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

1 finding rated critical or high. Fix these first.

  1. 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.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

MediaTek holds a leading market position as the #1 global provider of smartphone chipsets and a key player in smart home, IoT, and automotive semiconductor markets. Their business model focuses on semiconductor design and licensing, targeting device manufacturers and technology partners. The company maintains a strong investor relations presence with detailed financial disclosures and corporate governance information. Partnerships and subsidiaries such as MediaTek Ventures and MediaTek Foundation support innovation and sustainability initiatives. The website content and linked domains indicate a robust ecosystem and strategic focus on emerging technologies like AI and 5G. Growth indicators include recent product launches and participation in major industry events like MWC 2025. The company leverages HubSpot for marketing automation and analytics, reflecting a modern approach to digital engagement.

Security posture

The website demonstrates a solid security posture with HTTPS enforced and multiple security headers likely in place due to HubSpot hosting. Consent management for cookies and integration with Google Consent Mode show attention to privacy compliance. However, the site lacks publicly available security policies, incident response procedures, and vulnerability disclosure programs, which are important for transparency and trust. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The absence of direct security contact emails or a security.txt file limits incident reporting capabilities. Overall, the security maturity is good but could be enhanced by publishing formal security documentation and contact channels.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and compliance.
  2. Implement and publish a vulnerability disclosure policy or security.txt file.
  3. Provide direct security contact emails (e.g., security@mediatek.com) for incident reporting.
  4. Enhance transparency on data retention and privacy practices beyond cookie consent.
  5. Regularly audit and update third-party scripts to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built on the HubSpot CMS platform, utilizing modern front-end technologies including HTML5, CSS3, JavaScript, and libraries such as Swiper.js and Slick Slider for UI components. It integrates Google Tag Manager and Google Analytics for tracking and marketing purposes, with consent management implemented to comply with GDPR. The site is mobile-optimized with responsive design and accessibility considerations. Hosting appears to be managed by HubSpot, providing reliable performance and security features. The technical infrastructure supports a fast, professional user experience with clear navigation and rich multimedia content. Opportunities exist to improve technical documentation of security and privacy practices and to enhance direct communication channels for users and partners.
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.
