Test AI the Way Attackers Do

Knostic gives you the tools to simulate adversarial techniques and uncover risks before they become breaches.

How Knostic Takes Your Red Team to the Next Level

Simulate prompt injections

and jailbreaks to test how copilots and agents handle adversarial input.

Uncover oversharing

by mapping what AI assistants can actually surface across files, sites, and RAG systems.

Probe MCP servers and agents

for weak connectors, unsafe defaults, and excessive permissions.

Prioritized findings

with remediation guidance so testing translates into measurable security improvements.

Test your LLM for oversharing

Ever wonder what your Copilot or internal LLM might accidentally reveal? We help you test for real-world oversharing risks with role-specific prompts that mimic real workplace questions.

RAG Security Training Simulator

RAG Security Training Simulator is a free, interactive web app that teaches you how to defend AI systems — especially those using Retrieval-Augmented Generation (RAG) — from prompt injection attacks.

Made for Red Teams & Pen Testers

Surface hidden AI threats before adversaries do. Turn findings into additional funding for fixes.
