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

SIGMA GROUP a.s. is a well-established Czech company specializing in the research, development, and manufacturing of industrial pumps and pumping units. With a history dating back to 1868, it holds a leading market position as the largest manufacturer of pumping technology in the Czech Republic, serving clients in 76 countries. The company offers a broad portfolio of over 70 product lines and operates subsidiaries in Poland and other regions. The website reflects a professional and consistent brand image with detailed company history, certifications, and contact information. Technically, the website employs modern JavaScript libraries such as jQuery and Owl Carousel, uses Google Fonts, and integrates Google Analytics for user tracking. The site is mobile-optimized with good navigation and content quality. However, some technical improvements are recommended, including adding security headers and cookie consent mechanisms to enhance privacy compliance. From a security perspective, the site uses HTTPS and does not expose sensitive data or vulnerable libraries. The absence of WHOIS data reduces domain trustworthiness, but the overall business credibility and certifications support legitimacy. No incident response or vulnerability disclosure policies are published, indicating areas for improvement. Overall, the website presents a solid digital presence for an industrial manufacturing company, with moderate technical and security maturity. Strategic enhancements in privacy compliance and security posture would further strengthen 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

7 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.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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

    • 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. Security headers

    • 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

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

SIGMA GROUP a.s. operates in the energy and manufacturing sectors, focusing on industrial pumping technology. Its competitive advantage lies in its long-standing history, extensive product range, and international market reach. The business model centers on manufacturing and engineering with a global distribution network. Revenue streams likely derive from product sales, engineering services, and after-sales support. Target customers include industrial clients in energy, water management, agriculture, and petrochemical sectors. Growth indicators include recent projects and certifications. The company maintains a partnership ecosystem with subsidiaries and external collaborators such as SIGMA POLSKA and WDF (website developer). Strategic observations highlight the importance of maintaining certifications and expanding digital compliance to support market position.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enabled and no visible exposure of sensitive data. However, the lack of security headers such as Content Security Policy, HSTS, and X-Frame-Options reduces protection against common web attacks. No vulnerability disclosure or incident response information is available, which may hinder timely security issue reporting and resolution. GDPR compliance is partially addressed through a privacy policy, but the absence of a cookie consent mechanism is a gap. The use of Google Analytics introduces moderate user tracking, requiring transparent privacy practices. Overall, the security posture is adequate but would benefit from enhanced headers, documented incident response, and improved privacy controls.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, and X-Frame-Options to mitigate common web vulnerabilities.
  2. Add a cookie consent banner/mechanism to comply fully with GDPR and enhance user privacy transparency.
  3. Publish a vulnerability disclosure policy and incident response contact information to improve security readiness and trust.
  4. Enhance accessibility features to improve usability for all users and meet compliance standards.
  5. Regularly audit and update third-party libraries and tracking tools to minimize security risks and maintain performance.

Technical notes

Notes

The website uses a modern but relatively simple technology stack with jQuery 3.4.1 and Owl Carousel for UI components, Google Fonts for typography, and Google Analytics for tracking. The HTML structure is valid and includes meta tags for SEO and viewport settings for mobile responsiveness. Performance is moderate, with no major issues detected but potential for optimization. No CMS is detected, suggesting a custom or static site approach. Hosting provider details are not available. The site is mobile-optimized with good navigation clarity and consistent branding. Technical debt appears low but could be reduced further by adopting newer JavaScript frameworks and improving accessibility compliance.
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.
