Sigma Energy & Marine AB is a Swedish-based engineering consulting company specializing in technology development across marine, renewable energy, subsea, process & plant, and industry simulations. The company serves international clients with complex projects and environmentally friendly solutions. It is part of the larger Sigma Group owned by Danir. The website is professionally designed, content-rich, and targets engineering professionals and companies seeking specialized consulting services. Technically, the site is built on WordPress with modern frontend libraries and includes Google Tag Manager for analytics. Security posture is good with HTTPS enabled and no visible vulnerabilities, but lacks some security headers and explicit privacy policies. WHOIS data for the domain is missing, which reduces domain trustworthiness from a registration perspective.

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

9 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

  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';…

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.

Breach exposure

Dark web exposure

Add-on

Leaked records that mention sigmaenergyandmarine.se, from OffSeq Breach.

No leaked records found

Breach holds no records for sigmaenergyandmarine.se right now. New leaks arrive continuously, so monitoring on Breach alerts you if that changes.

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 within its niche, leveraging a broad portfolio of engineering services in energy and marine sectors. Its business model focuses on consulting and project delivery for international clients. The presence of multiple subsidiaries and partner domains under the Sigma Group umbrella indicates a well-established partnership ecosystem. The company emphasizes career development and corporate social responsibility, enhancing its employer brand. The website content and structure support clear communication of services and career opportunities, indicating a mature digital presence.

Security posture

The website demonstrates a moderate to good security maturity level with HTTPS enforced and no exposed sensitive data. However, the absence of key security headers such as Content-Security-Policy and lack of explicit security or incident response policies are gaps. No vulnerability disclosure or security.txt files were found. Privacy compliance is basic with a cookie consent banner but no clear privacy policy page. The missing WHOIS data for the domain is a concern for domain legitimacy. Overall, the security posture is adequate but could be improved with enhanced headers, documented policies, and better privacy disclosures.

Recommendations

  1. Implement comprehensive privacy and cookie policies accessible from the website footer or header.
  2. Add security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to improve protection against common web attacks.
  3. Publish a security policy and incident response contact information to improve transparency and readiness.
  4. Regularly audit and update third-party scripts and libraries to mitigate vulnerabilities.
  5. Investigate and correct WHOIS data inconsistencies to improve domain trustworthiness.

Technical notes

Notes

The website uses WordPress CMS with a modern frontend stack including jQuery, Slick Slider, and Google Tag Manager. The site is mobile optimized with responsive design and good navigation clarity. Performance is moderate with lazy loading implemented for images and videos. SEO is supported by Yoast SEO plugin with proper meta tags and structured data in JSON-LD format. Accessibility is basic but could be improved. Hosting provider details are not explicitly identified. Overall, the technical infrastructure supports a professional and functional web presence with room for optimization in performance and accessibility.
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.
