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

Elektro revize Zlín s.r.o. is a small, specialized service provider based in the Czech Republic focusing on electrical inspection services for devices up to 35 kV. The company offers a range of services including inspections of electrical installations up to 1000 V and above, electrical appliances, lightning rods, emergency lighting, and electrical machinery. The website is professionally designed with detailed service descriptions and pricing information, targeting businesses and individuals in the Zlín region requiring compliance with Czech electrical safety standards. Technically, the website uses legacy technologies such as jQuery 1.10.2 and integrates Google Analytics and Google Tag Manager for user tracking. The site is moderately optimized for performance and mobile use but lacks advanced accessibility features. There is no evidence of a CMS or modern frameworks. Security headers and HTTPS configuration details are not available, and the site does not provide privacy or cookie policies, which impacts compliance and user trust. From a security perspective, the site does not expose sensitive data or forms but uses outdated JavaScript libraries that could pose risks. The absence of privacy and cookie policies and missing WHOIS registration data reduce the overall trustworthiness and compliance posture. No WAF or blocking mechanisms were detected, and the site content is safe and appropriate for general audiences. Overall, the website presents a legitimate local business with good content quality but has gaps in privacy compliance, security best practices, and domain registration transparency. Strategic improvements in these areas would enhance trust and security posture.

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.

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. Security headers

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

Elektro revize Zlín s.r.o. operates in the energy sector, providing essential electrical inspection services aligned with Czech technical standards. The company appears to have a focused local market presence in the Zlín region, serving both commercial and residential clients. Their business model is service-oriented, relying on compliance-driven inspections and certifications. The detailed pricing tables and normative references suggest a transparent and professional approach. However, the lack of visible contact information and absence of digital marketing or social media presence may limit growth and customer engagement. The company does not appear to have subsidiaries or parent companies, indicating an independent small business. The use of Google Analytics indicates some level of digital marketing awareness, but privacy compliance is lacking. Overall, the company holds a stable niche position with opportunities for digital and compliance enhancements.

Security posture

The website demonstrates a basic security posture with no visible forms or sensitive data exposure, reducing immediate risk. However, the use of an outdated jQuery version (1.10.2) introduces potential vulnerabilities. The absence of security headers and lack of visible HTTPS confirmation are concerns. No privacy or cookie policies are present, indicating non-compliance with GDPR and related regulations. The missing WHOIS data further reduces domain trustworthiness. There is no evidence of incident response or security policy documentation. Tracking via Google Analytics and Tag Manager is implemented without visible user consent mechanisms, which may violate privacy regulations. Overall, the security maturity is low to moderate, with significant room for improvement in compliance, transparency, and technical security controls.

Recommendations

  1. Implement and publish comprehensive privacy and cookie policies to ensure GDPR compliance.
  2. Upgrade JavaScript libraries to current secure versions to mitigate known vulnerabilities.
  3. Add security headers such as Content-Security-Policy, X-Frame-Options, and HSTS to enhance protection.
  4. Provide clear and accessible contact information including emails and phone numbers to improve business credibility.
  5. Verify domain registration details and ensure WHOIS information is complete and accurate to increase trust.

Technical notes

Notes

The website is built using legacy JavaScript libraries, primarily jQuery 1.10.2, and uses Google Analytics and Google Tag Manager for tracking. The HTML structure is valid with proper meta tags for SEO and Open Graph for social sharing. CSS stylesheets are linked externally, and a colorbox plugin is used for image galleries. The site lacks modern frameworks or CMS indications and shows basic mobile optimization. Performance is moderate with no explicit speed optimizations detected. Accessibility features are minimal, and no ARIA roles or landmarks are evident. The site does not use HTTPS headers or security headers visibly, and no forms or input validation mechanisms are present. Overall, the technical infrastructure is functional but dated, with opportunities for modernization and security enhancements.
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.
