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. GDPR outside view

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

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

  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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

  3. 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';…

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

SeABank operates in the banking sector in Vietnam, serving retail and corporate customers. Its business model includes traditional banking services complemented by digital platforms such as SeANet and mobile apps. The bank leverages partnerships for premium customer services and recruitment. Its market position is strong within Vietnam, supported by a large capital base and diverse product portfolio. The website content and structured data reflect a focus on customer engagement and transparency. The bank's digital ecosystem includes multiple linked domains for specialized services, indicating a mature operational structure.

Security posture

The website demonstrates a baseline security posture with HTTPS enabled and no apparent exposure of sensitive information in the HTML content. However, there is no evidence of advanced security headers like CSP, HSTS, or X-Frame-Options. No incident response or vulnerability disclosure information is provided, which could be a gap in transparency and readiness. The absence of privacy and cookie policies also suggests incomplete compliance with data protection best practices. The use of modern frameworks reduces some risk, but continuous monitoring and enhancement of security controls are recommended.

Recommendations

  1. Implement and publish comprehensive privacy and cookie policies with consent mechanisms.
  2. Add security headers such as Content Security Policy, HSTS, and X-Frame-Options to enhance protection.
  3. Provide clear incident response and vulnerability disclosure contacts to improve transparency.
  4. Regularly audit and update third-party libraries to mitigate vulnerabilities.
  5. Enhance user trust by including certifications and compliance badges on the website.

It uses Swiper.js for interactive banners and Google Analytics for user tracking. The site is optimized for mobile devices and employs lazy loading for images and videos to improve performance. The structured data is well implemented using JSON-LD for local business, organization, and website schemas, aiding SEO. Hosting details are not explicit, but the use of CDN domains suggests a distributed content delivery approach. Overall, the technical infrastructure supports a fast, accessible, and SEO-friendly banking website.
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.
