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

E4YOU spol. s r.o. is a Czech technology company established in 2000 specializing in developing mobile marketing systems, CRM intranets and extranets, school intranets, web design, SEO, hosting, and technical support services. The company targets businesses requiring comprehensive marketing and IT solutions, offering tailored software and hosting services. Their market position is supported by a long domain history and a client base including reputable international brands. Technically, the website uses modern JavaScript libraries, Google Analytics with consent management via Cookiebot, and demonstrates good mobile optimization and SEO practices. However, security posture is moderate due to lack of visible security headers and published security policies. Privacy compliance is partial with cookie consent but no privacy or terms policies found. Overall, the site is professional and trustworthy with clear contact information and business legitimacy. Strategic improvements in security headers, privacy documentation, and incident response disclosures are 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

8 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

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  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

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.

Breach exposure

Leaked credentials and lookalike domains from OffSeq Breach. The counts are free; the detailed lists are paid add-ons.

Dark web exposure

Add-on

Leaked records that mention e4you.cz, from OffSeq Breach.

No leaked records found

Breach holds no records for e4you.cz right now. New leaks arrive continuously, so monitoring on Breach alerts you if that changes.

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 B2B technology sector, providing software and IT services focused on marketing systems, CRM, and web solutions. Their competitive advantage lies in long-term market presence, customized solutions, and a strong client portfolio. Revenue streams likely include software licensing, hosting fees, and support contracts. Target customers are businesses needing marketing and IT infrastructure. The partnership ecosystem is not explicitly detailed but includes notable clients. Growth indicators include continuous service offerings since 2000 and multiple service lines. The company maintains a professional online presence with consistent branding and clear contact channels.

Security posture

The website demonstrates a moderate security maturity level. It employs cookie consent management and respects user privacy with Google Analytics configured for consent. However, no security headers such as CSP, HSTS, or X-Frame-Options are detected, and no security or incident response policies are published. There is no evidence of vulnerability disclosure or security.txt files. The absence of HTTPS enforcement details and secure form handling reduces the security posture score. Business impact of these gaps includes potential exposure to common web attacks and reduced user trust. Compliance with GDPR is partial due to missing privacy policy. Incident response readiness is unclear. Security culture indicators are limited to cookie consent implementation.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a clear privacy policy and terms of service to improve GDPR compliance and user trust.
  3. Establish and disclose a security policy and incident response contact information to enhance transparency and readiness.
  4. Authorize the domain in Cookiebot Manager to properly display cookie declarations and improve consent transparency.
  5. Conduct a security audit to identify and remediate any vulnerabilities and improve secure form handling and HTTPS enforcement.

Technical notes

Notes

The website uses standard HTML5 with UTF-8 charset and responsive meta viewport settings. JavaScript libraries include Google Analytics (gtag.js) and Cookiebot scripts for consent management. The site loads asynchronously for performance. No CMS or frameworks are explicitly detected. Hosting provider details are not disclosed. Performance is moderate with good mobile optimization and basic accessibility features. SEO is supported by meta tags and Open Graph properties. The site lacks advanced accessibility features and security headers. Technical debt is moderate with opportunities for modernization in security and privacy compliance. No critical technical risks are evident but improvements are recommended to enhance security and compliance 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.
