59/100

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

Flow Traders is a well-established global trading firm specializing in providing continuous liquidity and driving transparency in financial markets. The company operates across multiple continents with a strong focus on institutional trading, digital assets, and strategic capital investments. Their website reflects a professional and modern digital presence, leveraging advanced JavaScript frameworks and analytics tools to enhance user experience and data insights. However, a critical security gap exists due to the absence of a valid SSL certificate, which undermines the site's HTTPS security and could impact user trust and data protection. Despite this, privacy and cookie policies are clearly presented, indicating a commitment to regulatory compliance. Overall, Flow Traders demonstrates a strong market position and digital maturity but should urgently address SSL/TLS issues to improve security posture and user confidence.

Both readouts depend on the site's pages, which could not be loaded in this scan.

Priority findings

1 finding rated critical or high. Fix these first.

  1. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

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

  • Security headers: did not complete in this scan.
  • GDPR outside view: did not complete in this scan.
  • 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

Flow Traders targets institutional investors and financial market participants, offering liquidity provision and strategic investments. Their business model is centered on leveraging technology and market expertise to reduce trading costs and foster innovation. The company maintains a large workforce with significant investment in technology, indicating a robust operational infrastructure. Their global footprint and investor relations content suggest a mature and transparent organization. The absence of direct contact details on the homepage may indicate a preference for controlled communication channels. Social media engagement across major platforms supports brand visibility and stakeholder engagement.

Security posture

The website is protected by Cloudflare, providing CDN and basic security features, including a Strict-Transport-Security header. However, the lack of a valid SSL certificate and disabled TLS protocols represent significant vulnerabilities, exposing users to potential interception and trust issues. No vulnerable libraries or known exploits were detected in the scripts used. The site lacks advanced security headers and mechanisms such as OCSP stapling and session resumption, which could enhance security and performance. No explicit security or incident response policies are published, limiting transparency on how security incidents are managed. Immediate remediation of SSL/TLS issues is critical to elevate the security posture.

Recommendations

  1. Obtain and deploy a valid SSL/TLS certificate to enable secure HTTPS connections.
  2. Enable and enforce modern TLS protocols (TLS 1.2 and TLS 1.3) with strong cipher suites.
  3. Enhance HSTS policy by including subdomains and submitting for preload list.
  4. Implement OCSP stapling and session resumption to improve security and performance.
  5. Publish clear security and incident response policies to increase transparency and trust.
Technical notes

Notes

The website uses a modern technology stack including Vue.js for frontend interactivity, Swiper.js for carousels, and Microsoft Application Insights for telemetry. It is hosted behind Cloudflare, which provides CDN and security services. The site appears to be built on Umbraco CMS, inferred from HTML classes. Performance metrics are not available, but the site includes responsive design elements and mobile-optimized navigation. SEO practices are evident with proper meta tags and structured navigation. However, the lack of valid SSL impacts overall technical quality and user trust. The site uses multiple external resources from reputable domains, ensuring reliability and scalability.
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.
