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

Nhóm Văn Lang operates as a small non-profit organization serving the Vietnamese diaspora community in the Czech Republic. The website functions primarily as a news and advocacy platform, publishing open letters, event announcements, and community news related to human rights and Vietnamese cultural issues. The organization appears to have been active since at least 2012, with a focus on community engagement and political advocacy. Technically, the website is built on ASP.NET Web Forms with jQuery and uses a custom CMS. The site lacks modern web features such as mobile optimization, advanced SEO, and accessibility enhancements. Security posture is weak, with no visible HTTPS enforcement or security headers, and no privacy or cookie policies are present, indicating potential compliance gaps. Overall, the site is functional but basic, with room for significant improvements in security, privacy, and technical modernization.

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

10 findings rated critical or high. Fix these first.

  1. GDPR outside view

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

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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

  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"

      • OWASP A04:2025
      • ASVS V3.4.1

      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

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 organization targets Vietnamese expatriates and human rights advocates, focusing on community news and political activism. Its niche positioning as a diaspora advocacy group limits its market scope but strengthens its community relevance. The business model is non-profit and content-driven, relying on information dissemination rather than commercial revenue. The website's partnership ecosystem is minimal, with no external business partners or subsidiaries identified. Growth indicators are limited, with content updates continuing but no evident expansion or monetization strategies. The organization benefits from a consistent domain registration and a clear focus on its target audience.

Security posture

The website demonstrates a low security maturity level. Absence of HTTPS enforcement and security headers exposes users to potential risks such as data interception and clickjacking. The lack of privacy and cookie policies indicates non-compliance with GDPR and related regulations, which could pose legal risks. No incident response or vulnerability disclosure mechanisms are present, limiting the organization's ability to respond to security events. The use of outdated ASP.NET Web Forms technology may also introduce vulnerabilities if not properly maintained. Overall, the security posture requires urgent improvements to protect user data and comply with regulations.

Recommendations

  1. Implement HTTPS with HSTS to secure all communications.
  2. Add comprehensive privacy and cookie policies to comply with GDPR.
  3. Deploy security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Introduce a vulnerability disclosure policy and incident response contact channels.
  5. Modernize the website technology stack to improve performance, security, and mobile responsiveness.

Technical notes

Notes

The website is built on legacy ASP.NET Web Forms technology with jQuery and a photo gallery plugin. The hosting is provided by INTERNET CZ, a Czech registrar and hosting provider. The site lacks mobile optimization and modern SEO practices, which may limit reach and user engagement. Performance is moderate but could be improved with updated frameworks and optimized assets. Accessibility features are minimal, potentially excluding some user groups. The absence of security headers and HTTPS enforcement represents a technical risk. Overall, the technical infrastructure is functional but outdated and requires modernization to meet current web standards and security best practices.
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.
