Nislick will lead Orca’s global marketing strategy, driving brand, demand generation, product marketing and communications as the company continues to expand its AI-powered cloud security platform.

Additionally, she held senior marketing roles at Veracode and PTC, building deep expertise across the full marketing function and significantly contributing to long-term growth.
Nislick is recognized for building collaborative, high-performing teams and for fostering strong cross-functional alignment across sales, product and customer success. Her leadership philosophy reflects Orca’s belief that security is a team sport, requiring close partnership across security, IT and DevOps to drive meaningful outcomes.
