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

BestSite s.r.o. is a Czech Republic-based small business specializing in the creation of websites, e-shops, and intranet/extranet applications, with nearly 14 years of experience. The company targets businesses and organizations seeking professional web and application development services. Their key offerings include web development, e-commerce solutions, and the CMS K2 content management system. The website is professionally designed with clear navigation and branding consistent with their business identity. Technically, the website employs modern front-end technologies including Google Analytics for tracking, IAB TCF for consent management, and Nette Forms for form handling. The site is mobile optimized and uses Google Fonts for typography. However, no explicit hosting provider or server details are discernible. Performance is moderate with good SEO and accessibility basics in place. From a security perspective, the site uses cookie consent mechanisms aligned with GDPR requirements but lacks visible security headers and an explicit privacy policy page. The WHOIS data for the domain is unavailable, which raises concerns about domain legitimacy and trustworthiness. No contact emails or phone numbers are present on the site, limiting direct communication channels. Overall, the security posture is moderate but could be improved with better transparency and technical safeguards. The overall risk assessment suggests a generally trustworthy small business website with room for improvement in compliance and security transparency. Strategic recommendations include implementing security headers, publishing a privacy policy, verifying domain registration details, and providing clear contact information to enhance trust and compliance.

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. 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

      Third-party services without privacy policy

      Detected services: Google Analytics, Google APIs

      What to do: Document all third-party data sharing in your privacy policy

  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
  3. 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

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

Business profile

BestSite s.r.o. operates in the technology sector as a service provider focused on web and application development. The company appears to have a stable market position locally with nearly 14 years of operation. Their business model revolves around delivering customized web solutions including CMS-based websites, e-commerce platforms, and intranet/extranet applications. The target customer segment includes small to medium-sized businesses requiring digital presence and internal application solutions. The company leverages partnerships with technology providers such as Google for analytics and fonts. Growth indicators are not explicit but the longevity and professional presentation suggest steady operations. No parent or subsidiary relationships are evident. The company maintains a consistent brand identity and uses trust signals like cookie consent and webmaster verification tags.

Security posture

The website demonstrates a moderate security maturity level. It employs GDPR-aligned cookie consent mechanisms and uses Google Analytics with user consent. However, the absence of a privacy policy page and security headers such as Content Security Policy, HSTS, or X-Frame-Options reduces the overall security posture. The lack of visible contact information for security incidents or data protection officers indicates limited incident response readiness. No vulnerabilities or exposed sensitive data were detected in the HTML content. The missing WHOIS data for the domain is a significant compliance and trust gap. Overall, the site meets basic privacy compliance but should enhance transparency and technical security controls to improve its security culture and readiness.

Recommendations

  1. Implement and enforce security headers including CSP, HSTS, and X-Frame-Options to protect against common web attacks.
  2. Publish a comprehensive privacy policy page detailing data collection, processing, and user rights to improve GDPR compliance.
  3. Verify and publish domain registration details to enhance trust and legitimacy perception.
  4. Add clear contact information including emails and phone numbers for general and security incident communications.
  5. Regularly audit and update third-party libraries and scripts to mitigate potential vulnerabilities.

Technical notes

Notes

The website uses a modern front-end stack with Google Fonts, Google Analytics, and the IAB TCF framework for consent management. It employs the CMS K2 system for content management. JavaScript libraries such as Nette Forms and Swiper.js are used for form handling and sliders respectively. The site is mobile optimized and includes meta tags for SEO and viewport settings. Performance is moderate with no evident broken elements. However, no server-side or hosting details are available, and security headers are missing. The site could benefit from improved accessibility features and enhanced technical SEO. Overall, the technical infrastructure supports the business needs but has room for modernization and security hardening.
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.
