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

CSF, s.r.o. is a well-established Czech IT company founded in 2005, specializing in comprehensive IT infrastructure solutions, hardware supply, audiovisual technology, cloud services, and financial leasing options. The company targets businesses and educational institutions within the Czech Republic, leveraging over 24 years of local market experience and strong partnerships with major hardware vendors. Their website reflects a professional and consistent brand image with clear service offerings and contact information. Technically, the site uses modern tracking and analytics tools with proper cookie consent mechanisms, though it lacks explicit security policy documentation and incident response contacts. Security posture is solid with HTTPS and secure forms but could be improved with additional headers and transparency. Overall, the domain registration data aligns well with the business claims, supporting legitimacy 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

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

  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 Content-Security-Policy header

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

CSF holds a strong market position as a trusted IT partner in the Czech Republic, offering a broad portfolio from hardware to cloud and financial services. Their business model combines product sales with managed services and leasing, targeting medium-sized enterprises and public sector clients. The company benefits from certifications by leading technology brands and showcases references from reputable clients, enhancing credibility. Growth potential is supported by diversified offerings including education sector IT solutions and financial services. The partnership ecosystem is robust, though no explicit related domains were identified. Strategic focus on local market needs and compliance with GDPR further strengthen their competitive advantage.

Security posture

The website demonstrates a moderate to good security maturity level with HTTPS enforcement, cookie consent management, and secure data collection forms. However, it lacks published security policies, incident response contacts, and vulnerability disclosure mechanisms, which are important for transparency and trust. No critical vulnerabilities or exposed sensitive data were detected. The use of multiple third-party analytics and tracking services is managed via consent, aligning with privacy regulations. Recommendations include implementing security headers, publishing a formal security policy, and establishing incident response communication channels to enhance security culture and compliance.

Recommendations

  1. Publish a comprehensive security policy and make it accessible on the website.
  2. Add incident response contact information such as security@ or abuse@ email addresses.
  3. Implement and publish a vulnerability disclosure policy or security.txt file.
  4. Enhance HTTP security headers including Content-Security-Policy and X-Frame-Options.
  5. Improve accessibility features to meet higher standards and broaden user inclusivity.

Notes

The website is built on a custom or unknown CMS platform using modern JavaScript libraries like jQuery 3.6.3 and integrates multiple analytics and marketing tools including Google Tag Manager, Microsoft Clarity, and LinkedIn Insight. Performance is moderate with good mobile optimization and SEO practices. Hosting appears local and stable with a domain age consistent with business claims. Technical debt is minimal but opportunities exist to improve accessibility and security headers. The site uses a cookie consent mechanism compliant with GDPR, reflecting a mature approach to privacy. Overall, the technical infrastructure supports the business needs effectively with room for incremental improvements.
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.
