Medium risk. 5 critical or high findings in GDPR outside view and SSL/TLS.
mBank.cz is a well-established online banking platform serving retail customers in the Czech Republic. The website offers a comprehensive range of financial services including current accounts (mKonto), loans, mortgages, debit and credit cards, savings products, insurance, and digital banking solutions such as mobile apps and contactless payments. The site is professionally designed with clear navigation and strong branding consistency, targeting individuals seeking convenient and modern banking services. The business model focuses on digital-first banking, emphasizing ease of use and accessibility. Technically, the website employs a modern technology stack including jQuery, Google Tag Manager, and a proprietary CMS (StartWeb6.0). It is mobile-optimized and accessible, with good SEO practices and performance. The site uses HTTPS and implements cookie consent mechanisms, reflecting a mature digital infrastructure. However, some security headers are not explicitly detected, and no public vulnerability disclosure or security.txt file is found. From a security perspective, the site demonstrates good practices such as HTTPS enforcement, privacy policy transparency, and no visible sensitive data exposure. The absence of WHOIS data limits domain registration trust analysis, but the overall professionalism and compliance with GDPR indicate a legitimate and trustworthy operation. No WAF or blocking mechanisms were detected, allowing full content access. Overall, mBank.cz presents a secure, user-friendly, and compliant online banking platform with strong business credibility. Strategic improvements could include enhanced security header implementation and publishing a formal vulnerability disclosure policy to further strengthen trust and 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.
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.
