Security report for heureka.group
Heureka Group a.s. · Technology · Czech Republic
Medium risk. 7 critical or high findings in Security headers, GDPR outside view and 2 other checks.
Heureka Group a.s. is a Czech-based technology company specializing in e-commerce solutions and services, targeting e-shops and business partners primarily in the Czech Republic and surrounding regions. The company operates a website with bilingual support (Czech and English) and offers contact channels including phone and a contact form. The website employs modern digital marketing and analytics tools such as Google Tag Manager and Visual Website Optimizer, indicating a focus on data-driven optimization and user experience improvements. However, the absence of a published privacy policy and terms of service represents a compliance gap that should be addressed promptly. From a technical perspective, the website uses Cloudflare DNS services and loads multiple third-party scripts for analytics and privacy management. The site is moderately optimized for performance and mobile devices but lacks some advanced SEO and accessibility features. Security posture is adequate with HTTPS enabled and domain registration consistent with the business identity, but the lack of DNSSEC and missing security headers suggest room for improvement. Security-wise, the site does not expose sensitive data and uses reputable third-party services, but it lacks published security policies and incident response contacts. The domain registration is transparent and consistent with the company's claimed identity, enhancing trustworthiness. Overall, the website is functional and moderately secure but requires enhancements in privacy compliance and security best practices to improve its risk profile and user trust. Strategic recommendations include implementing a comprehensive privacy policy, enabling DNSSEC, adding security headers, and publishing incident response procedures. These steps will strengthen compliance, security posture, and customer confidence.

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.

Missing Content-Security-Policy header
Controls resources the browser is allowed to load
What to do: Implement a Content-Security-Policy appropriate for your application
- ASVS V3.4.3

Results by check
Each check with its score, findings and the evidence it collected.
How this score is calculated
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.

Not counted
- NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
- OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.
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.
- The certificate is not trusted by browsers
- The website is not served over HTTPS
- A database, remote desktop, file-sharing or Telnet service is reachable from the internet
- The page loads a script from a compromised source
- The domain registration has expired
- SPF authorises every server to send mail as the domain
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.

Notes
Standards and sources
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.
