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

Siemens Portugal operates as an essential entity within the technology sector, serving industrial, infrastructure, and mobility markets. Its business model revolves around providing integrated technology solutions that combine real and digital worlds to enhance efficiency and sustainability. The company maintains a strong market position as a leader in Portugal, supported by a global parent company Siemens AG. The website's content and linked resources indicate a well-established partnership ecosystem and a focus on digital transformation services. The absence of direct contact emails or phone numbers on the main site suggests a controlled communication channel via contact forms, typical for large enterprises. The presence of whistleblowing and compliance documents further reinforces corporate governance standards.

Security posture

The website employs HTTPS with a good SSL configuration and uses a consent management platform to handle privacy and cookie compliance. Security headers are minimal, with only Cache-Control detected, suggesting room for improvement by adding headers like Content-Security-Policy and X-Frame-Options. No exposed sensitive data or vulnerable libraries were found in the HTML content. The lack of a public security policy or incident response contact information is a gap in transparency and readiness communication. No vulnerability disclosure program or security.txt file is present, which could enhance trust and security culture. Overall, the security posture is solid but could benefit from enhanced security headers and explicit security governance documentation.

Recommendations

  1. Implement and publish a dedicated security policy page outlining security practices and compliance frameworks.
  2. Add comprehensive security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to improve protection against common web attacks.
  3. Provide clear incident response contact channels, including security@ or abuse@ email addresses, to facilitate vulnerability reporting and incident management.
  4. Establish a vulnerability disclosure program and publish a security.txt file to promote transparency and responsible disclosure.
  5. Enhance form security by integrating CAPTCHA or other anti-bot mechanisms to prevent automated abuse.

Technical notes

Notes

The website is built using modern web technologies including Vue.js for frontend components and Brightcove for video delivery. It leverages Adobe Experience Manager as the CMS platform, indicated by the presence of Adobe DTM and OTE scripts. Analytics are handled via Matomo and Adobe Analytics, with marketing automation through Eloqua. The site is mobile optimized with responsive design and accessibility features such as skip links and ARIA labels. Performance is moderate, with multiple CSS and JS assets loaded asynchronously or via module preload. The site uses a consent management platform (Usercentrics) to comply with privacy regulations. Overall, the technical infrastructure is robust and supports a high-quality user experience with opportunities for further optimization in security headers and performance tuning.
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.
