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

3 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"

  2. 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
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

Helexia operates in the energy sector with a focus on sustainable energy transition for companies. Their business model revolves around consultancy, implementation of energy-saving solutions, and ongoing services such as monitoring and maintenance. The company targets medium to large enterprises in Belgium, leveraging partnerships and client references to strengthen market position. The website showcases a variety of service offerings and resources including blogs, FAQs, e-books, and webinars, indicating an active content marketing strategy. The presence of partner logos and client references enhances credibility. The company appears to be well-established with a consistent brand and professional digital footprint.

Security posture

The website enforces HTTPS and uses cookie consent banners compliant with GDPR, reflecting awareness of privacy and security regulations. However, no explicit security policy or incident response information is found, which could be improved to enhance transparency and readiness. The site uses multiple third-party scripts including HubSpot and LinkedIn tracking pixels, which increases the attack surface and requires regular security audits. No critical vulnerabilities or exposed sensitive data were detected in the analysis. Security headers are not explicitly present, suggesting an opportunity to strengthen defenses against common web attacks. Overall, the security posture is good but could benefit from additional hardening and documentation.

Recommendations

  1. Implement comprehensive security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to mitigate common web vulnerabilities.
  2. Publish a dedicated security policy and incident response page to improve transparency and user trust.
  3. Add a security.txt file to facilitate responsible vulnerability disclosure and improve security communication.
  4. Enhance accessibility features to comply with best practices and improve user experience for all visitors.
  5. Regularly review and update third-party scripts and plugins to minimize security risks and maintain compliance.

Notes

The website is built on a modern WordPress platform using Elementor for page building and Yoast SEO for search optimization. It integrates several plugins for enhanced functionality including JetMenu, JetEngine, PowerPack Elements, and Complianz GDPR for cookie management. The site loads multiple external scripts for analytics and marketing, primarily from HubSpot and LinkedIn. Performance is moderate with good mobile optimization and basic accessibility features. The site uses structured data (JSON-LD) for SEO and social media integration. Hosting provider details are not explicitly found. Overall, the technical infrastructure supports a professional and functional website but could be optimized further for speed and security.
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.
