74/100

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

OKsystem a.s. operates the OKbase platform, a comprehensive HR digitalization system targeting companies seeking to streamline HR processes such as attendance, payroll, personnel management, and catering. The company holds a strong market position in the Czech Republic and Slovakia with over 350 large implementations and more than 330,000 users. The website reflects a mature, professional B2B SaaS business model with additional outsourcing services. Technically, the site employs modern JavaScript frameworks, integrates multiple analytics and advertising tools, and implements GDPR-compliant cookie consent mechanisms. Security posture is solid with HTTPS and reCAPTCHA protections, though explicit security headers and policies could be improved. Overall, the site is well-designed, mobile-optimized, and trustworthy, though the absence of WHOIS data slightly reduces domain trust. Strategic recommendations include enhancing security headers, publishing security policies, and adding vulnerability disclosure information to further strengthen trust and compliance.

Scanned

3 of 7 checks could not complete. The site may be unreachable or blocking automated scans, so the results below cover only what could be checked. Try a rescan later.

NIS2 and GDPR posture

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

Priority findings

2 findings rated critical or high. Fix these first.

  1. 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 company targets HR managers and enterprises needing integrated HR solutions, offering a suite of modules including personnel management, attendance tracking, payroll, catering, and intranet services. Their competitive advantage lies in comprehensive legislative compliance, AI-driven shift planning, and extensive support services. Revenue streams likely include software subscriptions and outsourcing fees. The partnership ecosystem includes related training and quality assurance services. The company demonstrates growth through extensive client references and a large user base, positioning itself as a leading HR technology provider in its region.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, use of reCAPTCHA on forms, and a cookie consent mechanism aligned with GDPR. However, the absence of explicit security headers such as Content Security Policy (CSP), HSTS, and X-Frame-Options is a gap. No public security policy or incident response information is available, and no vulnerability disclosure or security.txt file is found, which could hinder transparency and incident handling readiness. No vulnerabilities or exposed sensitive data were detected in the content. Overall, security practices are good but could be enhanced with formal policies and headers.

Recommendations

  1. Implement and enforce security headers including CSP, HSTS, and X-Frame-Options to mitigate common web attacks.
  2. Publish a clear security policy and incident response plan accessible on the website to improve transparency and trust.
  3. Establish a vulnerability disclosure program or security.txt file to facilitate responsible reporting of security issues.
  4. Regularly audit third-party scripts and tracking tools to ensure compliance with privacy and security standards.
  5. Enhance WHOIS data availability or transparency to improve domain trustworthiness and legitimacy.

Technical notes

Notes

The website uses a modern JavaScript-based front end with asynchronous loading of analytics and tracking scripts including Google Tag Manager, Bing Ads, and Seznam tracking. It employs reCAPTCHA for form protection and has a responsive design optimized for mobile devices. The site lacks a detected CMS, suggesting a custom or proprietary platform. Performance is moderate with good SEO practices including meta tags and Open Graph data. Accessibility is good with semantic HTML and ARIA roles. Hosting provider details are not explicit. There is room for improvement in security headers and formal documentation of security practices.
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.
