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.
