Proxmox Server Solutions GmbH · Technology · Germany
Low risk. 2 critical or high findings in SSL/TLS.
Proxmox Server Solutions GmbH is a well-established German technology company founded in 2004, specializing in open-source server solutions including virtualization, backup, and email security platforms. Their market position is strong within the enterprise and IT professional segments, offering both free open-source software and paid enterprise support, training, and consulting services. The website reflects a mature digital presence with a professional design, clear navigation, and comprehensive content tailored to their target audience. Technically, the website is built on Joomla CMS with modern frameworks like Bootstrap 5 and uses Matomo for privacy-conscious analytics. The site is mobile-optimized, accessible, and SEO-friendly, indicating a high level of digital maturity. Security practices include HTTPS enforcement and a robust cookie consent mechanism, though some advanced security headers and explicit security policies are not present. The security posture is solid with no visible vulnerabilities or exposed sensitive data. The domain WHOIS data aligns well with the business claims, showing a long-standing registration and no privacy protection, which supports legitimacy. However, the absence of a published security policy or incident response contact is a minor gap. Overall, Proxmox demonstrates a trustworthy, professional, and secure online presence suitable for enterprise customers. Strategic improvements in security transparency and DNSSEC implementation could further enhance their posture.
Scanned
NIS2 Art. 21(2)
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.
2 findings rated critical or high. Fix these first.
TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.
Server supports weak protocols: TLSv1.1
What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions
SSL certificate uses 256-bit key, which is considered weak
What to do: Use at least 2048-bit RSA or 256-bit ECC key

Each check with its score, findings and the evidence it collected.
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.

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.
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.

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.
Automated reading of the public site. Ratings are indicative.
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.
