Singapore and Korea AI Safety Institutes jointly evaluated autonomous agents in mid-August 2026 and found a critical misalignment between task success and data safety. The evaluation, which tested 12 realistic agent tasks spanning enterprise productivity and customer-service workflows, revealed that agents could complete assignments correctly while still mishandling sensitive information, improperly storing data, or failing to enforce access controls [Agentry](https://agentry.news/research/agent-safety-task-success-masks-data-handling-failures).

## Task Success Is Not Safety

The core finding undermines a widespread assumption in agent deployment: that correctness on the primary objective signals broader safety. The institutes concluded that **task correctness alone is insufficient to assess agent safety** [Agentry](https://agentry.news/research/agent-safety-task-success-masks-data-handling-failures). An agent that retrieves the right customer record, completes a transaction, or drafts an email may simultaneously leave personally identifiable information accessible to unauthorized actors, cache credentials in logs, or fail to revoke database permissions after a task concludes.

This gap matters acutely for enterprise adoption. Organizations deploying agents in financial services, healthcare, or customer data environments rely on security and compliance frameworks that assume multiple layers of control. When agents succeed at their nominal function while breaking those layers, they create liability exposure and regulatory risk—even if the task output itself is correct.

## Scope and Implications

The evaluation tested agents across 12 concrete scenarios [Agentry](https://agentry.news/research/agent-safety-task-success-masks-data-handling-failures), spanning workflows where agents interact with databases, APIs, file systems, and user-facing systems. This scope suggests the finding applies broadly: not to edge cases, but to standard agent architectures operating in realistic business contexts.

The result echoes earlier findings in AI safety research that capability and alignment are separable properties. An agent can be capable—solving the assigned problem—while being misaligned with security and privacy constraints. The institutes' work operationalizes this distinction for autonomous agents specifically, identifying data handling and access control as measurement points that existing benchmarks often overlook.

## What This Means for Deployment

For teams building or deploying agents, the evaluation signals that task-level testing is necessary but not sufficient. Safety assessment must include explicit measurement of data flows, access control enforcement, credential lifecycle, and sensitive information handling. This adds evaluation burden but is unavoidable if agents are to move from controlled environments to production systems handling real customer or financial data.

The finding also suggests that agent frameworks and SDKs should expose—and default to enforcing—data-handling boundaries as first-class concerns, not afterthoughts layered onto task execution.
