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. 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

    • 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

  2. 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

  3. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • High

      Unregistered MX Record

      MX record points to unregistered domain: smtp.seanet.vn

      What to do: Remove or fix MX record pointing to unregistered domain

      • RFC 5321 §5.1
      • NIS2 21(2)(i)
      • IR 2024/2690 12.4: Implementing Regulation (EU) 2024/2690, Annex point 12.4: Asset inventory
      • NIST CM-8: NIST SP 800-53 Rev. 5 CM-8: System Component Inventory

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

  • Email security: did not complete in this scan.
  • 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

SeABank operates in the Vietnamese banking sector providing internet banking services for both individual and corporate clients. The business model focuses on digital banking solutions, facilitating online access to banking products. The company targets a broad customer base including personal banking customers and enterprises, positioning itself as a modern financial institution. The website reflects a professional brand image consistent with a large financial entity. Revenue streams likely include traditional banking fees and digital service charges. The partnership ecosystem includes internal domains for corporate banking. Growth indicators are not explicit but the digital presence suggests ongoing investment in online banking capabilities.

Security posture

The current security posture is moderate. The site uses HTTPS, which is mandatory for banking services, and does not expose sensitive data or forms on the landing page, reducing attack surface. However, the absence of security headers such as Content Security Policy, HSTS, and X-Frame-Options is a gap. No incident response or vulnerability disclosure information is provided, limiting transparency. Privacy compliance is basic with linked policies but no cookie consent or GDPR indicators. The lack of visible analytics or tracking reduces privacy risks but also limits user behavior insights. Overall, the security culture appears cautious but could benefit from enhanced transparency and technical controls.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, and X-Frame-Options to harden the site against common web attacks.
  2. Add a visible cookie policy and consent mechanism to comply with privacy regulations and improve user trust.
  3. Publish clear incident response and vulnerability disclosure contacts to enhance transparency and security readiness.
  4. Improve accessibility features to meet international standards and broaden user inclusivity.
  5. Incorporate SEO best practices and structured metadata to improve search engine visibility and user engagement.

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.
