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

7 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

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  2. 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"

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

Elkova operates in the energy sector focusing on electrical installations and related services. Their competitive advantage lies in their 20 years of experience and comprehensive service portfolio covering installation, inspection, security systems, and renewable energy solutions. The business model is service-oriented, targeting homeowners, businesses, and developers in a defined geographic region. The presence of certifications and customer testimonials enhances credibility. The company leverages partnerships with known brands (e.g., Jablotron, Samsung) as indicated by logos on the site. Growth potential is supported by expanding service offerings such as photovoltaic installations. The company maintains direct customer engagement through phone and email contacts and a contact form, facilitating lead generation and support.

Security posture

The website enforces HTTPS and uses security and anti-spam plugins to protect forms and user interactions. Cookie consent mechanisms are implemented, supporting GDPR compliance. However, no explicit security headers were detected, and there is no published security policy or incident response plan visible on the site. No vulnerabilities or exposed sensitive data were found in the analysis. The security score is good but could be enhanced by implementing recommended HTTP headers and publishing security policies. Incident response contact channels are not provided, which is a gap in security readiness. Overall, the security posture is adequate for a small business website but lacks advanced security transparency.

Recommendations

  1. Implement HTTP security headers such as Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to enhance protection against common web attacks.
  2. Publish a clear security policy and incident response plan on the website to improve transparency and preparedness.
  3. Add a security.txt file to facilitate vulnerability disclosure and improve trust with security researchers.
  4. Regularly update WordPress core and plugins to mitigate risks from known vulnerabilities.
  5. Consider adding social media presence links to improve marketing reach and trust signals.

Technical notes

Notes

The website is built on WordPress CMS using a combination of Bootstrap for responsive design and jQuery-based plugins for sliders, carousels, and popups. SEO is managed via Yoast SEO plugin, and spam protection is handled by Zero Spam and WPBruiser. Google Fonts and Google Maps API are integrated for enhanced user experience. The site uses W3 Total Cache for performance optimization. The hosting provider is likely Active24, consistent with the registrar information. Performance is moderate with good mobile optimization. Accessibility is basic but could be improved. The technical stack is modern and well-maintained, suitable for a small business website. There are no indications of technical debt or critical risks, but security header implementation is missing.
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.
