High risk. 18 critical or high findings in GDPR outside view, Network security and 1 other check.
The website www.klientskyportal.cz serves as a client login portal primarily for financial services, targeting customers in the Czech Republic. It provides secure access to client accounts and integrates modern technologies such as Material Design, Google Analytics, Microsoft Clarity, and a custom chatbot for customer support. The presence of GDPR-compliant cookie consent mechanisms indicates attention to privacy regulations. However, the absence of WHOIS registration data and lack of explicit business contact information on the login page reduce transparency and business credibility. Technically, the site employs a moderate performance stack with good mobile optimization and basic accessibility features. Security posture is solid with HTTPS and cookie consent, but could be improved by adding explicit security headers and ensuring secure form handling. Overall, the site appears legitimate and professional but would benefit from enhanced business transparency and security hardening.

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.
