NIS2 Art. 21(2)

  1. (a) Risk analysis and security policies: Not visible from outside

  3. (c) Business continuity, backups and crisis management: Not visible from outside
  4. (d) Supply chain security: Not visible from outside

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

6 findings rated critical or high. Fix these first.

  1. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • Critical

      DNS Resolution Failed

      Unable to resolve domain A records

      What to do: Verify domain is properly configured and not expired

    • High

      Unregistered MX Record

      MX record points to unregistered domain: alt2.aspmx.l.google.com

      What to do: Remove or fix MX record pointing to unregistered domain

      • RFC 5321 §5.1
      • NIS2 21(2)(i)
      • IR 2024/2690 12.4: Implementing Regulation (EU) 2024/2690, Annex point 12.4: Asset inventory
      • NIST CM-8: NIST SP 800-53 Rev. 5 CM-8: System Component Inventory

  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 targets medium to large enterprises seeking to unify and control customer data flows across multiple platforms. Their business model is subscription-based SaaS with a focus on data infrastructure and compliance. The company leverages a strong partnership ecosystem and showcases customer success through detailed case studies and testimonials. Their market position is solidified by certifications and a comprehensive product suite addressing data integration, transformation, and governance. Growth indicators include active marketing, live tech sessions, and a hiring presence. The company maintains a consistent brand and professional content that supports trust and credibility.

Security posture

The website demonstrates a high level of security maturity with enforced HTTPS, presence of key security headers, and no visible vulnerabilities or exposed sensitive data. Compliance with GDPR, HIPAA, and SOC 2 standards is clearly communicated, supported by dedicated security and vulnerability disclosure pages. Incident response readiness is indicated by published contact channels for security issues. However, the lack of a cookie consent mechanism and security.txt file are minor gaps. Overall, the security culture appears robust and aligned with industry best practices, minimizing business risk related to data breaches or compliance violations.

Recommendations

  1. Implement a visible cookie consent banner to comply with privacy regulations and enhance user trust.
  2. Publish a security.txt file to facilitate security researchers in reporting vulnerabilities.
  3. Add explicit Data Protection Officer contact information to improve GDPR compliance transparency.
  4. Regularly audit third-party scripts and tracking tools to ensure minimal privacy impact.
  5. Enhance contact information visibility, including verified company emails and phone numbers, to improve business credibility.

Technical notes

Notes

The website is built on a modern React and Next.js framework, leveraging server-side rendering and static asset optimization for performance. Hosting appears to be on Vercel, contributing to fast load times and excellent mobile responsiveness. SEO is well addressed with comprehensive meta tags and Open Graph data. Accessibility features are present but could be further enhanced with ARIA landmarks and keyboard navigation improvements. No CMS is detected, indicating a custom or headless architecture. The technical stack supports scalability and maintainability, though ongoing monitoring of third-party dependencies is recommended to avoid security risks.
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.
