Low risk. 4 critical or high findings in GDPR outside view and SSL/TLS.
Nux s.r.o. is a Czech technology company specializing in web development, online office solutions, and comprehensive internet consulting services. Established in 2004, the company has a solid market presence in the Czech Republic, targeting businesses and organizations seeking tailored digital solutions. Their offerings include custom software development, e-learning platforms, client portals, e-commerce solutions, and communication tools such as Mattermost and Jitsi. The website reflects a professional and consistent brand image with clear service descriptions and client references. Technically, the website employs modern technologies including Tailwind CSS, Google Tag Manager, and Google reCAPTCHA, indicating a mature digital infrastructure. The site is mobile-optimized and demonstrates good SEO practices, although accessibility features could be enhanced. The CMS used is a proprietary or custom system (cms1.nux.cz), and the site is served over HTTPS with a good SSL configuration. From a security perspective, the site enforces HTTPS and uses reCAPTCHA to mitigate automated abuse. However, explicit security headers are not evident, and there is no published security policy or incident response contact information. Cookie consent is implemented, supporting GDPR compliance, but no explicit privacy policy or terms of service were found on the main page. The WHOIS data confirms the domain's legitimacy and long-term registration consistent with the company's history. Overall, the website presents a low-risk profile with good business credibility and technical implementation. Strategic improvements include publishing comprehensive privacy and security policies, enhancing accessibility, and implementing additional security headers to strengthen the security 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.

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

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.
