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

MANN+HUMMEL is a global leader in filtration technology, specializing in air and water filtration solutions since 1941. The company targets industrial sectors including automotive, environmental, and life sciences, providing innovative filtration products and services. Their website reflects a mature digital presence with comprehensive corporate information and product offerings, primarily in Czech language for the regional audience. The site is built on Adobe Experience Manager, indicating a robust technical infrastructure with modern content management and analytics capabilities. Security posture is strong with HTTPS, security headers, and cookie consent mechanisms in place, though explicit security policies and incident response contacts are not publicly available. The absence of WHOIS data for the domain is a notable anomaly that slightly reduces trustworthiness but does not detract from the professional presentation and established market position. Overall, the website is well-designed, accessible, and compliant with GDPR, supporting the company's credibility and business operations.

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

4 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. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • High

      Third-party services without privacy policy

      Detected services: Facebook, LinkedIn, YouTube

      What to do: Document all third-party data sharing in your privacy policy

  3. 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

MANN+HUMMEL operates as an essential manufacturing entity in the filtration sector, with a long-standing history and global market leadership. Their business model focuses on B2B relationships, supplying filtration solutions to automotive and environmental industries. The website's content and navigation are tailored to industrial clients and stakeholders, emphasizing corporate responsibility, innovation, and sustainability. The company leverages Adobe's digital marketing and analytics tools to optimize user engagement and compliance. Despite the lack of visible direct contact details, the site provides extensive corporate and product information, supporting informed decision-making by customers and partners. The missing WHOIS data suggests either privacy protection or registry issues, warranting further verification for critical business partnerships.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, comprehensive security headers including CSP, and a GDPR-compliant cookie consent mechanism. No vulnerabilities or exposed sensitive data were detected in the analysis. However, the absence of a dedicated security policy or incident response contact reduces transparency in security governance. There is no evidence of a vulnerability disclosure program or security.txt file, which are recommended best practices for corporate websites. Overall, the security measures in place are strong but could be enhanced by publishing explicit security policies and contact channels for incident reporting.

Recommendations

  1. Publish a dedicated security policy and incident response page to improve transparency and trust.
  2. Add explicit contact information for security incidents, such as a security@ or abuse@ email address.
  3. Implement and publicize a vulnerability disclosure program or security.txt file.
  4. Verify and update WHOIS domain registration data to ensure consistency and trustworthiness.
  5. Consider adding a terms of service page to clarify legal terms and user agreements.

Technical notes

The site uses modern HTML5, CSS, and JavaScript with deferred script loading for performance optimization. Cookie consent is managed by OneTrust, ensuring GDPR compliance.

No hosting provider details were identified from the content. The technical stack reflects a well-maintained enterprise-grade digital platform suitable for a global manufacturing company.
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.
