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

The website trzistepodkastany.cz represents a local marketplace called "Tržiště Pod Kaštany" located in Zlín, Czech Republic. It focuses on offering a diverse range of regional food products and hosting community events that foster direct interaction between sellers and buyers. The business model is centered around a physical and digital marketplace promoting local and healthy food options, targeting local residents and tourists. The website content is well-structured, with clear navigation and a consistent brand presence, supported by social media channels on Facebook and Instagram. From a technical perspective, the site employs a variety of modern JavaScript libraries and plugins such as jQuery, fullcalendar, select2, and Google services including reCAPTCHA and Tag Manager. The site enforces HTTPS and includes a Content-Security-Policy header, indicating a baseline security posture. Performance and mobile optimization are adequate, though accessibility features could be improved. SEO is supported by proper meta tags and Open Graph data. Security-wise, the website benefits from HTTPS and basic security headers but lacks comprehensive security policies such as privacy, cookie, or vulnerability disclosure statements. No critical vulnerabilities or exposed sensitive data were detected. The absence of privacy and cookie policies represents a compliance gap, especially under GDPR regulations. Contact information is clearly provided, enhancing business credibility. Overall, trzistepodkastany.cz is a legitimate, small-scale local marketplace website with good content quality and technical implementation. To improve security posture and compliance, it is recommended to implement privacy and cookie policies, enhance security headers, and consider a vulnerability disclosure mechanism. These steps will strengthen trust and regulatory adherence while maintaining a positive user experience.

Both readouts depend on the site's pages, which could not be loaded in this scan.

Priority findings

3 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

  2. 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

  • Security headers: did not complete in this scan.
  • GDPR outside view: did not complete in this scan.
  • 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 business operates as a local marketplace specializing in regional and healthy food products in the Zlín region of the Czech Republic. Its competitive advantage lies in fostering direct seller-buyer relationships and hosting community events that enhance customer engagement. The business model is primarily retail-focused with an emphasis on local sourcing and quality. Revenue streams likely include vendor fees and event participation. The target customer segment includes local residents and tourists interested in regional products. The website's partnership ecosystem includes social media platforms for marketing and Google services for analytics and security. Growth indicators include a recent domain registration in 2022 and active social media presence. Strategic observations suggest opportunities to expand digital presence and improve compliance to enhance market trust.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and a Content-Security-Policy header in place. Google reCAPTCHA is used to protect forms from automated abuse. However, the absence of additional security headers such as X-Frame-Options and X-Content-Type-Options limits protection against clickjacking and MIME sniffing attacks. No vulnerability disclosure or incident response policies are visible, which could hinder timely security issue reporting and resolution. GDPR compliance is incomplete due to missing privacy and cookie policies. Data protection practices appear basic, with no exposed sensitive data detected. Incident response readiness and security culture indicators are not evident from the site content. Overall, the security posture is adequate for a small local business but requires enhancements to meet best practices and regulatory requirements.

Recommendations

  1. Implement a comprehensive privacy policy and make it easily accessible on the website.
  2. Add a cookie policy and consent mechanism to comply with GDPR and enhance user transparency.
  3. Enhance security headers by adding X-Frame-Options, X-Content-Type-Options, and Referrer-Policy.
  4. Establish a vulnerability disclosure policy and consider publishing a security.txt file.
  5. Improve accessibility features to meet recognized standards and broaden user inclusivity.

Technical notes

Notes

The website uses a broad set of JavaScript libraries and plugins to deliver interactive features such as calendars, modals, sliders, and media players. Google Fonts and Google Tag Manager are integrated for typography and analytics respectively. The site enforces HTTPS and includes a Content-Security-Policy header to upgrade insecure requests. Performance is moderate, with potential optimization opportunities in script loading and caching. Mobile responsiveness is good, ensuring usability across devices. The absence of a detected CMS suggests a custom or lightweight platform. Hosting provider details are not explicit. Technical risks include reliance on multiple third-party libraries which require regular updates to mitigate vulnerabilities. Modernization opportunities include adopting progressive web app features and improving accessibility compliance.
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.
