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

DataCentrum systems & consulting, a.s. is a Czech Republic based company specializing in outsourcing payroll and HR services, supported by proprietary software solutions for payroll, personnel information systems, and attendance management. The company targets business clients requiring comprehensive HR and payroll management solutions, positioning itself as a specialized service provider in the Czech market. The website reflects a professional and consistent brand image with clear contact information and recent updates, indicating active business operations. Technically, the website is built on WordPress with common plugins such as LayerSlider and Revolution Slider, using jQuery and Google Fonts. The site is moderately optimized for performance and mobile devices, with basic SEO and accessibility features. Security-wise, HTTPS is enabled, but there is a lack of security headers and privacy/cookie policies, which are areas for improvement. The absence of WHOIS data raises concerns about domain registration legitimacy, though the website content and contact details appear credible. Overall, the security posture is moderate with room for enhancements in compliance and security best practices. The site does not exhibit any adult or questionable content and is safe for general audiences. Strategic recommendations include adding privacy and cookie policies, implementing security headers, verifying domain registration status, and maintaining up-to-date software to mitigate vulnerabilities.

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

11 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

      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

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

DataCentrum operates in the technology sector focusing on HR and payroll outsourcing services, leveraging proprietary software solutions. Its business model is B2B, serving medium-sized enterprises and organizations in the Czech Republic. The company’s competitive advantage lies in integrated software and consulting services tailored to payroll and HR needs. Revenue streams likely include software licensing, outsourcing contracts, and consulting fees. The website indicates active engagement with clients through news updates and support links. No direct partnerships or subsidiaries are evident from the website content. The company maintains a professional online presence with consistent branding and trust signals such as contact transparency and recent content.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enabled, ensuring encrypted communications. However, the absence of key security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security reduces defense-in-depth. No explicit vulnerabilities or exposed sensitive data were detected in the content. The lack of privacy and cookie policies indicates compliance gaps with GDPR and related regulations. Incident response and security policy information are not publicly available, suggesting limited transparency in security governance. The presence of tracking scripts without clear privacy disclosures further impacts privacy compliance. Overall, the security posture is functional but requires enhancements to meet best practices and regulatory requirements.

Recommendations

  1. Implement comprehensive privacy and cookie policies to ensure GDPR compliance and user transparency.
  2. Add essential security headers (CSP, X-Frame-Options, HSTS, X-Content-Type-Options) to strengthen security posture.
  3. Verify and update domain registration details to ensure legitimacy and avoid potential domain expiry or privacy concerns.
  4. Regularly update WordPress core and plugins to mitigate vulnerabilities and maintain platform security.
  5. Enhance incident response readiness by publishing security policies and contact channels for security issues.

Technical notes

Notes

The website is built on WordPress 4.8.27 with jQuery 1.12.4 and uses popular slider plugins (LayerSlider, Revolution Slider). Google Fonts and FontAwesome are used for typography and icons. The site loads external resources from trusted domains such as fonts.googleapis.com and ajax.googleapis.com. Performance is moderate with some optimization potential, especially for mobile responsiveness and accessibility. No advanced frameworks beyond WordPress were detected. The hosting provider is not explicitly identified. The site uses HTTPS, but lacks modern security headers. Tracking scripts from Leady indicate some marketing integration. Overall, the technical infrastructure is standard for a business website but could benefit from modernization and enhanced 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.
