As service providers, we had used hardware security modules in our day-to-day operations at our first company. So we have first-hand experience of the difficulties of finding the right HSM for our needs, which seemed to be an impossible mission. The products available on the market lacked the appropriate features and the attitude of the vendor made things difficult for us as well: the pricing strategy was not transparent at all, the solutions could not be customized to their needs, and the support service was poor but expensive.
