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

2Sao.vn is a Vietnamese entertainment news website operated by Công ty Cổ phần truyền thông VietNamNet. It provides up-to-date news on showbiz, music, film, fashion, and related entertainment topics targeting a general audience interested in Vietnamese and international celebrity news. The site is well-established with a consistent brand presence and clear business registration, positioning itself as a popular media outlet in Vietnam. Technically, the website uses modern JavaScript libraries, Google Tag Manager, and multiple advertising and tracking services to monetize and analyze user engagement. Mobile optimization and SEO practices are good, though accessibility features are basic. Security posture is adequate with HTTPS and some security meta tags, but lacks comprehensive security headers and published security policies. Privacy compliance is weak due to missing privacy and cookie policies. Overall, the domain registration data aligns well with the business claims, indicating legitimacy and trustworthiness.

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. 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';…

  3. 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

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

The website operates in the media sector focusing on entertainment news, leveraging advertising networks such as Vads, Google AdSense, and Admicro for revenue. It targets Vietnamese-speaking audiences interested in showbiz and lifestyle content. The business model is content-driven with monetization primarily through ads and tracking-based marketing tools. The company maintains active social media presence on Facebook, YouTube, and TikTok, enhancing audience engagement. The site shows moderate technical maturity with custom CMS infrastructure and integration of multiple analytics and marketing platforms. No suspicious or privacy-protected WHOIS data suggests transparency and established market presence.

Security posture

The website enforces HTTPS and uses some security-related meta tags to prevent content translation and archiving. However, it lacks advanced security headers like Content-Security-Policy, X-Frame-Options, and HSTS which are recommended for enhanced protection. No explicit security or incident response policies are published, and no vulnerability disclosure or security.txt files are found. The use of multiple third-party scripts and ad networks increases the attack surface, necessitating stronger security controls. No vulnerabilities or exposed sensitive data were detected in the HTML content. Privacy compliance is insufficient, with no visible cookie consent mechanisms or privacy policies, which may pose regulatory risks under GDPR or similar frameworks.

Recommendations

  1. Publish a comprehensive privacy policy and cookie policy with clear GDPR compliance statements.
  2. Implement a cookie consent mechanism to comply with privacy regulations.
  3. Add security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  4. Publish a security policy and incident response contact information to improve transparency and trust.
  5. Conduct regular security audits of third-party scripts and advertising integrations to minimize risks.

Technical notes

Notes

The website uses a custom CMS platform with integration of modern JavaScript libraries including CryptoJS, Swiper.js, and tracking tools like Google Tag Manager and Facebook Pixel. It leverages multiple ad networks for monetization and uses CDN services for hosting static assets. The site is mobile optimized with responsive design and preconnect/dns-prefetch hints for performance. SEO is supported by proper meta tags, Open Graph, and JSON-LD structured data. Accessibility is basic but functional. Performance is moderate, with potential improvements in script loading and resource optimization. The technical stack is typical for a media publishing site but could benefit from enhanced security and privacy features.
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.
