OKsystem a.s. · Technology · Czech Republic
Medium risk. 4 critical or high findings in GDPR outside view and SSL/TLS.
OKsystem a.s. is a well-established Czech IT company specializing in custom software development, digital transformation, and IT training services. With over 35 years of market presence and a client base exceeding 500 customers worldwide, including government and multinational corporations, the company positions itself as a trusted provider of innovative and reliable IT solutions. Their product portfolio includes custom projects, ready-made software products, and extensive training offerings. The website reflects a professional and modern digital presence with strong branding and clear navigation, targeting private companies and public administration sectors primarily in the Czech Republic. Technically, the site employs modern web standards, including HTML5, CSS3, and JavaScript, and integrates analytics and tracking tools such as Google Tag Manager and Seznam tracking. The site is mobile-optimized and accessible, with good SEO practices. Security-wise, the website enforces HTTPS and implements cookie consent mechanisms, but lacks explicit security headers and a public vulnerability disclosure program. The absence of WHOIS registration data for the domain raises concerns about domain legitimacy, which impacts overall trustworthiness despite the professional appearance and business credibility. Strategic improvements in security policies, incident response transparency, and domain registration clarity are recommended to enhance trust and compliance.
Scanned
NIS2 Art. 21(2)
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.
4 findings rated critical or high. Fix these first.
These are the privacy signals visitors and data protection authorities look for under GDPR.
GDPR requires a clear and accessible privacy policy
What to do: Add a comprehensive privacy policy page and link to it prominently
Detected services: Google Analytics, Facebook, LinkedIn, YouTube
What to do: Document all third-party data sharing in your privacy policy
TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.
Server supports weak protocols: TLSv1.1
What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions
SSL certificate uses 256-bit key, which is considered weak
What to do: Use at least 2048-bit RSA or 256-bit ECC key

Each check with its score, findings and the evidence it collected.
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
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.
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.

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.
Automated reading of the public site. Ratings are indicative.
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.
