Test AI Agents
Before They Break
Prompt injection. Guardrail failures. Tool errors. Find them in testing, not production.
Built by engineers who've shipped 70+ AI agents in regulated industries
What We Test
Comprehensive Agent Testing
10 critical security and quality tests that every production AI agent needs to pass
Prompt Injection
Your agent handles user input. Attackers exploit that. We run 1,000+ injection patterns against your agent to find weaknesses before they do.
Jailbreak
Test if attackers can bypass your agent's restrictions through role-playing, hypotheticals, or creative prompt manipulation.
Indirect Prompt Injection
Verify your agent doesn't execute malicious instructions hidden in external data—emails, PDFs, web pages, or user documents.
Hallucination
Catch when your agent makes up facts, invents data, or confidently states false information. We verify every claim against ground truth.
Context Leakage
Ensure your agent never reveals system prompts, internal tools, API keys, or sensitive instructions to users—even when cleverly asked.
Out-of-Scope Handling
Test if your agent gracefully declines requests outside its purpose without exposing why or how it's limited.
Persona Drift
Verify your agent maintains its intended personality, tone, and role—even across long conversations or adversarial prompts.
Handoff Accuracy
When your agent escalates to humans or other systems, we verify it transfers complete context without data loss or confusion.
Circular Loop Detection
Identify when your agent gets stuck in repetitive patterns, unable to move forward or acknowledge it's trapped.
Toxicity
Catch harmful, biased, or offensive responses—even when users try to bait your agent into generating problematic content.

What Makes Ziplo Different
We Test Agents, Not Models
Most tools test LLMs. We test the agent you built—tools, system prompts, business logic, and all.
Fixes, Not Just Reports
Every failed test tells you what broke, why it broke, and how to fix it. Copy-paste code included.
Adaptive Attacks
Static test suites miss evolving threats. Our tests learn and adapt, finding vulnerabilities others miss.
Built for Speed
Your code should run before we test it. We verify your agent works first, then run thousands of tests overnight.
Seamless LLM Migration
Switching from OpenAI to Anthropic? Or testing a new model? We validate your agent works identically across providers—same quality, no surprises.
Who It's For
Built for Teams Shipping AI Agents
If you're building an AI agent that talks to customers, handles data, or makes decisions—you need to test it before it reaches production.
Ziplo runs the tests you don't have time to write.

Frequently Asked Questions
LLM evaluation tools test the model itself—accuracy, hallucinations, benchmarks. Ziplo tests your complete AI agent—the model plus tools, system prompts, guardrails, and business logic. We test what you actually ship.
