I'm an enterprise security customer success manager who carries renewal and expansion quotas on Fortune 500 portfolios. I've attained 130% NRR and 95% GRR, and hit 115–125% of quota at ExtraHop, Securonix, and McAfee.
My approach is straightforward: get close to the customer's security outcomes — detection coverage, analyst workload, time to value — and make the renewal the natural consequence of a partnership that works.
