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

DOSON spol. s r.o. is a Czech family-owned company specializing in commercial security services since 1993. The company offers a comprehensive range of security solutions including physical guarding, alarm system monitoring with rapid response, retail security, occupational safety audits and training, security project planning, and additional facility services such as cleaning and maintenance. The company holds NBÚ certification for access to classified information and maintains significant insurance coverage, positioning itself as a trusted security provider in the Czech Republic. The website reflects a professional and consistent brand image targeting businesses requiring property and personnel protection services. Technically, the website is built on WordPress using the Enfold theme and incorporates modern web technologies including jQuery and Google Analytics. The site is mobile-optimized and provides a cookie consent mechanism compliant with basic GDPR requirements. However, it lacks explicit privacy and terms of service pages, which are important for full compliance and user trust. The site uses HTTPS with good SSL configuration but does not implement advanced security headers, which could enhance its security posture. From a security perspective, the site demonstrates good practices such as encrypted connections and cookie consent but could improve by adding security headers and incident response contact information. No vulnerabilities or exposed sensitive data were detected in the HTML content. The absence of WHOIS data limits domain trust assessment, but the website content and business information appear legitimate and professional. Overall, DOSON.cz is a credible and professional security services provider with a solid digital presence. Strategic improvements in privacy documentation and security headers would enhance compliance and trustworthiness.

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. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  4. 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"

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 · found on this site
  • 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

Business profile

DOSON operates in the commercial security sector within the Czech Republic, serving clients requiring physical security and related services. The company benefits from a long-standing market presence since 1993, leveraging its family-owned status and local expertise. Its business model focuses on service delivery including guarding, alarm monitoring, safety audits, and facility services. Revenue streams likely derive from contracts with commercial clients, retail centers, and possibly public sector entities. The company is a member of multiple professional security associations, enhancing its credibility and networking opportunities. The website indicates a focus on quality and compliance, with insurance and NBÚ certification as competitive advantages. There is no indication of parent or subsidiary companies, suggesting an independent operation. The company targets medium-sized to large organizations needing comprehensive security solutions.

Security posture

The website enforces HTTPS, ensuring encrypted communication. It implements a cookie consent mechanism with granular user controls, indicating awareness of privacy regulations. However, the absence of security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options represents a gap in defense-in-depth strategies. No incident response or security policy information is provided, limiting transparency on handling security events. The use of Google Analytics introduces moderate user tracking, but the site offers options to disable tracking. No exposed sensitive data or vulnerable libraries were identified in the HTML content. Overall, the security posture is moderate with room for improvement in headers and documented policies.

Recommendations

  1. Implement comprehensive privacy policy and terms of service pages to enhance legal compliance and user trust.
  2. Add security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen site security.
  3. Provide clear incident response contact information to improve transparency and readiness.
  4. Regularly audit and update third-party scripts and plugins to mitigate vulnerabilities.
  5. Enhance accessibility features and conduct periodic security assessments to maintain a robust security posture.

Technical notes

Notes

The website is built on a modern WordPress CMS platform using the Enfold theme, which is well-maintained and feature-rich. It uses jQuery and integrates Google Fonts and Google Analytics for enhanced user experience and analytics. The site is mobile responsive and has good SEO meta tags. Performance is moderate, with no major issues detected in the HTML structure. However, the site lacks advanced security headers and explicit privacy/legal documentation. Hosting provider details are not disclosed. The technical stack is standard for a professional service website but could benefit from modernization in security and privacy compliance aspects.
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.
