Lakera Alternative - Firewall, Permissions, and Audit in One
Lakera is strong at prompt-injection guardrails. Agentshield is the alternative for teams that also need tool and data permissions, monitoring, and a full audit trail in one plane.
Direct answer
A Lakera alternative is a tool that protects AI agents without limiting you to prompt-injection guardrails alone. Agentshield is a runtime control plane that blocks prompt injection and also enforces tool and data permissions, monitors every action, gates high-risk actions for human approval, and writes an immutable audit trail. It is stack-neutral across OpenAI, Anthropic, LangChain, CrewAI, and MCP, with prices on the page rather than a sales call.
Where Lakera is strong
Lakera is a well-regarded choice for LLM input and output guardrails, particularly prompt-injection detection, and many teams adopt it for that specific slice.
Where Agentshield is the alternative
Agentshield combines a prompt-injection firewall with least-privilege tool and data permissions, real-time monitoring, human-approval gates, and an immutable audit trail in a single runtime control plane, so you do not bolt together separate tools to govern an agent. Pricing is transparent and self-serve.
Side by side
Agentshield vs Lakera, honestly.
| Dimension | Agentshield | Lakera |
|---|---|---|
| Prompt-injection firewall | Runtime prompt-injection detection on every untrusted input. | Strong prompt-injection and content guardrails. |
| Tool and data permissions | Least-privilege permissions enforced at the action boundary. | Focused on input and output guardrails rather than tool access control. |
| Monitoring and audit | Real-time monitoring plus an immutable audit trail of every action. | Logging around its guardrail decisions. |
| Human approval gates | Built-in human-in-the-loop gates for high-risk actions. | Not the core focus of the product. |
| Pricing | Transparent, self-serve prices on the page. | Mix of self-serve and sales-led depending on scale. |
