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

Supernova is a technology company providing a SaaS design system platform that integrates design and engineering data to accelerate product development. The platform targets design and engineering teams in medium to large enterprises, offering services such as design system management, code automation, and design tokens. The website is professionally designed, mobile-optimized, and rich in content, reflecting a mature digital presence. Technically, the site uses modern web technologies including Webflow CMS, Google Tag Manager, and Hotjar for analytics and user behavior tracking. Security posture is strong with HTTPS enforced and standard security headers present, though explicit security policies and incident response contacts are not published. Privacy compliance is well addressed with a comprehensive privacy policy and cookie consent mechanism. However, the inability to extract WHOIS data limits domain trust verification, slightly reducing overall business credibility. Overall, the website demonstrates a high level of professionalism and technical maturity with room for improvement in transparency of security and contact information.

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

1 finding rated critical or high. Fix these first.

  1. 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

Supernova positions itself as a trusted partner for companies scaling design systems globally. Its business model is SaaS-based, focusing on design system lifecycle management and automation. The presence of major client logos indicates established market presence and credibility. The platform integrates with existing tooling ecosystems, enhancing communication and efficiency for product teams. Growth indicators include comprehensive resources, learning materials, and active blog and event sections. The company targets enterprise and design operations segments, emphasizing flexibility and connected ecosystems. Strategic partnerships or subsidiaries are not evident from the data. The business exhibits strong branding consistency and content quality, supporting its market positioning as a technology innovator in design system management.

Security posture

The website enforces HTTPS with strong SSL configuration and includes key security headers such as Content-Security-Policy and Strict-Transport-Security, indicating good baseline security practices. Cookie consent and privacy policies demonstrate compliance with GDPR and related regulations. However, the absence of published security policies, incident response procedures, and vulnerability disclosure mechanisms suggests gaps in transparency and readiness communication. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The lack of direct contact information for security or abuse reporting reduces the site's security posture from a compliance and incident management perspective. Overall, the security maturity is good but could be enhanced by publishing formal policies and contact channels.

Recommendations

  1. Publish a dedicated security policy page detailing security practices and compliance frameworks.
  2. Provide clear incident response contact information including security@ or abuse@ email addresses.
  3. Implement and publicize a vulnerability disclosure policy or security.txt file.
  4. Add verified company contact emails and phone numbers to improve business credibility and user trust.
  5. Regularly audit WHOIS data availability and ensure domain registration information is accessible and accurate.

Technical notes

Notes

The website is built on Webflow CMS, leveraging modern JavaScript libraries such as jQuery, Fancybox, and Slick Carousel for UI enhancements. It uses Google Tag Manager and Hotjar for analytics and user behavior tracking, indicating a mature approach to data-driven insights. The site is well optimized for mobile devices and demonstrates fast loading times. SEO is supported by comprehensive meta tags and Open Graph data. Accessibility features are present but could be further enhanced with ARIA roles and landmarks. Hosting is via Webflow's CDN, providing reliable performance and security. Technical risks are minimal, with no outdated or vulnerable libraries detected. Opportunities exist to improve technical documentation and integrate additional security headers or monitoring tools.
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.
