DLK Studio is a Czech-based small technology company specializing in custom web development, design, 3D modeling, and digital marketing services. Founded recently in 2023, the company positions itself as a creative and innovative studio focused on delivering bespoke digital solutions tailored to individual client needs. Their website is professionally designed, multilingual (Czech and English), and showcases a portfolio of completed projects, indicating a client-focused approach and timely delivery. Technically, the website is built on WordPress using the Woodmart theme and Elementor page builder, enhanced with SEO and translation plugins such as Yoast SEO and Weglot. The site demonstrates good mobile optimization and moderate performance. Hosting and domain registration are consistent with the Czech market, using Active24 as registrar and likely hosting provider. From a security perspective, the site uses HTTPS with a good SSL configuration but lacks explicit security headers and documented security policies. No vulnerability disclosure or incident response information is provided, which could be improved. Cookie consent is implemented, indicating some level of privacy compliance. Contact information is clearly presented, enhancing business credibility. Overall, the website presents a trustworthy and professional digital presence suitable for a small creative technology business. Strategic improvements in security policies and compliance documentation would enhance their security posture and client trust.

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

  2. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  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"

    • 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

DLK Studio operates in the technology sector, focusing on custom web and application development, 3D modeling, and digital marketing. Their business model is service-oriented, targeting businesses and individuals seeking tailored digital solutions. The company leverages modern web technologies and maintains a multilingual website to broaden market reach. Their portfolio and client-centric approach suggest a competitive advantage in delivering personalized services. The absence of parent or subsidiary companies indicates an independent operation. Social media engagement on Facebook and Telegram supports marketing efforts. Growth indicators include recent domain registration and active content updates. No direct partnerships or payment processors were identified from the website content.

Security posture

The website demonstrates a basic to moderate security maturity level. HTTPS is enforced with a valid SSL certificate, ensuring encrypted communication. However, the absence of security headers such as Content Security Policy (CSP), HSTS, and X-Frame-Options reduces protection against common web attacks. No explicit security or incident response policies are published, and no dedicated security contact channels are provided. The use of reputable WordPress plugins and regular updates is assumed but not verified. No vulnerabilities or exposed sensitive data were detected in the HTML content. GDPR compliance is partially indicated by the presence of a privacy policy and cookie consent mechanism. Overall, the security posture is adequate for a small business but could benefit from enhanced policies and technical controls.

Recommendations

  1. Implement comprehensive security headers (CSP, HSTS, X-Frame-Options, X-XSS-Protection) to strengthen web security.
  2. Publish a clear security policy and incident response plan on the website to improve transparency and preparedness.
  3. Establish a vulnerability disclosure program or security.txt file to encourage responsible reporting of security issues.
  4. Regularly audit and update WordPress core, themes, and plugins to mitigate risks from known vulnerabilities.
  5. Enhance privacy compliance by detailing data retention policies and appointing a Data Protection Officer if applicable.

Technical notes

Notes

The website is built on a modern WordPress CMS platform using the Woodmart theme and Elementor page builder, which provides flexibility and ease of content management. The tech stack includes popular libraries such as jQuery, Bootstrap, Swiper.js for carousels, and Photoswipe for image galleries. SEO is enhanced via the Yoast SEO plugin, and multilingual support is provided by Weglot. The site loads external resources from trusted CDNs like Google Fonts and Weglot. Performance is moderate, with some lazy loading and prefetching optimizations. Mobile responsiveness is good, and accessibility features are basic but present. Technical risks include potential plugin vulnerabilities and lack of advanced security headers. Opportunities exist to improve performance and security hardening.
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.
