Medium risk. 3 critical or high findings in SSL/TLS and Network security.

Security score

63/100

Risk levelMedium

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

FUNKE Wärmeaustauscher Apparatebau GmbH is a German-based specialist company focused on the development and production of industrial heat exchangers. The website presents a professional and consistent brand image targeting industrial clients and businesses requiring heat exchanger solutions. The company positions itself as a specialist in manufacturing within the industrial sector. Technically, the website is built on TYPO3 CMS and includes JavaScript tracking from sst.hydac.com, hosted on EuroDNS nameservers. The site demonstrates moderate performance and good mobile optimization but lacks advanced SEO and accessibility features. Security posture is moderate with HTTPS implied but no visible security headers or explicit security policies. Privacy compliance is weak due to the absence of privacy and cookie policies or consent mechanisms. Contact information and incident response details are not found, limiting direct communication channels. Overall, the website is safe for general audiences and professionally designed but would benefit from enhanced security and privacy transparency.

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. 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

  2. Network security

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

    • 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

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

The company operates in the manufacturing sector, specializing in industrial heat exchangers, serving industrial clients. The business model revolves around product development and manufacturing. The website content is relevant and targeted, but lacks detailed business disclosures such as founding year or parent company information. No partnerships or subsidiaries are explicitly mentioned. The presence of a tracking script indicates some level of user analytics. The company appears to maintain a moderate market position as a specialist manufacturer in Germany.

Security posture

The website uses HTTPS and is hosted on EuroDNS nameservers, indicating basic security infrastructure. However, no security headers such as Content-Security-Policy or X-Frame-Options are detected, which could expose the site to certain web-based attacks. No vulnerability disclosure or incident response information is provided, which is a gap in security transparency. The absence of privacy and cookie policies also indicates potential GDPR compliance issues. The tracking script from sst.hydac.com suggests user data collection but without clear privacy disclosures. Overall, the security posture is moderate but could be significantly improved with standard security best practices and compliance documentation.

Recommendations

  1. Publish comprehensive privacy and cookie policies with GDPR compliance details.
  2. Implement standard security headers to protect against common web vulnerabilities.
  3. Provide clear contact information including emails and phone numbers for business and security incidents.
  4. Add a vulnerability disclosure policy or security.txt file to enhance transparency and trust.
  5. Improve SEO and accessibility features to enhance user experience and compliance.

Technical notes

Notes

The website is built on TYPO3 CMS, a mature open-source content management system, indicating a stable technical foundation. The presence of a JavaScript tracking script from sst.hydac.com shows integration of analytics tools. The site uses modern CSS and responsive design techniques, ensuring good mobile optimization. Hosting is via EuroDNS nameservers, a reputable DNS provider. Performance is moderate with no explicit indicators of slow loading or technical debt. However, the lack of visible security headers and privacy compliance features suggests areas for technical improvement. The site could benefit from enhanced metadata, structured data, and accessibility improvements to meet modern web standards.
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.
