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. 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 operates in the energy and transportation sectors, focusing on HDD drilling services for infrastructure projects such as water and sewage pipelines. Its business model is service-oriented, targeting municipal utilities and construction firms. The website showcases references to completed projects, indicating operational experience and market credibility. The domain age and WHOIS data support the legitimacy and maturity of the business. No social media or advertising partnerships are evident, suggesting a focused, direct client engagement approach. Growth potential lies in expanding digital presence and formalizing compliance documentation.

Security posture

The website employs HTTPS with a valid SSL certificate and uses Google reCAPTCHA to protect its contact form from spam. A cookie consent banner with detailed category preferences demonstrates GDPR awareness. However, no explicit security policy or incident response information is published, and security headers like Content-Security-Policy or X-Frame-Options are not detected. No vulnerabilities or exposed sensitive data were found in the HTML content. The security posture is solid for a small business website but could be improved by publishing security policies and implementing additional HTTP security headers.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service pages to improve compliance and user trust.
  2. Implement and publicly document a security policy and incident response procedures.
  3. Add HTTP security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Regularly audit and update WordPress plugins and themes to mitigate vulnerabilities.
  5. Consider integrating social media channels and analytics tools with transparent privacy disclosures to enhance marketing and user insights.

Technical notes

Notes

The website is built on WordPress CMS using the Mesmerize theme and several plugins including Yoast SEO, Formidable Forms, and Cookie-Law-Info. It uses Google Fonts and Google reCAPTCHA for security. The site is mobile-optimized with responsive design and good SEO metadata including Open Graph and JSON-LD structured data. Performance is moderate with deferred JavaScript loading and optimized CSS. Hosting is provided by REG-ZONER, a Czech registrar and hosting provider, consistent with the business location. There is no evidence of outdated or vulnerable libraries in the provided HTML content. Opportunities exist to improve accessibility and implement advanced security headers.
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.
