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

NetSystems Solution s.r.o. is a Czech-based digital agency specializing in the creation of modern responsive websites, e-commerce platforms, online marketing, and hosting services. With over 15 years of experience and more than 1500 projects completed, the company positions itself as a trusted partner for businesses seeking comprehensive digital solutions. Their proprietary CMS and e-shop platform underline their technical capabilities and commitment to tailored client solutions. The website is professionally designed, mobile-optimized, and provides clear navigation and contact information, targeting business clients primarily in the Czech Republic. Technically, the website employs standard modern web technologies including HTML5, CSS3, JavaScript, and jQuery, with Google Tag Manager integrated for analytics and marketing tracking. The site uses HTTPS with excellent SSL configuration, ensuring secure communications. However, the absence of security headers and a published privacy policy indicates room for improvement in security and compliance maturity. The cookie consent mechanism is implemented, reflecting some GDPR awareness. From a security perspective, the site shows a moderate security posture with no visible vulnerabilities or exposed sensitive data. The lack of incident response contact details and vulnerability disclosure policies suggests limited readiness for security incidents. WHOIS data is unavailable, which reduces transparency but does not directly indicate malicious intent. Overall, the site is safe, professional, and trustworthy, but could enhance its compliance and security posture. Strategically, the company should prioritize publishing a comprehensive privacy policy, implementing security headers, and establishing clear incident response channels to improve trust and compliance. Enhancing accessibility and SEO further would support broader market reach and user experience.

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

8 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

      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

  2. Security headers

    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

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

NetSystems operates as a small-sized technology company focused on digital agency services including web development, e-commerce solutions, online marketing campaigns, custom system development, email marketing, and hosting. Their competitive advantage lies in their proprietary platforms and long-standing market presence in the Czech Republic. The business model is service-oriented, targeting SMEs and enterprises needing tailored digital solutions. Revenue streams likely include project-based fees, hosting subscriptions, and marketing services. The company demonstrates growth through a large portfolio of completed projects and a diverse client base. Partnerships or subsidiaries are not evident from the data. The company maintains a professional online presence with consistent branding and client references, supporting credibility and market positioning.

Security posture

The website enforces HTTPS with strong SSL configuration, which is a fundamental security measure. However, the absence of common security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options reduces protection against common web attacks like clickjacking and MIME sniffing. No evidence of exposed sensitive data or vulnerable libraries was found. The cookie consent banner indicates some level of privacy compliance, but the lack of a privacy policy and incident response information highlights compliance gaps, particularly regarding GDPR and NIS2 requirements. The site does not publish a security.txt or vulnerability disclosure policy, limiting transparency and user trust in security practices. Overall, the security posture is moderate but could be significantly improved with standard best practices and compliance documentation.

Recommendations

  1. Publish a comprehensive privacy policy page detailing data collection, processing, and user rights to ensure GDPR compliance.
  2. Implement essential security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web vulnerabilities.
  3. Establish and publicize an incident response contact or page to improve transparency and readiness for security events.
  4. Create and maintain a vulnerability disclosure policy or security.txt file to encourage responsible reporting and demonstrate security commitment.
  5. Enhance website accessibility features to comply with standards and improve user experience for all visitors.

Technical notes

Notes

The website is built using standard web technologies including HTML5, CSS3, JavaScript, and jQuery, with Google Tag Manager integrated for analytics and marketing. It uses a proprietary CMS developed by NetSystems, indicating in-house technical capabilities. The site is mobile-optimized and has good SEO practices with proper meta tags and structured navigation. Performance is moderate, with no major issues detected. However, the lack of security headers and limited accessibility features suggest areas for technical improvement. Hosting provider details are not disclosed. Overall, the technical infrastructure supports the business needs but could benefit from modernization in security and accessibility domains.
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.
