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

YouCan.cz is a Czech-based professional web development team specializing in creating websites, e-commerce platforms, and custom web applications tailored to client needs. Their portfolio includes diverse clients such as municipalities, internet providers, schools, and e-commerce businesses, positioning them as a regional technology service provider. The website content is well-structured and professional, targeting businesses seeking reliable web solutions. Technically, the site uses legacy JavaScript libraries like jQuery 1.4.2 and Coin Slider, alongside Google Analytics and Mouseflow for user behavior tracking. While the site is accessible and well-organized, it lacks modern security headers and visible HTTPS confirmation, and the outdated libraries pose potential security risks. Mobile optimization is basic, and no CMS or hosting provider details are evident. From a security perspective, the absence of privacy, cookie, and terms policies, combined with missing WHOIS registration data, reduces trustworthiness. The site does not exhibit signs of WAF or blocking mechanisms, but the lack of updated security practices and policies indicates room for improvement. Tracking scripts are present without visible consent mechanisms, raising privacy compliance concerns. Overall, the website is functional and professional but requires updates in security, privacy compliance, and technical modernization to enhance trust and resilience. The missing WHOIS data is a notable risk factor, and implementing HTTPS and security headers is strongly recommended.

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

12 findings rated critical or high. Fix these first.

  1. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection
    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

  3. 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

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

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 · found on this site
  • 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.

Business context

Business profile

YouCan.cz operates as a small-sized technology service provider focused on web development and e-commerce solutions in the Czech Republic. Their business model centers on custom project delivery with a diverse client base including public institutions and commercial entities. The company leverages client references and a portfolio of partner sites to establish credibility. Revenue streams likely derive from project-based contracts and ongoing web maintenance. The presence of social media engagement via Facebook indicates active customer interaction. Growth indicators include a broad client portfolio and multi-year web presence, though domain registration opacity may hinder trust. Strategic partnerships with various client domains suggest a collaborative ecosystem supporting their market position.

Security posture

The current security posture of YouCan.cz is moderate but with notable gaps. The use of outdated JavaScript libraries such as jQuery 1.4.2 introduces potential vulnerabilities. There is no evidence of HTTPS enforcement or modern security headers like Content-Security-Policy or X-Frame-Options, which are critical for mitigating common web attacks. The absence of privacy and cookie policies, along with no visible incident response or security contact information, indicates limited compliance with GDPR and other data protection regulations. Tracking technologies are implemented without clear consent mechanisms, posing privacy risks. The missing WHOIS data further reduces domain trust and raises questions about registration legitimacy. Overall, the site requires significant improvements in security best practices and compliance to reduce risk exposure.

Recommendations

  1. Upgrade all JavaScript libraries, especially jQuery, to current secure versions to mitigate known vulnerabilities.
  2. Implement HTTPS with a valid SSL/TLS certificate and enforce secure connections site-wide.
  3. Add essential security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common attacks.
  4. Publish comprehensive privacy and cookie policies with clear GDPR compliance statements and implement user consent mechanisms for tracking technologies.
  5. Resolve WHOIS data issues by ensuring domain registration information is complete and publicly accessible to improve domain trustworthiness.

Technical notes

Notes

The website employs legacy technologies including jQuery 1.4.2 and Coin Slider, which may impact security and performance. Google Analytics and Mouseflow are used for analytics and user behavior tracking, but without visible privacy controls. The site lacks a detectable CMS and hosting provider information. Performance is moderate with basic mobile optimization and accessibility features. Meta tags for SEO are present but limited. The HTML structure is valid and well-formed, supporting good user experience. However, the absence of HTTPS confirmation and security headers indicates technical debt and modernization opportunities. Addressing these technical risks will improve operational stability and security posture.
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.
