sipi.bot vs Lakera Guard

Lakera Guard is a prompt-injection detection service. sipi.bot is a spend firewall. One detects the attack; the other makes the damage impossible.

What Lakera does well

Purpose-built prompt-injection detection at scale.

Strong API-level security layer for LLM apps.

Where it falls short

Detection is probabilistic — a bypass is always possible.

It flags content; it doesn't gate the money path.

Where sipi.bot wins

Deterministic rules on the spend path — they can't be injected.

Caps, allowlists, velocity limits, approvals.

When to use which

Lakera for content-layer detection; sipi.bot for the money layer. Defense in depth.

FAQ

Are they competitors?

No — detection and enforcement are different layers; use both.

Can a detected injection still spend?

That's the gap the firewall closes — detection flags it, rules stop it.
