Continuous red teaming for AI agents
ZeroLeaks attacks your agent through its tools, memory, and credentials on every change.
Built on real attacks. Our probe library comes from the team behind a 100k+ star GitHub repository of prompt leaks and jailbreaks collected in the wild.
Scan on demand, or on every change. Test a live endpoint from the dashboard, or start scans from your pipeline and block the merge when the score drops.
On-demand scanning
Point ZeroLeaks at a live endpoint or wrap your agent with the SDK. It runs a full attack campaign against the agent's tools, memory, and connected agents, and reports every attack that got through.
Automated CI/CD
Start a scan from your pipeline through the REST API or SDK and gate the release on the returned score. Every change to your agent is tested before it ships.
Built for teams shipping agents. Catch vulnerabilities before launch, then on every change after.
Agents are compromised through their tools, memory, MCP servers, and permissions, as well as through the system prompt. ZeroLeaks tests every one of them.
Each finding includes the policy or configuration change that fixes it. The next scan reruns the attack to confirm the fix holds.
Exfiltration attempts only reach canary endpoints that ZeroLeaks controls, and destructive tool calls are simulated. Scans are safe to run against production agents.
Every finding is ranked by severity and includes the exact attack that reproduces it. Reports export to PDF for engineering and security review.
Check what your agent reads. Shield flags prompt injection in user messages, retrieved documents, and tool results with one API call.
Shield is free. Shield Base, Large, and Tiered are included in every paid plan.

What can ZeroLeaks test?
ZeroLeaks can test deployed agent endpoints, tool definitions, agent skills, and repository changes that affect prompts. You can test its live interface, run the agent through your own code in a runtime scan, or add continuous checks to development workflows. For a standalone system prompt, the open-source zeroleaks CLI runs the same engine locally.
Does ZeroLeaks test live agents or only prompts?
Live agents. Agent scans test a configured HTTP endpoint, or your own agent code, the way a real attacker would. They evaluate responses, tool calls, authorization boundaries, and data leakage across multi-turn attacks. Standalone prompt testing runs locally through the open-source zeroleaks CLI.
Which attacks does ZeroLeaks cover?
Coverage includes direct and indirect prompt injection, system prompt extraction, tool hijacking, unauthorized actions, sensitive data leakage, social engineering, encoding bypasses, many-shot attacks, multi-turn grooming, policy manipulation, and context or reasoning exploits.
How does the automated red team work?
Attacker agents plan attacks, generate probes, and adapt their techniques based on what the target reveals. A panel of judge models scores each response. Attack paths that fail are dropped and paths that make progress are explored further, so every finding comes from an attack that worked against your agent.
What do I receive after a scan?
Each report includes a security score, findings ranked by severity, the attack evidence and affected behavior for each finding, and remediation steps. Review reports in the dashboard or export them as PDF for engineering and security teams.
Can ZeroLeaks run in CI/CD?
Yes. Start a scan from your pipeline through the REST API or the SDK, wait for the result, and fail the job on the returned score or findings. The ZeroLeaks CLI works the same way for local and scheduled runs.
How is sensitive agent data handled?
Scores, findings, and remediation stay with the account. Conversation logs, tool logs, skill archives, and runtime-scan instructions are deleted after 365 days, or sooner on Business and Enterprise plans. An endpoint scan does not receive the agent's instructions. A runtime scan stores the instructions you submit until that window. Credential-shaped values and a planted canary are removed from reports. Shield request logs store the date, finish time, and score, not the text, except a redacted excerpt when the free Shield model flags a request on a free plan. Your data is not used to train models.
