Risk levelHigh

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

JAKUB Group operates the e-centrum.cz website, a regional electrical supplies distributor primarily serving Moravia, Silesia, and parts of the Czech Republic and Slovakia. The company offers a broad catalog of electrical products, supplier listings, and an e-shop, supported by multiple branch locations. The website is professionally designed with clear navigation and relevant content targeting electrical professionals and businesses. Technically, the site uses legacy JavaScript libraries such as jQuery 1.10.2 and fancybox, alongside Google Analytics and Tag Manager for tracking. While the site is accessible and functional, it lacks modern security headers and uses outdated libraries, which may expose it to vulnerabilities. Privacy and cookie policies are absent, indicating compliance gaps with GDPR and related regulations. The WHOIS data is unavailable, reducing domain trustworthiness, though the business presence and partner domains suggest legitimacy. Overall, the site demonstrates moderate digital maturity with room for security and compliance improvements.

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

11 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

  2. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  3. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      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
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

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.

Technical appendix

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

Business context

Business profile

The company holds a strong regional market position in the energy sector, focusing on electrical components distribution. Its business model combines B2B and B2C sales through catalogs and an e-shop, supported by a network of regional partners and subsidiaries. The presence of multiple branch domains indicates a well-established partnership ecosystem. The target customers are electrical professionals and businesses in the Czech Republic and Slovakia. The company leverages digital marketing tools like Google Analytics but lacks explicit privacy and cookie compliance mechanisms. Growth opportunities exist in modernizing the technical stack and enhancing compliance to strengthen market trust.

Security posture

The website's security posture is moderate but has notable weaknesses. The use of outdated jQuery 1.10.2 introduces potential vulnerabilities. No security headers such as Content Security Policy or HSTS were detected, and privacy policies are missing, which may expose the company to regulatory risks. The site uses HTTPS, which is positive, but the absence of other security best practices limits its security maturity. Incident response and vulnerability disclosure mechanisms are not evident. The lack of WHOIS data further complicates trust assessment. Overall, the security culture appears basic and would benefit from targeted improvements in library updates, header implementation, and compliance documentation.

Recommendations

  1. Update all JavaScript libraries, especially jQuery, to current secure versions to mitigate known vulnerabilities.
  2. Implement comprehensive privacy and cookie policies to comply with GDPR and enhance user trust.
  3. Add and configure security headers such as Content Security Policy, HSTS, X-Frame-Options, and X-Content-Type-Options.
  4. Improve mobile optimization and accessibility to enhance user experience and SEO performance.
  5. Investigate and resolve WHOIS data availability issues to improve domain trustworthiness and transparency.

Technical notes

Notes

The website uses legacy front-end technologies including jQuery 1.10.2 and fancybox 2.1.5, which are outdated and may pose security risks. Google Analytics and Google Tag Manager are integrated for user tracking. The site loads CSS and JavaScript resources locally and asynchronously where possible, indicating some performance considerations. Mobile optimization is basic, with viewport meta tags present but no advanced responsive frameworks detected. Accessibility features are minimal. No CMS or hosting provider information is discernible from the HTML. Overall, the technical infrastructure is functional but dated, with modernization opportunities to improve security, performance, and compliance.
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.
