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

Millistream AB is a Sweden-based financial market data provider established in 2008, specializing in delivering real-time and historical market data, news, and corporate information from major global exchanges such as Nasdaq, NYSE, Deutsche Börse, and London Stock Exchange. The company targets financial institutions including banks, brokers, asset managers, and media companies, primarily in the Nordic region but with growing international reach. Their offerings include APIs, widgets, and a web-based trading application called Millistream Trader, designed to provide efficient and intuitive market views. Technically, the website is built on WordPress with the Enfold theme and leverages modern web technologies including jQuery, Google Analytics, and custom streaming APIs. The infrastructure supports low-latency data delivery via dedicated leased lines and cloud presence on AWS, indicating a mature and scalable technical setup. The site is mobile optimized and SEO friendly, though performance is moderate. From a security perspective, the site uses HTTPS and implements GDPR-compliant cookie consent mechanisms. However, it lacks publicly available privacy policies, terms of service, security policies, and incident response contacts, which are important for compliance and trust. No critical vulnerabilities or exposed sensitive data were detected, but security headers are not explicitly present, and no vulnerability disclosure policy is found. Overall, Millistream presents a professional and credible online presence with solid business and technical foundations. To enhance trust and compliance, it is recommended to publish comprehensive privacy and security policies, provide clear contact channels for security incidents, and implement additional security headers and disclosure mechanisms.

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

4 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 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

      Third-party services without privacy policy

      Detected services: Google Analytics, Google APIs

      What to do: Document all third-party data sharing in your privacy policy

  3. 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.

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

Millistream holds a strong position as a specialized financial data provider in the Nordic market, leveraging long-standing domain registration and a focused product suite tailored to professional financial clients. Their business model centers on B2B data delivery via APIs and widgets, supporting both low-latency and cloud-based clients. The company’s growth is supported by strategic infrastructure investments including co-location and AWS presence. The absence of explicit privacy and security policies may limit trust among some clients, but the detailed product offerings and recent news updates indicate active development and customer engagement. The company’s ecosystem includes partnerships with major exchanges and cloud providers, though no direct partner domains were identified on the website.

Security posture

The website demonstrates a moderate security posture with HTTPS enforced and GDPR cookie compliance implemented. However, the lack of published privacy and security policies, absence of security headers, and no visible incident response or vulnerability disclosure information represent compliance and operational gaps. No critical vulnerabilities or exposed sensitive data were found, and no outdated or vulnerable libraries were detected in the scripts. The security maturity appears adequate for the business scale but could be improved by formalizing policies and enhancing transparency around security practices.

Recommendations

  1. Publish a comprehensive privacy policy page detailing data collection, usage, and user rights.
  2. Add terms of service and security policy documents accessible from the website footer or main menu.
  3. Implement HTTP security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options.
  4. Provide clear incident response contact information, including security@ or abuse@ email addresses.
  5. Consider publishing a vulnerability disclosure policy or security.txt file to encourage responsible reporting.

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.
