Risk levelMedium

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

The website www.hinet.net serves as the official portal for Chunghwa Telecom's HiNet internet services, the largest ISP in Taiwan. It offers broadband internet, fiber optic (HiNet光世代), ADSL, online applications, and email services, extending to enterprise, government, cybersecurity, and cloud network applications. The site is professionally designed with good content quality and clear navigation, targeting a general audience in Taiwan. Technically, it employs modern web technologies including jQuery, Swiper, Google Analytics, and Google Tag Manager, with good mobile optimization and SEO practices. Security posture is solid with HTTPS enabled and no visible vulnerabilities, though security headers and explicit privacy/cookie policies are absent. WHOIS data is unavailable, which limits domain registration trust verification but the website branding and content strongly indicate legitimacy. Overall, the site is a reliable and professional digital presence for a major telecommunications provider.

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

3 findings rated critical or high. Fix these first.

  1. 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"

  2. 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

HiNet is positioned as Taiwan's leading ISP under Chunghwa Telecom, offering a comprehensive range of internet services including high-speed fiber and ADSL. The business model focuses on consumer broadband services and extends to enterprise and government sectors with cybersecurity and cloud networking solutions. The website reflects a mature digital presence with integration of analytics and marketing tools, indicating a data-driven approach to customer engagement. The absence of explicit contact information and privacy policies suggests areas for improvement in customer transparency and compliance. The company benefits from strong brand recognition and market dominance in Taiwan's telecommunications sector.

Security posture

The website demonstrates a good security baseline with HTTPS enforced and no exposed sensitive data in the HTML content. Use of asynchronous loading for analytics scripts reduces performance impact. However, the lack of security headers such as Content-Security-Policy and X-Frame-Options is a gap. No vulnerability disclosures or incident response contacts are provided, which could hinder rapid response to security events. Privacy compliance is weak due to missing privacy and cookie policies and consent mechanisms. Overall, the security posture is adequate for a large ISP but could be enhanced by implementing recommended headers, explicit policies, and incident response information.

Recommendations

  1. Implement comprehensive privacy and cookie policies with clear GDPR compliance and user consent mechanisms.
  2. Add security headers including Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and Strict-Transport-Security.
  3. Publish clear contact information for security incidents and designate an incident response team contact.
  4. Regularly audit third-party libraries and scripts for vulnerabilities and update accordingly.
  5. Enhance transparency by providing business contact details and data retention policies.

Technical notes

Notes

The website uses a modern technology stack with jQuery 3.5.1, Swiper for UI components, and Google Analytics and Tag Manager for tracking. Fonts include Roboto and Noto Sans TC, supporting multilingual content. The site is mobile responsive and optimized for SEO with proper meta tags and Open Graph data. Performance is moderate with asynchronous script loading. No CMS or hosting provider is explicitly identified. Technical debt appears low, but the absence of security headers and privacy compliance features indicates areas for modernization. Overall, the infrastructure supports a stable and professional user experience.
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.
