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

Stockdio is a specialized technology company offering financial market analytics and charting services primarily targeted at developers, financial consultants, bloggers, and project managers. The platform emphasizes ease of integration, scalability, and customization, providing REST APIs and embeddable charts with included market data from multiple international exchanges. The website reflects a professional and consistent brand image, supported by a small but focused business entity founded in 2015 and associated with parent company Software FX. Technically, the site uses modern web technologies including jQuery, Foundation CSS, Google Fonts, and Google Tag Manager, hosted on AWS infrastructure. Performance and mobile optimization are adequate, with good SEO practices in place. Security posture is moderate with HTTPS enforced and domain transfer protection, but lacks advanced security headers and DNSSEC. Privacy compliance is basic, with a privacy policy present but no cookie consent mechanism despite use of tracking and advertising scripts. Contact information is limited to an email address and contact form, with no phone or physical address provided. Overall, the site is trustworthy and functional but could improve in privacy and security transparency.

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

6 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 Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

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

Stockdio occupies a niche in the financial technology sector, providing SaaS-based financial data visualization tools and APIs. Its competitive advantage lies in ease of use, no-code integration, and included market data without additional subscriptions. The business model is subscription-based with scalable pricing, targeting developers and financial professionals who need fast deployment of financial charts and dashboards. The company leverages partnerships with its parent Software FX and uses CDN delivery for performance. Growth indicators include a diverse target audience and multiple use cases showcased on the site. The ecosystem includes integrations with WordPress and iFrames, and marketing is supported by Google Ads and social sharing tools. Strategic observations suggest opportunities to enhance privacy compliance and security posture to strengthen market trust.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enabled and domain transfer protection in place. However, it lacks implementation of key security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options, which are important for mitigating common web vulnerabilities. DNSSEC is not enabled, which could improve domain security. No incident response or security policy documents are published, and no dedicated security contact channels are provided. The presence of third-party advertising and tracking scripts increases the importance of robust privacy and security controls. Overall, while no critical vulnerabilities are evident, the site would benefit from enhanced security best practices and transparency to align with GDPR and industry standards.

Recommendations

  1. Enable DNSSEC to improve domain name system security.
  2. Implement and configure security headers including CSP, X-Frame-Options, and X-Content-Type-Options.
  3. Add a cookie consent banner and mechanism to comply with GDPR and enhance user privacy.
  4. Publish a clear security policy and incident response contact information on the website.
  5. Regularly audit third-party scripts and minimize tracking to reduce privacy risks.

Technical notes

Notes

The website is built using standard modern web technologies such as HTML5, CSS3, JavaScript, and jQuery, with Foundation CSS framework for responsive design. It uses Google Fonts for typography and Google Tag Manager for analytics. Hosting is on AWS infrastructure, indicated by DNS servers. Performance is moderate with some use of CDN for content delivery. The site is mobile optimized and SEO friendly with proper meta tags and Open Graph data. There is no detected CMS, suggesting a custom or static site build. Technical risks include lack of advanced security headers and no DNSSEC, which could be addressed to improve resilience. The site’s architecture supports scalability and ease of integration, aligning well with its business goals.
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.
