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 strong market position as a leading consulting group with a focus on technology-driven solutions. Their business model revolves around providing consulting services and technological expertise to enhance customer competitiveness. The company targets businesses requiring advanced technological consulting and innovation support. Their extensive subsidiary network and ownership by Danir AB indicate a robust partnership ecosystem and strategic growth. The website content and linked domains confirm a diversified portfolio and active engagement in innovation races and expert development programs, signaling growth and market expansion. The presence of multiple social media channels and news updates further supports their active market engagement and brand visibility.

Security posture

The website enforces HTTPS and employs secure form submissions, indicating a baseline security maturity. Multiple third-party analytics and marketing scripts are integrated, which increases the attack surface but are common in enterprise environments. No explicit security headers like CSP or X-Frame-Options were detected, which could be improved to mitigate certain web attacks. There is no visible security.txt or vulnerability disclosure page, and no incident response contact information is provided, which are gaps in transparency and readiness. No exposed sensitive data or vulnerable libraries were found in the HTML content. Overall, the security posture is good but could benefit from enhanced header policies and published security practices.

Recommendations

  1. Implement and enforce security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen web security.
  2. Publish an incident response policy and provide clear contact channels for security incidents to improve transparency and readiness.
  3. Create and maintain a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  4. Regularly audit and update third-party scripts to minimize risks from external dependencies.
  5. Enhance data protection officer visibility and provide explicit contact information to align with GDPR best practices.

Technical notes

Notes

The website is built using modern web technologies including Vue.js for reactive components and Axios for asynchronous data fetching. It integrates multiple analytics and marketing tools such as Google Analytics, TikTok Pixel, Facebook Pixel, LinkedIn Insight, and Snap Pixel, indicating a sophisticated tracking and marketing infrastructure. The site is mobile-optimized with responsive design and good accessibility features. Performance is moderate, likely influenced by the number of external scripts. The site lacks explicit CMS identification but appears custom-built or heavily customized. Hosting provider details are not directly discernible. Overall, the technical infrastructure supports a professional and scalable web presence with opportunities for performance optimization and enhanced security configurations.
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.
