Tools to track wallet activity

Are there any tools to monitor individual wallet activity? I am looking to track our customer wallets on their transaction history, asset holdings (ERC20 tokens, NFT holdings on ETH network) to have an idea of what kind of customers we have.

Etherscan allows this but I have to manually search addresses one-by-one. I was going to build my own data analysis tool using Etherscan API but before I do so, I want to confirm if there is any tool in the market that does this.
