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

Sigma Embedded Engineering AB is a Swedish technology consulting company specializing in embedded engineering, product development, electrification, AI, digitalization, and connectivity solutions. As part of the larger Sigma Group, it benefits from a strong market position with a medium-sized workforce and a broad service offering targeting technology professionals and clients in energy and transport sectors. The website reflects a professional and consistent brand image with clear contact information and active recruitment efforts. Technically, the website is built on WordPress with modern plugins and tools such as Yoast SEO, Google Analytics, and Google Tag Manager. It is hosted by Loopia AB, a reputable registrar and hosting provider. The site is mobile optimized and performs moderately well, with good SEO practices implemented. However, some improvements could be made in accessibility and security headers. From a security perspective, the site uses HTTPS with a good SSL configuration but lacks DNSSEC and important security headers. There is no visible privacy policy or incident response information, which are gaps in compliance and security transparency. Cookie consent is implemented properly, indicating some attention to privacy compliance. Overall, the website is trustworthy and professional but would benefit from enhanced privacy and security disclosures to improve compliance and user trust. Strategic recommendations include adding a privacy policy, enabling DNSSEC, publishing security policies, and implementing security headers.

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

10 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

  2. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  3. 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';…

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 Embedded Engineering operates within the technology consulting sector, focusing on embedded systems and related advanced technologies. Its competitive advantage lies in its integration within the Sigma Group, providing access to a broad network and resources. The business model centers on delivering R&D and engineering services to clients in electrification, AI, and connectivity, with a strong emphasis on recruitment and talent development. The company targets engineers and technology firms seeking specialized embedded engineering solutions. Growth indicators include active job postings and a visible employer branding strategy. The partnership ecosystem includes multiple Sigma Group subsidiaries, enhancing market reach and service breadth.

Security posture

The website demonstrates a moderate to good security posture with HTTPS enforced and no visible sensitive data exposure. However, the absence of DNSSEC and security headers such as Content-Security-Policy and X-Frame-Options reduces its defense-in-depth. There is no published security policy or incident response contact, which limits transparency and readiness perception. Privacy compliance is partial, with a cookie consent banner but no privacy policy page. The site uses modern technologies without known vulnerable libraries. Overall, the security maturity is adequate but could be improved to meet higher compliance and trust standards.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Publish a comprehensive privacy policy detailing data handling and GDPR compliance.
  3. Add security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  4. Create and publish a security policy and incident response contact information to improve transparency.
  5. Regularly audit and update third-party scripts and plugins to avoid vulnerabilities.

Technical notes

Notes

The website is built on WordPress CMS with a modern tech stack including Yoast SEO, jQuery, and Google Analytics integration. It uses Slick Slider for UI components and Material Icons for design consistency. Hosting is provided by Loopia AB, a reputable Swedish registrar and hosting provider. Performance is moderate with some optimization via WP Rocket caching. The site is mobile responsive and SEO optimized with proper meta tags and structured data (JSON-LD). Accessibility features are basic and could be enhanced. No critical technical debt or outdated technologies were detected, but security headers are missing which is a technical risk.
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.
