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

Snowplow Analytics Ltd operates a sophisticated composable customer data infrastructure platform designed to empower data and product teams with real-time, AI-ready behavioral data. Positioned as a global leader in behavioral data for AI, Snowplow offers a suite of services including event tracking, data pipelines, and real-time personalization tools, targeting digital-first companies and AI application developers. The company maintains a strong market presence with a medium-sized operation founded in 2012 and headquartered in the UK with a US office in Boston. Technically, the website leverages modern web technologies including Webflow CMS, Cloudflare DNS, and a variety of JavaScript trackers and analytics tools such as Snowplow Tracker, Google Tag Manager, and Smartlook. The site is well optimized for performance, mobile responsiveness, and accessibility, reflecting a mature digital infrastructure. From a security perspective, Snowplow demonstrates a robust posture with enforced HTTPS, multiple security headers, and a comprehensive cookie consent mechanism. However, DNSSEC is not enabled, and there is no public vulnerability disclosure or incident response contact information, which are areas for improvement. Overall, the website and business exhibit high professionalism, trustworthiness, and compliance with privacy regulations including GDPR. The domain registration data aligns well with the company's claims, supporting legitimacy. Strategic recommendations include enabling DNSSEC, publishing vulnerability disclosure policies, and enhancing incident response transparency to further strengthen security and 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

3 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
  2. 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.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1
    • High

      SSL Certificate Expires Soon

      SSL certificate expires in 27 days

      What to do: Renew SSL certificate before expiration

      • NIS2 21(2)(h)
      • IR 2024/2690 9.2(c): Implementing Regulation (EU) 2024/2690, Annex point 9.2(c): Cryptography
      • NIST SC-17: NIST SP 800-53 Rev. 5 SC-17: Public Key Infrastructure Certificates

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.

Business context

Business profile

Snowplow Analytics Ltd is strategically positioned in the technology sector as a provider of composable customer data infrastructure, focusing on AI-driven behavioral data solutions. Their business model revolves around B2B SaaS and open-source infrastructure, serving data engineering, product, and AI teams. The company benefits from a strong partnership ecosystem including AWS, Databricks, Snowflake, and Google Cloud, enhancing its integration capabilities. Growth indicators include a comprehensive product portfolio, active community engagement via GitHub and forums, and a clear focus on real-time data and AI applications. The company’s market positioning as a global leader in behavioral data infrastructure is supported by consistent branding, professional content, and trust signals such as detailed security and compliance documentation.

Security posture

Snowplow's security maturity is solid, with HTTPS enforced site-wide, use of security headers, and clientTransferProhibited domain status to prevent unauthorized transfers. The presence of a cookie consent banner with granular controls indicates privacy-conscious data handling. No exposed sensitive data or vulnerable libraries were detected in the website content. However, the absence of DNSSEC and a public vulnerability disclosure or security.txt file suggests room for improvement in DNS security and transparency. Incident response readiness is not explicitly documented, which could impact rapid mitigation of security incidents. Overall, the security culture appears proactive but could benefit from formalized disclosure and response policies.

Recommendations

  1. Enable DNSSEC to enhance DNS security and prevent spoofing.
  2. Publish a vulnerability disclosure policy or security.txt file to improve transparency and encourage responsible reporting.
  3. Provide explicit incident response contact information to facilitate timely communication during security events.
  4. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.
  5. Enhance security certifications and frameworks documentation to strengthen trust with enterprise clients.

Technical notes

Notes

The website is built on a modern technology stack including Webflow CMS, JavaScript trackers, and integrations with multiple analytics and marketing platforms. Hosting and DNS are managed via Cloudflare, providing performance and security benefits. The site demonstrates fast loading times, excellent mobile optimization, and good accessibility features. Technical debt appears minimal, with up-to-date libraries and well-structured content. Opportunities for modernization include enabling DNSSEC and consolidating third-party scripts to reduce complexity and potential attack surface. Technical risks are low but should be monitored through continuous security assessments.
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.
