Can you buy stETH directly?

Excuse me, could you possibly elaborate on this matter? I'm somewhat intrigued about the prospect of acquiring stETH directly. Is it feasible to do so, and if so, how would the process work? Are there any specific platforms or exchanges that facilitate direct purchases of stETH? Additionally, are there any potential risks or considerations I should be aware of before proceeding with such a transaction? Your insights would be greatly appreciated.
