Lakera

Security layer for LLM applications, aimed at prompt injection, data loss, and related abuse on model inputs and outputs.

7.2/10
Overall Score
Conditional recommend

Lakera is a focused guardrail for apps that take untrusted input. It belongs in front of a model that can see tools or data, and it is not a full application security program.

Best for

Teams shipping LLM features that accept user input and can place a check on the request path.

Not ideal for

Buyers who want a one-time filter to replace app auth, data permissions, or a human review policy.

Verdict

Put Lakera on the path when users or documents can steer a model that has tools or private context. Tune it on your traffic so it blocks the cases you care about. It does not replace authorization on the tools the model can call. Skip it as a substitute for access control, or if you have no path to insert a check before the model acts.

Review Excerpts

Below are excerpts from public reviews. Our team scoured public reviews, forums, and chat rooms to get a balanced view of customers' experience with this company. Paid reviews and pay-for-play sites such as Clutch were excluded.

What people don’t like

“Most tools I've found (Lakera Guard, LLM Guard, Azure Prompt Shields) are still text-only in their public APIs. The research papers describe the attacks well but I haven't seen many production-grade defences for image/audio/document injection.”

What people don’t like

“Most of the defenses discussed here (Lakera, LLM Guard, Prompt Shields) are detection layers — they try to classify whether an input is malicious before it reaches the model. The problem with semantic attacks is exactly what you identified: you can't reliably detect "act as a SQL expert" as benign vs. malicious without full context.”
