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

kestolu.cz is a Czech-based software solution specializing in providing an integrated e-shop module for the ABX Harsys gastro program. The company, ABX software s.r.o., founded in 2021, targets restaurants and gastro businesses seeking seamless online ordering and payment integration. The website offers demos, customer references, and detailed feature descriptions, positioning itself as a niche player in the hospitality technology sector. Technically, the site uses modern frontend libraries such as Bootstrap, FontAwesome, and Swiper.js, with responsive design and moderate performance. However, it lacks visible backend CMS indicators and advanced SEO or accessibility features. Security posture is moderate with HTTPS implied but missing explicit security headers and privacy policies, indicating compliance gaps. Contact information is clearly provided, enhancing business credibility. Overall, the site is professional and functional but would benefit from improved privacy compliance and security hardening.

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.

Priority findings

12 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

  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

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 business operates a SaaS model offering monthly and annual subscriptions for e-shop modules integrated with the Harsys POS system. Its competitive advantage lies in deep integration with a popular Czech gastro software, enabling streamlined order management and payment processing via GoPay. The target customers are small to medium-sized restaurants using Harsys software. The presence of multiple demo sites and customer references suggests active client engagement and market traction. The company maintains a focused partnership ecosystem including ABX software and GoPay, reinforcing its market position. Growth potential exists through feature expansion and enhanced compliance. The business model is straightforward, relying on software licensing and support services.

Security posture

The website demonstrates a basic to moderate security maturity level. HTTPS is used, but no security headers such as Content Security Policy or HSTS are detected. There are no visible forms collecting sensitive data on the main page, reducing immediate risk exposure. However, the absence of privacy and cookie policies indicates GDPR compliance gaps. No incident response or vulnerability disclosure information is provided, limiting transparency. The site does not appear to use tracking or analytics scripts, which reduces privacy risks but also limits user behavior insights. Overall, the security posture is adequate for a marketing site but requires improvements to meet best practices and regulatory requirements.

Recommendations

  1. Implement and publish a comprehensive privacy policy and cookie policy to ensure GDPR compliance.
  2. Add a cookie consent mechanism to inform users and obtain consent for tracking or cookies.
  3. Configure and deploy security headers such as Content Security Policy, HSTS, X-Frame-Options, and X-Content-Type-Options.
  4. Establish and publish an incident response contact or security@ email address for vulnerability reporting.
  5. Conduct a security audit of all frontend and backend components to identify and remediate potential vulnerabilities.

Technical notes

Notes

The website is built using modern frontend technologies including Bootstrap for responsive design, FontAwesome for icons, Google Fonts for typography, and Swiper.js for interactive sliders. The site loads additional scripts like PureCounter for animated counters and Iconify for icons. The HTML is well-structured with semantic sections and navigation. However, no CMS or backend platform is evident from the source. Hosting provider details are not explicitly disclosed but the domain uses Czech-based name servers consistent with the business location. Performance is moderate with no obvious blocking scripts or heavy resources. Mobile optimization is good, but accessibility features are basic. SEO is supported by meta tags but lacks advanced structured data or Open Graph tags. Overall, the technical implementation is solid but could be enhanced with better SEO, accessibility, and security configurations.
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.
