Bubble Group, Inc operates bubble.io, a leading no-code platform that empowers users to build web and mobile applications using AI-powered visual editing tools. Founded in 2008 and based in the US, Bubble has established itself as a mature and reputable player in the no-code SaaS market, targeting developers, startups, and businesses seeking rapid app development without coding expertise. The platform supports native mobile app publishing and integration with AI models like OpenAI and Anthropic, positioning itself as a comprehensive solution for modern app creation. Technically, the website leverages a modern tech stack including JavaScript frameworks, Google Fonts, Stripe for payments, Segment Analytics, Hotjar, and other libraries to deliver a performant and user-friendly experience. Hosting and DNS are managed via Cloudflare and AWS Cloudfront, ensuring reliable delivery and security. The site is mobile-optimized and uses structured data for SEO enhancement. However, accessibility features are basic and could be improved. From a security perspective, the site enforces HTTPS and uses Cloudflare DNS with clientTransferProhibited domain status, indicating good domain security practices. Cookie consent is implemented, but explicit privacy policies, terms of service, security policies, and incident response information are not found in the provided content, representing areas for compliance improvement. No vulnerabilities or suspicious patterns were detected. Overall, bubble.io presents a professional, trustworthy, and technically sound platform with strong business credibility. Strategic recommendations include publishing comprehensive privacy and security policies, enabling DNSSEC, enhancing accessibility, and providing vulnerability disclosure mechanisms to further strengthen compliance and user trust.

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

5 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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

  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
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

Bubble is positioned as a market leader in the no-code app development space, leveraging AI to differentiate its offering. Its business model is SaaS-based, monetizing through platform subscriptions and services for building marketplaces, SaaS platforms, and internal tools. The company targets a broad audience including non-technical users and developers, enabling rapid app creation. The presence of testimonials, social media presence, and structured data indicates a mature marketing and partnership ecosystem. The domain age and registrant information align with the company's claimed history, supporting credibility. Growth indicators include integration with AI services and native mobile app publishing capabilities.

Security posture

The website demonstrates a good security posture with HTTPS enforced, Cloudflare DNS and registrar usage, and domain status clientTransferProhibited. However, the absence of DNSSEC and explicit security headers like CSP and X-Frame-Options are gaps. No security or incident response policies are published, which limits transparency and preparedness perception. Cookie consent is implemented, supporting privacy compliance. No exposed sensitive data or vulnerable libraries were detected. Overall, security maturity is moderate to good but can be enhanced by publishing policies and enabling additional DNS and HTTP security features.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service accessible from the main website.
  2. Implement and publish a security policy and incident response plan with clear contact channels.
  3. Enable DNSSEC to improve DNS security and prevent spoofing.
  4. Add and enforce security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  5. Enhance website accessibility features to meet WCAG standards and improve user inclusivity.

Technical notes

Notes

The website uses a modern and diverse technology stack including JavaScript libraries for animations, UI components, analytics, and AI integration. Hosting is via Cloudflare and AWS Cloudfront, providing scalability and performance. The site is mobile-optimized and uses structured data for SEO. Some technical debt is indicated by missing security headers and basic accessibility. Performance is moderate, with room for optimization. The proprietary Bubble platform serves as the CMS and app builder, indicating a high level of technical maturity but also reliance on a single vendor ecosystem.
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.
