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

4 findings rated critical or high. Fix these first.

  1. 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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

  2. GDPR outside view

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

    • 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

  3. 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 SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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.

Business context

Business profile

Poki holds a strong market position as a popular global online games portal with over 90 million monthly players. Its competitive advantage lies in offering instant-play games without friction such as downloads or sign-ups, appealing to a wide demographic. The revenue model is based on advertising partnerships and revenue sharing with game developers, enabling free access to users. The company maintains a developer platform to attract and publish new games regularly, supporting growth and content freshness. The ecosystem includes partnerships with major ad networks like DoubleClick and InMobi, and uses Google Analytics for insights. The platform is localized in many languages, indicating a global reach. Strategic observations include the need to enhance security transparency by publishing a dedicated security policy and vulnerability disclosure program.

Security posture

The website exhibits a mature security posture with enforced HTTPS, presence of key security headers (HSTS, CSP, X-Frame-Options), and no exposed sensitive data in the HTML. The domain registration is stable and protected against unauthorized changes. However, DNSSEC is not enabled, which is a recommended improvement to prevent DNS spoofing. No security.txt or incident response information is published, which could improve transparency and readiness. Privacy policies are comprehensive and GDPR compliant, with cookie consent mechanisms in place. No vulnerabilities or malware indicators were detected. Overall, the security maturity is good but could benefit from formalized security disclosures and DNSSEC activation.

Recommendations

  1. Enable DNSSEC on the poki.com domain to enhance DNS security.
  2. Publish a dedicated security policy and incident response page to improve transparency.
  3. Implement a vulnerability disclosure program or security.txt file to facilitate responsible reporting.
  4. Continue maintaining strong privacy compliance and update policies as regulations evolve.
  5. Regularly audit third-party scripts and advertising partners to minimize tracking risks and improve user trust.

Technical notes

Notes

The website uses a modern React-based frontend with chunked CSS and JavaScript assets served via a CDN (a.poki-cdn.com). DNS is managed via Cloudflare, providing resilience and performance benefits. Google Tag Manager and InMobi CMP scripts are used for analytics and consent management. The site is well optimized for mobile and desktop with responsive design and accessibility considerations. Performance is fast with efficient asset loading and caching. SEO is supported by comprehensive meta tags, Open Graph, and alternate language links. No CMS is explicitly detected, suggesting a custom or proprietary platform. Hosting is stable with Amazon Registrar as domain registrar and Cloudflare DNS. Overall, the technical infrastructure is modern, scalable, and performant with minor opportunities for DNS security improvements.
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.
