Security

At Kaarta, security is foundational to everything we build. We handle sensitive financial data for businesses, and we take that responsibility seriously. Our platform is designed with security-first principles at every layer.

Every piece of data in Kaarta is associated with a specific business. Our architecture enforces strict tenant isolation:

• All database tables include business identifiers
• API layer validates user access permissions before processing any request
• Users can only access businesses they have explicit membership in

Secure Authentication

• Passwords are hashed using bcrypt with appropriate cost factors
• Short-lived access tokens (15 minutes) minimize exposure window
• Long-lived refresh tokens (30 days) enable seamless re-authentication
• Refresh tokens are stored as secure hashes and can be revoked instantly

Role-Based Access

Business owners control who has access to their data. Each user is assigned a role that determines their permissions within the organization:

• Owner: Full access - can manage users, settings, and all data
• Accountant: View and export access
• Viewer: Read-only access

Encryption in Transit

All data transmitted to and from Kaarta is encrypted using TLS 1.2+. We enforce HTTPS for all connections.

Encryption at Rest

All database storage is encrypted at rest using AES-256 encryption provided by AWS RDS. Backups are similarly encrypted.

• Hosted on AWS enterprise-grade cloud infrastructure (Mumbai region)
• Database and cache services run in private subnets, not directly accessible from the internet
• Regular security patches and updates
• Automated backups with point-in-time recovery
• Structured logging and monitoring for security events
