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

3 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

      SSL Certificate Expires Soon

      SSL certificate expires in 11 days

      What to do: Renew SSL certificate before expiration

      • NIS2 21(2)(h)
      • IR 2024/2690 9.2(c): Implementing Regulation (EU) 2024/2690, Annex point 9.2(c): Cryptography
      • NIST SC-17: NIST SP 800-53 Rev. 5 SC-17: Public Key Infrastructure Certificates
    • 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

3M holds a strong market position as a diversified technology company with a century-plus history of innovation. Its business model focuses on manufacturing and supplying a wide range of products to various sectors, leveraging technology platforms and global expertise. Revenue streams are diversified across product categories and industries. The website indicates a broad partnership ecosystem and a commitment to sustainability and ethics. Target customers include industrial manufacturers, commercial enterprises, government agencies, and consumers. Growth indicators include active investor relations and ongoing product innovation announcements. The company operates globally with localized sites for many countries, reflecting a mature international footprint.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, cookie consent with opt-in mechanisms, and use of security-related scripts. However, no explicit security headers such as Content Security Policy or HSTS were detected in the provided data. There is no visible security.txt or vulnerability disclosure program, and no incident response contact information was found. The absence of exposed sensitive data and use of modern libraries reduce risk. Compliance with GDPR is indicated by cookie consent and privacy policy. Overall, the security maturity is good but could be improved by publishing explicit security policies and incident response contacts.

Recommendations

  1. Implement and publish explicit security headers including CSP, HSTS, and X-Frame-Options to enhance protection against common web attacks.
  2. Publish a dedicated security policy page and provide clear incident response contact channels such as security@ or abuse@ email addresses.
  3. Establish and publicize a vulnerability disclosure program and security.txt file to encourage responsible reporting of security issues.
  4. Enhance transparency around data retention policies and user privacy choices to strengthen GDPR compliance.
  5. Regularly audit third-party scripts and tracking tools to minimize privacy risks and improve site performance.

Technical notes

Notes

The website is built on IBM WebSphere Portal CMS and uses RequireJS for modular JavaScript loading, jQuery, and Tealium for tag management and analytics. Performance monitoring is done via Boomerang. The site is hosted likely on Akamai CDN infrastructure. The site is mobile-optimized with responsive design and accessibility features. SEO is supported by proper meta tags and structured navigation. The technical stack is modern and well-integrated, though some improvements could be made in security header implementation and reducing third-party script dependencies to optimize performance and security.
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.
