What does Securevector do?

Securevector is an open-source AI agent security platform that runs on your machine. It monitors every action your AI agents take — scanning prompts, auditing tool calls, and blocking threats before they reach the LLM. Think of it as a guardrail for agents like Claude Code, Codex, Copilot CLI, and Cursor. The local app works entirely offline, so no data leaves your infrastructure unless you opt into the cloud layer for team management.

The tool works by plugging directly into agent frameworks (LangChain, LangGraph, CrewAI, LlamaIndex) or via native plugins for specific agents. It intercepts each tool call, checks it against rules and an on-device ML model (Guardian ML) trained to catch obfuscated prompt injections and secret leaks. You get a live Agent Map showing every device, harness, agent, and tool as an interactive graph, plus turn-by-turn Runs with allow, block, or log-only verdicts. You can set tool permissions, rate limits, and daily cost budgets per agent. If you need fleet-wide oversight, Securevector Cloud consolidates all that data across enrolled devices, adds team alerts, and even generates custom rules tuned to your industry.

This is built for developers and security teams who run AI agents in production and need visibility and control without locking into a proprietary cloud. It's especially useful if you're using multiple agent frameworks or CLI-based agents and want a single pane of glass for security and cost. The local app is free and open-source, so you can start monitoring in minutes. The cloud tier is optional and aimed at teams that need centralized governance and ML-driven analytics.

Key features

What makes it stand out

On-device ML detects prompt injections, jailbreaks, and secret leaks without sending data to the cloud

Agent Map and turn-by-turn Runs give a live graph of every agent action with allow/block/log verdicts

Native plugins for Claude Code, Codex, Copilot CLI, and Cursor — no proxy or glue code needed

Tool permissions, cost tracking, and daily budgets let you control what agents can do and spend

SecureVector Cloud adds team alerts, ML analytics, and AI-generated custom rules for fleet-wide governance
