ASK HN: SAAS liability insurance?

We are a US-based, somehow successful, but still a small SAAS business, with many customers. We have a solid product and good T&C, but we were almost sued recently. As a founder, this was one of the most stressful experiences of my life. As much as we go crazy on keeping high quality, I know this is just a matter of time, a customer will claim our support or our product did something that cost them millions.

Do you have any liability insurance for your SAAS? When I search for liability insurance online, most results look super scammy. Any company you can recommend?
