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

CS Technologies s.r.o. is a Czech digital agency specializing in the creation of websites, e-shops, applications, and online marketing services. With over 12 years of experience and more than 1300 projects completed, the company targets businesses seeking professional digital solutions and marketing support. Their service portfolio includes custom e-shop development, web design, PPC campaigns, SEO, social media management, application development, and video production through a partner company. The website is well-structured, professionally designed, and optimized for mobile devices, reflecting a mature digital presence. Technically, the site uses common web technologies such as jQuery, Font Awesome, Google Fonts, and Google Tag Manager for analytics and marketing. Security-wise, the site implements cookie consent mechanisms and uses HTTPS, but lacks visible advanced security headers and explicit security policies. The absence of WHOIS data limits domain trust verification, though the business presence and social media links support legitimacy. Overall, the site presents a solid business and technical foundation with room for security and compliance enhancements.

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

5 findings rated critical or high. Fix these first.

  1. 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

    • High

      No SPF record found

      SPF helps prevent email spoofing

      What to do: Add SPF record: "v=spf1 include:_spf.yourmailprovider.com ~all"

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

  3. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

  4. Network security

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

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • 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

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 company operates as a B2B digital agency in the technology sector, focusing on web and e-commerce development alongside online marketing services. Their competitive advantage lies in a comprehensive service offering and a strong track record demonstrated by numerous client references and testimonials. The business model is project-based with a focus on customized solutions. The target market includes SMEs and larger enterprises in the Czech Republic seeking digital transformation and marketing growth. Partnerships, such as with csproduction.cz for video production, enhance their service ecosystem. The company maintains a professional brand image and consistent messaging, supporting growth and client trust.

Security posture

The website demonstrates a moderate security posture with HTTPS enabled and cookie consent implemented, indicating awareness of privacy regulations. However, the lack of visible security headers (e.g., CSP, HSTS) and absence of published security policies or incident response contacts suggest areas for improvement. No vulnerabilities or exposed sensitive data were detected in the HTML content. The missing WHOIS data reduces domain trust and could be a risk factor. Overall, the security maturity is adequate for the business type but would benefit from formalized policies and enhanced technical controls.

Recommendations

  1. Implement comprehensive security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options to enhance protection against common web attacks.
  2. Publish explicit security and privacy policies, including incident response procedures and contact channels for security issues.
  3. Conduct regular audits of third-party scripts and libraries to ensure no vulnerabilities are introduced.
  4. Enhance accessibility features to improve compliance and user experience for all visitors.
  5. Verify and publish domain registration details to improve trust and legitimacy perception.

Technical notes

Notes

The website uses a standard technology stack including jQuery, Font Awesome, Google Fonts, and Google Tag Manager. The CMS appears to be EasyWeb, inferred from textual references. Performance is moderate with a responsive design suitable for mobile devices. SEO is supported by meta tags and structured navigation. However, no advanced frameworks or modern JavaScript libraries were detected. The site could benefit from performance optimization and accessibility improvements. Hosting provider details are not disclosed. Overall, the technical infrastructure is stable but could be modernized to improve speed and security.
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.
