Secure by Design

Security-First Architecture for Code Reviews

ThinkReview is built with security as a foundational principle, not an afterthought. Every aspect of our code review platform—from data transmission to code analysis—is designed with enterprise-grade security measures to protect your source code and sensitive data.

How We Secure Your Code Review Data

1. Encrypted Data Transmission

All code review data is protected in transit:

• HTTPS/TLS Encryption: All communications between your browser, our extension, and our servers use TLS 1.2+ encryption.
• Secure API Endpoints: Code review requests are sent to secure, authenticated endpoints using industry-standard protocols.
• Certificate Pinning: We use verified SSL certificates to prevent man-in-the-middle attacks.
• No Unencrypted Transmission: We never transmit code diffs or review data over unencrypted connections.

2. Secure Authentication

Your account and code reviews are protected by robust authentication:

• Google OAuth 2.0: Industry-standard OAuth protocol eliminates password storage and reduces attack surface.
• No Password Storage: We never store passwords—authentication is handled entirely by Google's secure infrastructure.
• Session Management: Secure session tokens with automatic expiration protect against session hijacking.
• Multi-Factor Authentication: Leverages Google's MFA capabilities when enabled on your Google account.

3. Code Review Data Protection

Your source code is handled with the highest security standards:

• No Persistent Storage: Code diffs are processed in real-time and immediately discarded—never stored in databases.
• In-Memory Processing: Code reviews are processed in secure, isolated environments with no disk persistence.
• Zero Code Retention: Your source code never remains on our servers after review completion.
• Access Logging: All code review requests are logged for security auditing, but logs contain no code content.

4. Infrastructure Security

Our backend infrastructure follows security best practices:

• Google Cloud Platform: Enterprise-grade cloud infrastructure with built-in security controls.
• Firebase Security Rules: Strict Firestore security rules prevent unauthorized data access.
• Network Isolation: Services run in isolated network environments with restricted access.
• Regular Security Updates: All systems are kept up-to-date with the latest security patches.
• DDoS Protection: Infrastructure includes protection against distributed denial-of-service attacks.

5. Secure Code Analysis

AI code review processing maintains security throughout:

• Isolated Processing: Code reviews are processed in isolated containers with no access to other user data.
• Secure AI Integration: Code diffs are sent to Google's Gemini API over encrypted connections with authentication.
• No Code Training: Your code is never used to train AI models—it's analyzed and immediately discarded.
• Input Validation: All code review requests are validated and sanitized before processing.
• Rate Limiting: API rate limits prevent abuse and ensure service availability.

6. Extension Security

Our Chrome extension follows security best practices:

• Minimal Permissions: Extension only requests necessary permissions for GitLab/Azure DevOps domains.
• Content Security Policy: Strict CSP prevents injection attacks and unauthorized script execution.
• Sandboxed Execution: Extension code runs in Chrome's secure sandbox environment.
• Regular Updates: Extension is regularly updated with security patches and improvements.
• Code Signing: Extension is published through Chrome Web Store with verified developer identity.

7. Access Controls

Strict access controls protect your data:

• Principle of Least Privilege: Only authorized personnel have access to systems, and only with minimum required permissions.
• Audit Logging: All system access is logged and monitored for suspicious activity.
• User Isolation: Each user's data is isolated—no cross-user data access is possible.
• API Authentication: All API requests require valid authentication tokens.

8. Incident Response

We maintain readiness for security incidents:

• Security Monitoring: Continuous monitoring for security threats and anomalies.
• Incident Response Plan: Documented procedures for responding to security incidents.
• Vulnerability Disclosure: Responsible disclosure process for security researchers.
• Regular Security Audits: Periodic security assessments and penetration testing.

9. Code Review Privacy Controls

You maintain full control over your code reviews:

• User-Initiated Only: Code reviews only occur when you explicitly request them—no automatic scanning.
• Selective Review: You choose which merge requests or pull requests to review.
• No Repository Access: Extension never gains full repository access—only processes diffs you view.
• Local Processing Options: Code diffs are processed locally in your browser before transmission when possible.

10. Compliance and Certifications

Our security practices align with industry standards:

• GDPR Compliance: Meets European data protection requirements.
• CCPA Compliance: Meets California privacy regulations.
• Industry Best Practices: Follows OWASP security guidelines and cloud security frameworks.
• Third-Party Security: All service providers (Google Cloud, Firebase) maintain their own security certifications.
