  3. (c) Business continuity, backups and crisis management: Not visible from outside
  4. (d) Supply chain security: Not visible from outside

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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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';…

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

  • SSL/TLS: did not complete in this scan.
  • Email security: did not complete in this scan.
  • DNS health: did not complete in this scan.
  • Network security: did not complete in this scan.
  • 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

Koppers operates in essential infrastructure sectors with a B2B business model focused on manufacturing and services. Their competitive advantage lies in sustainability-driven innovation and a broad product portfolio. The company targets infrastructure industries globally, supported by investor relations and community engagement initiatives. Growth indicators include recent annual reports and news releases highlighting expansion and leadership recognition. The partnership ecosystem includes investor relations and sustainability reporting platforms. Strategic observations suggest a mature enterprise with a focus on long-term sustainability and market leadership.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, comprehensive security headers, and no visible sensitive data exposure. However, the absence of a published privacy policy, terms of service, and vulnerability disclosure reduces compliance maturity. Incident response readiness is unclear due to lack of explicit contact channels. Data protection practices are partially implemented via cookie consent mechanisms. Overall, the security culture appears professional but could benefit from enhanced transparency and formalized policies.

Recommendations

  1. Publish a comprehensive privacy policy detailing data handling and GDPR compliance.
  2. Add terms of service and security policy pages to improve legal transparency.
  3. Implement and publish a vulnerability disclosure or security.txt file to encourage responsible reporting.
  4. Provide clear incident response contact information, including security or abuse emails.
  5. Enhance accessibility features to meet compliance standards and improve user experience.

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.
