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

SEKK.cz is a website dedicated to providing external quality assessment and proficiency testing services primarily for clinical laboratories in the Czech Republic. The business focuses on various laboratory disciplines including biochemistry, hematology, immunology, transfusiology, allergology, and pathology. Established since 1997, the domain age supports the legitimacy and longstanding presence of the organization in the healthcare quality assessment sector. The website content is bilingual (Czech and English) and targets clinical laboratories and healthcare professionals seeking quality assurance services. Technically, the website uses legacy HTML framesets and PHP, indicating an outdated infrastructure with limited modern web technologies or mobile optimization. Security posture is weak due to lack of HTTPS, security headers, and absence of privacy or cookie policies, which also impacts GDPR compliance. No contact information or forms are present in the analyzed content, limiting user engagement and trust signals. Overall, the site is functional but requires modernization and improved security and privacy practices to meet current standards.

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

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

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 healthcare sector, specifically focusing on laboratory quality assurance services. Its business model revolves around providing external quality assessment and proficiency testing to clinical laboratories, which is a niche but essential service for healthcare compliance and accreditation. The domain's long registration history suggests stability and market presence. However, the website lacks modern digital marketing and engagement tools such as analytics, social media integration, or advertising. The absence of contact details and policies may hinder customer trust and limit growth potential. There is no evidence of partnerships or subsidiaries from the provided data. The company likely targets small to medium-sized clinical laboratories within the Czech Republic and possibly neighboring regions.

Security posture

The website currently exhibits a low security maturity level. The absence of HTTPS is a critical vulnerability that exposes users to data interception risks. No security headers or incident response contacts are provided, indicating a lack of formal security policies or frameworks. There is no evidence of GDPR compliance mechanisms such as privacy or cookie policies, which is a significant compliance gap given the European jurisdiction. The lack of forms reduces attack surface but also limits user interaction. Overall, the security posture is weak and requires urgent improvements to protect user data and comply with regulations.

Recommendations

  1. Implement HTTPS across the entire website to secure data transmission and improve user trust.
  2. Develop and publish comprehensive privacy and cookie policies to comply with GDPR and inform users.
  3. Add clear contact information including emails and phone numbers to enhance credibility and support.
  4. Modernize the website's technical infrastructure by replacing framesets with responsive HTML5 and CSS.
  5. Introduce security headers and an incident response contact to improve security posture and readiness.

Technical notes

Notes

The website uses outdated HTML frameset technology combined with PHP for content delivery, which negatively impacts user experience, SEO, and mobile responsiveness. No modern JavaScript frameworks, analytics, or CMS platforms are detected. The site lacks HTTPS, security headers, and accessibility features. Performance is likely moderate due to simple static content but could be improved with modernization. The absence of meta Open Graph or JSON-LD structured data limits SEO and social media integration. Overall, the technical implementation is basic and requires significant updates to meet current web standards and security best 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.
