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

2 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

  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

ASML operates in the high-technology sector, focusing on semiconductor lithography equipment. Its competitive advantage lies in its advanced technology and innovation leadership in EUV lithography. The business model centers on supplying cutting-edge equipment and support services to semiconductor manufacturers worldwide. Revenue streams include product sales, refurbished systems, and customer support services. The target customers are major chipmakers and semiconductor fabs. The company has a global footprint with multiple locations and a strong investor relations presence. Partnerships and collaborations, such as with imec, indicate a strategic ecosystem approach. The website content and structure support a transparent and investor-friendly communication strategy.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, use of cookie consent tools, and no visible exposure of sensitive information. Security headers are implied but not explicitly visible in the HTML content. No security or incident response policies are published, which is a gap in transparency. No vulnerabilities or outdated libraries were detected in the provided content. The site uses reputable third-party scripts and analytics tools. Overall, the security maturity is high but could be improved by publishing formal security policies and incident response contacts.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Provide clear incident response contact channels such as security@ or abuse@ email addresses.
  3. Implement and publish a vulnerability disclosure policy or security.txt file.
  4. Enhance visible security headers and document them for transparency.
  5. Continue to maintain and update privacy compliance mechanisms and cookie consent.

Technical notes

Notes

The website is built using modern web technologies including React and Next.js frameworks, supported by Sitecore CMS for content management. It integrates Adobe Dynamic Tag Management for marketing and analytics, and OneTrust for cookie consent management. The site is well-optimized for performance and mobile devices, with responsive design and accessibility considerations. The use of structured data (JSON-LD) enhances SEO and content discoverability. No technical debt or legacy technologies were detected. The infrastructure appears robust and scalable, suitable for an enterprise-level corporate website.
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.
