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

The website vads.vn represents Công ty Cổ phần truyền thông VietNamNet's advertising platform, offering a comprehensive suite of advertising services across prominent Vietnamese media sites such as Vietnamnet, 2Sao, and Tintuconline. With over 14 years of experience and a large annual page view count, the company positions itself as a significant player in the Vietnamese digital advertising market. The platform provides diverse advertising formats including display ads, PR articles, sponsored content, multimedia, and video advertising, targeting advertisers seeking effective media exposure in Vietnam. Technically, the site employs common web technologies such as jQuery, Google Analytics, and Facebook SDK, with moderate performance and good mobile optimization. Security posture is adequate with HTTPS enabled and secure forms, but lacks important security headers and published security policies. Privacy compliance is weak due to absence of privacy and cookie policies. Overall, the site is professional and trustworthy but would benefit from enhanced security and privacy practices.

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

7 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 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"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  2. GDPR outside view

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

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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

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

Vads.vn operates as an essential media advertising entity under Vietnamnet JSC, serving a broad advertiser base in Vietnam. Its business model revolves around monetizing digital media through multiple advertising channels and formats. The company leverages its established market position, extensive audience reach, and diverse advertising options to attract clients. The presence of numerous case studies and prominent client logos indicates a strong partnership ecosystem and successful campaign track record. Growth indicators include high annual page views and a large number of successful campaigns. The platform's strategic partnerships with Vietnamnet and other media sites enhance its market reach and credibility.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and secure input forms. However, the absence of key security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options reduces its defense-in-depth posture. No explicit incident response or security policy information is published, indicating potential gaps in security governance and transparency. The use of third-party analytics and social SDKs introduces moderate tracking and privacy concerns. No vulnerabilities or exposed sensitive data were detected in the provided content. Compliance with GDPR or similar regulations is not evident due to missing privacy and cookie policies.

Recommendations

  1. Implement and publish comprehensive privacy and cookie policies with user consent mechanisms to improve compliance.
  2. Add security headers like Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to enhance security posture.
  3. Establish and disclose an incident response policy and contact channels for security issues.
  4. Regularly audit third-party scripts and tracking tools to minimize privacy risks and vulnerabilities.
  5. Enhance accessibility features and performance optimizations to improve user experience and SEO.

Technical notes

Notes

The website uses a traditional web technology stack including jQuery and Slick Carousel for UI components, Google Analytics and Facebook SDK for tracking, and standard CSS stylesheets. The site is mobile optimized and has a clear navigation structure. Performance is moderate, with asynchronous loading of analytics scripts. No modern JavaScript frameworks or CMS platforms were detected. Hosting provider details are not explicit. The site could benefit from modernizing its tech stack and improving accessibility compliance. The presence of multiple external domains for demos and PDFs indicates a distributed content delivery approach.
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.
