Risk levelHigh

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

Aleš Linhart operates a small-scale web development service primarily targeting clients who want to create new websites or update existing ones. The website presents a professional image with client references and a clear service offering focused on web design and development. The technical infrastructure is basic but functional, using standard web technologies such as HTML, CSS, JavaScript, and jQuery, with Google Fonts integration. Mobile responsiveness and SEO basics are addressed, though accessibility could be improved. Security posture is moderate; HTTPS is assumed but no advanced security headers or policies are present. The absence of privacy and cookie policies, as well as contact details, limits compliance and trust. WHOIS data is unavailable, which raises concerns about domain legitimacy and transparency. Overall, the website is functional and professional but would benefit from enhanced security, compliance, and transparency measures.

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. 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 business positions itself as an independent web developer serving a Czech-speaking audience. Its competitive advantage lies in personalized service and a '4× friendly' philosophy, emphasizing user-friendly web solutions. Revenue likely derives from project-based web design and development contracts. The client references indicate a small but diverse customer base including musicians and small businesses. The lack of detailed business registration or VAT information suggests a sole proprietorship or freelancer model. Growth potential depends on expanding digital marketing and formalizing compliance and trust signals. Partnerships are limited to client references without formal alliances. The business ecosystem is lean, focusing on direct client engagement.

Security posture

The current security maturity is basic. The site uses HTTPS but lacks visible security headers such as Content-Security-Policy or X-Frame-Options. The use of an outdated jQuery version could expose the site to known vulnerabilities. No privacy or cookie policies are present, indicating GDPR compliance gaps. Incident response and security contact information are absent, reducing readiness for security events. No analytics or tracking scripts were detected, minimizing privacy risks but also limiting user behavior insights. Overall, the security posture is adequate for a small personal business but requires improvements to meet modern standards and regulatory requirements.

Recommendations

  1. Implement comprehensive privacy and cookie policies to improve GDPR compliance and user trust.
  2. Update JavaScript libraries, especially jQuery, to the latest secure versions to mitigate vulnerabilities.
  3. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  4. Provide clear contact information including email and phone to improve business credibility and facilitate incident response.
  5. Consider publishing a security policy and incident response plan to demonstrate commitment to security and compliance.

Technical notes

Notes

The website is built with standard web technologies including HTML5, CSS, and JavaScript with jQuery 1.10.2. It uses Google Fonts for typography and includes favicon and manifest files for cross-device compatibility. The site is mobile responsive and has a clear navigation structure. However, the use of an outdated jQuery version presents a security risk. No CMS or advanced frameworks are detected, indicating a custom or static site approach. Performance is moderate with no explicit optimization techniques observed. Accessibility features are basic, with room for improvement. SEO is addressed through meta tags and structured content but could be enhanced with additional semantic markup and structured data. Hosting provider and SSL certificate details are not available from the provided data.
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.
