0–100, higher is better. How it is calculated

Calta Elektro is a well-established Czech retailer specializing in premium electrical appliances from brands such as Miele, Jura, Liebherr, and Bora. Founded in 1990, the company operates physical stores and showrooms in Milevsko and Písek, alongside an e-commerce platform. Their business model focuses on retail sales supported by kitchen studio and lighting services, targeting consumers seeking high-quality branded products. The website reflects a professional and consistent brand image with clear navigation and relevant content for their audience. Technically, the website employs a modern technology stack including jQuery, Bootstrap, Google Analytics, and Google reCAPTCHA v3, hosted likely by REG-ZONER. The site is mobile-optimized and uses secure HTTPS connections. However, some security best practices such as security headers and published privacy/cookie policies are missing, indicating room for improvement in compliance and security posture. From a security perspective, the site shows good practices like HTTPS and CAPTCHA usage but lacks explicit security headers and incident response contacts. No vulnerabilities or exposed sensitive data were detected. The domain WHOIS data is consistent with the business claims, showing a long-standing domain registration that supports legitimacy. Overall, the website is trustworthy and professionally maintained but would benefit from enhanced privacy compliance and security hardening to meet modern standards and regulations.

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.

Priority findings

9 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

  2. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

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 · found on this site
  • 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.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

Calta Elektro holds a solid position in the Czech retail market for premium electrical appliances, leveraging well-known brands to attract discerning customers. Their diversified offerings include kitchen studios and lighting solutions, which complement their core appliance sales and create additional revenue streams. The company’s longevity since 1990 and multiple physical locations indicate stable operations and local market trust. Their partnership ecosystem includes related domains for e-commerce and specialized product lines, as well as a credited web development partner. Growth indicators include a maintained online presence and integration of modern marketing tools like ShareThis and Google Analytics. Strategic observations suggest focusing on expanding digital compliance and security to enhance customer trust and regulatory adherence.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and use of Google reCAPTCHA v3 to protect forms from automated abuse. However, the absence of key security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security reduces the overall security posture. There is no published security or incident response policy, which limits transparency and readiness for handling security incidents. No vulnerabilities or exposed sensitive data were found in the HTML content. Compliance gaps exist due to missing privacy and cookie policies, which are critical under GDPR. The security culture appears basic but functional, with opportunities to improve through formal policies and enhanced technical controls.

Recommendations

  1. Publish comprehensive privacy and cookie policies to improve GDPR compliance and user trust.
  2. Implement security headers including Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and Strict-Transport-Security to harden the website against common attacks.
  3. Add a dedicated security or incident response contact email (e.g., security@caltaelektro.cz) to facilitate vulnerability reporting and incident management.
  4. Regularly audit and update third-party scripts and libraries to mitigate risks from vulnerable dependencies.
  5. Develop and publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting and demonstrate security commitment.

Technical notes

Notes

The website is built on a custom or Nette-based CMS platform, utilizing a modern front-end stack with jQuery, Bootstrap, and various JavaScript libraries for UI enhancements and sliders. Google Analytics and ShareThis provide analytics and social sharing capabilities. The site is hosted on servers managed by REG-ZONER, a known Czech hosting provider. Performance is moderate with good mobile optimization and SEO meta tags present. Some legacy code comments and unused scripts suggest minor technical debt. The absence of security headers and formal privacy mechanisms indicates areas for modernization. Overall, the technical infrastructure supports the business needs but would benefit from security and compliance upgrades to reduce risk and improve user trust.
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.
