Klenk & Meder GmbH is a well-established Austrian family-owned company specializing in electrical engineering services with over 55 years of experience and a workforce of approximately 750 employees. The company offers a broad range of services including electrical installation, network technology, photovoltaic systems, maintenance, and sales of electrical materials and devices. Their market position is strong within Austria, supported by a network of subsidiaries and partners. The website is professionally designed, content-rich, and targets both private and business customers as well as apprentices. Technically, the site is built on TYPO3 CMS with modern JavaScript libraries and good SEO practices, but suffers from a critical lack of HTTPS security due to an invalid or missing SSL certificate. The security posture is weak, lacking HTTPS and advanced security headers, which poses a significant risk. Privacy compliance is well addressed with a comprehensive cookie consent mechanism and GDPR-aligned privacy policy. Overall, the business credibility is high with clear contact information, certifications, and trust signals. Strategic improvements in security infrastructure are recommended to enhance trust and protect user data.

Security Posture Analysis
Comprehensive Security Assessment
The website’s security posture is currently weak due to the absence of a valid SSL certificate and HTTPS support, which is a critical vulnerability. While some security headers like X-Content-Type-Options are present, important protections such as HSTS, Content-Security-Policy, and OCSP stapling are missing. The site uses HttpOnly and SameSite cookies, which is positive. No known vulnerabilities or malware were detected in the scripts or libraries used. The cookie consent mechanism is robust and GDPR compliant, but the lack of HTTPS undermines overall security and user trust. No explicit security or incident response policies are published on the site, indicating a potential gap in security governance. Immediate remediation of SSL issues and enhancement of security headers are essential to improve the security posture and protect user data.
Strategic Recommendations
Priority Actions for Security Improvement
Obtain and properly configure a valid SSL/TLS certificate to enable HTTPS across the entire site.
