Ondrej Kováč - PeerSpot reviewer
Advanced cybersecurity solution for attack based vulnerability mng. and upskill platform for SOC.
While Cymulate's technology shows great promise and delivers excellent results, their approach to positioning the solution appears to overlap with other companies like Tenable, making them both direct and indirect competitors. Cymulate must refine their messaging and manage expectations effectively. In my experience, they need to be more attentive internally and mindful of potential negative impacts on customers. They exhibit a high degree of flexibility, which can result in sudden changes without adequate alerting. Communicating with them via phone for business matters can be challenging. On a scale from one to ten, I would rate Cymulate's technology level at eight, but their business level at four out of ten.
