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

OKsystem a.s. is a well-established Czech IT company specializing in custom software development, IT services, and training with over 35 years of market presence. The company targets private firms and public administration, offering innovative, secure, and reliable software solutions. Their market position is strong, supported by a large customer base and official partnerships such as the Czech national pavilion at EXPO 2025. Technically, the website employs modern web technologies including HTML5, CSS3, JavaScript, Google Tag Manager, and reCAPTCHA, with good mobile optimization and SEO practices. Security posture is solid with HTTPS and cookie consent mechanisms, though security headers and explicit incident response policies are not evident. The absence of WHOIS data for the .com domain is a concern but may be due to privacy or alternative domain usage. Overall, the website is professional, trustworthy, and compliant with GDPR.

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

4 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.

    • 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, Facebook, LinkedIn, YouTube

      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
    • 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

  • 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 operates in the technology sector, focusing on custom IT solutions and training services. Their business model combines bespoke software projects with product offerings and educational services, serving a broad client base including public institutions and private enterprises. The company demonstrates stable growth and conservative financial management, as indicated by recent news articles. Their partnership ecosystem includes several branded product sites and training platforms, enhancing their market reach. The company maintains a strong brand presence with consistent messaging and trust signals such as certifications and client references.

Security posture

OKsystem shows a mature security posture with HTTPS enforcement, cookie consent compliance, and use of reCAPTCHA to protect forms. However, the lack of visible security headers and absence of published security policies or incident response contacts indicate areas for improvement. No vulnerabilities or exposed sensitive data were detected in the website content. GDPR compliance is evident through privacy and cookie policies. The company should consider publishing a vulnerability disclosure policy and enhancing security headers to strengthen defenses and transparency.

Recommendations

  1. Implement and verify HTTP security headers such as Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a clear terms of service page to complement privacy policies and improve legal compliance.
  3. Add explicit security policy and incident response contact information to enhance trust and preparedness.
  4. Provide clear company contact details including phone numbers and official emails on the website for better accessibility.
  5. Consider publishing a vulnerability disclosure or security.txt file to encourage responsible reporting and improve security posture.

Technical notes

Notes

The website uses a modern and standard technology stack with HTML5, CSS3, and JavaScript, including Google Tag Manager and reCAPTCHA for analytics and security. The site is mobile-optimized with responsive design and good SEO metadata. Performance is moderate with asynchronous script loading and optimized font usage. No CMS or hosting provider information is explicitly detected. The site could benefit from enhanced security headers and more explicit technical documentation to reduce technical debt and improve resilience.
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.
