0–100, higher is better. How it is calculated

The website mo-je.cz represents a small Czech business specializing in technical SEO and online profile management services for platforms such as Firmy.cz, Mapy.cz, and Google Search. The business targets other companies seeking to improve their online visibility through sustainable SEO practices rather than paid advertising. The site is professionally designed with clear navigation and relevant content, though it lacks comprehensive privacy and cookie policies. Technically, the site uses modern web technologies including Google Tag Manager, Google Fonts, and Font Awesome icons, and appears mobile-optimized with moderate performance. Security posture is adequate but could be improved by adding security headers and formal policies. The absence of WHOIS data for the domain is a notable concern, reducing trustworthiness and raising questions about domain registration legitimacy. Overall, the site is functional and professional but would benefit from enhanced compliance and security measures.

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

    • 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

      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

mo-je.cz operates in a niche market providing technical SEO and business profile management services primarily for Czech businesses. The business model is service-based, focusing on one-time and ongoing profile management packages. The company leverages Google Analytics for tracking and positions itself as a specialist in long-term SEO benefits. The lack of social media presence and limited external partnerships suggest a small-scale operation. The clear contact details and professional content indicate a credible small business, though the missing WHOIS data and absence of formal policies may impact customer trust. Growth potential exists through expanding service offerings and improving digital compliance.

Security posture

The website employs HTTPS and uses Google Tag Manager for analytics, indicating basic security awareness. However, no security headers were detected, and no formal security or incident response policies are published. The absence of forms reduces attack surface, but the lack of privacy and cookie policies is a compliance gap under GDPR. No vulnerability disclosures or security.txt files are present, limiting transparency. The missing WHOIS data is a significant red flag for domain legitimacy. Overall, the security posture is moderate but requires improvements in policy transparency, header implementation, and domain registration verification to enhance trust and compliance.

Recommendations

  1. Implement and publish comprehensive privacy and cookie policies to improve GDPR compliance.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to enhance protection.
  3. Verify domain registration status and resolve WHOIS data absence to improve legitimacy and trust.
  4. Consider publishing a security.txt file and vulnerability disclosure policy to increase transparency.
  5. Enhance accessibility features and conduct regular security audits of third-party scripts.

Technical notes

Notes

The website uses a clean HTML5 structure with modern CSS and external resources including Google Fonts and Font Awesome icons. Google Tag Manager is used for analytics integration, indicating a moderate level of technical maturity. The site is mobile responsive and has clear navigation. No CMS or hosting provider information is detectable. Performance is moderate with no obvious technical debt. However, the lack of security headers and formal compliance documents suggests room for technical improvements. The absence of WHOIS data may indicate domain registration issues that should be addressed to avoid operational risks.
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.
