omnia vs lakera

Lakera spots prompt attacks. Omnia stops the tool call they’re after.

Omnia stops the attack where it does harm, at the tool call. Lakera, now part of Check Point, detects prompt injection, including in tool results, and leaves the decision to you.

A tool result carries a hidden instruction to export the customer list.

on omnia

Whatever the model now believes, the export tool’s policy only allows exports by named roles, to approved destinations. The call is refused before it runs and the audit says why. Adversarial callers tried the same trick before release. docs

on lakera

Lakera returns a flagged result. You decide within your application what mitigating action to take. their docs

The action is stopped, not just flagged

If policy says no, or the broker can’t answer, the tool call doesn’t run. The block happens in the platform, with no handler to write in your application. docs enterprise

Lakera: Detection returns a flag; mitigation is your application’s job. source

Sensitive data never reaches the model

Named fields in a tool response are replaced before the model sees them, and sessions and memory are redacted before they’re stored. docs enterprise

Lakera: PII is detected and flagged. source

Red teaming that gates the release

Adversarial callers are part of every version’s test suite, run through its real tools, and the release waits on them. docs

Lakera: Red teaming is a separate product and service. source
