Hidden costs
Beyond the line-item price, every runtime AI guardrail carries operating costs the vendor page does not surface. Plan for these in any board paper.
- Per-call latency overhead. Guardrail check sits in the request path; budget 50 to 300 ms extra per LLM call.
- False-positive remediation. Allocate engineering time to tune policies after every guardrail rule change.
- Logging and retention. Guardrail decisions need to land in your SIEM. See siemcostcalculator.com.
- On-call coverage. Treat AI security alerts like SOC alerts. See securityoperationscost.com.
- Procurement cycle time. Quote-only vendors add weeks of contract negotiation before the first invoice arrives.
