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

RudderStack Inc. operates a sophisticated SaaS platform focused on customer data infrastructure, enabling businesses to collect, transform, and deliver real-time customer event data with strong privacy controls. Positioned as a reliable and scalable solution, RudderStack offers a broad suite of services including a Customer Data Platform, event streaming, profiles, reverse ETL, and compliance toolkits. The company targets enterprises and technology-driven businesses seeking to enhance data-driven personalization and analytics. Technically, the website leverages modern frameworks such as Next.js and React, hosted on Vercel, ensuring fast performance and excellent mobile optimization. The integration of analytics tools like PostHog, Microsoft Clarity, and Hockeystack reflects a mature digital infrastructure focused on user behavior insights. The site demonstrates good SEO and accessibility practices, though there is room for improvement in security headers and cookie consent mechanisms. From a security perspective, RudderStack emphasizes compliance with major standards including SOC 2, HIPAA, and GDPR, supported by visible certifications and a vulnerability disclosure policy. However, the absence of WHOIS data and lack of explicit security headers slightly diminish the overall security posture. No critical vulnerabilities or exposed sensitive data were detected. Overall, RudderStack presents a professional, trustworthy, and privacy-conscious business platform with strong technical foundations. The main risk lies in the missing WHOIS transparency and minor security header gaps, which should be addressed to enhance trust and compliance further.

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 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

  3. 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

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

RudderStack holds a competitive position in the customer data platform market, differentiating itself through real-time data processing and strong privacy controls. Its business model is SaaS-based, targeting medium to large enterprises that require scalable and compliant data infrastructure. The company leverages partnerships and a rich integration ecosystem to expand its market reach. Customer testimonials and case studies indicate successful deployments and measurable business impact, such as increased revenue and productivity gains. The absence of direct contact emails or phone numbers suggests a focus on digital engagement and lead generation via forms. The company maintains a consistent brand and content strategy, reinforcing its technology sector identity.

Security posture

The security posture of RudderStack is solid, with adherence to recognized compliance frameworks like SOC 2, HIPAA, and GDPR. The website uses HTTPS exclusively, ensuring encrypted communications. The presence of a vulnerability disclosure policy indicates proactive security management. However, the lack of visible security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options represents an area for improvement. No incident response contact channels or security.txt file were found, which could enhance incident handling readiness. Overall, the company demonstrates a mature security culture but should enhance technical controls and transparency to mitigate risks further.

Recommendations

  1. Implement and enforce security headers including CSP, HSTS, and X-Frame-Options to strengthen web security.
  2. Add a cookie consent banner or mechanism to comply fully with privacy regulations and improve user transparency.
  3. Publish a security.txt file and provide clear incident response contact information to facilitate vulnerability reporting and response.
  4. Disclose Data Protection Officer contact details to enhance GDPR compliance and user trust.
  5. Regularly audit and update third-party scripts and analytics tools to minimize potential vulnerabilities.

Technical notes

Notes

The website is built on a modern technology stack featuring Next.js and React, hosted on Vercel, which supports fast loading times and excellent mobile responsiveness. The use of Font Awesome icons and integration of analytics services like PostHog and Microsoft Clarity indicate a focus on user experience and data-driven insights. The site structure is well-organized with comprehensive metadata and Open Graph tags for SEO and social sharing. However, the absence of explicit security headers and cookie consent mechanisms suggests some technical debt in security best practices. The WHOIS data is missing, which may indicate privacy protection or registrar issues, warranting further investigation. Overall, the technical implementation is robust but can be improved in security and privacy compliance areas.
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.
