I think Criminal IP’s Strength is 1. Blue ocean market 2. Various search engines 3. Various filters.
CTI market is blue ocean. so can get easily get a chance to be a pioneer. Second, Before, I use shodan to get IP info and use urlscan.io to get domain info but I can search ip, port, domain info on one product.
But the CTI market continues to grow, shodan and censys occupy a high market share in the market, and it is not easy for existing users to move.
So, I think Criminal IP must have its own strengths to bring in new customers and bring in existing customers.
