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

10 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. 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

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  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 · 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

The portal occupies a niche in the Czech electrical engineering market, offering specialized content and community features such as forums and event listings. Its business model combines content provision with advertising and training services. The domain's long history and consistent WHOIS data reinforce its market position. Partnerships with related domains like elektrika.info and elektrika.tv expand its ecosystem. The site targets professionals requiring up-to-date technical knowledge and regulatory information, supporting ongoing education and industry networking. Growth potential lies in expanding digital services and enhancing security and compliance transparency.

Security posture

Elektrika.cz employs HTTPS and basic security best practices including cookie consent. However, it lacks advanced security headers and explicit security or incident response documentation. The use of third-party advertising and analytics scripts introduces moderate tracking and potential risk vectors. No vulnerabilities or exposed sensitive data were detected in the analyzed content. The security posture is adequate for an informational portal but could be improved by implementing additional HTTP security headers, publishing security policies, and conducting regular security audits.

Recommendations

  1. Implement HTTP security headers such as Content-Security-Policy, Strict-Transport-Security, and X-Frame-Options to enhance protection against common web attacks.
  2. Publish a dedicated security policy and incident response plan to improve transparency and preparedness.
  3. Regularly review and update third-party scripts and advertising integrations to minimize security risks.
  4. Enhance mobile optimization and accessibility to improve user experience across devices.
  5. Consider adding terms of service and vulnerability disclosure information to strengthen legal and security posture.

Technical notes

Notes

The website is built on the Plone CMS platform, a mature and secure content management system. It uses JavaScript libraries including jQuery and integrates advertising via Revive Adserver. Google Analytics is used for visitor tracking. The site has a moderate performance profile with basic mobile responsiveness and accessibility features. SEO is supported by appropriate meta tags and structured navigation. Hosting appears to be managed through REG-WEBGLOBE with Czech-based nameservers, aligning with the site's regional focus. Opportunities exist to modernize front-end technologies and improve performance and accessibility 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.
