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

    • 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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  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 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

Linki.cz holds a strong niche position as an SEO and link building expert with over 15 years of experience. The business model revolves around consultancy and service provision to digital marketers and website owners. The company leverages partnerships with SEO tool providers and maintains a visible social media presence. Revenue streams likely include consulting fees, training sessions, and affiliate management. The website content and testimonials indicate a credible reputation with notable clients. Growth potential exists through expanding educational content and enhancing compliance to meet GDPR requirements.

Security posture

The website demonstrates a moderate to good security maturity level with HTTPS enforced and no visible sensitive data leaks. However, the absence of explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options represents a gap. No vulnerability disclosure or incident response information is published, limiting transparency. The use of third-party scripts like Google Analytics and SumoMe introduces moderate tracking but no evident vulnerabilities. GDPR compliance is incomplete due to missing privacy and cookie policies. Overall, the security posture is adequate but could be strengthened with better header implementation and compliance documentation.

Recommendations

  1. Implement and publish a comprehensive privacy policy and cookie consent mechanism to ensure GDPR compliance.
  2. Add explicit security headers (Content-Security-Policy, X-Frame-Options, X-Content-Type-Options) to enhance protection against common web attacks.
  3. Create and publish a security.txt file and incident response contact information to improve vulnerability disclosure and incident handling transparency.
  4. Regularly audit and update third-party scripts and plugins to mitigate potential vulnerabilities.
  5. Enhance accessibility features and conduct periodic security assessments to maintain a robust security posture.

Technical notes

Notes

The website runs on WordPress CMS with Elementor page builder and several plugins including Modern Events Calendar Lite and Ultimate Blocks. It uses Google Analytics and Google Tag Manager for tracking, and Font Awesome for icons. The site is mobile optimized and uses preconnect and preload hints for performance. The HTML is valid and SEO metadata is well implemented including Open Graph and JSON-LD structured data. Performance is moderate with some deferred scripts and lazy loading. Hosting provider is not explicitly identified. There is room for improvement in accessibility and security header implementation. Overall, the technical stack is modern and suitable for the business needs.
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.
