Bubble.io Security: Is It Safe Enough for Real Business Data?
SOC 2 Type II certified. Fortune 500 companies use Bubble-built products. But platform security and application security are different things. An honest breakdown of what Bubble provides at the platform level and what the developer must implement correctly.
Can Bubble.io Be Trusted With Real Customer Data?
This is the question every enterprise prospect asks and every founder worries about. The answer is nuanced: Bubble.io the platform has enterprise-grade security infrastructure. Bubble.io applications, however, are only as secure as the architecture choices made by the developer who built them. A well-architected Bubble app is genuinely secure. A poorly-architected one is not. This guide covers both.
What Bubble.io Provides at the Platform Level
SOC 2 Type II Certified
Bubble achieved SOC 2 Type II certification in 2023. This independent audit covers security, availability, and confidentiality controls. Fortune 500 companies including Microsoft, Deloitte, and VMware actively use Bubble-built products in production.
Data Encryption
All data is encrypted in transit (HTTPS/TLS) and at rest via AWS infrastructure. Bubble uses AWS with AES-256 encryption at rest. These are the same standards used by major financial institutions and healthcare providers.
GDPR Compliance
Bubble provides a Data Processing Agreement (DPA) for customers who need to comply with GDPR. Data is hosted in the United States by default, with Enterprise options for EU data residency. Bubble also provides tools for data export and deletion.
Authentication
Bubble’s built-in authentication uses industry-standard secure password hashing (bcrypt). OAuth integration (Google, Facebook, Apple) is available via official plugins. Two-factor authentication can be implemented via third-party TOTP plugins.
Infrastructure
Bubble runs on AWS infrastructure with automatic backups, geographic redundancy, and enterprise SLAs on Enterprise plans. The platform has maintained 99.9%+ uptime since 2022 for Growth and above plans.
Penetration Testing
Bubble conducts regular third-party security assessments. Enterprise customers can request the latest penetration test report and security questionnaire responses from Bubble’s enterprise sales team.
What the Developer Must Get Right (And What Can Go Wrong)
Platform security is Bubble’s responsibility. Application security is yours. The most common security vulnerabilities in Bubble applications are not platform vulnerabilities — they are architectural errors made by developers who did not implement the available security features correctly.
| Security Feature | What It Does | What Happens Without It |
|---|---|---|
| Privacy Rules | Controls which users can read/write each data type. Enforced server-side. | Users can access other users’ data via the API or direct searches |
| Workspace Isolation | Scopes all data to the correct tenant. | Multi-tenant apps leak data between customers |
| Role Checks in Workflows | Verifies user has permission before any sensitive action. | Users can perform admin actions by calling API directly |
| Webhook Validation | Validates Stripe webhook signatures before processing. | Spoofed webhooks can manipulate billing state |
| Secure API Credentials | Stores API keys as private, not in visible data fields. | API keys exposed to browser-side JavaScript |
Security Questions We Are Asked Most Often
Q: Has Bubble.io ever had a data breach?
We are not aware of any significant platform-level data breach at Bubble.io. Individual applications built on Bubble may have had security issues due to misconfigured privacy rules, but these are application-level issues, not platform-level breaches.
Q: Can enterprise customers trust Bubble.io?
Yes. Multiple Fortune 500 companies including Microsoft, Deloitte, and VMware actively use Bubble-built products. Bubble’s SOC 2 Type II certification satisfies most enterprise security questionnaire requirements.
Q: What should I look for when assessing a Bubble app’s security?
Ask the developer to demonstrate: tenant isolation (can User A see User B’s data?), privacy rule configuration on every data type, role checks in sensitive workflows, and webhook signature validation in the Stripe integration.
Q: Is Bubble safe for healthcare data?
Bubble with a signed BAA (Business Associate Agreement) on Enterprise plan can be used for HIPAA-adjacent administrative data. For clinical records, a purpose-built HIPAA-certified system is required regardless of what application is built on top.
