Prevalid

Overview

Prevalid functions as an execution governance layer for AI agents, enforcing security controls across the entire interaction lifecycle. It bridges the gap between autonomous agentic workflows and enterprise risk management by providing continuous oversight, Human-in-the-Loop (HITL) routing, and granular policy enforcement.

Key Capabilities

• prevalid_inbound_gate: Sanitizes incoming prompts by masking secrets and summarizing content before it reaches the LLM.
• prevalid_authorize_tool_call: Intercepts every tool execution request, requiring explicit approval before the action proceeds.
• prevalid_mask_pii: Detects and redacts sensitive personally identifiable information within data streams.
• prevalid_activate_kill_switch: Provides an immediate emergency override to halt all agent operations across a session.
• prevalid_audit_trail & prevalid_list_decisions: Generates comprehensive logs detailing the rationale behind every allow, deny, or pause decision.

Use Cases

• Sensitive Data Handling: Use prevalid_mask_pii to ensure customer records are redacted before being processed by third-party LLMs.
• High-Stakes Tool Execution: Implement prevalid_authorize_tool_call to ensure that agents cannot execute database deletions or external API writes without human verification.
• Emergency Containment: Trigger prevalid_activate_kill_switch if an agent starts hallucinating or performing unauthorized tasks, instantly locking down its capabilities.
• Governance Auditing: Review prevalid_list_decisions to generate compliance reports explaining why specific agent actions were blocked or permitted.

Who This Is For

Prevalid is designed for security engineers, AI implementation architects, and platform developers who need to deploy autonomous agents in regulated environments. It is intended for technical teams who require strict, auditable guardrails rather than "black box" agentic behavior.
