54/100

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

Centrum Czech in is a small educational organization based in the Czech Republic specializing in Czech language courses for adults and children. The website is professionally designed using WordPress with modern SEO practices and social media integration. The technical infrastructure includes common plugins and Google Analytics for tracking. Security posture is adequate with HTTPS enabled but lacks advanced security headers and formal policies. Privacy compliance is weak due to missing privacy and cookie policies. Overall, the site is trustworthy and serves its niche audience effectively but should improve compliance and security transparency.

Scanned

3 of 7 checks could not complete. The site may be unreachable or blocking automated scans, so the results below cover only what could be checked. Try a rescan later.

NIS2 and GDPR posture

GDPR outside view
Not assessed

Both readouts depend on the site's pages, which could not be loaded in this scan.

Priority findings

3 findings rated critical or high. Fix these first.

  1. 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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  2. 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.

    • High

      No DMARC record found

      DMARC provides email authentication and reporting

      What to do: Add DMARC record: "v=DMARC1; p=none; rua=mailto:dmarc@yourdomain.com"

  3. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • High

      No Name Servers Found

      Unable to find name servers for domain

      What to do: Configure proper name servers for the domain

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

  • Security headers: did not complete in this scan.
  • GDPR outside view: did not complete in this scan.
  • 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 organization targets foreigners and learners of Czech language, offering group and individual courses at competitive prices. The business model is service-based education with a focus on language integration. The website supports the business with clear contact info and social media presence. Partnerships such as with p-p-i.cz indicate collaboration within the integration and education sector. Growth potential exists with improved digital maturity and compliance.

Security posture

The website uses HTTPS and avoids exposing sensitive data. However, it lacks security headers and formal security or incident response policies. No vulnerability disclosure or security.txt files are present. The use of third-party scripts is minimal and standard. Privacy compliance gaps pose risks under GDPR. Overall security maturity is moderate but can be enhanced with policy transparency and technical hardening.

Recommendations

  1. Publish a comprehensive privacy policy and cookie policy with GDPR compliance details.
  2. Implement cookie consent mechanisms to inform users about tracking.
  3. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Create and publish a vulnerability disclosure or security incident response policy.
  5. Regularly audit and update plugins and scripts to mitigate vulnerabilities.

Technical notes

Notes

The website is built on WordPress 6.8.2 with Yoast SEO and Colibri Page Builder Pro, indicating a modern CMS environment. It uses jQuery and Google Analytics for functionality and tracking. The site is mobile responsive and SEO optimized with structured data. Hosting details are limited but use muj.cloud name servers. Performance is moderate with caching and minified CSS. Accessibility is basic but could be improved. No critical technical debt or risks detected.
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.
