Introduction
Repello AI secures agentic workflows, MCP connections and chatbots. Its platform combines autonomous AI red teaming, runtime guardrails and continuous AI security monitoring for enterprises.
It targets threats such as prompt injection, where attackers embed instructions in inputs or external content to leak data or trigger unauthorised actions. Customers quoted include Lyzr, and the site offers a free red-teaming scan of your agent.
The free scan is a sensible first step, but the bigger question is ownership: who fixes a prompt-injection finding, and who maintains the guardrails afterwards? Agree on that before rolling out continuous testing, so findings turn into changes to prompts, tool permissions or runtime policies rather than a growing backlog.
Features
- Autonomous red teaming: Attack your agents.
- Runtime guardrails: Block attacks live.
- MCP security: Test MCP connections.
- Continuous monitoring: Ongoing assessment.
Pros
- Free scan: Try on your agent.
Cons
- Enterprise pricing: Contact sales.
Usage and Links (Example)
- Run the free red-teaming scan on an agent.
- Review findings.
- Deploy guardrails for issues you cannot fix in prompts.
