Support and integration enhance security posture over three years

I don't know if there's something that could be improved. They surprise me. As I mentioned, I returned a month ago. I haven't fully investigated the complete system yet. I must say that we have been with them for around three years. This is amazing because throughout these three years, they have supported us every week. We meet weekly to review results and fix issues together. Apart from occasional days off, this weekly support has been consistent for three years. It's remarkable because many products are sold and then the product teams forget about you, but this isn't the case with Cymulate.
