Runtime Security
Sits inline on every inference, tool call, and agent handoff, making per-action decisions in under 100ms to allow, restrict, challenge, deny, or monitor AI activity.
PromptHalo helps enterprises monitor AI behavior in real time, catching prompt injection, jailbreaks, data leakage, retrieval poisoning, unsafe tool actions, and behavioral drift before they become incidents. Purpose-built for agentic AI, it runs inline across inferences, tool calls, and handoffs, delivering fast decisions without touching proprietary models or forcing major code changes.

Inline AI monitoring and enforcement for safer enterprise agents, applications, workflows, and regulated customer interactions.
Sits inline on every inference, tool call, and agent handoff, making per-action decisions in under 100ms to allow, restrict, challenge, deny, or monitor AI activity.
Monitors AI application inputs and outputs in real time, detecting anomalies, trust issues, and risky behavior in milliseconds before problematic responses reach users.
Lets enterprises define custom rules that flag, log, transform, or block AI requests and responses inline, ensuring organizational policies are enforced at the point of action.
Identifies direct prompt injection, retrieval injection, and RAG poisoning attempts using embedding-based detection and a shared Threat Library trained by red-team findings.
Inspects AI responses in real time to stop sensitive information from being exposed across conversations, sessions, tenants, or multi-step agent workflows.
Tracks subtle changes in AI behavior across sessions, helping teams catch reliability, trust, and compliance issues before they compound into larger operational risks.
PromptHalo gives security and compliance teams a real-time control layer for AI applications, agents, RAG systems, and tool chains. Instead of reviewing incidents after delivery, it inspects activity on the wire, applies policy per action, and creates decision-level evidence. Teams can scale AI autonomy while containing prompt attacks, data exposure, unsafe execution, and regulatory risk.

PromptHalo is built for the security risks created by autonomous AI systems.
Purpose-built for tool calls, RAG retrieval, multi-agent handoffs, and autonomous AI decisions.
Inline runtime decisions happen in under 100ms before risky actions execute.
Deploys in under a day with no model retraining or code rewrite.
Creates tamper-evident, replayable logs mapped to major AI risk frameworks.
Runtime security and trust for agentic AI.
PromptHalo focuses on one critical problem: helping enterprises trust AI agents while they operate in real time. The platform tests AI the way attackers would, then turns those discoveries into runtime defenses across prompts, RAG layers, tool calls, and agent-to-agent handoffs. Built for security teams, regulated organizations, and enterprises deploying AI at scale, PromptHalo works across applications from any vendor without touching proprietary models. Its vision is to make agentic AI safe enough for sensitive transactions, compliance workflows, and customer interactions, while giving teams the evidence they need to prove control at every decision point.
Real-time AI monitoring protects users by inspecting prompts, responses, tool calls, and agent handoffs before outcomes are delivered or executed. PromptHalo can detect prompt injection, jailbreaks, data leakage, retrieval poisoning, unsafe actions, and behavioral drift in milliseconds. When risk appears, the system can allow, restrict, challenge, deny, or monitor the action while recording an audit trail.
