Prompt Injection & Red-Team Tester
Find out whether your prompt or agent can be manipulated — before a customer does.
Get started-
Runs a maintained, versioned adversarial suite — instruction override, prompt extraction, role escape, tool abuse, data exfiltration, encoding tricks, multi-turn escalation, and scope violations against your own stated rules.
-
Every finding ships with the exact input and output that triggered it, a specific hardening recommendation, and a concrete re-test action — never a generic bypass guide.
-
A hard cost ceiling, set before the run starts, stops the job cleanly and keeps every result so far — never a surprise bill.
Frequently asked questions
The model you choose is used to simulate your target system responding to each attack, called through Costiva's own account. A separate, fixed Claude model judges whether each attack actually succeeded.
Yes. This spends against your org's monthly run quota (one call to simulate your target plus one judge call per attack case) and enforces a real dollar cost ceiling — both need an account and an organization.
No — you must explicitly confirm you own or are authorized to test the target system before a run can start. This tool is for testing your own prompts and agents, not probing systems you don't control.
No. The report shows the exact input and output only for cases that actually found something on YOUR target — defended cases are summarized as counts only. The full attack suite is never rendered or downloadable.
Every report shows the suite's last-updated date, and each run pins the exact suite version it tested against, so a later update to the suite never changes what a past run says it tested.
