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

Kumu Inc. operates a SaaS platform focused on enabling users to create relationship and systems maps to organize complex data visually. The company targets social sector leaders, organizations, and communities that require advanced mapping tools to understand networks and systems. Their market position is supported by a strong client base including foundations, universities, and NGOs, with a business model centered on free registration and paid plans. Technically, the website is built on Ruby on Rails, hosted on AWS, and uses modern JavaScript libraries, Typekit fonts, and third-party services like Bugsnag and Fathom Analytics. The site is performant, mobile-optimized, and SEO-friendly. Security posture is solid with HTTPS, CSRF protection, and domain transfer restrictions, though improvements like DNSSEC and security headers are recommended. Privacy compliance is basic with a privacy policy present but lacking cookie consent mechanisms. Overall, the domain registration data aligns well with the business, indicating high legitimacy and trustworthiness.

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

Kumu holds a niche leadership position in the relationship and systems mapping market, serving a specialized audience focused on social impact and complex data visualization. Their competitive advantage lies in an easy-to-use platform with powerful features and a strong customer service ethic. Revenue likely derives from subscription plans, with free onboarding to attract users. The company maintains a professional brand with consistent messaging and notable client endorsements. Partnerships such as Sticky Studio expand their ecosystem. Growth indicators include active hiring and a well-maintained web presence. Strategic observations suggest focusing on enhancing security and privacy compliance to strengthen market trust.

Security posture

The website demonstrates a mature security posture with HTTPS enforced, CSRF tokens implemented in forms, and domain transfer protections. However, the absence of DNSSEC, security headers like Content-Security-Policy, and a vulnerability disclosure policy indicate areas for improvement. No critical vulnerabilities or exposed sensitive data were detected. Incident response contacts are not publicly listed, which could hinder rapid response to security events. Privacy compliance is partial, lacking cookie consent mechanisms and explicit GDPR indicators. Overall, the security maturity is good but could be enhanced with additional controls and transparency.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Implement security headers such as Content-Security-Policy, X-Content-Type-Options, and Strict-Transport-Security.
  3. Add a cookie consent banner or mechanism to comply with privacy regulations and improve user trust.
  4. Publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  5. Provide clear incident response contact information to enhance security communication and readiness.

Technical notes

Notes

The website is built on a modern Ruby on Rails framework, leveraging AWS for hosting and DNS services. It uses asynchronous JavaScript loading, Typekit fonts, and integrates third-party services like Bugsnag for error monitoring and Fathom Analytics for privacy-focused tracking. The site is well-structured with responsive design and good SEO practices. Performance is fast with optimized asset delivery. Technical debt appears low, but the absence of some security headers and DNSSEC suggests opportunities for modernization. Overall, the technical infrastructure supports reliable and scalable operations with room for incremental security enhancements.
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.
