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

7 findings rated critical or high. Fix these first.

  1. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection
    • Critical

      Critical Service Exposed: PostgreSQL

      Port 5432 (PostgreSQL) is publicly accessible - PostgreSQL - Database server

      What to do: Immediately restrict access to PostgreSQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  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. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • High

      No DMARC record found

      DMARC provides email authentication and reporting

      What to do: Add DMARC record: "v=DMARC1; p=none; rua=mailto:dmarc@yourdomain.com"

  4. 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 · found on this site
  • 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

dBEL operates in the energy and technology sectors, targeting professionals involved in acoustic planning across multiple industries. Its SaaS business model offers specialized software tools and consulting services, supported by the parent company's extensive expertise. The company benefits from strategic partnerships with scientific data providers like IMMI and maintains a strong brand presence with consistent messaging and professional content. Growth potential is indicated by the platform's extensibility and custom solutions. The company maintains active communication channels and marketing efforts, including a blog and LinkedIn presence, enhancing market visibility and customer engagement.

Security posture

The website demonstrates a good security maturity level with HTTPS enforced and domain status protections such as clientDeleteProhibited and clientTransferProhibited. However, DNSSEC is not enabled, which could be improved to enhance DNS security. The site uses third-party analytics and tracking tools responsibly with user consent mechanisms in place. No exposed sensitive data or vulnerabilities were detected in the analysis. Security headers are partially implemented but could be strengthened by explicitly adding CSP, X-Frame-Options, and X-Content-Type-Options headers. Incident response and security policy pages are not present, indicating room for improvement in transparency and readiness.

Recommendations

  1. Enable DNSSEC to improve domain name system security and prevent DNS spoofing.
  2. Implement and verify comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Publish a dedicated security policy and incident response information to enhance transparency and trust.
  4. Regularly audit and update third-party scripts to mitigate potential vulnerabilities.
  5. Consider adding explicit data retention policies and GDPR compliance details in privacy documentation.

Technical notes

Notes

The website is built on TYPO3 CMS with Bootstrap for responsive design, ensuring good mobile optimization and accessibility. Hosting appears to be managed via OVH with DNS services on AWS, indicating a robust infrastructure. Performance is moderate with compressed CSS and JS assets, though further optimization could improve load times. SEO is well addressed with meta tags, canonical links, and hreflang attributes for multilingual support. The site uses modern analytics and consent management tools, reflecting a mature digital marketing approach. Technical debt appears low, but enabling DNSSEC and enhancing security headers would strengthen the overall technical posture.
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.
