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

Florian Karsten Studio is a small creative technology business based in Brno, Czech Republic, specializing in graphic design, UX, and development services. The studio emphasizes open-source projects, peer-to-peer networks, and automation, targeting clients interested in independent and functional digital systems. The website presents a professional portfolio with clear branding and a focus on design and technology integration. Technically, the website uses modern web technologies including HTML5, CSS, JavaScript, and libraries such as jQuery and Slick Carousel. Hosting and DNS are managed via Cloudflare and NameCheap, ensuring reliable performance and security. The site is mobile optimized and includes privacy-respecting analytics via Plausible. However, there is room for improvement in accessibility and security headers. From a security perspective, the site enforces HTTPS and uses domain transfer protection, but lacks DNSSEC and security headers which are recommended for enhanced protection. No privacy or cookie policies are present, indicating compliance gaps with GDPR and other privacy regulations. No forms or sensitive data collection mechanisms reduce risk exposure. Overall, the security posture is moderate but could be strengthened with additional policies and technical controls. The overall risk is low given the nature of the business and website content, but strategic improvements in privacy compliance and security best practices are advised to enhance trust 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

7 findings rated critical or high. Fix these first.

  1. 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';…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

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

Florian Karsten Studio operates as a niche creative and technology studio focusing on design and development services with a strong emphasis on open-source and independent web projects. The business model centers on providing bespoke digital design and programming solutions to a specialized audience. Market positioning is that of a small, agile studio with a reputation for quality and innovation in the Czech Republic. Revenue streams likely derive from client projects and possibly font licensing via the related fonts subdomain. The partnership ecosystem includes related domains such as karsten.systems and fonts.floriankarsten.com, supporting complementary services. Growth indicators include a stable domain age and consistent branding. The company maintains a lean operation without public subsidiaries or parent companies.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enabled and domain transfer protection active. However, the absence of DNSSEC and security headers such as Content-Security-Policy and X-Frame-Options represents potential vulnerabilities. No exposed sensitive data or vulnerable libraries were detected, and no forms reduce attack surface. Compliance gaps exist due to missing privacy and cookie policies, which are critical for GDPR adherence. Incident response readiness is unclear with no security contact channels provided. The security culture appears basic but responsible, with room for improvement in formalizing policies and technical defenses.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement and publish comprehensive privacy and cookie policies to improve GDPR compliance.
  3. Add security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to harden the website against common attacks.
  4. Create a security.txt file to provide clear vulnerability disclosure and incident response contact information.
  5. Consider accessibility improvements to broaden audience reach and comply with standards.

  3. Contact information limited to email and Instagram link; no phone or physical address provided.
  4. Use of modern JavaScript libraries and analytics with privacy-respecting Plausible Analytics.
  5. No forms detected on the site, limiting data collection risks.
  6. No security.txt or vulnerability disclosure policy found.

Technical notes

Notes

The website is built with a clean and modern tech stack including HTML5, CSS, JavaScript, and popular libraries like jQuery and Slick Carousel. Hosting and DNS are managed via reputable providers (Cloudflare and NameCheap). Performance is moderate with deferred script loading and optimized assets. The site is mobile responsive and SEO optimized with proper meta tags and Open Graph data. No CMS detected, indicating a custom or static site approach. Technical risks are low but could be mitigated by adding security headers and enabling DNSSEC. The absence of forms reduces complexity and security risks but limits interactive capabilities.
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.
