Security score

42/100

Risk levelHigh

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

CORE d.o.o. operates the Catapult Trading Platform, a customizable electronic trading software solution targeting brokerage firms and traders. The platform emphasizes modular architecture, multi-device accessibility, and extensibility with brokerage-specific add-ons. The company is positioned as a niche provider in the finance technology sector with a focus on delivering tailored trading infrastructure. Technically, the website uses standard HTML5, CSS, and jQuery, but lacks modern security practices such as HTTPS and security headers. The site is functional with good content quality but limited privacy and compliance features. Security posture is weak due to missing HTTPS and insecure external resource loading. Overall, the domain registration data supports the legitimacy and longevity of the business. Strategic improvements in security and privacy compliance are recommended to enhance trust and protect user data.

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

  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"

    • 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 · 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 company targets financial institutions and traders requiring bespoke electronic trading solutions. Its modular platform allows clients to tailor trading environments, providing competitive advantages in flexibility and extensibility. Revenue likely derives from software licensing and service contracts. The absence of direct contact details and limited marketing tools suggests a focused B2B approach. The company maintains a consistent brand identity but could improve transparency with privacy and security policies. The partnership ecosystem is not evident from the website. Growth indicators include a long domain history and a specialized product offering.

Security posture

The website demonstrates a low to moderate security maturity level. Key vulnerabilities include lack of HTTPS, absence of security headers, and loading external scripts over unsecured HTTP. No privacy or cookie policies are present, indicating compliance gaps with GDPR and related regulations. Contact forms use POST but lack visible anti-spam or CAPTCHA protections. Incident response and security policy information are missing, reducing readiness perception. No certifications or vulnerability disclosure programs are evident. These gaps expose the business to potential data interception and compliance risks.

Recommendations

  1. Implement HTTPS across the entire website with a valid SSL certificate to secure data in transit.
  2. Add comprehensive privacy and cookie policies to comply with GDPR and enhance user trust.
  3. Use secure (HTTPS) versions of all external libraries and scripts to prevent mixed content issues.
  4. Introduce security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  5. Deploy CAPTCHA or other anti-spam measures on contact forms to reduce abuse and improve security.

Technical notes

Notes

The website is built with basic web technologies including HTML5, CSS, and jQuery. It lacks modern frameworks or CMS platforms, indicating a custom or lightweight implementation. Hosting appears to be managed via Croatian registrar CARNET with DNS servers at studio4web.com. Performance is moderate with no explicit optimization or accessibility features detected. SEO is basic with minimal meta tags and no structured data or Open Graph tags. Mobile optimization is present but limited. The technical debt includes outdated script loading methods and missing security best practices, which could impact user trust and operational security.
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.
