CuraIQ reviews prompts on the device — so content never leaves the machine, and it wraps the AI coding agents you already run: Claude Code, Codex, GitHub Copilot CLI. Every prompt is checked locally against policy before it reaches the agent, and security teams see only redacted, content-free signals.
Lakera Guard is a cloud/API AI-security service — prompts are sent to the service for analysis. This is an honest, architecture-level comparison: on-device review versus cloud analysis.
Lakera Guard and CuraIQ solve guardrails at opposite ends of the stack. Lakera Guard is a cloud/API LLM-app firewall: your deployed application calls it to screen the prompts and responses passing through, wherever that app runs. CuraIQ sits one layer earlier — on the developer's own machine — reviewing each prompt to a coding agent locally, before it is ever sent anywhere.
| CuraIQ | Lakera Guard | |
|---|---|---|
| Where prompts are reviewed | On the device | In the cloud service |
| Prompt content leaves the machine | Never | Sent to the service |
| Deployment model | Self-hosted, on-device | Cloud / API service |
| Coding-agent-native (wraps the CLI / PTY) | ✓ Claude Code · Codex · Copilot CLI | LLM-app / API security |
| Signals to security team | Redacted, content-free | Cloud-analyzed |
| Licensing | Open source (AGPL-3.0) | Proprietary |
| Account required to start | No (community agent) | Yes |
The honest take. Lakera Guard's cloud model is genuinely strong where it's aimed: catching prompt-injection and app-layer attacks across many production LLM applications at once, with detections that improve centrally for every customer. If you're securing a deployed AI product's request path, that is the right tool — and CuraIQ is not a replacement for it. CuraIQ is the right fit only when what you need to govern is the coding agents your developers run locally, and keeping prompt content on the device is a hard requirement.
Comparison is architecture-level and reflects the products' stated deployment models. CuraIQ keeps prompt content on the device; Lakera Guard analyzes prompts in its cloud service. Any capability figures are approximate — verify current specifics against each vendor's docs.
