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. 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
    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • 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. 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';…

  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 · 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

BRANDES GmbH operates in the energy sector, targeting energy providers, industrial clients, and infrastructure operators. Their competitive advantage lies in their proprietary NiCr sensor technology and long-standing industry experience. The business model combines product sales with value-added services such as consulting, installation, and training. The company maintains a professional online presence with clear contact channels and social media engagement. Partnerships with certification bodies and a reputable hosting provider further strengthen their market credibility. Growth indicators include recent news updates and participation in industry events. The company’s ecosystem includes trusted partners like Parrot Media for hosting and digital marketing.

Security posture

The website demonstrates a solid security foundation with HTTPS, cookie consent management, and secure form handling. Use of Google Tag Manager and Analytics is managed with user consent, aligning with GDPR requirements. However, the absence of explicit security policies, incident response contacts, and vulnerability disclosure mechanisms represents a gap in transparency and readiness. No critical vulnerabilities or exposed sensitive data were detected. Security headers appear minimal or absent, suggesting room for improvement in defense-in-depth strategies. Overall, the security posture is good but could be enhanced by publishing formal policies and implementing additional HTTP security headers.

Recommendations

  1. Implement and publish a formal security policy and incident response contact information on the website.
  2. Add HTTP security headers such as Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and X-XSS-Protection to strengthen security posture.
  3. Consider creating a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  4. Maintain and regularly update cookie consent mechanisms to ensure ongoing GDPR compliance.
  5. Enhance transparency by including terms of service and data protection officer contact details if applicable.

The website is built on TYPO3 CMS, a mature and widely used content management system, indicating a stable and scalable infrastructure. The integration of Google Tag Manager and Analytics is done with consent management, reflecting good privacy practices. Hosting is managed by Parrot Media, as indicated by the nameservers, suggesting a professional hosting environment. The site is mobile-optimized and accessible, with good SEO practices including meta tags and structured navigation. Performance is moderate, with compressed CSS and JavaScript assets. There is no indication of outdated or vulnerable libraries. Opportunities exist to improve security headers and formalize security documentation to reduce technical risks.
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.
