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

David Kučera operates as a freelance graphic designer based in the Czech Republic, offering a broad range of design services including logos, corporate graphics, print materials, infographics, web design, and UX tailored to client needs. The business model is primarily freelance with the flexibility to assemble teams of specialists for larger projects. The website presents a professional portfolio with extensive references and partner collaborations, positioning the business as a credible and experienced service provider in the graphic design sector. Technically, the website is built with standard HTML5, CSS3, and JavaScript, utilizing jQuery libraries. Hosting is provided by a Czech hosting company inferred from the nameservers. The site is moderately performant with good mobile optimization and basic accessibility features. SEO is well addressed through meta tags and Open Graph data, although no CMS or advanced frameworks are detected. From a security perspective, the site lacks advanced security headers and does not provide privacy or cookie policies, which are compliance gaps. No forms or data collection mechanisms are present, reducing exposure to input-based vulnerabilities. The domain registration is consistent and transparent, supporting the legitimacy of the business. No WAF or blocking mechanisms are detected, and the content is safe for general audiences. Overall, the website is professional and trustworthy but would benefit from enhanced security practices and privacy compliance measures to improve its security posture and regulatory adherence.

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

10 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. 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

  3. 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"

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 · 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.

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 is positioned as a small freelance graphic design service provider with a strong portfolio and a network of partners offering complementary services such as web development, marketing, and photography. The target customers are businesses and individuals seeking high-quality graphic design and branding solutions. Revenue streams likely come from project-based engagements and collaborations. The partnership ecosystem enhances service offerings and market reach. The company has maintained consistent domain registration since 2015, indicating stability and growth potential. The website content and partner references reflect a mature and professional operation with a focus on quality and client satisfaction.

Security posture

The current security maturity level is basic. The website uses HTTPS (assumed but not explicitly confirmed), but lacks security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options. No privacy or cookie policies are present, indicating GDPR compliance gaps. There is no vulnerability disclosure or incident response contact information, limiting transparency in security matters. The absence of forms reduces attack surface, but also limits user interaction. Overall, the security posture is adequate for a portfolio site but requires improvements to meet modern security and privacy standards.

Recommendations

  1. Implement a comprehensive privacy policy and cookie consent mechanism to ensure GDPR compliance.
  2. Add security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  3. Establish a vulnerability disclosure policy or security.txt file to improve transparency and incident response readiness.
  4. Verify and enforce HTTPS with strong SSL/TLS configurations to secure data in transit.
  5. Include incident response contact information such as security@ or abuse@ email addresses to facilitate reporting of security issues.

Technical notes

Notes

The website is built on a simple, clean HTML5 and CSS3 foundation with JavaScript enhancements via jQuery. It does not use a CMS or advanced frameworks, which reduces complexity but may limit scalability. Hosting is provided by a Czech hosting provider, consistent with the domain's geographic focus. Performance is moderate, with no explicit optimization scripts detected. Mobile responsiveness is good, supported by viewport meta tags and responsive CSS. SEO is addressed through meta tags and Open Graph properties, enhancing social media sharing. Accessibility is basic, with room for improvement in ARIA roles and semantic markup. No analytics or tracking scripts are present, indicating minimal data collection and privacy impact.
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.
