However, the absence of DNSSEC and critical security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options exposes it to potential risks like DNS spoofing and clickjacking. No privacy or cookie policies are present, indicating non-compliance with GDPR and other privacy regulations. The lack of incident response contacts and vulnerability disclosure mechanisms further weakens its security maturity. The use of third-party scripts like Baidu Analytics introduces moderate user tracking without visible consent, raising privacy concerns. Overall, the site requires significant improvements in security best practices and compliance to mitigate risks and enhance user trust.

Recommendations

  1. Implement a comprehensive privacy policy and cookie policy with explicit user consent mechanisms to comply with GDPR and other privacy laws.
  2. Enable DNSSEC for the domain to protect against DNS spoofing and improve domain security.
  3. Add essential security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web vulnerabilities.
  4. Provide clear incident response and security contact information to improve transparency and readiness for security events.
  5. Regularly audit and update third-party scripts and libraries to minimize vulnerabilities and enhance performance.

Technical notes

Notes

Tatiao.com is built using standard web technologies including HTML5, CSS, and jQuery 3.3.1, with Baidu Analytics integrated for user tracking. The site is hosted on Alibaba Cloud, a reputable provider, and uses HTTPS for secure communication. The website is mobile-optimized with responsive design elements and clear navigation. However, it lacks modern web frameworks or CMS platforms, suggesting a custom or minimalistic build. Performance is moderate, with no explicit indicators of advanced optimization or caching. SEO is basic, with meta keywords and descriptions present but no Open Graph or structured data detected. Accessibility features are minimal, and no ARIA roles or landmarks are evident. Overall, the technical infrastructure is functional but could benefit from modernization and enhanced security configurations.
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.
