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

8 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

    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

      • 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 business targets clients seeking SEO and digital marketing services, leveraging a service-based model with offerings ranging from individual SEO tasks to full-service project management. The presence of detailed case studies and client feedback suggests a focus on building credibility and demonstrating measurable results. The company operates independently without subsidiaries or parent companies, maintaining a small business profile. Partnerships with design agencies like Digilabs.cz enhance its service delivery. The website's content and social media integration support ongoing client engagement and marketing efforts.

Security posture

The website employs HTTPS and a cookie consent mechanism aligned with GDPR requirements, indicating a baseline commitment to user privacy and security. However, the absence of explicit security headers and incident response information suggests potential gaps in defense-in-depth strategies. No vulnerabilities or exposed sensitive data were detected in the HTML content. The lack of a security.txt file or dedicated security policy page limits transparency for vulnerability reporting. Overall, the security posture is moderate but could benefit from enhancements to align with best practices and improve incident readiness.

Recommendations

  1. Implement comprehensive HTTP security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  2. Publish a security policy or security.txt file to facilitate responsible vulnerability disclosure and incident reporting.
  3. Enhance accessibility features to improve compliance and user experience for all visitors.
  4. Regularly audit third-party scripts and plugins to mitigate risks from vulnerable dependencies.
  5. Consider adding explicit contact information such as company email and phone number to improve trust and communication.

Technical notes

Notes

The website is built on WordPress CMS version 5.8.10, utilizing Yoast SEO plugin for SEO optimization and Google Tag Manager for analytics and tracking. The use of Google Fonts and SVG icons contributes to a modern and visually appealing design. CookieConsent.js is employed for GDPR-compliant cookie management. Performance is moderate with no evident blocking scripts or errors. Mobile optimization is good, with responsive navigation and layout. However, the site lacks advanced accessibility features and some security headers, which could be addressed to improve overall technical robustness.
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.
