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

Atmus Filtration Technologies Inc. is a large manufacturing company specializing in filtration solutions for diverse global markets including transportation, agriculture, construction, mining, marine, and power generation. The company emphasizes innovation, sustainability, and aftermarket support, leveraging a 60-year industry heritage and strong OEM partnerships. Their digital presence is built on Drupal CMS with modern web technologies and includes active social media engagement and recent corporate news updates. The website is well-designed, mobile-optimized, and provides a good user experience with clear navigation and relevant content. Security posture is strong with HTTPS and cookie consent mechanisms, though explicit security headers and policies could be improved.

Overall, the website reflects a credible and established business with room for enhanced transparency and security documentation.

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. 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
    • 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

Atmus operates in the manufacturing sector with a focus on filtration technologies, serving industrial customers and OEMs worldwide. Their business model is B2B, offering a broad product portfolio and aftermarket services. The company positions itself as a leader with a strong brand (Fleetguard) and a commitment to sustainability. Recent leadership appointments and sustainability reporting indicate active corporate governance and growth. The website links to partner and investor domains, reinforcing business legitimacy. Marketing and analytics tools are used moderately, with Google Tag Manager and OneTrust for consent management. The company targets industrial sectors such as transportation, energy, and manufacturing, with a large operational scale.

Security posture

The website enforces HTTPS and implements cookie consent via OneTrust, indicating attention to user privacy and security. However, explicit security headers like X-Frame-Options and X-Content-Type-Options are not evident in the HTML content. No security policy, incident response information, or vulnerability disclosure mechanisms are published, which are recommended for corporate transparency and compliance. No exposed sensitive data or vulnerable libraries were detected. The security posture is good but could be enhanced by publishing formal security documentation and adding missing headers.

Recommendations

  1. Publish a comprehensive privacy policy and make it easily accessible on the website.
  2. Add explicit security headers such as X-Frame-Options, X-Content-Type-Options, and Content-Security-Policy.
  3. Provide a security policy and incident response contact information to improve transparency.
  4. Implement and publish a vulnerability disclosure policy or security.txt file.
  5. Clarify domain registration details and ensure WHOIS information is accurate and publicly available.

Technical notes

Notes

The website is built on Drupal 10 CMS, using modern JavaScript libraries and Google Tag Manager for analytics. It employs OneTrust for cookie consent management, ensuring compliance with privacy regulations. The site is mobile-optimized and accessible, with good SEO practices including meta tags and Open Graph data. Performance is moderate, with no major issues detected. The absence of hosting provider information and domain registration data is a technical gap. Overall, the infrastructure is modern and well-maintained but could benefit from enhanced security header implementation and domain registration transparency.
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.
