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

8 findings rated critical or high. Fix these first.

  1. 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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  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 business operates primarily as an online news publisher with revenue streams from advertising and premium subscriptions. Its government affiliation and long domain history since 1997 reinforce its market position and legitimacy. The company leverages partnerships with advertising networks like Vads.vn and media content providers such as Sohatv.vn. The target audience is broad, encompassing Vietnamese citizens interested in current affairs and diverse news topics. The website's extensive category structure and multimedia content indicate a mature digital media operation with strong brand consistency and trust signals.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and no exposed sensitive data. It uses multiple third-party analytics and advertising scripts, which necessitate ongoing security monitoring. The absence of explicit security policies, incident response contacts, and cookie consent mechanisms indicates gaps in compliance and user privacy protection. Security headers such as Content-Security-Policy and X-Frame-Options are not detected, representing an area for enhancement. Overall, the site is secure but could benefit from formalized security and privacy documentation and improved header configurations.

Recommendations

  1. Implement and publish a comprehensive privacy policy and cookie consent mechanism to improve GDPR compliance.
  2. Add explicit security headers like Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to enhance browser security.
  3. Establish and disclose an incident response policy with dedicated contact channels for security issues.
  4. Regularly audit and update third-party scripts to mitigate risks from external dependencies.
  5. Enhance accessibility features and provide clear data retention policies to improve user trust and compliance.

Technical notes

Notes

The website uses a custom or proprietary CMS with a modern tech stack including Google Analytics, Google Tag Manager, Microsoft Clarity, and Facebook Pixel for analytics and marketing. It employs lazy loading for images and responsive design for mobile devices. Performance is moderate with asynchronous loading of scripts. SEO is well addressed with proper meta tags, Open Graph data, and JSON-LD structured data for organization and website schema. Hosting provider details are not explicitly identified. The site could improve accessibility and security header implementation to reduce technical risks.
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.
