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. 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 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

    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 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.

Business context

Business profile

SEFE operates in the energy sector with a focus on European markets, providing diversified energy sources and services including gas, LNG, power, hydrogen, and carbon management. Their business model revolves around integrated portfolio management, infrastructure operation, and customer-centric energy solutions. The company targets industrial clients, municipal utilities, and energy providers, emphasizing resilience and sustainability. Their market position is that of an important European energy provider with strategic partnerships and investments in future energy technologies. The website's content and structure suggest a medium-sized enterprise with a clear growth and transformation agenda. The presence of ISO 27001 certification and professional branding supports their credibility. Their digital ecosystem includes LinkedIn for corporate communications and Usercentrics for privacy compliance, indicating a well-managed online presence.

Security posture

The website demonstrates a good security posture with mandatory HTTPS usage and integration of a consent management platform to comply with GDPR. The absence of exposed sensitive data and use of modern JavaScript frameworks reduce attack surface. However, explicit security headers like X-Frame-Options and X-Content-Type-Options are not evident in the HTML, which could be improved. No security.txt or incident response contacts were found, which are recommended best practices for vulnerability disclosure and incident handling. The WHOIS privacy protection is justified for a corporate entity but limits transparency. Overall, the security maturity is solid but could benefit from enhanced header policies and published security policies.

Recommendations

  1. Implement and explicitly configure security headers such as X-Frame-Options and X-Content-Type-Options to enhance protection against clickjacking and MIME sniffing.
  2. Publish a security policy page and provide incident response contact information to improve transparency and facilitate vulnerability reporting.
  3. Regularly audit third-party scripts and libraries for vulnerabilities and update them to latest secure versions.
  4. Enhance SEO by adding structured data (JSON-LD) for organization and breadcrumb schema to improve search engine understanding.
  5. Consider adding a security.txt file at the root domain to formalize vulnerability disclosure process.

Notes

The website is built with modern web standards including HTML5, CSS3, and ES6 JavaScript modules. It uses jQuery 3.6.0 and several jQuery plugins for UI enhancements and file uploads. The Usercentrics CMP integration ensures GDPR-compliant cookie consent management. Google Tag Manager is used for analytics and marketing tracking. The site is mobile optimized with responsive design and good accessibility features. Performance is moderate with multiple video assets and animations, which may impact load times but enhance user experience. No CMS or hosting provider information is directly detectable from the HTML. The site structure is clear and navigation is intuitive, supporting a positive user experience.
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.
