Frequently asked questions
What does an AI agent security audit cost?
A focused internal checklist may cost only a few thousand dollars in labor. A boutique consultancy audit typically runs $10k–$50k. A full red-team simulation with remediation for a regulated financial or healthcare agent can exceed $100k.
Which areas drive the most audit hours?
Tool/function-call hijacking, prompt injection, and sensitive-data handling usually consume the most hours because they require custom adversarial tests and manual review of outputs.
Should I use internal staff or an external firm?
Internal staff know the system but may miss novel attack patterns. External firms bring fresh eyes and can produce reports for regulators, customers, or SOC 2 auditors. A hybrid mix is common.
How do automation tools change the cost?
Automated prompt scanners and SAST tools reduce manual test hours, but they still require triage, validation, and remediation. They are most cost-effective for repeated regression testing.
How often should we re-audit an AI agent?
Re-audit after any major model change, tool addition, or data-source change. Many teams run a light audit quarterly, a standard audit twice a year, and a red-team exercise annually or before a major launch.
