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. 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

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 holds a leading position in the technology consulting sector, offering a broad range of services including consulting, delivery methods, and partner assignments. Their business model centers on leveraging technological know-how to drive client competitiveness. The company targets businesses requiring advanced technological solutions and consulting services. Ownership by Danir AB and multiple subsidiaries indicate a diversified and robust corporate structure. The website content and linked domains confirm a wide geographic and sectoral reach. Marketing and analytics integrations suggest active customer engagement and growth focus. The absence of explicit terms of service or security policy pages is a minor gap in transparency. Overall, Sigma Group demonstrates strong market positioning and operational maturity.

Security posture

The website enforces HTTPS and uses secure forms for data collection, such as CV registration. Multiple third-party analytics and tracking scripts are present, which increases the attack surface but no vulnerable libraries or exposed sensitive data were detected in the HTML content. Security headers are not explicitly detected and should be implemented to enhance protection against common web attacks. No incident response or security policy pages were found, which could improve transparency and readiness. The cookie consent mechanism is implemented, supporting GDPR compliance. Overall, the security posture is good but could be enhanced with additional headers and explicit security documentation.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options.
  2. Publish explicit security policy and incident response pages to improve transparency and preparedness.
  3. Add a security.txt file to facilitate vulnerability disclosure and improve security communication.
  4. Enhance accessibility features to meet higher compliance standards.
  5. Regularly audit and update third-party scripts to mitigate potential vulnerabilities.

Technical notes

Notes

The website uses a modern tech stack including Vue.js for frontend interactivity and Axios for data fetching. It integrates multiple analytics and marketing tools such as Google Analytics, TikTok Pixel, LinkedIn Insight Tag, Facebook Pixel, and Snap Pixel. The site is mobile optimized with responsive design and good SEO practices including meta tags and Open Graph data. Performance is moderate, with some heavy media content like videos and images. No CMS is explicitly detected, suggesting a custom or proprietary platform. Hosting provider details are not available from the content. Overall, the technical infrastructure supports a professional and scalable web presence with room for performance optimization.
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.
