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

RudderStack Inc. operates a sophisticated SaaS platform focused on real-time customer data infrastructure, enabling businesses to collect, transform, and deliver customer event data with strong privacy controls. Positioned as a competitive player in the customer data platform market, RudderStack offers a suite of services including event streaming, profiles, reverse ETL, and compliance toolkits. The website reflects a mature digital presence with excellent design, clear navigation, and comprehensive content targeting business and enterprise customers. Technically, the site leverages modern web technologies such as React and Next.js, hosted likely on Vercel, ensuring fast performance and mobile optimization. Security posture is strong with HTTPS enforcement, multiple security headers, and visible compliance certifications like SOC 2 and HIPAA. However, the absence of a cookie consent mechanism and direct contact emails slightly detract from privacy compliance completeness. The WHOIS data is notably missing, which raises questions about domain registration transparency. Despite this, the website's professional content, certifications, and customer testimonials support its legitimacy. Overall, RudderStack demonstrates a robust security and compliance stance with room for improvement in transparency and user privacy controls. Strategically, the company should prioritize publishing clear domain registration information, enhancing cookie consent transparency, and providing direct contact channels for security and privacy inquiries to strengthen trust and compliance.

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. 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

  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

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 targets mid to large enterprises requiring advanced customer data infrastructure solutions. Its SaaS business model focuses on delivering integrations, data transformation, and compliance tooling, positioning it well against competitors in the CDP and event streaming space. The presence of multiple case studies and testimonials indicates a growing customer base and effective value delivery. The company maintains a strong partnership and marketing ecosystem, leveraging podcasts and technical sessions to engage its audience. Growth indicators include feature launches and integration expansions. The lack of visible direct contact info suggests a focus on digital lead generation via forms and demos.

Security posture

The website exhibits a mature security posture with HTTPS, robust security headers, and compliance certifications (SOC 2, HIPAA, GDPR). No vulnerabilities or exposed sensitive data were detected in the HTML content. However, the absence of a published security.txt file and incident response contact emails limits incident handling transparency. Privacy compliance is good but could be improved with explicit cookie consent mechanisms. The site’s security culture is evidenced by integrated data governance messaging and compliance toolkits, indicating organizational commitment to security and privacy.

Recommendations

  1. Implement a visible cookie consent banner to enhance GDPR compliance and user transparency.
  2. Publish a security.txt file and provide explicit incident response contact channels (e.g., security@ or abuse@ emails).
  3. Disclose domain registration details or ensure WHOIS privacy protection is justified and transparent.
  4. Add direct company contact emails and phone numbers for sales, support, and security inquiries to improve trust.
  5. Regularly audit third-party scripts and tracking services to minimize potential vulnerabilities.

Technical notes

Notes

The website is built on a modern tech stack including React and Next.js, optimized for performance and mobile responsiveness. Hosting appears to be on a scalable platform like Vercel, supporting fast load times and global delivery. The site uses SVG logos and optimized images for crisp visuals. SEO is well addressed with meta tags and Open Graph data. Accessibility is good with semantic HTML and ARIA attributes. No CMS detected, indicating a custom or proprietary content management approach. The technical implementation supports a professional and scalable digital presence with minimal technical debt.
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.
