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.

Can a detected injection still spend?
That's the gap the firewall closes — detection flags it, rules stop it.
