Security score

79/100

Risk levelLow

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

NCH Corporation is a well-established global company specializing in industrial water treatment, energy conservation, and maintenance solutions. Founded in 1919, it has a strong family leadership legacy and distributes products to over 50 countries. The website reflects a mature business with a broad product portfolio targeting industrial and institutional customers. Technically, the site is built on ASP.NET WebForms with DNN CMS, using legacy JavaScript libraries and standard SEO and accessibility features. Security posture is good with HTTPS and cookie consent implemented, though security headers and incident response policies are not publicly visible. The absence of WHOIS data for the queried domain limits domain registration trust analysis but does not detract from the overall legitimacy indicated by the website content and social media presence. Strategic recommendations include updating technical components, enhancing security headers, and publishing explicit security policies to improve trust and compliance.

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

1 finding 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.

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

NCH Corporation operates in the energy and manufacturing sectors, providing chemical and maintenance products globally. Its business model is B2B manufacturing and distribution with a strong emphasis on sustainability and operational efficiency. The company leverages a family-led leadership structure and maintains a global footprint. The website targets industrial clients and professionals seeking maintenance and conservation solutions. The company’s digital presence includes social media engagement and privacy compliance, indicating a mature marketing approach. Growth potential is supported by a diverse product range and international reach. No direct contact details are provided on the main site, which may limit immediate customer engagement but aligns with a corporate B2B focus.

Security posture

The website enforces HTTPS and includes a cookie consent mechanism, reflecting compliance with privacy regulations. However, it lacks visible security headers such as Content Security Policy or HSTS, which are recommended for enhanced protection. The use of older JavaScript libraries like jQuery 1.12.4 may expose the site to known vulnerabilities if not regularly patched. No incident response or vulnerability disclosure information is publicly available, which could be improved to demonstrate security maturity. No exposed sensitive data or obvious vulnerabilities were detected in the HTML content. Overall, the security posture is solid but could benefit from modern best practices and transparency.

Recommendations

  1. Implement and enforce security headers including CSP, HSTS, X-Frame-Options, and X-XSS-Protection.
  2. Upgrade JavaScript libraries to current secure versions to mitigate known vulnerabilities.
  3. Publish explicit security policies and incident response contact information on the website.
  4. Add a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Enhance accessibility features and mobile responsiveness to improve user experience and compliance.

Technical notes

Notes

The website is built on a mature ASP.NET WebForms framework with DNN CMS, indicating a stable but somewhat dated technology stack. It uses jQuery 1.12.4 and jQuery UI 1.12.1, which are older versions that may require updates for security and performance. The site loads multiple external scripts including Google Tag Manager and Font Awesome 4.1.0. Performance is moderate with basic mobile optimization and accessibility features. SEO is basic but present with meta tags and structured navigation. The hosting environment is not explicitly identified but likely Windows-based given the technology stack. Opportunities exist to modernize the front-end stack, improve performance, and enhance security configurations.
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.
