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

TENTEN is a prominent Vietnamese domain registrar and hosting provider offering a comprehensive suite of services including domain registration for .VN and international domains, various hosting solutions, cloud servers, email servers, SSL certificates, and AI-powered tools. The company holds a strong market position in Vietnam, supported by awards from VNNIC and partnerships with major financial institutions. Their website reflects a professional and consistent brand image targeting both individual and business customers within Vietnam. Technically, the site employs modern web technologies such as Bootstrap, jQuery, and multiple analytics and marketing tools, hosted likely by GMO Japan. Security posture is solid with HTTPS and input sanitization, though lacking explicit security policies and vulnerability disclosures. Privacy compliance is basic, with no visible privacy or cookie policies and no consent mechanisms. Overall, the site is well-designed, user-friendly, and trustworthy, but could improve transparency around privacy and security policies.

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.

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

TENTEN operates primarily in the technology sector focusing on domain registration and web hosting services. Their business model revolves around providing essential internet infrastructure services to Vietnamese individuals and enterprises, with additional offerings in cloud computing and AI tools to enhance digital presence. The company demonstrates competitive advantages through official registrar status, recognized awards, and a broad service portfolio. Revenue streams likely include domain sales, hosting subscriptions, cloud services, and value-added services like SSL and email solutions. The target customer segments range from small businesses to larger enterprises requiring reliable internet services. Partnerships with banks and media outlets indicate a strong ecosystem and market trust. The company shows growth orientation with continuous service expansion and AI integration.

Security posture

The website exhibits a mature security posture with mandatory HTTPS encryption and no visible exposure of sensitive data. Input fields have basic sanitization to prevent injection of special characters. However, the absence of security headers, security policy documentation, incident response contacts, and vulnerability disclosure mechanisms indicates gaps in comprehensive security governance. The use of multiple tracking and marketing scripts increases the attack surface but is common in commercial websites. Privacy compliance is minimal, lacking cookie consent banners and privacy policies, which could pose regulatory risks. Overall, the security maturity is moderate, with room for improvement in policy transparency and technical safeguards.

Recommendations

  1. Publish a comprehensive privacy policy and cookie policy with GDPR compliance details.
  2. Implement a cookie consent mechanism to inform users and obtain consent for tracking.
  3. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-XSS-Protection.
  4. Create and publish a security policy and incident response contact information.
  5. Establish a vulnerability disclosure program or security.txt file to encourage responsible reporting.

Technical notes

Notes

The website uses a modern and widely adopted technology stack including Bootstrap for responsive design, jQuery for DOM manipulation, and slick and swiper libraries for sliders. It integrates Google Fonts for typography and multiple analytics and marketing tools such as Google Analytics, Microsoft Clarity, Facebook Pixel, and Bing UET for user behavior tracking and advertising. Hosting appears to be provided by GMO Japan, inferred from included scripts. Performance is moderate with some optimizations like preconnect and preload hints. Mobile optimization is good with responsive layouts and adaptive images. Accessibility is basic but could be enhanced. SEO is supported by proper meta tags and structured data in JSON-LD format. The site is well-structured but lacks some modern accessibility and security best practices.
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.
