Security score

75/100

Risk levelMedium

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

PQ Corporation is a medium-sized, established global manufacturer specializing in silicates, silicas, and derivative chemical products. The company serves diverse industrial sectors including paints & coatings, purification, chemical manufacturing, construction, personal care, and food & beverage. Their products contribute to sustainability and safety, positioning PQ as a leader in performance chemicals. The website reflects a mature digital presence built on WordPress with modern technologies and strong SEO practices. Security posture is good with HTTPS and form protections, though some security headers and incident response disclosures are absent. The absence of WHOIS data is a minor concern but does not detract significantly from the overall legitimacy. PQ demonstrates a commitment to corporate responsibility and innovation, supported by recent acquisitions and industry awards.

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. GDPR outside view

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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  2. 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

PQ Corporation holds a strong market position as a leading global supplier of specialty silicates and silicas, leveraging a B2B business model focused on industrial and consumer product applications. Their growth is evidenced by acquisitions and facility expansions. The company targets industrial manufacturers and formulators requiring environmentally friendly chemical ingredients. PQ's partnership ecosystem includes industry leaders like BASF and Nouryon. The company emphasizes sustainability and safety as core values, aligning with regulatory compliance across multiple countries. Their digital presence supports global outreach with multilingual support and a dedicated careers portal, indicating ongoing talent development and international footprint.

Security posture

The website employs HTTPS with good SSL configuration and uses Gravity Forms with anti-spam tokens to secure user input. However, no explicit security headers such as Content-Security-Policy or X-Frame-Options were detected, which could enhance protection against common web attacks. There is no public incident response or vulnerability disclosure page, limiting transparency in security management. The site shows no signs of vulnerabilities or exposed sensitive data. Overall, the security posture is solid but could be improved with additional headers and published security policies.

Recommendations

  1. Implement and configure security headers like Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to enhance web security.
  2. Publish an incident response plan or security contact page to improve transparency and readiness.
  3. Add a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  4. Consider integrating a cookie consent mechanism to comply fully with privacy regulations.
  5. Regularly audit third-party scripts and plugins to ensure no vulnerable libraries are in use.

Technical notes

Notes

The website is built on WordPress CMS with a modern tech stack including jQuery, GSAP, Swiper.js, and Google Tag Manager for analytics. It uses Gravity Forms for data collection with anti-spam measures. The site is well-optimized for performance and mobile responsiveness, with comprehensive SEO metadata and structured data (JSON-LD) for enhanced search engine visibility. Multilingual support is implemented via TranslatePress. No hosting provider information was directly detected. The site demonstrates good technical maturity with room for security enhancements and potential hosting transparency improvements.
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.
