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

J.P. Sauer & Sohn Maschinenbau GmbH operates the website www.sauercompressors.com, providing high-pressure air and gas compressors for diverse sectors including industry, offshore, commercial shipping, and defence. The company positions itself as a leading global vendor with over 140 years of experience, offering multiple product lines and comprehensive service solutions. Their business model focuses on manufacturing, servicing, and rental of compressors, targeting industrial and governmental clients worldwide. Technically, the website employs modern JavaScript libraries such as jQuery, Slick Carousel, and Swiper.js, alongside Google Tag Manager for analytics. The site is mobile-optimized with good navigation and SEO practices, though it lacks explicit CMS identification. Performance is moderate, and accessibility is basic but functional. From a security perspective, the site uses HTTPS with no visible exposed sensitive data or vulnerable libraries. However, it lacks explicit security headers and a cookie consent mechanism, which are recommended for enhanced security and compliance. The absence of WHOIS data for the domain is notable and warrants further verification, though the website content and branding strongly indicate legitimacy. Overall, the site demonstrates a solid business presence with good technical implementation and moderate security posture. Strategic improvements in privacy compliance and security policies would enhance trust and regulatory adherence.

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

8 findings rated critical or high. Fix these first.

  1. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection
  2. 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';…
  3. GDPR outside view

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

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

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 · found on this site
  • 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 holds a strong market position in manufacturing high-pressure compressors with a global footprint supported by multiple subsidiary domains. Their competitive advantage lies in product reliability, extensive service offerings, and certifications such as ISO 9001, 14001, and 45001. Revenue streams likely include product sales, service contracts, spare parts, and rental solutions. Target customers are industrial sectors, offshore operators, commercial shipping, and defence organizations. Growth indicators include recent news about management changes and global partner networks. The partnership ecosystem is robust with dedicated country-specific domains, enhancing localized market penetration.

Security posture

The current security maturity is moderate with HTTPS enforced and no visible critical vulnerabilities. The lack of security headers and incident response information indicates room for improvement. GDPR compliance is partially addressed via privacy and terms pages, but cookie consent and data protection officer contacts are missing. No vulnerability disclosure or security.txt files are present, limiting transparency. The business impact of these gaps is moderate, primarily affecting regulatory compliance and user trust. Enhancing security policies and incident response readiness would strengthen the security culture and reduce risk exposure.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  2. Add a cookie consent banner/mechanism to comply with GDPR and other privacy regulations.
  3. Publish an explicit security policy and incident response contact information on the website.
  4. Create and maintain a vulnerability disclosure program or security.txt file to improve transparency.
  5. Provide data protection officer contact details to enhance GDPR compliance and user trust.

Technical notes

Notes

The website uses a modern JavaScript stack with libraries like jQuery 3.6.1, Slick Carousel, and Swiper.js, supporting interactive and responsive UI elements. Google Tag Manager is integrated for analytics and marketing. The site is custom-built or uses an unknown CMS, with clean HTML and meta tags supporting SEO. Performance is moderate, with video content optimized for desktop and removed on smaller screens. Accessibility is basic but present. There is an opportunity to improve technical SEO and accessibility standards further. Hosting details are not explicitly identified, and WHOIS data is missing, which could be a risk factor for domain management.
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.
