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

Sauer Compressors USA is a specialized manufacturer focused on engineering and producing high-pressure air and gas compressors, offering a lifetime warranty on their products. The company targets industrial clients requiring reliable and high-performance compressor solutions. The website is built on WordPress, leveraging modern web technologies such as Bootstrap, jQuery, and Font Awesome, and integrates analytics and marketing tools including Google Analytics, Microsoft Clarity, and Cookiebot for privacy compliance. The site demonstrates good design quality, mobile optimization, and SEO practices, providing a professional user experience. However, the absence of WHOIS registration data raises concerns about domain legitimacy, despite the professional presentation and active content. Security posture is generally good with HTTPS and cookie consent mechanisms, but lacks explicit security headers and published security policies. Privacy compliance is partially met with cookie consent but lacks a clear privacy policy page. Contact information is not readily available, which may impact business credibility. Overall, the website is functional and professional but would benefit from improved transparency in domain registration, privacy policies, and security disclosures.

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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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';…

  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 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

The company operates in the manufacturing sector, specializing in high-pressure compressor technology. Its business model centers on engineering and manufacturing with a focus on product reliability and customer assurance through lifetime warranties. The target market includes industrial and commercial sectors requiring specialized compressor equipment. The website's integration of marketing and analytics tools indicates an active digital marketing strategy. However, the lack of visible contact details and privacy policy may limit trust and customer engagement. The absence of WHOIS data is unusual and may warrant further verification. No partnerships or subsidiaries are explicitly identified from the website content.

Security posture

The website employs HTTPS, ensuring encrypted communication, and implements a cookie consent mechanism aligned with GDPR requirements. It uses reputable analytics and marketing services, but no advanced security headers were detected, which could enhance protection against common web vulnerabilities. There is no evidence of a published security policy or incident response contact, which are important for transparency and compliance. No vulnerabilities or exposed sensitive data were identified in the content. The security posture is moderate but could be improved by adding security headers, publishing security policies, and providing incident response contacts.

Recommendations

  1. Register the domain properly and ensure WHOIS data is publicly available or justified if privacy protected.
  2. Publish a comprehensive privacy policy page accessible from the website footer or main navigation.
  3. Implement and verify security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Add clear contact information including company emails and phone numbers to improve business credibility.
  5. Consider publishing a security policy and incident response contact information to enhance trust and compliance.

Technical notes

Notes

The website is built on WordPress CMS using Bootstrap framework and common JavaScript libraries like jQuery. It integrates multiple third-party services including Google Tag Manager, Microsoft Clarity, and Cookiebot for analytics and privacy compliance. The site loads external resources from reputable CDNs and uses modern CSS and responsive design techniques. Performance is moderate with no major issues detected. Accessibility features are basic but present. SEO is supported by Yoast SEO plugin and proper meta tags including Open Graph and JSON-LD structured data. Technical risks include missing security headers and potential reliance on multiple third-party scripts which could impact privacy and performance.
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.
