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

JCHP s.r.o. is a Czech Republic-based event production company specializing in BTL marketing activities since 2005. The company offers comprehensive event production services including in-house design, technical support, and 360° marketing campaigns. Their market position is strengthened by multiple industry awards and a loyal client base including prominent brands. The website is professionally designed, mobile-optimized, and uses modern web technologies such as Webflow CMS, Google Tag Manager, and iframe-lightbox for enhanced user experience. Security posture is good with HTTPS and cookie consent mechanisms implemented, though explicit security headers and incident response policies are absent. WHOIS data is unavailable, which slightly impacts trust but the overall business credibility remains high based on website content and certifications. Strategic recommendations include improving security headers, publishing a security.txt file, and enhancing transparency around incident response.

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

2 findings rated critical or high. Fix these first.

  1. 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
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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 in the event production sector with a focus on BTL marketing, serving medium-sized businesses and large clients in the Czech Republic and internationally. Their business model revolves around full-service event management, including design, technical execution, and marketing. Revenue streams likely come from event contracts and marketing campaigns. The company demonstrates strong growth and market presence through awards and repeat clients. Partnerships with recognized brands and a professional digital presence support their competitive advantage. The absence of phone contact details may limit direct customer engagement channels. Overall, JCHP s.r.o. is positioned as a reputable and established player in the event production industry.

Security posture

The website employs HTTPS with a valid SSL certificate, ensuring encrypted communications. Cookie consent is implemented with granular user controls, supporting GDPR compliance. However, the absence of security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options represents a missed opportunity to harden the site against common web attacks. No security.txt or incident response contact information is provided, which could hinder vulnerability reporting and incident management. No exposed sensitive data or vulnerable libraries were detected. Overall, the security maturity is moderate with room for improvement in headers and incident response readiness.

Recommendations

  1. Implement comprehensive security headers (CSP, X-Frame-Options, X-Content-Type-Options) to enhance protection against web attacks.
  2. Publish a security.txt file to facilitate responsible vulnerability disclosure and improve incident response communication.
  3. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.
  4. Consider adding explicit security and incident response policies on the website to increase transparency and trust.
  5. Enhance accessibility features and provide clear phone contact details to improve user engagement and compliance.

Technical notes

Notes

The website is built on the Webflow platform, leveraging modern front-end technologies including jQuery and iframe-lightbox for interactive content. It uses CDN services (Amazon CloudFront) for fast content delivery and Google Tag Manager for analytics and marketing integration. The site is mobile-optimized with responsive design and good SEO practices including meta tags and Open Graph data. Performance is fast with no broken elements detected. The technical infrastructure is modern and well-maintained, supporting a professional user experience. Opportunities exist to improve security headers and incident response mechanisms to reduce technical 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.
