Definition AI: Security
Definition AI is fully private and secure.
It encrypts everything you enter and upload and no input or output data is used by OpenAI, Google or Anthropic for AI training purposes.

Data privacy and protection
- We don’t process any of your data
- We don’t send any personally identifiable information (PII) to AI vendors
- We can delete all of your account data if you ask us to
- Definition AI complies with GDPR, CCPA, and SOC 2 standards
Data security and encryption
- We encrypt all data using AES-256 encryption and TLS protocols whether it’s moving across the internet or stored on our servers
- Our platform uses AWS Key Management for encryption key generation, storage and lifecycle management
- We logically and physically segment all data within AWS – this means we keep client data separate in our private cloud
Access control and authentication
- Secure login using Google or Microsoft Single Sign-On for all users
- We secure all API endpoints against unauthorised access using OAuth2
- We strictly control access to the cloud environment with rigorous identity and access management policies
Infrastructure security
- Our platform operates within an AWS Virtual Private Cloud (VPC), making sure we have network-level isolation
- We use AWS Sentry and CloudWatch to monitor for security incidents
Application and API security
- We conduct Static Application Security Testing (SAST) and Dynamic Application Security Testing (DAST) in staging environments to detect runtime vulnerabilities related to authentication, session management, and API security
- We run code reviews for all development work, with a focus on OWASP Top Ten
- We run an OWASP dependency check to scan all third-party libraries for known vulnerabilities
Incident response and threat management
- Two-hour threat SLA – initial identification and escalation take place within two business hours, with a solution implemented within one business day
