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. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  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.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

The company operates primarily in manufacturing and transportation sectors, focusing on filtration solutions that address environmental and health challenges. Their business model is B2B, targeting industries requiring clean air, water, and mobility filtration. The website showcases awards and certifications, indicating strong market positioning and industry recognition. The digital infrastructure suggests investment in enterprise-grade CMS and analytics platforms, supporting global operations and compliance with privacy regulations such as GDPR. The absence of direct contact details on the main pages suggests a controlled communication strategy, possibly directing inquiries through specific channels not publicly listed. The company appears to maintain a strong partnership ecosystem and emphasizes sustainability and corporate responsibility.

Security posture

The website employs HTTPS with strong SSL configuration and includes multiple security headers enhancing protection against common web vulnerabilities. Cookie consent is managed via OneTrust, indicating GDPR compliance efforts. However, the lack of publicly available incident response contacts and vulnerability disclosure mechanisms limits transparency and may hinder rapid response to security incidents. No exposed sensitive data or vulnerable libraries were detected in the analysis. The security score is high but could be improved by publishing explicit security policies and contacts. Overall, the security posture is robust for a corporate website but lacks some transparency elements.

Recommendations

  1. Publish explicit incident response and security contact information on the website to improve transparency and readiness.
  2. Implement and publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  3. Enhance visibility of contact information, including verified company emails and phone numbers, to improve user trust and support.
  4. Regularly audit WHOIS data and ensure domain registration information is accurate and publicly accessible to avoid trust concerns.
  5. Continue to maintain and update privacy compliance mechanisms in line with evolving regulations such as GDPR and NIS2.

Technical notes

Notes

The website is built on Adobe Experience Manager, a robust enterprise CMS platform, ensuring scalability and content management efficiency. It uses Adobe Launch for tag management and Adobe Analytics for data insights, complemented by OneTrust for cookie consent and privacy compliance. The site is mobile-optimized with responsive design and accessibility features. Performance is moderate, likely influenced by the complexity of the CMS and tracking scripts. The technical stack is modern and appropriate for an enterprise, though opportunities exist to optimize loading times and enhance accessibility further. No deprecated or vulnerable libraries were detected, indicating good maintenance practices.
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.
