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 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

  3. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

SES operates in the energy sector with a focus on electricity distribution and renewable energy production. Its business model centers on serving a defined regional market with tailored services for private and business customers, municipalities, and energy producers. The company leverages certifications and CSR reporting to build trust and demonstrate sustainability commitments. SES's digital ecosystem includes dedicated portals for customers and municipalities, indicating a mature service-oriented approach. The presence of multiple contact points and comprehensive legal and privacy documentation supports strong business credibility. SES's partnerships and related domains suggest a well-integrated regional network. Growth indicators include ongoing investments in photovoltaic capacity and electric mobility services.

Security posture

SES exhibits a strong security posture evidenced by ISO/IEC 27001:2022 certification and the implementation of HTTPS with appropriate security headers. The website does not expose sensitive information and employs a cookie consent mechanism aligned with GDPR requirements. The use of Matomo analytics reflects a privacy-conscious approach to user tracking. However, the absence of explicit incident response contacts and vulnerability disclosure policies represents a gap in transparency and readiness. No known vulnerabilities or outdated libraries were detected in the provided content. Overall, SES maintains a secure environment appropriate for its business scale and sector, but could improve by formalizing incident response and disclosure practices.

Recommendations

  1. Publish explicit incident response contact information on the website to improve transparency and readiness.
  2. Implement and publicize a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  3. Enhance website accessibility features to meet higher compliance standards and improve user experience for all visitors.
  4. Regularly audit and update third-party libraries and scripts to mitigate potential security risks.
  5. Consider publishing Data Protection Officer contact details to strengthen GDPR compliance and user trust.

Technical notes

Notes

The website is built on a custom or proprietary CMS platform using standard web technologies such as HTML5, CSS, and JavaScript with jQuery 3.7.1. It integrates Matomo for analytics, which is a privacy-friendly alternative to mainstream trackers. The site is responsive and optimized for mobile devices, with good SEO practices including meta tags and Open Graph data. Performance is moderate, with some large images in the banner slider that could be optimized further. The site uses multiple JavaScript modules for UI interactions and form handling. No common CMS like WordPress or Joomla was detected, indicating a bespoke solution. Hosting provider details are not explicitly available from the content. Overall, the technical infrastructure supports a professional and functional user experience 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.
