AI agent security gateway
Route model and tool traffic through one enforcement point. Apply identity, rate, content, and action policy without rewriting the agent you already run.
AI agent security gateway
Protexct is the control plane for production AI agents. It inspects LLM and MCP traffic, blocks prompt injection, enforces runtime policy, and leaves behind evidence your team can act on.
One gateway for model requests, tool calls, credentials, policy, and audit evidence.
Activity from protected agents
What Protexct does
Most AI security products stop at a model prompt. Protexct protects the whole execution path: the context an agent reads, the MCP tools it discovers, the credentials it receives, and the action it tries to take.
Route model and tool traffic through one enforcement point. Apply identity, rate, content, and action policy without rewriting the agent you already run.
Scan inputs, retrieved context, tool descriptions, and outputs before an injected instruction can change an agent’s course of action.
Inspect MCP discovery, tools, parameters, and results across remote and local transports. Enforce a registry and stop poisoned tools at the boundary.
Turn novel attacks into regression tests. Nightly red teaming and measured model updates help controls improve as the threat distribution moves.
Keep policy, identity, prompt, tool activity, and outcome in an immutable event trail ready for investigation and evidence export.
Production proof
Fast enough to stay in the request path. Detailed enough to tell your team exactly what happened after a decision.

How it works
Protexct sits between the agent and the model provider. It makes the security decision in the request path, then records the context needed to understand and improve that decision.
Your agent sends a model request or tool action.
Identity, credentials, rate limits, and routing are applied.
Prompts, context, tool metadata, and outputs are classified.
Allow, redact, block, or request human approval.
Only an authorized, policy-compliant request continues.
Inspect
Model prompts, retrieved context, tool definitions, credentials, and responses are visible at the boundary.
Decide
GUARD and OPA can allow, redact, block, or pause for a human before an action runs.
Learn
Traces and red-team findings become regression tests for the next measured threat-model update.
Built for consequential workflows
Start with a single service boundary, then give security, compliance, and platform teams the same operational view.
Fintech
Protect underwriting, support, and operations agents from prompt injection while enforcing tool scopes, approval gates, and durable evidence for every sensitive action.
Healthcare
Inspect retrieved context and tool calls, redact sensitive data, and preserve a traceable record of what the agent saw, decided, and shared.
Enterprise AI teams
Standardize security across providers and frameworks with one gateway, a shared MCP registry, tenant-aware policy, and findings your platform team can act on.
Why teams choose Protexct
A concise view of the controls that matter when an agent can read data, call tools, and change the world.
