TL;DR: AI agent security KPIs shift the conversation from control counting to measurable outcomes, with metrics for discovery coverage, runtime visibility, prompt injection detection, policy violations, remediation speed, and compliance, according to Akto. The governance lesson is that autonomous systems invalidate static security reporting and require continuous assurance.

By the numbers:
- The 94 percent of the actions that violated policies were blocked last month is an outcome.
Questions worth separating out
Q: How do organizations prove AI agent controls are actually working?
A: Organizations prove control effectiveness by showing which agents accessed which data, what actions they executed, and whether those actions stayed within approved task boundaries.
Q: Why do traditional vulnerability and scan metrics fall short for AI agents?
A: They describe deterministic software, not systems that can change behaviour while running.
Q: What do security teams get wrong about agent discovery coverage?
A: They treat discovery as if inventory equals control.
Practitioner guidance
- Instrument discovery and runtime telemetry together Track discovered agents, active tool calls, prompt events, and data access in the same control plane so gaps show up as blind spots instead of missing logs.
- Separate policy violations by failure type Break out sensitive-data access, unauthorized tool use, and restricted actions so IAM, data, and application teams can own the specific control that failed.
- Set response thresholds for remediation speed Define containment targets for credential revocation, tool disabling, or agent shutdown so mean time to remediate reflects actual operational readiness.

AI agent security has moved from posture management to runtime governance. Discovery counts and scan coverage are not enough when the actor can plan, call tools, and change state during execution. The important question is whether the enterprise can observe and constrain behaviour as it happens. That shifts the discipline from static inventory to continuous control validation, which is the only defensible model for agentic systems.
A few things that frame the scale:
- Only 52% of companies can track and audit the data their AI agents access, leaving 48% with a complete blind spot for compliance and breach investigation, according to the AI Agents: The New Attack Surface report.
- 80% of organisations report their AI agents have already performed actions beyond their intended scope, according to the AI Agents: The New Attack Surface report.
A question worth separating out:
Q: Who is accountable when an AI agent accesses regulated data improperly?
A: Accountability sits with the teams that govern the agent's identity, the data classification, and the policy that allowed the access path. If those controls are disconnected, no single owner can explain why the access existed or why it was not removed sooner. Shared context is what makes accountability traceable.
