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

Neste is a leading global company specializing in renewable energy solutions, particularly sustainable aviation fuel and renewable diesel. The company positions itself as a pioneer in mitigating climate change and advancing the circular economy by refining waste and residues into high-quality renewable fuels and raw materials. Their market position is strong as a world leader in sustainable aviation fuel production, targeting businesses and consumers focused on sustainability. The website reflects a professional and consistent brand image with excellent content quality and user experience. Technically, the website is built on modern web technologies including React and Next.js, hosted likely on Google Cloud infrastructure. SEO and accessibility practices are well implemented, and the site is mobile optimized. However, performance data is limited but inferred to be moderate. The site uses cookie consent mechanisms and integrates marketing tools such as OneTrust and Visual Website Optimizer. From a security perspective, the site employs strong security headers and HSTS policies, but critically suffers from an invalid or missing SSL certificate and lack of enabled TLS protocols, which significantly undermines its security posture. No explicit security policies or incident response information are published, and no vulnerability disclosure program is evident. Privacy compliance is strong with comprehensive policies and GDPR adherence. Overall, while the business and content aspects are robust and professional, the security weaknesses related to SSL/TLS must be urgently addressed to ensure trust and secure user interactions. Strategic improvements in certificate management and enabling modern TLS protocols are recommended to elevate the security posture and overall website score.

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.

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

Neste operates in the energy and transportation sectors with a focus on renewable and circular solutions. Its competitive advantage lies in being the world’s leading producer of sustainable aviation fuel and renewable diesel, serving a global market with innovative products that reduce greenhouse gas emissions. The business model revolves around refining waste and residues into renewable fuels and raw materials for polymers and chemicals, targeting industries aiming for sustainability. The company maintains a strong partnership ecosystem and a clear growth strategy centered on climate action and circular economy principles. The website content and structure support a high level of professionalism and trust, reinforcing Neste's market leadership and commitment to sustainability.

Security posture

The website demonstrates a moderate security maturity level with well-configured security headers and HSTS policies. However, the absence of a valid SSL certificate and disabled TLS protocols represent critical vulnerabilities that expose users to potential risks such as data interception and man-in-the-middle attacks. The lack of OCSP stapling and session resumption further limits security and performance. No public security policy or incident response details are available, indicating a gap in transparency and readiness. Privacy compliance is well addressed, but the security posture requires immediate remediation of SSL/TLS issues to align with best practices and regulatory expectations.

Recommendations

  1. Renew and properly configure the SSL/TLS certificate to ensure valid HTTPS connections.
  2. Enable modern TLS protocols (TLS 1.2 and TLS 1.3) to enhance security and compatibility.
  3. Implement OCSP stapling and session resumption to improve certificate validation and performance.
  4. Publish a clear security policy and incident response plan to increase transparency and preparedness.
  5. Maintain and enhance privacy compliance measures, including regular audits and updates.
Technical notes

Notes

The website is built using React and Next.js frameworks, indicating a modern and scalable architecture. Hosting appears to be on Google Cloud infrastructure, providing reliability and global reach. The site includes comprehensive SEO meta tags, Open Graph tags, and accessibility features, contributing to good search engine visibility and user experience. Performance metrics are not explicitly provided but inferred to be moderate. The use of cookie consent tools and marketing optimization scripts shows attention to privacy and user engagement. However, the invalid SSL certificate and disabled TLS protocols represent significant technical debt and risk, requiring urgent attention to avoid undermining user trust and security.
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.
