> Since all conversation data passes through LLM, TTS, and STT layers, does these vendors store our data? If yes, how is the data secured?
We at Vapi by default use data to train our models but you can use HIPPA to disable data storage in our system. We don't know about other providers.
> What security measures does Vapi.ai implement to protect customer data and sensitive information such as credit card numbers, personal details (email addresses, phone numbers, bank account numbers), or any other confidential data shared during conversations?
For this we have an detailed guide over here

> Given that data can be fetched or pushed to external systems via tools triggered within conversations, how does Vapi.ai ensure the protection of sensitive data?
We have security walls so data is made accessible either to Vapi or it's owner using usually security policies such as ABAC, n/w-ing clusters, rate limting, public layers for API and so on...
> Does Vapi.ai implement data masking with dummy data before sending it to an LLM for processing?
Now we are PCI complaint so it is covered.
> Additionally, can customers use Vapi.ai with a zero data retention policy concerning data stored with external vendors such as LLMs, transcribers, etc.?
Yes using HIPPA you can disable the data retention.
