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

SEKK.cz is a specialized service provider offering external quality assessment and proficiency testing services primarily for clinical laboratories in the Czech Republic. Their focus areas include biochemistry, hematology, immunology, transfusiology, allergology, and pathology. The domain has been registered since 1997, indicating a long-standing presence in the healthcare quality assessment sector. The website content is minimal but relevant to their niche, targeting clinical laboratories and healthcare professionals seeking quality evaluation services. Technically, the website uses outdated HTML frameset technology and lacks modern web development practices such as responsive design and accessibility features. There is no evidence of HTTPS enforcement or security headers, which are critical for protecting user data and ensuring secure communications. The absence of privacy, cookie, and terms of service policies indicates low digital maturity and potential compliance gaps. From a security perspective, the site shows limited security posture with no visible incident response or vulnerability disclosure mechanisms. The lack of contact information and security policies reduces trust and may impact user confidence. However, no signs of malicious content or adult material were detected, and the domain's age supports legitimacy. Overall, the site requires significant modernization and security improvements to meet current standards. Strategically, SEKK.cz should prioritize implementing HTTPS, updating the website to modern standards, and publishing clear privacy and security policies. Enhancing transparency and contactability will improve trust and compliance with GDPR and other regulations.

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

7 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

    • 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

  2. Security headers

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

SEKK operates in the healthcare sector, providing essential external quality assessment services to clinical laboratories. Their business model revolves around proficiency testing and quality assurance, which is critical for laboratory accreditation and regulatory compliance. The company targets clinical laboratories in the Czech Republic, positioning itself as a niche provider with a long operational history since 1997. The lack of visible partnerships or subsidiaries suggests a focused, possibly small-scale operation. Revenue likely derives from service fees for quality assessments. The absence of digital marketing or analytics tools indicates limited online growth initiatives. Strategic opportunities include expanding digital presence, improving user engagement, and formalizing compliance and security frameworks to enhance market competitiveness.

Security posture

The current security posture of SEKK.cz is basic and requires improvement. The absence of HTTPS and security headers exposes users to potential interception and attacks. No privacy or cookie policies are present, indicating non-compliance with GDPR and related regulations. There is no evidence of incident response contacts or vulnerability disclosure programs, which are important for managing security incidents and building trust. The use of deprecated HTML framesets may introduce technical vulnerabilities and poor user experience. While no explicit vulnerabilities or malware were detected, the site’s security maturity is low. Enhancing encryption, implementing security best practices, and establishing clear policies are critical next steps to mitigate risks and improve compliance.

Recommendations

  1. Implement HTTPS with a valid SSL/TLS certificate to secure all communications.
  2. Redesign the website using modern HTML5 and responsive design techniques to improve usability and accessibility.
  3. Publish comprehensive privacy and cookie policies to comply with GDPR and inform users.
  4. Add security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to enhance protection.
  5. Establish clear contact points for security incident reporting and vulnerability disclosure to improve trust and response readiness.

Technical notes

Notes

The website is built using legacy HTML frameset technology and PHP for content delivery. There is no indication of modern frameworks, CMS platforms, or JavaScript libraries. The meta tags include keywords and descriptions in Czech and English, supporting bilingual SEO efforts, but no Open Graph or JSON-LD structured data is present. The site lacks mobile optimization and accessibility features, which limits user experience on modern devices. No external scripts or analytics tools were detected, indicating minimal tracking or marketing integration. Hosting provider and SSL configuration details are not provided, limiting full technical assessment. Overall, the site shows signs of technical debt and would benefit from modernization to improve performance, security, and user engagement.
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.
