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

ZLONGAME is a prominent mobile game developer and publisher headquartered in Beijing, China, with a strong presence across Asia and global markets. The company focuses on anime-themed and MMO mobile games, offering localized versions for multiple languages and regions. Their website reflects a professional and consistent brand image, targeting a broad audience of mobile gamers worldwide. Technically, the site uses established JavaScript libraries like jQuery and SuperSlide, hosted on Alibaba Cloud, indicating a stable infrastructure. However, the site lacks modern security headers and explicit privacy or cookie policies, which are critical for compliance and user trust. The absence of forms and minimal tracking scripts suggests a low data collection footprint, but also a lack of transparency in privacy practices. Overall, the website is functional and credible but would benefit from enhanced security and compliance features.

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. 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. 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

ZLONGAME operates in the competitive mobile gaming industry with a focus on Asian and global markets. Their business model centers on developing and publishing anime-themed and MMO mobile games, leveraging multiple localized portals to reach diverse audiences. The company has demonstrated rapid growth since its founding in 2015, with a broad portfolio of games and regional offices. Partnerships with domains like game-beans.com indicate strategic alliances for regional market penetration. The lack of visible monetization or advertising scripts suggests revenue primarily from game sales or in-app purchases. The company’s digital presence is professional but could improve transparency and compliance to strengthen market trust.

Security posture

The website employs HTTPS and is hosted on a reputable cloud provider, which provides a baseline of security. However, the absence of DNSSEC and security headers such as Content Security Policy, X-Frame-Options, and HSTS reduces the overall security posture. No forms or sensitive data collection points are present, minimizing immediate risk exposure. The lack of a published security policy, incident response contacts, or vulnerability disclosure program indicates limited maturity in security governance. To improve, the company should implement standard security headers, enable DNSSEC, and publish clear security and privacy policies to align with best practices and regulatory requirements.

Recommendations

  1. Implement comprehensive privacy and cookie policies with clear GDPR compliance statements.
  2. Add security headers including CSP, HSTS, X-Frame-Options, and X-Content-Type-Options to enhance protection.
  3. Enable DNSSEC on the domain to improve DNS security.
  4. Publish a vulnerability disclosure policy and incident response contact information to improve security transparency.
  5. Enhance accessibility features and include social media or additional contact channels to improve user engagement and trust.

Technical notes

Notes

The website uses legacy but stable JavaScript libraries such as jQuery 1.11.3 and SuperSlide 2.1.2, indicating a somewhat dated but functional tech stack. The hosting on Alibaba Cloud is consistent with the company’s geographic focus. The site is mobile responsive and well-structured with good SEO meta tags. However, the lack of modern frameworks or CMS suggests potential technical debt and limited scalability. Performance is moderate with no explicit optimization scripts detected. Accessibility is basic, with room for improvement in ARIA roles and semantic markup. Overall, the technical implementation supports the business needs but would benefit from modernization and enhanced security controls.
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.
