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

      Missing X-Frame-Options header

      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

      • ASVS V3.4.3

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 is positioned as a specialized SEO consultant with a focus on delivering measurable results to clients, supported by case studies and testimonials. The market positioning is strong within the Czech SEO niche, leveraging media mentions and a consistent brand presence. Revenue streams are likely service fees from SEO consulting and project management. The target customer segment includes SMEs and e-commerce businesses looking to improve their online visibility. The partnership ecosystem includes social media channels but no explicit business partners or subsidiaries. Growth indicators include multiple case studies and ongoing client relationships. Strategic observations suggest maintaining focus on client success stories and expanding service offerings could enhance market share.

Security posture

The website demonstrates a basic to moderate security maturity level. HTTPS is enforced, and cookie consent is implemented in compliance with GDPR. However, the absence of security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options reduces the overall security posture. No vulnerability disclosure or incident response information is provided, which could hinder timely reporting and mitigation of security issues. The use of third-party scripts like Google Tag Manager and CookieConsent.js is standard but requires regular auditing to prevent supply chain risks. Overall, the security culture appears functional but could benefit from formalized policies and enhanced technical controls.

Recommendations

  1. Implement additional HTTP security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web vulnerabilities.
  2. Publish a dedicated security policy page and include incident response contact information to improve transparency and readiness.
  3. Add a security.txt file to facilitate responsible vulnerability disclosure from external researchers.
  4. Regularly audit and update third-party plugins and scripts to minimize exposure to known vulnerabilities.
  5. Enhance accessibility features to improve compliance and user experience for all visitors.

Technical notes

Notes

The website is built on a WordPress CMS platform using the Yoast SEO plugin for search engine optimization and Google Tag Manager for analytics and tracking. The site loads CSS and JavaScript assets efficiently and includes responsive design elements for mobile optimization. Cookie consent is managed via a third-party JavaScript library, ensuring GDPR compliance. Performance is moderate, with potential improvements in caching and asset optimization. The technical stack is modern but could be enhanced with additional security headers and accessibility improvements. No hosting provider information was detected from the HTML content. Overall, the technical infrastructure supports the business goals but has room for modernization and security hardening.
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.
