# Security essentials

## Keys and credentials

* Store `PERCEPTRON_API_KEY` in secret managers or environment variables.
* Rotate keys regularly; delete unused credentials immediately.
* Avoid committing keys to version control—use pre-commit hooks to block secrets.

## Data hygiene

* Sanitize prompts and logs to remove PII before persistence.
* Clamp coordinates before storing to prevent overflows: `max(0, min(1000, value))`.
* Encrypt payloads at rest when exporting JSON to object storage.

## Edge deployment

* Use TLS between clients and self-hosted endpoints.
* Lock down firewall rules to trusted IP ranges.
* Rotate `PERCEPTRON_API_KEY`/`FAL_KEY` via your secret manager, then reload the worker processes so they pick up the new token.
* Keep a separate key per device or workload so compromised hardware can be revoked without downtime elsewhere.
