Medium risk. 4 critical or high findings in Security headers and SSL/TLS.

Security score

71/100

Risk levelMedium

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

Verdo is an energy solutions company specializing in sustainable energy production, energy savings, and bioenergy fuel sales. The website presents a professional and consistent brand image targeting general and business audiences interested in sustainable energy. The technical infrastructure includes modern analytics and marketing tools such as Google Analytics, Microsoft Clarity, and LinkedIn marketing integrations, supported by a cookie consent mechanism that complies with GDPR principles. However, the absence of WHOIS registration data raises concerns about domain legitimacy, although the website content and branding mitigate some risk. Security posture is moderate with room for improvement in security headers and published security policies. Overall, the website is functional and professional but requires enhanced transparency and security practices to improve trust and compliance.

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 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';…

  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

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

Verdo operates in the energy sector with a focus on sustainability and bioenergy. The company targets customers interested in energy efficiency and renewable energy solutions. The business model revolves around providing energy savings services, sustainable energy production, and bioenergy fuel sales. The website integrates multiple marketing and analytics platforms, indicating a data-driven approach to customer engagement. The lack of visible privacy and terms of service pages suggests an area for compliance improvement. The company appears to be medium-sized based on website sophistication and contact information. No parent or subsidiary companies are identified from the data.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enabled and a cookie consent mechanism in place. However, no explicit security headers were detected, and no published security or incident response policies were found. The use of multiple third-party trackers increases the attack surface and requires careful management of data privacy. The absence of WHOIS data is a notable concern for domain legitimacy and trust. There is no evidence of vulnerability disclosure or security.txt files, which are recommended for transparency and incident management. Overall, the security posture is adequate but could be significantly improved with better header configurations, published policies, and domain registration transparency.

Recommendations

  1. Implement and verify HTTP security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish clear and accessible privacy policy and terms of service pages to improve legal compliance and user trust.
  3. Obtain and ensure public availability of WHOIS domain registration data to enhance domain legitimacy and trustworthiness.
  4. Establish and publish a vulnerability disclosure policy or security.txt file to facilitate responsible security reporting.
  5. Regularly audit third-party scripts and trackers to minimize privacy risks and ensure compliance with data protection regulations.

Technical notes

Notes

The website uses modern web technologies including Google Analytics, Google Tag Manager, Microsoft Clarity, and various marketing tools like Sleeknote and Typeform. The cookie consent banner is comprehensive and user-friendly, indicating good privacy awareness. The site appears mobile-optimized with responsive design and accessibility features at a basic level. Performance is moderate, with asynchronous loading of scripts to improve speed. However, no CMS or hosting provider information was detected. The absence of security headers and incomplete WHOIS data represent technical risks that should be addressed to improve overall site security and trust.
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.
