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

TJ studio d.o.o. is a Croatian-based technology company specializing in web hosting, web design, and internet application development. Established since 2009, the company positions itself as a reliable and innovative service provider for businesses and individuals seeking professional digital solutions. Their offerings include a variety of hosting packages, domain registration, website maintenance, and custom web development services. The company maintains an active online presence with social media channels and a customer support portal, emphasizing customer service and technical support availability. Technically, the website is built on WordPress using the Betheme theme and integrates modern plugins such as Yoast SEO Premium and Slider Revolution. It employs Google Analytics for traffic analysis and Google reCAPTCHA for form security. The site is mobile-optimized and demonstrates good SEO practices. However, some security headers are not explicitly detected, and there is no dedicated security policy or incident response contact information visible. From a security perspective, the site uses HTTPS with a valid SSL certificate and implements GDPR-compliant cookie consent mechanisms. No critical vulnerabilities or exposed sensitive data were found in the HTML content. The WHOIS data is limited due to privacy protection, with no public registrant details, but the website content and contact information appear consistent and professional. Overall, TJ studio d.o.o. presents a trustworthy and professional digital presence with a solid technical foundation and compliance with privacy regulations. Strategic improvements in security headers and incident response transparency could further enhance their security posture and customer 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. 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

TJ studio d.o.o. operates in the competitive Croatian web hosting and web design market, targeting small to medium-sized businesses and individual clients. Their business model focuses on providing comprehensive digital services including hosting, domain registration, web design, and maintenance. The company leverages a customer portal for service management and offers flexible hosting packages to cater to diverse client needs. Their market positioning is that of a specialized local provider with over a decade of experience, emphasizing quality, security, and customer support. The presence of promotional campaigns and blog updates indicates active marketing and customer engagement efforts. Partnerships appear limited to internal service domains, with no external subsidiaries or parent companies identified.

Security posture

The security posture of TJ studio d.o.o. is generally good. The website enforces HTTPS and integrates Google reCAPTCHA to protect forms from automated abuse. GDPR compliance is evident through detailed privacy and cookie policies with active consent mechanisms. However, the absence of explicit HTTP security headers such as Content Security Policy (CSP), X-Frame-Options, and HSTS reduces the overall security hardening. No incident response or security contact information is publicly available, which is a gap in transparency and readiness. The use of well-known WordPress plugins and themes requires ongoing vulnerability management to mitigate risks. Overall, the site shows a mature security approach but could benefit from enhanced header policies and incident response disclosures.

Recommendations

  1. Implement comprehensive HTTP security headers including CSP, HSTS, X-Frame-Options, and X-XSS-Protection to improve security hardening.
  2. Publish a dedicated security policy and provide clear incident response contact information to enhance transparency and trust.
  3. Regularly audit and update WordPress plugins and themes to mitigate vulnerabilities and maintain platform security.
  4. Enhance accessibility features to improve compliance and user experience for all visitors.
  5. Continue monitoring GDPR compliance and update privacy practices as regulations evolve.

Technical notes

Notes

The website is built on a modern WordPress CMS platform using the Betheme theme, supported by popular plugins such as Yoast SEO Premium and Slider Revolution. It integrates Google Analytics for traffic monitoring and Google reCAPTCHA for form security. The site is mobile responsive and optimized for SEO with proper meta tags and structured data (JSON-LD). Performance is moderate, with caching and minified CSS/JS assets observed. The hosting provider is not explicitly identified but the domain registrar is Identity Digital Inc. The technical stack is standard for small to medium-sized web agencies, offering a balance of functionality and maintainability. Opportunities exist to improve security headers and accessibility compliance.
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.
