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

Dahua Technology is a globally recognized enterprise specializing in video-centric AIoT solutions and services, focusing on city and enterprise sectors. The company positions itself as a leader in intelligent security technology, offering a broad range of products and services tailored to large-scale security and surveillance needs. Their digital presence is built on modern web technologies including Nuxt.js and integrates major analytics and marketing tools such as Google Analytics and Facebook Pixel. The website demonstrates a high level of professionalism, with comprehensive privacy, cookie, and terms of service policies, reflecting a mature approach to compliance and user data protection. Security measures such as HTTPS and security headers are properly implemented, indicating a strong security posture. However, the absence of publicly available WHOIS registration data introduces some uncertainty regarding domain legitimacy, which slightly impacts the overall trust score.

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

5 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

    • High

      No SPF record found

      SPF helps prevent email spoofing

      What to do: Add SPF record: "v=spf1 include:_spf.yourmailprovider.com ~all"

  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 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

  3. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

  4. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

Dahua Technology operates primarily in the technology sector, serving industries such as transportation, energy, and government. Their business model is B2B, focusing on providing AIoT and video surveillance solutions to enterprise clients and city planners. The company holds recognized certifications like ISO 9001, ISO 14001, and ISO 27001, which bolster their credibility. The website content and structure suggest a large enterprise with a global footprint and a well-established partnership ecosystem. Their marketing and analytics infrastructure supports moderate user tracking, balanced with privacy compliance efforts. The company targets professional and institutional customers rather than consumers, emphasizing security and technological innovation.

Security posture

The website enforces HTTPS and includes key security headers such as Strict-Transport-Security, X-Frame-Options, and Content-Security-Policy, which are best practices for web security. No exposed sensitive data or vulnerable libraries were detected in the analysis. The presence of a security resource center and incident response contact emails indicates an organizational commitment to security and incident management. However, the lack of a security.txt file and limited explicit incident response documentation on the site suggest room for improvement in vulnerability disclosure transparency. Overall, the security posture is strong but could be enhanced with additional public-facing security communication.

Recommendations

  1. Implement a security.txt file to formalize vulnerability disclosure and improve transparency.
  2. Enhance accessibility features to improve compliance and user experience for all users.
  3. Regularly audit and update third-party scripts and analytics tools to mitigate potential vulnerabilities.
  4. Increase visibility of incident response procedures and contacts to build trust with security researchers and customers.
  5. Consider publishing domain registration details or ensuring WHOIS data is publicly available to improve domain legitimacy perception.

Technical notes

Notes

The website is built using modern JavaScript frameworks, specifically Nuxt.js, which supports server-side rendering and SEO optimization. It integrates widely used analytics and marketing tools such as Google Tag Manager, Google Analytics, and Facebook Pixel, enabling effective user behavior tracking and marketing campaigns. Performance is moderate, with good mobile optimization and basic accessibility features. The site uses a custom CMS or framework rather than a common CMS like WordPress. Hosting provider details are not explicitly identified. The technical infrastructure supports a professional and scalable web presence but could benefit from enhanced accessibility and performance tuning.
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.
