Security score

Risk levelHigh

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

123B is an online entertainment and gambling platform primarily targeting Vietnamese users, offering a wide range of services including casino games, sports betting, lottery, and various online games. The brand positions itself as a reputable and popular choice in the Asian market with millions of monthly visitors. Technically, the website is built on WordPress using the Flatsome theme, optimized for mobile devices and SEO, but lacks some advanced security headers and cookie consent mechanisms. Security posture is moderate with HTTPS enabled and some security practices mentioned, but improvements are needed in DNSSEC and security policy transparency. Overall, the domain registration is public but shows some inconsistencies with the brand name and domain age, suggesting recent domain acquisition or rebranding. The site is accessible without WAF blocking and provides clear contact information, but lacks explicit terms of service and cookie policies.

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. 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. 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

  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

The business operates in the online gambling sector, a highly competitive and regulated market. It leverages a multi-service model including casino, sports betting, lottery, and gaming to attract a broad adult audience. The company emphasizes customer support and security certifications such as MGA and PAGCOR to build trust. The website content and branding are consistent and professional, targeting Vietnamese players with localized content. The business model relies on user engagement through diverse gaming options and continuous feature updates. No direct partnerships or subsidiaries are identified from the domain data. Growth indicators include high monthly traffic and active customer support. Strategic observations suggest the need for enhanced compliance and security transparency to strengthen market position.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enabled and mentions of SSL encryption, firewall, and OTP for user protection. However, the absence of DNSSEC, lack of visible security headers, and missing cookie consent mechanisms indicate gaps in security best practices and privacy compliance. No incident response or vulnerability disclosure policies are published, which may affect readiness for security events. The WHOIS data is transparent but shows some inconsistencies that warrant monitoring. Overall, the security culture appears basic with room for improvement in formal policies and technical controls to meet higher compliance standards such as GDPR or NIS2.

Recommendations

  1. Enable DNSSEC to improve domain security and prevent DNS spoofing.
  2. Implement comprehensive security headers including CSP, HSTS, X-Frame-Options, and X-XSS-Protection.
  3. Add a cookie consent banner and detailed cookie policy to comply with privacy regulations.
  4. Publish clear incident response and vulnerability disclosure policies to enhance transparency and readiness.
  5. Conduct regular security audits and penetration testing to identify and remediate vulnerabilities.

Technical notes

Notes

The website is built on a modern WordPress CMS platform using the Flatsome theme, with jQuery and other standard libraries. It uses Cloudflare DNS services but does not enable DNSSEC, which is a missed security opportunity. The site is mobile-optimized and SEO-friendly with proper meta tags and structured data (JSON-LD). Performance is moderate with no major issues detected. Accessibility is basic but could be improved. The technical stack is standard for content-driven gambling sites but lacks advanced security configurations and privacy compliance features. There is no evidence of advanced analytics or tracking services beyond basic search functionality.
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.
