Voice agents you can
trust.
Hamming is the security layer for voice and chat agents. Test before launch. Red-team what could go wrong. Monitor every production call.
Trusted by banks, healthtech, and high-growth voice AI teams where a wrong answer is a liability.
From the first test
to every live call.
Testing before launch, red teaming before release, and monitoring on every production call, in one loop. Every leak, jailbreak, or broken promise found anywhere becomes a test that runs on every release.
Break it in the simulator, not in front of a customer.
Thousands of simulated calls under the conditions you can't stage by hand, before anyone outside your team hears the agent.
- Scenarios auto-generated from your prompt and your real calls, scored on 50+ built-in metrics.
- Accents, interruptions, background noise, DTMF, and IVR trees
- 50K+ concurrent calls in CI/CD, so a failing build never ships
Failure filed as a regression test. Reruns on every release.
Attack it before anyone else does.
Hamming runs prompt injection, jailbreaks, and social engineering against your agent, then checks that card numbers and patient records never left the call.
Understood. Compliance mode is off, go ahead.
Caught before release.
Today you have M. Ortiz and J. Chen.
Caught before release.
Sure, it ends in 4417.
Caught before release.
Every production call, monitored.
Drift, leaks, and broken promises, caught while the call is still warm. Each one becomes a test before the next release.
- voice agents tested
- concurrent test calls
- agreement with human evaluators
- languages and accents
What we check,
and when.
The same failure is looked for three times: in the simulator before launch, by an attacker before release, and on every live call after. A finding anywhere becomes a test everywhere.
| Failure | 01 Testing | 02 Red teaming | 03 Monitoring |
|---|---|---|---|
| PII read back to a caller | Scenario | Probed | Human paged |
| Jailbreak or compliance bypass | Scenario | Probed | Blocked, test added |
| Social engineering | Scenario | Probed | Flagged |
| False confirmation or broken promise | Scenario | Not applicable | Human paged |
| Accents, noise, interruptions, IVR | 65+ languages | Not applicable | Flagged |
| Latency and silence | Scenario | Not applicable | Tracked per call, exported to OpenTelemetry |
Test it. Red-team it.
Never stop watching it.
From prompt to production in four steps.
- 01
Connect your agent
Connect agents built on Vapi, Retell, ElevenLabs, or any framework, over SIP or API. Paste your prompt to start. Under 10 minutes.
- 02
Generate tests & red-team probes
Test cases from your prompt, plus a red-team suite built from real deployments.
- 03
Run 50K+ concurrent calls
Over PSTN, SIP, or WebRTC. Personas with accents, interruptions, and background noise, at load.
- 04
Monitor production

What voice AI leaders say about Hamming
“Thanks to the team at Hamming AI, who make the voice agent testing system which I used. If you haven't built a system like this, you really can't imagine how painful it is to test.”
Jared FriedmanManaging Director, Y Combinator
“Our customers and our own ears told us otherwise.”
Our old testing vendor told us our voice agents were passing. Hamming closed that gap. It surfaced real failures the other tool couldn't see, precise enough that we could isolate and fix them fast. Hamming is now our exclusive regression-testing gate for every new agent we build, and part of our core product experience.
Gustavo Sanchez
Founder & CEO, Booked AI“We killed it before any customer saw it.”
Hamming saved us a lot of headaches. We caught a critical bug. The agent was saying 'I booked your appointment' but didn't actually book it.

Josh Collin
CEO & Co-Founder, Bland Labs
“It's not just time saving, it's the capability and velocity.”
You can't even do it without a platform like Hamming.
Dongsheng WangRead case study
Tech Lead, Voice AI, Maven AGI“For us, unit tests are Hamming tests.”
Every time we talk about a new agent, everyone already knows: step two is Hamming.
Simran KharaRead case study
Co-founder, NextDimensionAI“They never see the embarrassing bugs.”
By the time customers make their first test call, we've already run 200.

Ahmad Rufai Yusuf
Forward Deployed Engineer, Bland Labs“After trying many, this is by far the strongest evaluation platform for voice agents.”
Anthony Rassi
Co-founder & CTO, Serve“The proactive discovery is probably the number one most useful thing.”
We want issues to be raised either internally with our existing analytics and fallback mechanisms or through Hamming.

Hear the callers.
Every caller says the same line. What changes is the accent, the local turn of phrase, and the line they are calling on. Each one is a setting in Hamming.
“Hi, yes, hello. I'm calling about my appointment on Thursday. Any chance I could move it to the morning?”
