AI security for enterprise engineering teams
Your developers use AI.
Your IP stays private.
Pretense is an AI firewall that mutates proprietary code before it reaches any LLM. Real identifiers never leave your network. Deploys in 30 seconds. Works with every AI tool your team already uses.
The threat is real
Every day, proprietary code leaks to LLM providers through AI coding tools. Traditional DLP can't stop it — it doesn't understand code.

Works with every AI tool your team uses
How it works
Three commands. Full protection.
Install
curl -fsSL pretense.ai/install.sh | shmacOS, Linux, WSL. No dependencies.
Scan & configure
pretense initScans your repo. Creates mutation config.
Protected
pretense startLocal proxy. All AI traffic mutated.
Point your AI tools at localhost:9339 and every identifier is mutated before it leaves your machine. Responses are automatically reversed.
Why Pretense
The only AI firewall that mutates code
Traditional DLP blocks or redacts. Pretense mutates — so the LLM still gets working code, but your identifiers are synthetic.
Code mutation, not redaction
Every identifier — functions, variables, classes — is deterministically mutated to synthetic tokens. The LLM gets working code it can reason about. Your IP stays private.
Secrets blocked at the edge
API keys, tokens, passwords, and PII are detected and blocked before they leave your machine. 30+ patterns covering every major secret format.
Enterprise-grade compliance
SOC2, HIPAA, GDPR, and PCI-DSS ready. Full audit trail of every mutation. Immutable logs for your security team and regulators.
