Validate every tool call before execution. Detect privilege escalation, monitor agent behavior, and block dangerous commands-all in real-time.
Intercept and validate every tool call before execution. Block dangerous operations like file deletion, shell commands, and unauthorized API calls.
Detect and block attempts to escalate privileges, such as agents trying to modify permissions or access restricted resources.
Track agent behavior over time to establish baselines and detect anomalies like unusual tool usage patterns or rapid-fire operations.
Require human approval for sensitive operations like sending emails, modifying user data, or executing financial transactions.
Isolate agent sessions to prevent cross-contamination and limit the blast radius of compromised agents.
Get instant notifications when suspicious agent behavior is detected. Integrate with Slack, PagerDuty, and webhooks.
Every tool call from your AI agent passes through PromptGuard's security layer before execution.
We validate the tool, arguments, and context against your security policies and behavioral baselines.
Safe operations execute immediately. Dangerous or suspicious calls are blocked or require human approval.
