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

Checkbot is a specialized software solution developed by OKsystem a.s. for real-time monitoring and management of Yaskawa industrial robots. The platform offers comprehensive features including remote access, automated backups, predictive maintenance, alarm notifications, and detailed analytics, targeting manufacturing and automation professionals. The company maintains strong partnerships with major industrial players and emphasizes continuous improvement and security compliance. The website is professionally designed, mobile-optimized, and provides extensive client references and support resources. However, the absence of WHOIS registration data for the domain www.checkbot.com raises concerns about domain legitimacy that should be addressed. The technical infrastructure leverages modern web technologies, Google Analytics, and reCAPTCHA for security and user tracking, with GDPR-compliant privacy and cookie policies in place. Security posture is solid with HTTPS and penetration testing mentioned, but could be improved by adding explicit security headers and incident response disclosures.

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. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

    • High

      No SPF record found

      SPF helps prevent email spoofing

      What to do: Add SPF record: "v=spf1 include:_spf.yourmailprovider.com ~all"

  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.

Add-on

Leaked records that mention checkbot.cz, from OffSeq Breach.

No leaked records found

Breach holds no records for checkbot.cz right now. New leaks arrive continuously, so monitoring on Breach alerts you if that changes.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

OKsystem a.s. operates in the manufacturing sector, providing software tools for industrial automation monitoring. Their Checkbot product is positioned as a reliable, efficient solution with a SaaS subscription model, serving a global client base including automotive, construction, and machinery manufacturers. The company benefits from ISO certifications and a strong brand presence in the Czech Republic and internationally. Their business model focuses on long-term client relationships supported by continuous updates, training, and customer support. The partnership with Yaskawa and other industrial leaders enhances market credibility. Growth indicators include recent news updates and expanding client testimonials. The company maintains a professional online presence with clear contact channels and marketing efforts through newsletters and social media.

Security posture

The website demonstrates a mature security posture with HTTPS enforcement, reCAPTCHA integration, and a cookie consent mechanism aligned with GDPR requirements. The company performs regular penetration testing and maintains ISO/IEC 27001 certification, indicating a commitment to information security management. However, the lack of visible security headers such as Content Security Policy (CSP), HSTS, and X-Frame-Options is a gap that could expose the site to certain web-based attacks. No explicit incident response or vulnerability disclosure policies are published, which limits transparency and readiness communication. Data storage is primarily on-premise, enhancing data control. Overall, the security measures are robust but could be enhanced with additional headers and public security policies.

Recommendations

  1. Implement and publish a comprehensive incident response and vulnerability disclosure policy to improve transparency and security readiness.
  2. Add standard security headers (CSP, HSTS, X-Frame-Options) to the web server configuration to mitigate common web vulnerabilities.
  3. Verify and update WHOIS domain registration information to ensure domain legitimacy and trust.
  4. Provide explicit contact information for a Data Protection Officer or privacy contact to strengthen GDPR compliance.
  5. Consider publishing data retention policies and security practices in more detail to enhance user trust and compliance.

Technical notes

Notes

The website uses modern web technologies including asynchronous JavaScript, Google Tag Manager, and reCAPTCHA for security and analytics. The design is responsive and optimized for mobile devices, with good SEO practices such as meta tags and Open Graph data. The site supports PostgreSQL as a backend database. Performance is fast with efficient loading of multimedia content. No CMS was detected, suggesting a custom or static site architecture. The absence of explicit security headers is a technical shortcoming. Hosting provider details are not disclosed. Overall, the technical implementation is solid with room for security enhancements and improved domain registration transparency.
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.
