As someone deeply familiar with this problem (ex-JupiterOne), I'd caution against asserting that 'deep level of customization' is a differentiator. Your buyer (CISO) and userbase (Sec Engs) are drowning. They (and I) don't want yet another product to build on top of. This is a key reason why Wiz is so successful -- an operator can turn Wiz on and immediately receive value, no adjustments or additions needed.
I'd strategically focus on making the 'actionability' part the cornerstone of the product and really become obsessed with making that part of your product incredible. The Goliath-killing story you need will be formed by figuring out how to get your product to the point where someone can turn it on and immediately receive value for the most impactful security problems first (ex: Log4J) and the total surface area of problems the product solves for second.
