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

Vojtěch Nedvěd operates a professional web development service primarily focused on creating websites and e-shops for a variety of clients. The business is positioned as a small independent developer based in the Czech Republic, with a portfolio showcasing diverse projects including programming, coding, design, and copywriting services. The website is well-structured, visually consistent, and targets local Czech businesses and individuals seeking custom web solutions. Technically, the site employs modern web standards including HTML5, CSS3, JavaScript, and integrates Google Fonts and Font Awesome for styling. It uses Google Analytics and Tag Manager for visitor tracking, hosted on Wedos, a reputable Czech hosting provider. The site is mobile optimized and SEO friendly but lacks advanced accessibility features. Security posture is solid with HTTPS enabled and no visible vulnerabilities, though security headers are missing and no formal security or privacy policies are published. Contact information is clearly presented, enhancing business credibility. Overall, the site is functional and professional but would benefit from improved privacy compliance and security best practices.

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

9 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 operates in the technology sector as a small-scale web development service provider. Its competitive advantage lies in personalized service and a broad skill set covering web programming, e-commerce solutions, design, and copywriting. Revenue likely derives from project-based contracts for website and e-shop creation. The target market includes small to medium businesses and individuals in the Czech Republic. The company has maintained consistent domain registration since 2015, indicating stable operations. The portfolio references and direct contact details support trustworthiness. No parent or subsidiary companies are identified, suggesting an independent operation. The absence of formal privacy and security policies may limit appeal to larger corporate clients or regulated industries. Strategic partnerships are not evident from the data.

Security posture

The website demonstrates a moderate to good security posture with mandatory HTTPS encryption and no visible exposure of sensitive data. However, the absence of security headers such as Content-Security-Policy and X-Frame-Options reduces defense-in-depth. No vulnerability disclosure or incident response information is provided, which could hinder timely reporting and mitigation of security issues. The use of third-party scripts like Google Analytics introduces tracking but lacks user consent mechanisms, raising privacy compliance concerns under GDPR. No forms are present, minimizing attack surface from input vectors. Overall, the security maturity is adequate for a small business but requires enhancements in policy transparency and technical controls to meet higher compliance standards.

Recommendations

  1. Implement and publish a comprehensive privacy policy and cookie consent mechanism to improve GDPR compliance.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  3. Create a security.txt file or equivalent vulnerability disclosure policy to facilitate responsible reporting of security issues.
  4. Regularly review and update third-party scripts and dependencies to mitigate risks from vulnerable libraries.
  5. Enhance website accessibility features to improve usability for all users and comply with accessibility standards.

Technical notes

Notes

The website is built using standard web technologies including HTML5, CSS3, and JavaScript with jQuery. It leverages Google Fonts and Font Awesome for typography and icons. Analytics are implemented via Google Analytics and Google Tag Manager, indicating a moderate level of digital maturity in tracking user behavior. Hosting is provided by Wedos, a known Czech hosting provider, consistent with the domain registrar. The site is mobile responsive and SEO optimized with appropriate meta tags. No CMS or advanced frameworks are detected, suggesting a custom-coded site. Performance is moderate with asynchronous loading of analytics scripts. No forms or complex interactive elements reduce technical complexity and potential vulnerabilities. Opportunities exist to improve accessibility and implement modern security headers to reduce technical risks.
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.
