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

  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

ELVOREV holds a stable market position as a medium-sized energy sector service provider in the Czech Republic, with a clear focus on electrical installation and maintenance services. The company benefits from a diversified service portfolio and a long-standing reputation. Its business model revolves around direct service delivery to clients, supported by a structured web presence that highlights its subsidiaries and projects. The absence of phone or email contacts on the website may limit direct customer engagement but is partially mitigated by contact forms and physical address details. The partnership with a local web agency (asalonta.cz) indicates a professional approach to digital marketing. No affiliate or advertising networks beyond Google Tag Manager are used, suggesting a focus on organic and direct client acquisition.

Security posture

The website maintains a good security posture with enforced HTTPS and GDPR-compliant cookie consent mechanisms. However, it lacks visible security headers such as Content Security Policy, HSTS, or X-Frame-Options, which could enhance protection against common web attacks. No incident response or security policy information is published, which is a gap in transparency and preparedness. The use of common third-party scripts requires regular auditing to prevent vulnerabilities. No exposed sensitive data or known vulnerabilities were found in the HTML content. Overall, the security maturity is moderate but could be improved with additional headers and documented policies.

Recommendations

  1. Implement standard security headers (CSP, HSTS, X-Frame-Options) to strengthen web security.
  2. Publish a security policy and incident response contact information to improve transparency and readiness.
  3. Add explicit company contact emails and phone numbers on the website to enhance customer trust and communication.
  4. Regularly audit third-party scripts and plugins for vulnerabilities and update them promptly.
  5. Consider adding terms of service to clarify user agreements and legal protections.

Technical notes

Notes

The website is built on WordPress CMS with a modern front-end stack including jQuery and Swiper.js for interactive elements. Google Tag Manager is used for analytics, and Complianz plugin manages GDPR cookie compliance. The site is mobile responsive with adaptive images and CSS media queries. Performance is moderate, with asynchronous loading of scripts and deferred emoji scripts. Hosting appears to be via Czech providers consistent with the domain registrar. No major technical debt or deprecated technologies were detected. Opportunities exist to improve accessibility and SEO further by adding ARIA roles and structured data markup.
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.
