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

Renesas Electronics Corporation is a global leader in microcontrollers, analog, power, and SoC products, delivering embedded design innovation for a wide range of industries. The company targets embedded systems developers and technology companies with a comprehensive portfolio of semiconductor products and design resources. The website reflects a mature, enterprise-level business with a strong market position and extensive product offerings. Technically, the website is built on Drupal 10, hosted behind Cloudflare, and utilizes modern web technologies including Google Tag Manager and New Relic for monitoring. The site is well-structured, mobile-optimized, and SEO-friendly, providing a professional user experience. However, the absence of a valid SSL certificate and incomplete security configurations represent significant security concerns. From a security perspective, while several security headers are implemented, the lack of HTTPS and TLS support critically undermines the site's security posture. No explicit incident response or security policy pages were found, and cookie consent mechanisms are absent despite GDPR compliance indications. The domain is mature and registered with a reputable registrar, consistent with the company's profile. Overall, the site is professionally maintained with strong business credibility but requires urgent improvements in SSL/TLS deployment and privacy compliance mechanisms to enhance security and user trust.

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. 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

    • 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

  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

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

Renesas operates as an essential entity in the semiconductor technology sector, focusing on embedded solutions for automotive, industrial, consumer electronics, and communications infrastructure. Its business model is B2B, serving engineers and companies requiring microcontrollers and analog products. The company maintains a strong partnership ecosystem, including dedicated community and training platforms. Growth indicators include frequent product launches, events, and a comprehensive support infrastructure. The website content and structure support a global enterprise with a focus on innovation and sustainability. Competitive advantages include a broad product portfolio, industry leadership, and extensive design resources. Revenue streams likely derive from product sales, licensing, and support services. The company’s digital presence is mature, leveraging advanced analytics and marketing tools, although some privacy compliance aspects need enhancement.

Security posture

The current security posture of the website is moderate but with critical gaps. The presence of security headers like Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options indicates awareness of security best practices. However, the absence of a valid SSL certificate and disabled TLS protocols severely compromise data confidentiality and integrity. No OCSP stapling or session resumption mechanisms are enabled, reducing resilience against certain attacks. No explicit security or incident response policies are publicly available, and no dedicated security contact channels were found. Cookie consent and GDPR compliance mechanisms are incomplete, which may expose the company to regulatory risks. Overall, the site requires immediate remediation of SSL/TLS issues and enhancement of privacy and security disclosures to improve its security maturity.

Recommendations

  1. Install and maintain a valid SSL/TLS certificate to enable HTTPS and secure communications.
  2. Enable modern TLS protocols (TLS 1.2 or higher) and configure OCSP stapling for improved security and performance.
  3. Implement a cookie consent mechanism to comply with GDPR and enhance user privacy transparency.
  4. Publish clear security policies and incident response procedures, including dedicated security contact information.
  5. Regularly audit and update security headers and privacy policies to maintain compliance and trust.
Technical notes

Notes

The website uses Drupal 10 CMS, hosted behind Cloudflare CDN, and integrates Google Tag Manager and New Relic for analytics and monitoring. The tech stack includes JavaScript libraries such as Glider.js and MicroModal, and Algolia for search functionality. The site is mobile-optimized and accessible, with good SEO practices including meta tags and structured data (JSON-LD). Performance metrics are moderate, with caching enabled via Cloudflare but no explicit load time data available. The site architecture supports a large enterprise with complex navigation and content structures. Technical risks include the lack of SSL/TLS security and potential privacy compliance gaps. Opportunities exist to modernize security configurations and enhance user privacy 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.
