Voice agent testing for financial services
From balance inquiries to fraud detection, test every transaction
A wrong balance is a complaint. A leaked account number is a regulatory filing. Hamming simulates your customers, red-teams the agent before launch, and keeps the evidence your compliance team needs.
Hamming works with
All integrations
Generate financial transaction scenarios automatically
Create banking-specific test suites that cover transactions, fraud checks, and escalation workflows with production realism.
Test end-to-end transaction processing
- Test transfers, payments, and refund processes from initiation to confirmation
- Validate amount confirmation, recipient verification, and transaction authorization
- Validate secure DTMF handoffs and payment redirections during sensitive data entry
Validate authentication and data security flows
- Test multi-factor authentication using PINs, OTPs, and security questions
- Validate secure credential handling across sessions
- Test failed authentication attempts and session handling for sensitive customer data
Test fraud detection and prevention capabilities
- Simulate fraud scenarios like social engineering or unauthorized access attempts
- Test alert generation, transaction blocking, and escalation workflows
- Confirm accurate handling and traceability of fraud-related interactions
Catch hallucinations and compliance drift
Test across thousands of banking scenarios to validate transaction accuracy, compliance adherence, and model reliability across financial workflows.
Test financial regulatory compliance
- Test compliance with PCI DSS, GDPR, and regional financial data laws
- Validate required disclosures, consent collection, and opt-in/opt-out handling
- Check recording notices and customer authorization workflows
Test account management and servicing
- Test balance inquiries, transaction lookups, and account modifications
- Validate address changes, card replacements, and service requests
- Check that fee and interest rate disclosures are accurate
Red team financial voice agents
- Simulate jailbreaks, data extraction, and prompt manipulation attempts
- Test agent resilience under noise, code-switching, and cross-talk conditions
- Validate safeguards that prevent sensitive data disclosure and policy violations
Operational reliability for financial voice models
Continuously validate production voice agents for compliance, accuracy, and performance as prompts and models evolve.

“Our old testing vendor told us our voice agents were passing. Our customers and our own ears told us otherwise. 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.”

Frequently asked
questions.
Browse every answer on the FAQ pageYes. Hamming tests multi-factor authentication and data-handling flows to confirm secure account access and processing. We simulate PIN entry, OTP verification, security questions, and failed authentication scenarios.
Hamming checks that your agent never reads back, repeats, or logs a full card number, hands off to DTMF or a secure payment flow when it should, and records the evidence for your PCI assessor.
Yes. Hamming simulates suspicious transaction patterns and validates that your voice agent detects anomalies, triggers alerts, and follows proper verification protocols before approving high-risk transactions.
Select a testing platform that covers three key areas: security (authentication, PCI DSS compliance, fraud detection), regulatory adherence (GDPR, data privacy, disclosure handling), and operational reliability. Hamming generates scenarios for all three from your agent's prompt, your policies, and your production calls.
Setup takes about 10 minutes. We pull your agent configuration via API and auto-generate test scenarios specific to your workflows. You'll be running your first batch of tests in under 10 minutes.
Yes. We test the full range of account servicing: balance inquiries, transaction history lookups, fund transfers, bill payments, card replacements, and address changes. We validate that amounts and account details are captured accurately.
Hamming includes red teaming capabilities that simulate jailbreaks, data extraction attempts, and prompt manipulation. We test agent resilience under adversarial conditions and validate safeguards that prevent sensitive data disclosure.
Yes. Hamming runs batch testing with 10, 20, 50, or 100+ simultaneous test calls. This is critical for validating performance under peak conditions like market opens, end-of-month processing, or promotional campaigns.
No. We do not sell customer data, use it for training, or use it to benefit other customers. It is used to provide the service to you, and for nothing else.
